Overview
The BT137-600E,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 general-purpose bidirectional switching and phase control applications. The device features an RMS on-state current of 8A and a repetitive peak off-state voltage of 600V. Key electrical parameters include a maximum gate trigger voltage of 1.5V, a gate trigger current of 10mA, and a holding current of 20mA. It supports a non-repetitive peak on-state current of 65A and operates at a maximum junction temperature of 125°C.
Feature Summary
- Sensitive gate architecture enables direct interfacing with microcontrollers and low-power logic circuits.
- Planar passivation technology provides enhanced voltage ruggedness and long-term reliability.
- Four-quadrant triggering capability ensures reliable operation across all gate signal polarities.
Applications
- General purpose bidirectional switching
- Phase control applications
- Motor drive and control systems
Procurement Notes
Verify the specific ordering suffix to confirm the package type and reel/tube configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before integration into existing designs.
Selection Notes
Select this component when an 8A RMS current rating and 600V blocking voltage are required in a through-hole package. The sensitive gate characteristic makes it suitable for low-power driving circuits. Verify that the thermal management design accommodates the specified maximum junction temperature limits during continuous operation.
Part Context
This part belongs to the BT137 series E Triacs from WeEn Semiconductors. The series is characterized by its sensitive gate technology, allowing for efficient control with minimal gate drive power. The TO-220AB package offers robust mechanical stability and effective heat dissipation for medium-power industrial applications.
Replacement Considerations
Direct substitutes include the BT137-600E from NXP Semiconductors. Other compatible options within the same family include the BT137-600 and BT137X-600E, provided the package and electrical ratings match the original design requirements.
