BTA312-600D,127

Triacs Overview

The BTA312-600D,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package designed for through-hole mounting. The device features a rated repetitive off-state voltage of 600 V and an on-state RMS current capability of 12 A. It supports a non-repetitive peak on-state current of 100 A and operates with a maximum junction temperature of +125 °C. Key electrical characteristics include a maximum gate trigger current of 5 mA across quadrants Q1, Q2, and Q3, and a dV/dt rating of 20 V/µs.

Triacs Feature Summary

• Planar passivated construction ensures robust performance and reliability under industrial conditions.
• High commutation capability balances switching performance with gate sensitivity requirements.
• Very sensitive gate design facilitates direct interfacing with low-power drivers and microcontrollers.

Triacs Applications

• Industrial motor control systems requiring reliable phase control
• Lighting applications utilizing low-power driver interfaces
• General-purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing method. The standard variant utilizes a TO-220AB package with horizontal rail pack distribution. Confirm RoHS compliance and lead-free status against the latest manufacturer documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current are required in a through-hole format. The very sensitive gate characteristic makes it suitable for designs driven by low-current logic outputs. Ensure the application environment remains within the specified +125 °C maximum junction temperature limit.

Triacs Part Context

This part belongs to the BTA312 series of three-quadrant triacs from WeEn Semiconductors. It serves as a successor or alternative to previous generations like the BTA212 series, offering optimized commutation performance. The device is distinct from surface-mount variants such as the BTA312B, which utilizes a D2PAK package.

Triacs Replacement Considerations

The BTA212-600D,127 is a related predecessor in the same voltage and current class but may exhibit different gate sensitivity and commutation characteristics. Verify compatibility with existing drive circuits when substituting between these series.
