BT136-800E,127

Overview

The BT136-800E,127 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It features a planar passivated structure housed in an isolated TO-220FP-3 (SOT186A) package. The device supports a repetitive peak off-state voltage of 800 V and an RMS on-state current of 4 A. Non-repetitive peak on-state current reaches 25 A. Static characteristics include a maximum holding current of 15 mA and a gate trigger current up to 25 mA depending on the quadrant. The component operates within a temperature range of -40 °C to +125 °C.

Feature Summary

• Sensitive gate architecture enables direct interfacing with microcontrollers and low-power logic ICs.
• Planar passivated construction provides enhanced voltage ruggedness and long-term reliability.
• Four-quadrant triggering capability ensures reliable switching across all gate and main terminal polarities.
• Isolated mounting base facilitates secure thermal management without electrical shorting risks.

Applications

• General purpose motor control systems
• Bidirectional phase control circuits
• Resistive load switching applications

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configuration. Confirm RoHS compliance status through the latest datasheet revision. Check for any product change notifications that may affect pinout or material composition before finalizing procurement orders.

Selection Notes

Select this component when high blocking voltage and sensitive gate drive compatibility are required. Ensure the circuit design accommodates the specified 4 A RMS current rating under expected thermal conditions. Verify that the gate driver can supply sufficient current for all four triggering quadrants to guarantee robust turn-on performance.

Part Context

This part belongs to the BT136X series of sensitive gate triacs from WeEn Semiconductors. The series is designed for general-purpose AC power switching where direct logic interface is necessary. The TO-220FP-3 package offers a balance of current handling capacity and thermal dissipation for industrial and consumer electronics applications.

Replacement Considerations

Cross-reference with other 800 V, 4 A sensitive gate triacs in the TO-220FP-3 package. Verify that substitute devices match the four-quadrant triggering sensitivity and holding current specifications to ensure circuit stability without modification.
