BTA26-400BRG

Triacs Overview

The BTA26-400BRG is a three-terminal TRIAC from STMicroelectronics, rated for 400 V repetitive peak off-state voltage and 25 A RMS on-state current. It utilizes a TOP-3 through-hole package with an internal ceramic insulating pad providing 2500 V RMS isolation. Key electrical parameters include a maximum on-state voltage of 1.55 V, a non-repetitive surge current rating of 260 A, and a maximum holding current of 80 mA. The device operates within a junction temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Features high commutation capability suitable for general-purpose AC switching applications
• Incorporates an internal ceramic insulating pad for enhanced voltage isolation
• Designed with low thermal resistance and clip bonding for efficient heat dissipation

Triacs Applications

• General purpose mains power AC switching
• Static switching on inductive or resistive loads
• Phase control circuits

Triacs Procurement Notes

Verify the specific suffix 'RG' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected component matches the required 400 V blocking voltage for the target circuit design.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 400 V blocking voltage are required for AC load control. Consider the TOP-3 package dimensions and through-hole mounting requirements during PCB layout planning.

Triacs Part Context

This part belongs to the BTA26 series of standard TRIACs manufactured by STMicroelectronics. The series is designed for robust performance in high-current applications, offering reliable switching capabilities for industrial and consumer electronics.

Triacs Replacement Considerations

Compatible substitutes include other BTA26 variants with matching voltage ratings, such as BTA26-600B or BTA26-800B, provided the higher voltage ratings do not impact cost or availability constraints.
