SMP75-8
TRISIL™ FOR TELECOM EQUIPMENT PROTECTION
FEATURES
■ Bidirectional crowbar protection
■ Voltage: 8V
■ Low leakage current : I_R = 2µA max
■ Holding current: I_H = 150 mA min
■ Repetitive peak pulse current :
I_PP = 75 A (10/1000µs)
MAIN APPLICATIONS
Any sensitive equipment requiring protection
against lightning strikes and power crossing:
■ Ethernet, T1/E1
DESCRIPTION
The SMP75-8 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, ethernet links without saturation of the trans-
former.
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 main
standards such as UL1950, IEC950 / CSA C22.2
and UL1459. They 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,
IEC61000-4-5 and FCC part 68.
