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
