SMP75-8 STMicroelectronics

SMP75 Trisil for telecom equipment protection Features bidirectional crowbar protection voltage: 8 V low leakage current: I = 2 A max R holding current: I = 150 mA min H repetitive peak pulse current: I = 75 A (10/1000 s) PP SMB (JEDEC DO-214AA) Benefits Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. Figure 1. Device configuration 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 Description VDE0878 IEC 61000-4-5 The SMP75 is a very low voltage transient surge arrestor especially designed to protect sensitive FCC part 68 telecommunication equipment against lightning strikes and other transients. Its low voltage makes Applications it suitable to protect low voltage transformer in T1/E1 and Ethernet links without saturation of the Any sensitive equipment requiring protection transformer. against lightning strikes and power crossing: Ethernet, T1/E1 TM: Trisil is a trademark of STMicroelectronics.
