BT137-600-0Q

Overview

The BT137-600-0Q is a four-quadrant triac manufactured by WeEn Semiconductors, designed for general-purpose bidirectional switching and phase control applications. It features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage of 600 V. The device 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 and a maximum holding current of 20 mA. The component is housed in a TO-220 package with three pins, suitable for through-hole mounting.

Feature Summary

• Four-quadrant triggering capability for versatile gate drive compatibility
• Planar passivated construction ensuring voltage ruggedness and reliability
• Sensitive gate design allowing direct interfacing with low-power logic circuits

Applications

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

Procurement Notes

Verify the specific suffix '0Q' against official WeSem datasheets to confirm pinout and mechanical dimensions match the standard TO-220AB form factor. Ensure the ordering part number aligns with the manufacturer's current naming convention, as suffixes may indicate packaging or specific manufacturing lot variations rather than functional differences.

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 interfaces with microcontrollers or logic ICs that provide limited gate drive current. Verify thermal management requirements for the TO-220 package based on the expected RMS current and ambient operating conditions.

Part Context

This part belongs to the BT137 series of four-quadrant triacs from WeEn Semiconductors. The series is characterized by planar passivation technology for enhanced reliability. Variants within the series typically differ by voltage ratings (e.g., 600V, 800V) and package types (TO-220, DPAK), sharing similar core electrical characteristics for phase control duties.

Replacement Considerations

Direct substitutes include other 8 A, 600 V four-quadrant triacs in TO-220 packages such as the BT136-600E or equivalent parts from other manufacturers offering sensitive gate functionality. Verify that replacement devices meet the same holding current and gate trigger specifications to ensure circuit stability.
