SMP50

■ Holding current: I = 150 mA min

■ Repetitive peak pulse current :

= 50 A (10/1000 µs)

Main applications

Telecommunication equipment such as:

■ Analog and digital line cards (xDSL, T1/E1,

DO-15

TPA

ISDN, ...)

■ Terminals (phone, fax, modem, ...) and central

office equipment

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).
