BT137-600E Triac 600V 8A Through Hole TO-220

Description

BT137-600E Triac 600V 8A Through Hole TO-220 The BT137‑600E is a four‑quadrant, planar‑passivated sensitive‑gate triac designed for robust bidirectional AC switching. Housed in a standard TO‑220AB (SOT78) plastic package, it delivers a repetitive peak off‑state voltage rating of 600 V and a continuous RMS on‑state current capacity of up to 8 A. Its planar passivation enhances voltage ruggedness, ensuring consistent performance under demanding surge and switching conditions. Encased in a single‑ended, heatsink‑mountable TO‑220AB body with a mounting hole on the metal backplate, the BT137‑600E offers efficient thermal dissipation to the mounting base. The three‑lead configuration comprises Main Terminal 1 (T1), Main Terminal 2 (T2, also the mounting base), and Gate (G), arranged for straightforward PCB layout and mechanical stability. Epoxy molding around the planar silicon die provides insulation and environmental protection while maintaining a low profile suitable for through‑hole production lines. Equipped with a sensitive gate requiring only a few milliamps of trigger current, this device interfaces directly with microcontrollers, logic ICs, and other low‑power driver circuits. Its four‑quadrant triggering capability allows conduction initiation in all combinations of main terminal and gate polarities, facilitating flexible phase‑control applications and minimizing external driver complexity. The sensitive gate design also contributes to reduced EMI during commutation, making it a practical choice for both general‑purpose switching and motor‑control systems. Features: High blocking voltage capability. Direct triggering from low power drivers and logic ICs. Planar passivated for voltage ruggedness and reliability. Triggering in all four quadrants. Low holding current for low current loads and lowest EMI at commutation. Sensitive gate.
