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.

FEATURES

■ Dual bi-directional asymmetrical protection

Stand-off voltages:

● Between Line and Ground

+105V for positive voltages

-180V for negative voltages

● Between Line and Line

+180V for positive voltages

-180V for negative voltages

■ Peak pulse current: IPP = 50A (5/310µs)

■ Holding current:

● IH+ = 100mA

● IH- = 150mA

MAIN APPLICATIONS

Where asymmetrical protection against lightning

strikes and other transient overvoltages is required :

■ Solid-State relays

■ SLIC with integrated ring generator

SSRP105B1RL属于电路保护 > TVS - 晶闸管。意法半导体（ST）集团制造生产的SSRP105B1RLTVS - 晶闸管基于晶闸管的瞬态电压抑制 (TVS) 器件可用于提供过压保护，在正常工作条件下近似于开路。在这些器件两端施加超过某个特定值的电压（称为击穿电压），可使它们进入近似于短路的导通状态。?这种状态一直持续至流过器件的电流因电路中的一些外部影响而降低到称为“保持电流”的最小值以下。
