BTA25-700B

Triacs Overview

The BTA25-700B is a bidirectional triac from STMicroelectronics designed for general-purpose mains power AC switching. It features an I(T,RMS) rating of 25 A and a repetitive peak off-state voltage (V(DRM)/V(RRM)) of 700 V. The device supports a non-repetitive surge current of 260 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current of 100 mA, a maximum holding current of 80 mA, and a peak on-state voltage of 1.7 V. It utilizes the RD-91 package for panel mounting.

Triacs Feature Summary

• Snubberless design capability allows suppression of RC networks, simplifying circuit topology for inductive or resistive loads.
• High commutation performance across four quadrants ensures reliable switching in demanding AC applications.
• Clip assembly technique provides superior thermal management and enhanced surge current handling capabilities.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm exact electrical tolerances and packaging details. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 700 V blocking voltage are required for AC load control. The Snubberless feature makes it suitable for designs aiming to minimize external passive components. Verify that the RD-91 package dimensions fit the mechanical constraints of the intended panel mount application.

Triacs Part Context

The BTA25-700B belongs to the BTA25 series of high-current triacs from STMicroelectronics. This series is engineered for robust performance in mains-powered applications, offering a balance of high current handling and efficient thermal dissipation through clip bonding technology.

Triacs Replacement Considerations

Compatible alternatives within the same family include the BTA25-600B and BTA25-800B, which share identical current ratings but differ in voltage blocking capabilities. Ensure voltage ratings match the application requirements when substituting.
