BT136X-600D,127

Overview

The BT136X-600D,127 is a four-quadrant sensitive gate Triac manufactured by WeEn Semiconductors. It features an RMS on-state current rating of 4 A and a non-repetitive peak on-state current of 27 A. The device supports a rated repetitive off-state voltage (VDRM) of 600 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include a gate trigger current (Igt) of 5 mA, a gate trigger voltage (Vgt) of 700 mV, and a holding current (Ih) of 10 mA. The on-state voltage is specified at 1.4 V. It operates within a temperature range of -40°C to +125°C and utilizes a TO-220FP-3 package.

Feature Summary

• Sensitive gate architecture designed for direct interfacing with microcontrollers, logic integrated circuits, and low-power gate trigger circuits.
• Four-quadrant triggering capability ensures reliable operation across all combinations of MT2 and gate polarities.
• Planar passivated construction provides enhanced voltage ruggedness and long-term reliability.

Applications

• General purpose bidirectional switching
• Phase control applications
• General purpose motor control

Selection Notes

Select this component when a 4 A RMS current capacity and 600 V blocking voltage are required in a through-hole isolated package. The sensitive gate specification allows for direct drive from low-power logic sources without additional amplification. Ensure the application environment remains within the -40°C to +125°C operating temperature range and that the load current does not exceed the 27 A non-repetitive surge limit.

Part Context

This part belongs to the BT136 series of four-quadrant Triacs produced by WeEn Semiconductors. The 'X' designation indicates the use of the SOT186A (TO-220F) isolated plastic package, which provides thermal isolation between the mounting base and the internal die. This series is engineered for general-purpose AC power control tasks requiring robust performance and compatibility with modern digital control interfaces.

Replacement Considerations

Compatible substitutes include the BT136-600D/DG,127 and other BT136 variants sharing identical 4 A/600 V ratings and sensitive gate characteristics. Verify that any replacement maintains the TO-220FP-3 footprint or compatible mechanical dimensions to ensure proper board integration.
