BTA24-600BWRG

Triacs Overview

The BTA24-600BWRG is a three-terminal TRIAC manufactured by STMicroelectronics, designed for general-purpose mains power AC switching applications. It operates within a repetitive peak off-state voltage range of 600 V and supports an RMS on-state current of 25 A. The device features a non-repetitive surge current rating of 260 A and maintains a low on-state voltage of 1.55 V. Gate triggering parameters include a maximum gate trigger current of 50 mA and a gate trigger voltage of 1.3 V. The component is housed in a TO-220-3 package with through-hole mounting, offering a thermal resistance optimized for clip bonding. It functions reliably across an operating temperature range from -40 °C to +125 °C.

Triacs Feature Summary

• Snubberless design capability allowing direct connection to capacitive loads without external RC snubber networks
• High commutation performance supporting reliable switching in both three-quadrant and four-quadrant modes
• Integrated internal ceramic pad providing electrical insulation between the terminal and the heatsink

Triacs Applications

• General purpose mains power AC switching circuits
• Solid state relays requiring high commutation stability
• Industrial motor control systems utilizing resistive or inductive loads

Triacs Procurement Notes

Verify the specific suffix 'B' against official STMicroelectronics documentation to confirm the exact voltage rating and gate characteristics. Ensure the procurement channel provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in thermal or electrical specifications during sourcing.

Triacs Selection Notes

Select this component when a 25 A RMS current capacity and 600 V blocking voltage are required for AC load control. The Snubberless feature makes it suitable for designs aiming to minimize passive components. Verify that the application environment stays within the specified -40 °C to +125 °C junction temperature limits and that the TO-220-3 package fits the mechanical constraints of the PCB layout.

Triacs Part Context

This device belongs to the BTA24 series of standard and Snubberless TRIACs from STMicroelectronics. The series is engineered for robust performance in industrial and consumer AC power applications. The BTA variant specifically denotes a through-hole insulated package configuration, distinguishing it from surface-mount alternatives like the BTB series while maintaining identical electrical performance profiles.

Triacs Replacement Considerations

The BTB24-600BWRG serves as a functional equivalent with identical electrical ratings but utilizes a surface-mount package instead of through-hole. Designers must account for the physical footprint differences when substituting these parts.
