STMicroelectronics 

SMP30

Trisil™ for telecom equipment protection

Features

■ Bidirectional crowbar protection

■ Voltage range from 62 V to 270 V

■ Low capacitance from 10 pF

to 20 pF typ.@ 50 V

■ Low leakage current: IR = 2 µA max.

■ Holding current: IH = 150 mA min.

■ Repetitive peak pulse current:

IPP = 30 A (10/1000 µs)

Benefits

■ Trisils are not subject to ageing and provide a

fail safe mode in short circuit for a better

protection.

■ This device can be used to help equipment

meet various standards such as UL1950,

IEC950 / CSA C22.2, UL1459 and FCC part

68.

■ Trisils have UL94 V0 approved resin.

■ SMA package is JEDEC registered

(DO-214AC).

■ Trisils are UL497B approved (file: E136224).

Applications

Telecommunication equipment such as:

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

ISDN...).

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

office equipment.

Description

The SMP30 series has been designed to protect

telecommunication equipment against lightning

and transient induced by AC power lines. The

package / die size ratio has been optimized by

using the SMA package.
