BT137-600/DG,127

Overview

The BT137-600/DG,127 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220AB (SOT78) plastic package designed for through-hole mounting. The device supports an RMS on-state current of 8 A and withstands a repetitive peak off-state voltage of 600 V. Key electrical parameters include a maximum gate trigger voltage of 1.5 V and a gate trigger current of 10 mA. The component operates within a temperature range of -40°C to +125°C and features a non-repetitive peak on-state current rating of 71 A.

Feature Summary

Sensitive gate architecture enabling reliable triggering with low gate drive power requirements.
Planar passivation technology providing enhanced voltage ruggedness and long-term reliability.
Four-quadrant switching capability allowing control in both positive and negative gate and MT1 polarity conditions.

Applications

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

Procurement Notes

Verify the complete part number including the suffix ,127 to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status via the manufacturer's latest documentation before integration. Cross-reference the specific datasheet revision to validate thermal characteristics and pinout definitions against the design requirements.

Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required for through-hole assemblies. The sensitive gate characteristic makes it suitable for direct interface with logic-level drivers or optocouplers without additional amplification. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range for optimal performance.

Part Context

This triac belongs to the BT137 series from WeEn Semiconductors, which includes variants such as BT137-600E and BT137X-600D. These devices share similar electrical profiles but differ in packaging styles and specific gate sensitivity ratings. The BT137-600/DG,127 specifically denotes the standard TO-220AB form factor intended for general industrial and consumer electronics markets.

Replacement Considerations

Direct substitutes include BT137-600E,127 and BT137-600/DG. Verify that replacement parts maintain compatible gate trigger currents and holding currents to ensure circuit stability without redesigning the drive network.
