SMP50 / SMTPA / TPA
Trisil™ for telecom equipment protection
Features
■ Bidirectional crowbar protection
■ Voltage range from 62 V to 320 V
■ Low capacitance from 12 pF to 20 pF @ 50 V
■ Low leakage current : IR = 2 µA max
■ Holding current: IH = 150 mA min
■ Repetitive peak pulse current :
IPP = 50 A (10/1000 µs)
Main applications
Telecommunication equipment such as:
■ Analog and digital line cards (xDSL, T1/E1,
ISDN, ...)
■ Terminals (phone, fax, modem, ...) and central
office equipment
Description
These Trisil series have been designed to protect
telecommunication equipment against lightning
and transient induced by AC power lines.
They are available in SMA, SMB and DO-15
packages.
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 various
standards such as UL1950, IEC950 / CSA C22.2,
UL1459 and FCC part 68.
Trisils have UL94 V0 approved resin.
SMA and SMB packages are JEDEC registered
(DO-214AC and DO-214AA).
Trisils are UL497B approved (file: E136224).

TEST PROCEDURE
Pulse test duration (tp = 20ms):
● for Bidirectional devices = Switch K is closed
● for Unidirectional devices = Switch K is open
VOUT selection:
● Device with VBO > 200V ➔ VOUT = 250 VRMS, R1 = 140Ω
● Device with VBO ≥ 200V ➔ 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 50ms maximum.
