BT137S-600G,118

Triacs Overview

The BT137S-600G,118 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a DPAK (TO-252) surface-mount package designed for general-purpose bidirectional switching and phase control applications. The device features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage of 600 V. Key electrical parameters include a maximum holding current of 20 mA, a non-repetitive peak on-state current of 71 A, and a maximum junction temperature of 125 °C. The component operates within a temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Sensitive gate architecture allows direct interfacing with microcontrollers and logic circuits.
• Planar passivation technology ensures high voltage ruggedness and long-term reliability.
• Four-quadrant triggering capability provides flexibility in gate signal application.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation to confirm pinout and thermal characteristics, as variations exist within the BT137S series. Ensure the ordering code matches the exact tape-and-reel configuration required for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status.

Triacs Selection Notes

Select this component when a surface-mount solution is required for AC power control circuits. The 8 A current rating suits moderate load applications. Verify that the PCB footprint accommodates the TO-252 package dimensions. Consider the thermal resistance of the board layout, as the small form factor requires adequate copper area for heat dissipation during continuous operation.

Triacs Part Context

This part belongs to the BT137S series of glass or planar passivated triacs from WeEn Semiconductors. The series is widely used in consumer electronics and industrial controls where compact size and reliable switching are critical. The SMD variant offers advantages in automated manufacturing compared to through-hole equivalents like the BT137-600E.

Triacs Replacement Considerations

Direct replacements include the BT137S-600,118 and BT137S-600F. Verify compatibility with existing footprints and ensure that gate trigger currents remain within the driving circuit's capabilities. Check for any differences in thermal performance between plastic and glass passivated variants if operating near maximum ratings.
