BT136X-600E/DG,127

Overview

The BT136X-600E/DG,127 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 4 A. The device supports non-repetitive peak on-state currents of 27 A. Key electrical parameters include a maximum holding current (Ih) of 15 mA, a gate trigger voltage (VGT) of 700 mV, and a gate trigger current (IGT) of 11 mA. The component operates within a temperature range of -40 °C to +125 °C and utilizes a TO-220F-3 (SOT186A) through-hole package.

Feature Summary

• Sensitive gate design enables direct interfacing with microcontrollers and low-power logic integrated circuits.
• Four-quadrant triggering capability ensures reliable operation across all gate and main terminal polarities.
• Isolated mounting base in the SOT186A plastic package provides thermal management and electrical isolation.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist between standard rail packaging and tape-and-reel formats. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the selected variant matches the required gate sensitivity and package isolation characteristics for the target circuit design.

Selection Notes

Select this component when a 600 V rating and 4 A continuous current capacity are required for AC load control. The sensitive gate characteristic makes it suitable for direct drive from digital logic without additional amplification. Consider the TO-220F-3 package for applications requiring isolated heat sinking and robust through-hole mounting.

Part Context

This part belongs to the BT136X series of planar passivated triacs designed for general-purpose use. The 'X' designation indicates the SOT186A (TO-220F) isolated package, while the 'E' suffix denotes the sensitive gate version optimized for low-power driver interfaces. It serves as a solid-state alternative to mechanical relays in AC power control systems.

Replacement Considerations

Compatible substitutes include the BT136X-600D,127 and BT136-600E/DG,127. Verify that replacement parts match the 600 V blocking voltage and 4 A current ratings. Check if the substitute's gate trigger current falls within the driving circuit's capabilities, particularly comparing the 11 mA requirement of the E-series against other variants.
