BTB24-800BWRG

Triacs Overview

The BTB24-800BWRG is a Snubberless TRIAC from STMicroelectronics, rated for 25 A RMS on-state current and 800 V repetitive peak off-state voltage. It features a maximum gate trigger current of 50 mA and a gate trigger voltage of 1.3 V. The device supports a non-repetitive surge current of 260 A and has a maximum holding current of 75 mA. Operating within a junction temperature range of -40°C to +125°C, it utilizes a TO-220-3 through-hole package with an insulated tab.

Triacs Feature Summary

• Snubberless design enables direct switching of inductive loads without external RC snubber circuits
• Insulated tab construction provides electrical isolation between the terminal and heatsink mounting surface
• High commutation capability allows reliable operation across multiple quadrants

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'WRG' against the manufacturer datasheet to confirm RoHS compliance and lead-free status. Ensure the TO-220-3 insulated package variant matches the thermal management requirements of the target application. Cross-reference the part number with official STMicroelectronics documentation to validate availability and manufacturing origin.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 800 V blocking voltage are required for mains-powered applications. The insulated tab feature is critical for designs where the heatsink must remain electrically isolated from the circuit ground. Verify that the 50 mA gate trigger current aligns with the driving circuit's output capabilities.

Triacs Part Context

This device belongs to the BTA24/BTB24 series of high-current TRIACs designed for industrial and consumer AC power control. The BTB24 variant specifically denotes the surface-mount or specialized through-hole insulated configuration within the broader family of Snubberless TRIACs offered by STMicroelectronics.

Triacs Replacement Considerations

The BTA24-800BWRG shares identical electrical ratings but typically lacks the insulated tab found in the BTB24 variant. Substitution requires verifying that the mechanical mounting and thermal interface can accommodate the difference in insulation properties.
