The high power 2651A SourceMeter SMU Instrument is specifically designed to characterize and test high power electronics. This SMU instrument can help you improve productivity in applications across the R&D, reliability, and production spectrums, including high brightness LEDs, power semiconductors, DC-DC converters, batteries, solar cells, and other high power materials, components, modules, and subassemblies. The 2651A offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters. It can be used as a:

• Semiconductor characterization instrument
• V or I waveform generator
• V or I pulse generator
• Precision power supply
• True current source
• Digital multimeter (DCV, DCI, ohms, and power with 6½-digit resolution)
• Precision electronic load Key Features
• Source or sink: – 2,000 W of pulsed power (±40 V, ±50 A) – 200 W of DC power (±10 V @ ±20A, ±20 V @ ±10 A, ±40 V @ ±5 A)
• Easily connect two units (in series or parallel) to create solutions up to ±100 A or ±80 V
• 1 pA resolution enables precise measurement of very low leakage currents
• 1 μs per point (1 MHz), 18-bit sampling, accurately characterizes transient behavior

Each mode is defined by its independent analog-to-digital (A/D) converters. The Digitizing Measurement mode enables 1 µs per point measurements. Its 18-bit A/D converters allow you to precisely measure transient characteristics. For more accurate measurements, use its Integrating Measurement mode, which is based on 22-bit A/D converters. Two A/D converters are used with each measurement mode (one for current and the other for voltage), which run simultaneously for accurate source readback that does not sacrifice test throughput. 0 25 50 75 100 125 150 175 200 Voltage (V) Current (A) Time (µs) Volts Current The dual digitizing A/D converters sample at up to 1 μs/point, enabling full simultaneous characterization of both current and voltage waveforms. High Speed Pulsing The 2651A minimizes the unwanted effects of self heating during tests by accurately sourcing and measuring pulses as short as 100 μs. Additional control flexibility enables you to program the pulse width from 100 μs to DC and the duty cycle from 1% to 100%. A single unit can pulse up to 50 A; combine two units to pulse up to 100 A.

Through TSP-Link Technology technology, multiple 2651As and selected Series 2600B SMU instruments can be combined to form a larger integrated system with up to 64 channels. Precision timing and tight channel synchronization are guaranteed with built-in 500 ns trigger controllers. True SMU instrument-per-pin testing is assured with the fully isolated, independent channels of the SourceMeter SMU instruments. 26xxB 2651A 2651A Up to 100 A TSP-Link LXI or GPIB to PC Controller Keithley’s TSP and TSP-Link Technologies enable true SMU-per-pin testing without the power and/or channel limitations of a mainframe-based system. Also, when two 2651As are connected in parallel with TSP- Link Technology, the current range is expanded from 50 A to 100 A. When two units are connected in series, the voltage range is expanded from 40 V to 80 V. Built-in intelligence simplifies testing by enabling the units to be addressed as a single instrument, thus creating an industry-best dynamic range (100 A to 1 pA). This capability enables you to test a much wider range of power semiconductors and other devices.

KickStart start-up software lets users be ready to make measurements in minutes. Standard Capabilities of Series 2600B SMU Instruments Each 2651A includes all the features and capabilities provided in most Series 2600B SMU instruments, such as:

• Ability to be used as either a bench-top I-V characterization tool or as a building block component of multiple-channel I-V test systems
• ACS Basic Edition software for semiconductor component characterization (optional). ACS Basic now features a Trace mode for generating a suite of characteristic curves.
• Keithley’s Test Script Processor (TSP ®) Technology, which enables creation of custom user test scripts to further automate testing, and also supports the creation of programming sequences that allow the instrument to operate asynchronously without direct PC control.
• Parallel test execution and precision timing when multiple SMU instruments are connected together in a system
• LXI compliance
• 14 digital I/O lines for direct interaction with probe stations, component handlers, or other automation tools
• USB port for extra data and test program storage via USB memory device Instrument Control Start-up Software KickStart instrument control/start-up software enables users to start making measurements in minutes without programming. In most cases, users merely need to make some quick measurements, graph the data, and store the data to disk for later analysis in software environments such as Excel. KickStart offers:
• Configure and control up to four SMU instruments for DC or Pulsed I-V test in either the same app, same project, or a combination of the two.

2400 Graphical Series, 2400 Standard Series (DC only),

2600B Series, 2651A, 2657A, and 6430 SourceMeter ® SMU (DC only) instruments.

• Differentiate SMU instrument channels and their measurement data using labels that are relevant to your device or module.

Buffer Size, without timestamp and source setting >140,000 samples. WWW.TEK.COM | 11 DATASHEET2651A 50 A, High Power System SourceMeter® SMU Instrument

System Expansion The TSP-Link ® expansion interface allows TSP-enabled instruments to trigger and communicate with each other. Cable type: Category 5e or higher LAN crossover cable. Three meter (9.84 ft) maximum between each TSP-enabled instrument. A maximum of 32 TSP-Link nodes can be interconnected. Each source-measure instrument uses one TSP-Link node. Timer Free-running 47-bit counter with 1 MHz clock input. Resets each time instrument power is turned on. If the instrument is not turned off, the timer is reset to zero every 4 years. Timestamp TIMER value is automatically saved when each measurement is triggered. Resolution 1 µs. Timestamp Accuracy ±100 ppm. General Digital I/O Interface +5VDC 5.1 kΩ 100 Ω +5V Pin (on DIGITAL I/O connector) Digital I/O Pin (on DIGITAL I/O connector) GND Pin (on DIGITAL I/O connector) Rear Panel 600 mA Solid State Fuse Read by firmware Written by firmware Connector 25-pin female D. Input/Output Pins 14 open drain I/O bits. Absolute Maximum Input Voltage 5.25 V. Absolute Minimum Input Voltage –0.25 V. Maximum Logic Low Input Voltage 0.7 V, +850 μA max. Minimum Logic High Input Voltage 2.1 V, +570 μA. Maximum Source Current (flowing out of digital I/O bit) +960 μA. Maximum Sink Current At Maximum Logic Low Voltage (0.7) –5.0 mA. Absolute Maximum Sink Current (flowing into digital I/O pin) –11 mA. 5 V Power Supply Pin Limited to 250 mA, solid-state fuse protected. Output Enable Pin Active high input pulled down internally to ground with a 10 kΩ resistor; when the output enable input function has been activated, the 2651A channel will not turn on unless the output enable pin is driven to >2.1 V (nominal current = 2.1 V/10 kW = 210 μA). 12 | WWW.TEK.COM DATASHEET2651A 50 A, High Power System SourceMeter® SMU Instrument
