BTA24-800BRG

Triacs Overview

The UMW BTA24-800BRG is a silicon bidirectional triac featuring an NPNPN five-layer structure and single-sided digging technology. It provides high blocking voltage and temperature stability in a TO-220A package. Key electrical parameters include an RMS on-state current of 24 A at Tc=80°C, a non-repetitive surge peak on-state current of 240 A (50Hz, 20ms), and an off-state repetitive peak voltage of 800 V. The device supports a maximum junction temperature of 125°C and operates within a storage range of -40 to +150°C. Gate trigger current is limited to 50 mA, with a peak gate current rating of 4 A.

Triacs Feature Summary

• Utilizes single-sided digging technology and table glass passivation for enhanced reliability.
• Features multi-layer metallized electrodes on the back for improved thermal performance.
• Offers high commutation capability suitable for general-purpose AC switching applications.

Triacs Applications

• Motor speed controllers for vacuum cleaners and power tools
• Solid state relays
• Heating controllers and temperature regulation circuits
• Phase control circuits

Triacs Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct package and voltage ratings. Confirm that the TO-220A form factor matches the target PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the end product assembly process.

Triacs Selection Notes

Select this component when a 24 A RMS current rating and 800 V blocking voltage are required for AC load switching. Ensure the application circuit can handle the specified 240 A surge current during turn-on events. Verify that the gate drive circuitry can supply the necessary 50 mA trigger current under all operating temperature conditions.

Triacs Part Context

This part belongs to the BTA24 series of Snubberless TRIACs designed for mains power AC switching. The series includes variants with different voltage ratings such as 600 V and 800 V options. These devices are engineered for industrial and consumer applications requiring robust high-current handling capabilities in standard through-hole packages.

Triacs Replacement Considerations

Direct substitutes may include other 25 A class TRIACs in TO-220 packages from manufacturers like STMicroelectronics or LRC. Verify that replacement parts match the 800 V rating and similar thermal resistance characteristics to maintain system performance integrity.
