SMTPA130 - STMicroelectronics

SMTPA130 Trisil

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 .

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, .
