This document describes the features and characteristics of the BTA/BTB04 T/D/S/A triac family, including very low IGT and IH, suitable for general purpose applications where gate high sensitivity is required, and suitable for 4Q applications such as phase control and static switching.
The BTA04 and BTB04 T/D/S/A triac family are high‑performance glass‑passivated PNPN devices with very low gate trigger current, suitable for general‑purpose applications such as phase‑control and static switching. The document provides absolute ratings, thermal resistance values, electrical characteristics and ordering information.
Key data include an insulating voltage of 2500 V RMS, on‑state RMS current of 4 A, non‑repetitive surge peak current of up to 42 A, and detailed mechanical dimensions for the TO‑220AB plastic package.
| Insulating voltage | 2500 V RMS |
|---|---|
| Junction‑to‑ambient thermal resistance | 60 °C/W |
| Junction‑to‑case thermal resistance (DC, BTA) | 44 °C/W |
| Package type | TO‑220AB (plastic) |
| Recommended mounting torque | 0.8 m·N |
The devices are rated for an insulating voltage of 2500 V RMS.
The recommended mounting torque is 0.8 m·N (maximum 1 m·N).
Both devices are supplied in a TO‑220AB plastic package.
