STMicroelectronics BTB08-800TARG Triac

The BTB08-800TARG is a high-performance triac manufactured by STMicroelectronics, designed to cater to a wide range of AC power control applications. This triac is part of the STMicroelectronics' Snubberless™ series, which is well-known for its high commutation performances. The device is capable of handling applications that require high bidirectional transient and blocking voltage capability and on-state current up to 8A.

With a maximum operating voltage of 800V, the BTB08-800TARG is suitable for use in various applications such as motor control circuits, small home appliances, lighting systems, and other devices where power AC load control is needed. The high voltage capability ensures that the triac can comfortably handle the surges often found in these applications, providing a reliable and robust solution for power control.

The BTB08-800TARG boasts a gate trigger voltage (Vgt) of typically 1.3V, which means it can be easily triggered with low power gate drive circuits, making it compatible with microcontroller outputs and other low-power control interfaces. Its gate trigger current (Igt) is also quite low, typically around 50mA, which further simplifies the design of the gate drive circuitry.

This triac features a TO-220AB insulated package, which provides good thermal performance and simplifies the heatsinking process. The insulation of the package allows for easy mounting on a heatsink without the need for additional insulation, which can save on manufacturing costs and simplify assembly.

For safety and reliability, the BTB08-800TARG is equipped with a high commutation capability, which allows it to handle the abrupt changes in load current that can occur in inductive loads without the need for additional snubber circuits. This feature makes the triac particularly suitable for applications with inductive loads, such as motor speed controllers or dimmer circuits.

In summary, the BTB08-800TARG from STMicroelectronics is a versatile and reliable triac that offers high voltage and current handling capability, low gate trigger characteristics, and robust performance in a wide range of AC power control applications. Its Snubberless™ technology and insulated package design make it an excellent choice for designers looking for a cost-effective and efficient solution for controlling power in AC circuits.
