Active995 in stock

Overview

The BTA204S-800E is a 3-quadrant logic-level TRIAC designed for direct interfacing with low-power microcontrollers and digital logic ICs. It supports a high blocking voltage of 800V and an RMS on-state current of 4A, making it suitable for AC switching in compact surface-mount designs.

Why Choose This Part

This TRIAC utilizes 3Q technology to provide improved noise immunity and high commutation capability without the need for a snubber circuit in many applications. Its sensitive gate (10mA max) allows for direct triggering from 5V or 3.3V logic, simplifying the drive circuitry and reducing component count.

Applications

Home Appliances
Controlling low-power AC loads such as washing machine valves, fans, and small kitchen appliances.
AC Solenoid Driving
Reliable switching of inductive solenoid loads in industrial automation and irrigation systems.
General Purpose Motor Control
Speed control and switching for small universal motors and shaded-pole motors.
Lighting Dimmers
Implementing phase-cut dimming for residential LED or incandescent lighting systems.

Getting Started

When designing with this DPAK component, ensure adequate PCB copper pour for thermal dissipation, as the tab is the primary heat path. Use a series gate resistor to limit current from your MCU and consider an opto-triac if galvanic isolation is required between the high-voltage AC and the control logic.
