STMicroelectronics SSRP105B1
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. The SSRP105B1 device takes into account this fact and is based on asymmetrical voltage characteristics (figure 3a).| Part No. | SSRP105B1 |
