SMP75 Datasheet, PDF (1/9 Pages) STMicroelectronics – Trisil™ for telecom equipment protection

SMP75
Trisil™ for telecom equipment protection
Features
■ bidirectional crowbar protection
■ voltage: 8 V
■ low leakage current: I_R = 2 µA max
■ holding current: I_H = 150 mA min
■ repetitive peak pulse current:
I_PP = 75 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 to
meet main standards such as UL1950,
IEC 950 / CSA C22.2 and UL1459.
■ Trisils have UL94 V0 approved resin.
■ SMB package is JEDEC registered
(DO-214AA).
■ Trisils comply with the following standards:
– GR-1089 Core
– ITU-T-K20/K21
– VDE0433
– VDE0878
– IEC 61000-4-5
– FCC part 68
Applications
Any sensitive equipment requiring protection
against lightning strikes and power crossing:
■ Ethernet,
■ T1/E1

Description
The SMP75 is a very low voltage transient surge
arrestor especially designed to protect sensitive
telecommunication equipment against lightning
strikes and other transients. Its low voltage makes
it suitable to protect low voltage transformer in
T1/E1 and Ethernet links without saturation of the
transformer.
