Overview
The BT137-600G0Q is a four-quadrant triac manufactured by WeEn Semiconductors, housed in a TO-220FP (SOT78) package. It features an RMS on-state current of 8 A and a repetitive peak off-state voltage of 600 V. The device supports a non-repetitive peak on-state current of 71 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger voltage of 1.5 V, a maximum holding current of 40 mA, and a peak on-state voltage of 1.65 V.
Feature Summary
- Four-quadrant sensitivity enables reliable triggering across all gate polarities and main terminal voltages.
- Planar passivated construction provides enhanced voltage ruggedness and long-term reliability.
- Sensitive gate architecture allows direct interfacing with microcontrollers and low-power logic circuits.
Applications
- General purpose bidirectional switching
- Phase control applications
- Motor drive and control systems
Procurement Notes
Verify the specific suffix 'G0Q' against official manufacturer documentation to confirm pinout and packaging variations. Ensure compatibility with existing thermal management designs given the TO-220FP form factor. Cross-reference datasheet revisions to confirm parameter stability before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring robust phase control with sensitive gate drive capabilities. The 8 A RMS rating suits moderate power loads, while the 600 V blocking voltage handles standard line voltages. Evaluate thermal dissipation requirements carefully, as the TO-220FP package offers improved heat transfer compared to standard plastic packages.
Part Context
This part belongs to the BT137 series of four-quadrant triacs from WeEn Semiconductors. The series is designed for general-purpose AC switching and phase control. Variants within the family differ primarily in voltage ratings, current capacities, and package types, but share common planar passivated technology and sensitive gate characteristics for ease of integration.
Replacement Considerations
Compatible substitutes include the BT137-600E and BT137-600/DG,127. Verify that replacement parts match the TO-220FP footprint and maintain equivalent 8 A RMS and 600 V ratings. Confirm gate trigger characteristics align with the existing control circuit design to ensure proper operation.
