TELECOM EQUIPMENT PROTECTION: TRISILâ¢
FEATURES
s Bidirectional crowbar protection
s Voltage range from 62V to 270V
s Low capacitance from 15pF to 30pF typ.@ 50V
s Low leakage current: IR = 2µA max.
s Holding current: IH = 150 mA min.
s Repetitive peak pulse current:
IPP = 50 A (10/1000 µs)
MAIN APPLICATIONS
Telecommunication equipment such as
s Analog and digital line cards (xDSL, T1/E1,
ISDN...).
s Terminals (phone, fax, modem...) and central
office equipment.
SMA
(JEDEC DO-214AC)
SCHEMATIC DIAGRAM
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
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).
