BT137-600E/DG

Overview

The BT137-600E/DG is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It operates with an RMS on-state current of 8 A and supports a non-repetitive peak on-state current of 71 A. The device features a rated repetitive off-state voltage (VDRM) of 600 V, with a maximum off-state leakage current of 100 uA at VDRM. The on-state voltage is specified at 1.3 V. Gate triggering requires a maximum holding current (Ih) of 20 mA, a gate trigger voltage (Vgt) of 700 mV, and a gate trigger current (Igt) of 11 mA. Designed for through-hole mounting in a TO-220AB-3 package, it functions within a maximum operating temperature range of +125 C.

Feature Summary

• Sensitive gate architecture designed for direct interfacing with microcontrollers, logic integrated circuits, and low-power gate trigger circuits.
• Four-quadrant sensitivity ensures reliable triggering across all combinations of main terminal voltage polarity and gate signal polarity.
• Planar passivation technology provides enhanced protection against mechanical stress and environmental factors.

Applications

• General purpose bidirectional switching applications
• Phase control circuits for AC power regulation
• Lighting dimmer controls

Procurement Notes

Verify the specific suffix DG against official WeEn Semiconductors documentation to confirm pinout configuration and packaging details. Ensure compatibility with the target thermal management requirements given the TO-220AB-3 through-hole form factor. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required for AC load control. The sensitive gate characteristic makes it suitable for driving from low-power digital logic or microcontroller outputs without additional amplification. Verify that the TO-220AB-3 package fits the available PCB space and heatsinking constraints for the intended application environment.

Part Context

This triac belongs to the BT137 series E family, which focuses on sensitive gate technologies for easy interface with modern digital control systems. The BT137-600E variant specifically denotes the 600 V voltage class within this series. The DG suffix indicates a specific manufacturing or packaging variation defined by WeEn Semiconductors, distinct from standard tape-and-reel or other tube configurations found in the broader BT137 lineup.

Replacement Considerations

Publicly confirmed substitute part numbers for the BT137-600E/DG are not available in the provided source data. Consult official replacement guides for equivalent sensitive gate triacs with matching 8 A/600 V specifications if direct substitution is required.
