BTB24-700BRG

Triacs Overview

The STMicroelectronics BTB24-700BRG is a Snubberless Triac rated for 25 A RMS current with a 700 V repetitive peak off-state voltage. It utilizes high-performance glass passivated chip technology and clip assembly to ensure superior surge handling capabilities. The device features a TO-220AB package with an electrically isolated tab, supporting through-hole mounting. Key electrical parameters include a maximum non-repetitive surge current of 260 A, a holding current of 80 mA, and a gate trigger current of 100 mA. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks in general-purpose AC switching applications.
• Clip assembly technique provides enhanced thermal performance and robust surge current handling.
• Electrically isolated tab allows direct heatsink mounting without additional insulation components.

Triacs Applications

• Phase control circuits for resistive or inductive loads
• Static switching applications in mains power systems
• General purpose AC power regulation

Triacs Procurement Notes

Verify the specific voltage rating suffix against the datasheet, as the BTB24 series includes variants such as 600V and 800V. Confirm that the BRG suffix corresponds to the required RoHS compliance and tube packaging format. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Triacs Selection Notes

Select this component when a 25 A RMS triac with a 700 V blocking capability is required. The Snubberless feature simplifies circuit design by removing external damping networks. Verify that the load characteristics align with the 4-quadrant commutation capability and that the thermal management solution accommodates the TO-220AB package constraints.

Triacs Part Context

This part belongs to the BTB24 series of Snubberless Triacs from STMicroelectronics. The series is designed for general-purpose AC switching and shares common features like glass passivation and clip bonding. Other variants in the family include different voltage ratings and package options, such as the BTA24 surface-mount version.

Triacs Replacement Considerations

Direct replacements within the same series include the BTB24-600BRG (600 V) and BTB24-800BRG (800 V), provided the voltage margin is sufficient. Cross-series alternatives may include the BTA24 or T25 families, though pinout and thermal resistance differences must be evaluated.
