TRISIL™ FOR TELECOM EQUIPMENT PROTECTION REV. 11 SMB (JEDEC DO-214AA) June 2005

FEATURES

■ Bidirectional crowbar protection ■ Voltage range from 8V to 400V ■ Low capacitance from 20pF to 45pF @ 50V ■ Low leakage current : IR = 2µA max ■ Holding current: IH = 150 mA min ■ Repetitive peak pulse current: IPP = 100 A (10/1000µs) MAIN APPLICATIONS Any sensitive equipment requiring protection against lightning strikes and power crossing. These devices are dedicated to central office pro- tection as they comply with the most stressfull standards. Their Low Capacitances make them suitable for ADSL.

DESCRIPTION

The SMP100LC is a series of low capacitance transient surge arrestors designed for the protec- tion of high debit rate communication equipment. Its low capacitance avoids any distortion of the sig- nal and is compatible with digital transmission line cards (xDSL, ISDN...). SMP100LC series tested and confirmed compati- ble with Cooper Bussmann Telecom Circuit Pro- tector TCP 1.25A. BENEFITS Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. They are used to help equipment to meet main standards such as UL60950, IEC950 / CSA C22.2 and UL1459. They have UL94 V0 approved resin. SMB package is JEDEC registered (DO-214AA). Trisils comply with the following standards GR-

1089 Core, ITU-T-K20/K21, VDE0433, VDE0878,

IEC61000-4-5 and FCC part 68.

Following figure shows the test method of the board having Fuse and Trisil. Following curve shows the turn on of the Trisil during lightning surge. These topologies, using SMP100LC from ST and TCP1.25A from Cooper Bussmann, have been functionally validated with a Trisil glued on the PCB. Following example was performed with SMP100LC-270 Trisil. For more information, see Test conditions: 2/10µs + and -2.5 and 5kV 500A (10 pulses of each polarity), T amb = 25°C Test result: Fuse and Trisil OK after test in accordance with GR1089 requirements Following curve shows Trisil action while the fuse remains operational. In case of high current power cross test, the fuse acts like a switch by opening the circuit.
