BT136-600,127

Overview

The BT136-600,127 is a four-quadrant sensitive gate triac manufactured by WeEn Semiconductors. It features a rated repetitive peak off-state voltage of 600 V and an on-state RMS current of 4 A. The device supports a non-repetitive surge current of 27 A and operates within a junction temperature range of -40°C to +125°C. Packaged in a TO-220AB-3 through-hole housing, it exhibits a maximum holding current of 10 mA and a typical gate trigger voltage of 700 mV with a maximum gate trigger current of 5 mA. The component complies with RoHS standards.

Feature Summary

• Sensitive gate architecture enabling direct interface with microcontrollers and logic circuits
• Four-quadrant triggering capability for reliable switching across all gate polarities
• High thermal stability supporting operation up to 125°C junction temperature

Applications

• Lighting dimmer controls
• Solid state relays
• Motor speed control systems
• General purpose AC power switching

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and package variations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to integration. Ensure thermal management design accounts for the specified junction temperature limits during high-current operation.

Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current rating are required for AC load control. The sensitive gate characteristic makes it suitable for low-power drive applications. Verify that the TO-220AB-3 package fits the available board space and heatsinking constraints compared to surface mount alternatives like the BT136S series.

Part Context

This part belongs to the BT136 family of triacs, widely used for general-purpose AC switching. The '600' designation indicates the 600 V voltage class, while the ',127' suffix typically denotes the specific tape-and-reel or tube packaging configuration defined by WeEn Semiconductors. It serves as a standard replacement for legacy NXP/Philips designs.

Replacement Considerations

Direct pin-compatible substitutes include the BT136-600D,127 and BT136-600E,127 from WeEn Semiconductors. Cross-manufacturer equivalents such as STMicroelectronics BTA16 or BTA12 series may require verification of gate trigger current specifications to ensure compatibility with existing drive circuitry.
