PROGRAMMABLE BREAKDOWN VOLTAGE UP TO 250 V PROGRAMMABLE CURRENT LIMITATION FROM 40 mA TO 500 mA SURGE CURRENT CAPABILITY IPP = 30A 10/1000µs

FEATURES

Dedicated to sensitive telecom equipment protection, this device can provide both voltage and current triggered protection with a very tight tolerance. The breakdown voltagecan be easily programmed by using an external zener diode. A multiple protection mode can be also performed when using several zener diodes, providing to each line interface an optimized protectionlevel. The current limiting function is achieved with the use of a resistorbetween the gate and the cathode. The value of the resistor will determine the level of the desired current.

TEST PROCEDURE : Pulse Test duration (tp = 20ms): - For Bidirectional devices = Switch K is closed - For Unidirectionaldevices = Switch K is open. VOUT Selection - Device with VBO < 200 Volt -VOUT = 250 VRMS ,R1 = 140Ω . - Device with VBO ≥ 200 Volt -VOUT = 480 VRMS ,R2 = 240Ω . This is a GO-NOGO Test which allows to confirm the holding current (IH ) level in a functional test circuit. TEST PROCEDURE : 1) Adjust the current level at the IH value by short circuiting the AK of the D.U.T. 2) Fire the D.U.T with a surge Current : Ipp = 10A , 10/1000µs. 3) The D.U.T will come back off-state within 50 ms max.
