DESCRIPTION

Dimensions in millimeters

The SMTPB series are designed for protecting sensitive

telecommunication equipment against lightning and

transient voltages induced by AC power lines.

SCHEMATIC DIAGRAM

The devices provide bidirectional protection by crowbar

action.Their characteristic response to transien over-

voltages makes them particularly suited to protect volatge

sensitive telecommunication equipment.

TEST PROCEDURE :

Pulse Test duration (tp = 20ms):

- For Bidirectional devices = SwitchK is closed

- For Unidirectional devices = Switch K is open.

V_OUTSelection

- Device with V_BO< 200 Volt

- V_OUT= 250 V_RMS, R1 = 140 Ω.

- Device with V_BO200 Volt

- V_OUT= 480 V_RMS, R2 = 240Ω.

TEST CIRCUIT 2 FOR I_HPARAMETER:

D.U.T.

V^BAT=-48V

Surge generator

This is a GO-NO GOTest which allows to confirm the holding current (I_H) level in a functionaltest circuit.

TEST PROCEDURE :

1) Adjust the current level at the IH value by short circuiting the D.U.T.

2) Fire the D.U.T with a surge current : Ipp = 10A , 10/1000µ s.

3) The D.U.T will come back off-state within 50ms max.
