SMP50 Datasheet - STMicroelectronics

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.

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
