SSRP105B1 Datasheet (ST Microelectronics) - DUAL ASYMMETRICAL OVERVOLTAGE PROTECTION FOR TELECOM LINE

SSRP105B1, DUAL ASYMMETRICAL OVERVOLTAGE PROTECTION FOR TELECOM LINE

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.
