This document introduces the technical parameters and characteristics of BTA12 B/C BTB12 B/C triacs, including maximum operating temperature, maximum current, insulation voltage, etc.
The BTA12 B/C and BTB12 B/C are high‑surge‑current, glass‑passivated PNPN triacs suitable for general‑purpose phase‑control and static‑switching applications on inductive or resistive loads. They offer a 2500 V insulating voltage and are UL‑recognized (E81734).
The document provides absolute ratings, thermal resistances, gate and electrical characteristics, ordering information, and mechanical dimensions, along with recommended mounting torque and weight. All data are presented for both insulated (BTA) and uninsulated (BTB) variants.
| Repetitive peak off‑state voltage (VDRM) | 400 V – 800 V |
