BTA24-600CW

Triacs Overview

The BTA24-600CW is a 25 A RMS Snubberless Triac from STMicroelectronics, designed for general-purpose AC switching in through-hole TO-220 packages. It features a 600 V repetitive peak reverse voltage and supports a 260 A surge current. Key electrical parameters include a maximum gate trigger current of 35 mA, a holding current of 50 mA, and a peak on-state voltage of 1.55 V. The device operates within a junction temperature range of -40°C to 125°C and provides 2500 VRMS insulation via an internal ceramic pad.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Voltage insulated tab with 2500 VRMS isolation rating
• UL recognized component compliant with UL1557 standards

Triacs Applications

• Static relays and ON/OFF switching functions
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in light dimmers and motor speed controllers

Triacs Procurement Notes

Verify the specific suffix 'CWRG' or 'CW' against the required datasheet revision, as these denote package and compliance variations. Confirm that the TO-220 through-hole form factor matches the target PCB layout requirements. Ensure the 600 V blocking voltage aligns with the system's peak line voltage specifications to prevent breakdown during transient events.

Triacs Selection Notes

Select this component when high dV/dt immunity is required for inductive loads without external snubber networks. The 25 A RMS rating suits moderate power applications, while the 600 V rating fits standard 230 VAC mains environments. Consider the thermal resistance of the TO-220 package for heat dissipation needs in enclosed spaces compared to surface-mount alternatives like the BTB series.

Triacs Part Context

This part belongs to the BTA24 family of 25 A Snubberless Triacs manufactured by STMicroelectronics. The series includes variants such as the BTA24-600B and BTA24-600C, differentiated by their gate trigger characteristics and voltage ratings. These components are engineered for robust AC power control, offering a balance of high current handling and simplified circuit design due to integrated commutation capabilities.

Triacs Replacement Considerations

Equivalent parts include the BTA24-600BWRG and BTA24-600CWRG from STMicroelectronics. Cross-manufacturer replacements may require verification of gate trigger current limits and thermal resistance values to ensure compatibility with existing drive circuits and heatsinking arrangements.
