BTA/BTB04 T/D/S/A is a high performance glass passivated PNPN device with low IGT and IH thresholds, suitable for general purpose applications where high gate sensitivity is required, such as four-quadrant 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 lists absolute ratings, thermal resistance values, gate and electrical characteristics, and ordering information.
Key information includes an insulating voltage of 2500 V RMS, a maximum RMS on‑state current of 4 A, detailed thermal resistance data, mechanical dimensions for the TO‑220AB package, and recommended mounting torque values. The datasheet also provides graphs of power dissipation versus temperature and on‑state current versus case temperature.
