SSRP105B1 Datasheet Dual Asymmetrical Overvoltage Protection For Telecom Line

Manufacturer: STMicroelectronics

Overview: ® SSRP105B1 DUAL ASYMMETRICAL OVERVOLTAGE PROTECTION FOR TELE LINE Application Specific Discretes ASD™ MAIN APPLICATIONS Where asymmetrical protection against lightning strikes and other transient overvoltages is.

General Description

The SSRP105B1 is a dual asymmetrical transient voltage suppressor designed to protect a solid-state ring relay or SLICs with integrated ring generator from overvoltages.

The asymmetrical protection configuration is necessary to allow the use of all different types of ringing schemes.
