BT136-600D,127

Overview

The BT136-600D,127 is a glass passivated triac manufactured by WeEn Semiconductors, housed in a TO-220AB-3 through-hole package. It features a rated repetitive peak off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 4 A. The device supports a non-repetitive surge current of 27 A with a maximum holding current (Ih) of 10 mA. Gate triggering specifications include a maximum DC gate trigger current (Igt) of 5 mA and a maximum gate trigger voltage (Vgt) of 700 mV. The component operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Sensitive gate architecture enabling reliable triggering from logic-level interfaces
• Glass passivation providing protection against moisture and mechanical stress
• High thermal stability suitable for demanding industrial environments

Applications

• Lighting control systems
• Solid-state relays
• Motor speed control circuits

Procurement Notes

Verify the manufacturer marking and date code upon receipt to confirm authenticity. Ensure the TO-220AB-3 package dimensions match the design footprint. Check for physical damage to the leads before soldering. Confirm RoHS compliance status if required by specific project regulations.

Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current rating are required in a standard through-hole configuration. The sensitive gate characteristic allows direct drive from low-power microcontrollers or logic gates without additional amplification stages.

Part Context

This part belongs to the BT136 series of four-quadrant logic level triacs originally developed by Philips Semiconductors. Following the establishment of the WeEn Semiconductors joint venture, production and documentation responsibilities transitioned to WeEn while maintaining the established electrical specifications and pinout compatibility.

Replacement Considerations

Compatible substitutes include the BT136-600E,127 variant which offers higher voltage ratings, and equivalent parts from other manufacturers such as STMicroelectronics BTA16 series or Littelfuse THYRISTOR series components with matching TO-220 packages.
