BTA24-600BW

Triacs Overview

The BTA24-600BW is a 25 A RMS Snubberless Triac from STMicroelectronics, rated for 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40 °C to +125 °C and features a TO-220AB through-hole package. Key electrical parameters include a maximum holding current of 75 mA, a gate trigger current of 50 mA, and a non-repetitive surge current rating of 260 A. The device exhibits a typical on-state voltage of 1.55 V and supports high commutation capabilities across three or four quadrants.

Triacs Feature Summary

• Snubberless design enables direct switching of inductive loads without external RC snubber networks
• High thermal efficiency achieved through clip bonding technology and low thermal resistance construction
• Robust commutation performance supporting reliable operation in both three-quadrant and four-quadrant modes

Triacs Applications

• General purpose mains power AC switching circuits
• Solid state relays (SSRs) requiring high current handling
• Industrial motor control systems for AC load management

Triacs Procurement Notes

Verify the specific suffix against official documentation, as variations such as 'B' or 'C' may indicate differences in gate trigger characteristics. Confirm RoHS compliance status and UL certification file references directly with the manufacturer before finalizing component selection for regulated applications.

Triacs Selection Notes

Select this component for applications requiring 25 A continuous current handling at 600 V blocking voltage. Ensure the driving circuit can supply the specified 50 mA gate trigger current. Consider the TO-220AB package dimensions for adequate heatsinking to maintain junction temperatures below the 125 °C maximum limit during sustained operation.

Triacs Part Context

This part belongs to the BTA24 series of 25 A Snubberless Triacs manufactured by STMicroelectronics. The series includes variants with different voltage ratings, such as the BTA24-800BWRG, which shares similar current and thermal characteristics but offers higher voltage blocking capability for more demanding line voltage applications.

Triacs Replacement Considerations

Direct replacements within the same family include the BTB24-600BWRG, which utilizes a surface-mount D2PAK package instead of the through-hole TO-220AB form factor. Other compatible options include the BTA25-600BW, though availability status should be verified as it may be marked as Not Recommended for New Designs.
