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). TM: TRISIL is a
