Technical content

LS5060B/LS5120B DIL8 TRISIL TM BIDIRECTIONAL CROWBAR PROTECTION. BREAKDOWN VOLTAGES RANGE: 18V, 60V and 120V. HOLDING CURRENT = 200mA min. HIGH SURGE CURRENT CAPABILITY I PP = 100A 10/1000µs

FEATURES

The LS50xxB series has been designed to protect telecommunication equipment against lightning and transients induced by AC power lines. Its high surge current capability makes the LS50xxB a reliable protection device for very ex- posed equipment, or when series resistors are very low.

TEST CIRCUIT 1 FOR IBO and VBO parameters: 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 . TEST CIRCUIT 2 for IH parameter. This is a GO-NOGO Test which allows to confirm the holdingcurrent (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.
