TELECOM EQUIPMENT PROTECTION: TRISIL™ |
|
|
FEATURES
■Bidirectional crowbar protection
■Voltage range from 62V to 270V
■Low capacitance from 15pF to 30pF typ.@ 50V
■Low leakage current: IR = 2µA 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
The SMP50-xxx 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.
BENEFITS
SMA
(JEDEC DO-214AC)
SCHEMATIC DIAGRAM
Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. Trisils 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 resin approved. SMA package is JEDEC registred. (Trisils are UL 497B approved - file: E136224).
