TRISILTM FOR HIGH DEBIT RATE
TELECOM LINES PROTECTION
PRELIMINARY DATASHEET
FEATURES
n Bidirectional crowbar protection
n Low capacitance : C = 30 PF TYP @ 50V
n Low leakage current : IR = 2 µA MAX
n Repetitive peak pulse current :
IPP = 100 A (10/1000µS)
n Holding current: IH = 150 mA
MAIN APPLICATIONS
Any sensitive equipment requiring protection
against lightning strikes and power crossing:
n Analog and digital line cards
(xDSL, T1/ E1, ISDN...)
n Gas tube replacement
n Terminals and transmission equipment
SMB
DESCRIPTION
The SMP100LC-xxx series is a very low
capacitance transient surge arrestor designed
for the protection of high debit rate
communication equipment. Its low capacitance
avoid any distorsion of the signal. It can also

BENEFITS
n No ageing and no noise
n Short circuit in failure mode, thus still ensuring
protection
n Board space saving

FUNCTIONAL HOLDING CURRENT (IH) TEST CIRCUIT 1 : GO-NO GO TEST
VBAT = - 48 V

Surge generator
This is a GO-NO GO test which allows to confirm the holding current (IH) level in a functional test circuit.
TEST PROCEDURE :
- Adjust the current level at the IH value by short circuiting the D.U.T.
- Fire the D.U.T. with a surge current : Ipp = 10A, 10/1000 µs.
- The D.U.T. will come back to the off-state within 50 ms max.
