SSRP105B1 Datasheet PDF - STMicroelectronics

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
