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

1/ Adjust the current level at the I value by short circuiting the AK of the D.U.T.

2/ Fire the D.U.T. with a surge current

➔I=

10A, 10/1000µs.

3/ The D.U.T. will come back off-state within 50ms maximum.

This is a GO-NOGO test which allows to confirm the holding current (I ) level in a

functional test circuit.

In order to meet environmental requirements, ST offers these devices in ECOPACK®

packages. These packages have a lead-free second level interconnect. The category of

second level interconnect is marked on the package and on the inner box label, in

compliance with JEDEC Standard JESD97. The maximum ratings related to soldering

conditions are also marked on the inner box label. ECOPACK is an ST trademark.

ECOPACK specifications are available at: www.st.com.
