SMP30
TRISIL™ FOR TELECOM EQUIPMENT PROTECTION
FEATURES
■ Bidirectional crowbar protection
■ Voltage range from 62V to 270V
■ Low capacitance from 10pF to 20pF typ.@ 50V
■ Low leakage current: I_R = 2µA max.
■ Holding current: I_H = 150 mA min.
■ Repetitive peak pulse current:
I_PP = 30 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 SMP30-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.
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 package is JEDEC registered (DO-214AC).
Trisils are UL497B approved (file: E136224).
