BTA41-600B IC TOP3 ST 40A 600V BTA41-600B

Product Overview

A high-power bidirectional triode thyristor (TRIAC) engineered for heavy-duty AC power switching, industrial phase control, and resistive or inductive load management. Capable of handling a massive continuous RMS on-state current of up to 41A and enduring a repetitive peak off-state voltage of 600V, this device is designed to safely handle high electrical stresses, supported by a high peak non-repetitive surge current rating of 400A. Housed in a robust, high-power TOP-3 package optimized for superior thermal dissipation, it operates reliably across a wide temperature spectrum from minus 40 to plus 125 degrees Celsius. It is ideal for heavy industrial motor speed regulators, high-wattage heating element controllers, solid-state relays, and electronic welding equipment.
