BCR5AM-12 is a thyristor switch element produced by Powerex, with an rated voltage of 400-600V and a rated current of 5A. It is suitable for AC switch, heating, motor control and lighting applications.
This document describes the Powerex BCR5AM triac, a solid‑state silicon AC switch suitable for inductive loads, lighting, motor control and heating applications. It lists physical dimensions, absolute maximum ratings and key electrical parameters such as off‑state voltage, on‑state current and gate characteristics.
Detailed tables give thermal resistance, storage and operating temperature ranges, transient thermal impedance curves, and performance graphs for various operating conditions. The data enable designers to select the part and design appropriate heat‑sinking and protection circuits.
