STMicroelectronics Triac, 600V 4A, TO-252, 5mA 1.3V, 500mW

The STMicroelectronics Triac is a versatile 4-quadrant sensitive gate component, engineered for reliable performance in general-purpose applications that demand robust surge current capability. Its design allows for direct drive from microcontrollers (MCUs), simplifying circuit design and integration. This triac is an excellent choice for controlling inductive and resistive loads in various domestic and industrial settings.

Constructed in a compact TO-252 (DPAK) surface-mount package, it offers a space-efficient solution for modern PCB designs. With a peak repetitive off-state voltage of 600V and an on-state RMS current rating of 4A, it provides a solid foundation for building durable power control circuits. Its low gate trigger voltage requirement of a maximum 1.3V ensures compatibility with low-voltage logic signals.

Key Applications

This triac is particularly well-suited for:

• Motor Control Circuits: Provides smooth switching for small AC motors.
• Small Home Appliances: Ideal for controlling heating elements, lights, or motors in appliances like food processors, coffee makers, or power tools.
• Fan Speed Controllers: Enables efficient and reliable speed regulation for AC fans.
