BTA10-400CRG

Triacs Overview

The BTA10-400CRG is a Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current (ItRMS) of 10 A and a repetitive peak off-state voltage (VDRM) of 400 V. The device utilizes a TO-220AB package with three pins for through-hole mounting. Key electrical parameters include a maximum gate trigger current (Igt) of 50 mA, a maximum gate trigger voltage (Vgt) of 1.3 V, and a maximum holding current (Ih) of 25 mA. The non-repetitive peak on-state current (surge current) is rated at 95 A. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Supports four-quadrant triggering for reliable operation across all phases of the AC cycle.
• Utilizes Snubberless technology to provide high commutation performance suitable for inductive loads.

Triacs Applications

• General-purpose AC power switching
• Static relay control
• Heating regulation systems

Triacs Procurement Notes

Verify the specific manufacturer datasheet for the BTA10-400CRG to confirm exact thermal resistance values and mechanical dimensions. Ensure that the selected heat sinking solution accommodates the TO-220AB package constraints and the specified maximum operating junction temperature limits under expected load conditions.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 400 V blocking voltage are required for AC load control. The TO-220AB package facilitates easy integration into through-hole designs. Consider the 50 mA gate trigger current requirement when designing the driving circuitry to ensure sufficient drive strength for reliable turn-on.

Triacs Part Context

This part belongs to the BTA series of Triacs from STMicroelectronics, which are widely used in household appliances and industrial controls. The BTA10 variant specifically targets applications requiring moderate current handling capabilities within a standard through-hole form factor, balancing performance with cost-effectiveness for general switching tasks.

Triacs Replacement Considerations

Direct replacements must match the 10 A ItRMS, 400 V VDRM, and TO-220AB package specifications. Verify compatibility regarding gate trigger characteristics and thermal management requirements before substitution.
