This document describes the features and characteristics of the BTA08, BTB08, and T8 series triacs. They are suitable for general purpose AC switching and can be used in applications such as static relays, heating regulation, and induction motor starting circuits. The series offers high voltage, high temperature, and high surge current capabilities, making them suitable for use in high voltage and high temperature environments.
This document is a datasheet for the STMicroelectronics BTA08, BTB08, and T8 series of 8 A Triacs. It covers snubberless, logic level, and standard variants suitable for general purpose AC switching, static relays, heating regulation, and phase control applications. The snubberless versions are specifically recommended for inductive loads due to their high commutation performances. This manual is written in Chinese.
| On-state rms current | 8 A |
|---|---|
| Repetitive peak off-state voltage | 600 to 800 V |
| Triggering gate current (Logic Level) | 5 to 50 mA |
| Junction to case thermal resistance (TO-220AB) | 1.6 °C/W |
They are suitable for general purpose AC switching, static relays, heating regulation, induction motor starting circuits, light dimmers, and motor speed controllers.
The snubberless versions (BTA/BTB...W and T8 series) are specially recommended for use on inductive loads.
Yes, the logic level versions are designed to interface directly with low power drivers such as microcontrollers.
