BT136X-600,127

Overview

The BT136X-600,127 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in an isolated SOT186A (TO-220F) plastic package designed for general-purpose bidirectional switching and phase control applications. This component features a repetitive peak off-state voltage of 600 V and an RMS on-state current rating of 4 A. The device supports non-repetitive peak on-state currents up to 25 A and operates within a junction temperature range from -40 °C to +125 °C.

Feature Summary

• Sensitive gate architecture enables direct interfacing with microcontrollers, logic integrated circuits, and low-power gate trigger circuits without additional driver components.
• Planar passivation technology provides enhanced voltage ruggedness and long-term reliability under high-stress electrical conditions.
• Four-quadrant triggering capability ensures reliable activation across all combinations of main terminal and gate polarities.

Applications

• General purpose motor control systems
• General purpose bidirectional switching circuits
• Phase control applications requiring logic-level interface

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical characteristics and packaging specifications. Ensure that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to maintain quality standards and traceability throughout the supply chain.

Selection Notes

Select this component when a logic-level triac is required for direct microcontroller interfacing in AC power control circuits. The TO-220F package offers thermal isolation benefits suitable for mounting on heatsinks. Confirm that the 600V blocking voltage and 4A continuous current ratings align with the specific load requirements of the target application design.

Part Context

This part belongs to the BT136X series of sensitive gate triacs produced by WeEn Semiconductors. The 'X' designation typically indicates the use of the SOT186A (TO-220F) isolated package variant. The series is engineered for applications demanding robust performance and compatibility with modern digital control interfaces.

Replacement Considerations

Compatible substitutes include other logic-level triacs from the same family, such as the BT136-600D,127 or BT136-600E,127. Verify pinout compatibility and ensure that the alternative part meets the specific gate trigger current and holding current requirements of the existing circuit design.
