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: IR = 2 µA max.
Holding current: IH = 150 mA min.
Repetitive peak pulse current:
IPP = 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.
