Description

The HSMS-2700 series of Schottky diodes, commonly referred to as clipping /clamping diodes, are optimal for circuit and waveshape preservation applications with high speed switching. Ultra-low series resistance, R makes them ideal for protecting sensitive circuit elements against higher current transients carried on data lines. With picosecond switching, the HSMS-270x can respond to noise spikes with rise times as fast as 1 ns. Low ca- pacitance minimizes waveshape loss that causes signal degradation.

The SOT-323 products, with their copper leadframes, can safely handle almost twice the current of the larger SOT-23 diodes. Note that the term “ambient temperature” refers to the temperature of the diode’s leads, not the air around the circuit board. It can be seen that the HSMS-270B and HSMS-270C products in the SOT-323 package will safely withstand a steady-state forward current of 550 mA when the diode’s terminals are maintained at 75°C. For pulsed currents and transient current spikes of less than one microsecond in duration, the junction does not have time to reach thermal steady state. Moreover, the diode junction may be taken to temperatures higher than 150°C for short time-periods without impacting device MTTF. Because of these factors, higher currents can be safely handled. The HSMS-270x family has the highest current handling capability of any Avago diode.
