The BT137S-800E is a high-performance, sensitive gate Triac manufactured by NXP Semiconductors, designed for use in applications requiring direct interfacing to microcontrollers, logic integrated circuits, and other low power gate trigger circuits. This device is particularly well-suited for AC switching and phase control applications such as fan speed and temperature modulation, lighting controls, and static switching relays.
Key Features
- Blocking Voltage: The BT137S-800E boasts a maximum repetitive peak off-state voltage (VDRM) of 800V, making it suitable for operations in a wide range of mains voltages.
- On-state Current: With an RMS on-state current (IT(RMS)) of 8A, it can handle significant power, suitable for controlling moderately high loads.
- Gate Sensitivity: The device features a sensitive gate that requires only a small gate current to trigger, facilitating direct interfacing with digital circuits without the need for additional amplification.
- High Surge Current Capability: It has a non-repetitive peak on-state surge current (ITSM) of up to 80A, which allows it to handle high inrush currents typical in AC loads.
- Package: The BT137S-800E comes in a D2PAK surface-mount package, which is ideal for compact designs and automated PCB assembly processes.
