BT136-600D/DG,127

Overview

The BT136-600D/DG,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 peak off-state voltage (VDRM) of 600 V with a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include a maximum holding current (Ih) of 10 mA, a gate trigger voltage (Vgt) of 700 mV, and a gate trigger current (Igt) of 5 mA. The component operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB-3 through-hole package.

Feature Summary

• Four-quadrant sensitive gate configuration for reliable triggering across all gate polarities
• High thermal stability supporting operation up to 125°C junction temperature
• Low gate sensitivity requiring minimal drive current for turn-on

Applications

• Lighting control systems including dimmers and ballasts
• General-purpose AC power switching applications
• Solid-state relays and motor speed control circuits

Procurement Notes

Verify the specific suffix DG against the manufacturer's official datasheet to confirm pinout orientation and mechanical dimensions. Ensure the ordering part number matches the exact electrical grade required for the design. Cross-reference the manufacturer code with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a 4 A RMS current capacity and 600 V blocking voltage are required in a through-hole format. The sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Verify that the TO-220AB-3 package fits the available PCB real estate and thermal management constraints of the target application.

Part Context
