Ween Semiconductors TO-220AB Triac 8A 600V 10mA

The Ween 8A 600V Triac is a planar passivated, very sensitive gate, four-quadrant semiconductor device engineered for general purpose bidirectional switching and phase control applications. It is housed in a TO-220AB (SOT78) plastic package and is designed as a 'Series D' triac for AC power control tasks.

Key Features

• Planar passivated construction, which enhances voltage ruggedness and long-term operational reliability
• Very sensitive gate with four-quadrant triggering, offering flexibility in circuit design
• Suitable for direct interfacing with microcontrollers, logic integrated circuits and other low-power gate trigger circuits
• Blocking voltage of 600V and on-state RMS current rating of 8A
• Maximum gate trigger voltage of 1V and maximum holding current of 10mA
• Peak non-repetitive surge current rating of 71A
• Maximum operating junction temperature of 125°C

Overview

The very low gate trigger voltage and holding current support efficient and reliable switching, particularly for low-current loads. Its ability to trigger in all four quadrants provides flexibility in circuit design, and the device is suited to applications where minimising electromagnetic interference (EMI) during commutation is critical.

Applications

• General purpose motor control for speed regulation and directional control of AC motors in appliances, power tools and industrial equipment
• AC switching of heaters, lamps and other resistive or inductive loads
• Phase control circuits, including light dimmers, fan speed controllers and universal motor controls
• Direct logic interface, driven from low-power drivers, logic ICs and microcontroller GPIO pins

Specifications

• Package: TO-220AB (SOT78) plastic
• Dimensions: Width 3.3, Depth 1.5, Height 4.3
• Weight: 31.751 gm

The Ween triac combines a 600V blocking voltage with an 8A on-state RMS current rating, making it a practical choice for AC power control tasks.
