BT137S-600D,118

Triacs Overview

The BT137S-600D,118 is a surface-mount bidirectional triac manufactured by WeEn Semiconductors. It features an 8 A RMS on-state current and a 600 V repetitive peak off-state voltage. The device utilizes a TO-252 (DPAK) package with three pins. Key electrical parameters include a maximum gate trigger current of 70 mA and a maximum holding current of 20 mA. It operates within a temperature range of -40°C to +125°C and supports a surge current rating of 71 A.

Triacs Feature Summary

• Sensitive gate design for direct microcontroller interfacing
• Glass passivated planar structure for reliability
• Four-quadrant triggering capability

Triacs Applications

• General purpose bidirectional switching
• Phase control applications
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix '118' against official WeSem documentation to confirm tape and reel specifications. Ensure the TO-252 package variant matches the required PCB footprint. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement orders.

Triacs Selection Notes

Select this component when a surface-mount solution is required for AC load control. The 600 V rating suits standard mains voltage applications. Compare gate sensitivity requirements against the 70 mA maximum trigger current to ensure compatibility with the driving circuitry. Verify thermal management needs given the 8 A continuous current capacity in the DPAK package.

Triacs Part Context

This part belongs to the BT137 series of sensitive gate triacs from WeEn Semiconductors. The series includes various packages such as TO-220 and TO-252. The BT137S variant specifically denotes the surface-mount configuration. These devices are designed for general-purpose AC switching and phase control tasks in consumer and industrial electronics.

Triacs Replacement Considerations

Compatible substitutes include the BT137S-600F and other BT137S-600 variants from WeEn or NXP. Verify pinout compatibility and electrical ratings match exactly. Alternative packages like BT137X-600 require different mounting considerations.
