SMP30
Trisil™ for telecom equipment protection
Features
■ Bidirectional crowbar protection
■ Voltage range from 62 V to 270 V
■ Low capacitance from 10 pF
to 20 pF typ.@ 50 V
■ Low leakage current: I
R
= 2 µA max.
■ Holding current: I
H
= 150 mA min.
■ Repetitive peak pulse current:
I
PP
= 30 A (10/1000 µs)
Benefits
■ Trisils are not subject to ageing and provide a
fail safe mode in short circuit for a better
protection.
■ This device can be used to help equipment
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).
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 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.
