P3203ABL Description

Short technical summary and product information.

The Littelfuse P3203ABL is a SIDACtor balanced series protection thyristor designed for baseband equipment overvoltage protection. It features a repetitive peak off-state voltage (VDRM) range of 270V to 350V and a switching voltage (VS) of 270V to 350V at 100V/µs. The device offers a minimum holding current of 150mA and a maximum switching current of 800mA, with a maximum on-state current of 2.2A and an on-state voltage of 8V at 2.2A.

The P3203ABL provides low capacitance values of 45pF (pins 1-2, 3-2) and 70pF (pins 1-3), making it suitable for balanced overvoltage protection in voice and DS-1 applications. It is packaged in a through-hole 3-SIP with a modified TO-220 supplier device package, ensuring compatibility with standard PCB layouts.

This component is RoHS3 compliant and Pb-free, meeting environmental standards for lead-free manufacturing. The SIDACtor technology ensures fails short circuit when surged beyond ratings, providing reliable protection without degrading surge capability after multiple events.
