P2703AB Description

Short technical summary and product information.

The Littelfuse P2703AB is a SIDACtor balanced series protection thyristor designed for overvoltage transient protection in baseband equipment. It features a patented Y-configuration that provides balanced overvoltage protection, preventing longitudinal to differential conversion.

 

Key electrical characteristics include an off-state voltage (V_DRM) of 230V to 300V at 5µA, a breakover voltage (V_BO) of 270V to 350V at 100V/µs, a holding current (I_H) of 150mA minimum, and a maximum switching current (I_S) of 800mA. The on-state current (I_T) is rated at 2.2A maximum with an on-state voltage (V_T) of 8V maximum at 2.2A. The device can handle peak surge currents up to 80A.

 

The P2703AB is housed in a 3-SIP TO-220 modified through-hole package, suitable for single-port protection applications. It is RoHS3 compliant and lead-free (Pb-free E3).
