T435-700H

Overview

The T435-700H is a Snubberless Triac from STMicroelectronics, rated for 700 V repetitive peak off-state voltage and 4 A RMS on-state current. It features a non-repetitive surge current capability of 31 A and operates within a junction temperature range of -40 °C to +125 °C. The device utilizes a DPAK surface-mount package and includes a gate trigger voltage of 1.3 V with a maximum holding current of 35 mA.

Feature Summary

• Snubberless logic level technology providing high commutation performance
• Suitable for AC inductive loads including universal motors and power tools
• Three-quadrant switching capability

Applications

• Universal motor control
• Electro valves
• Kitchen aid equipment
• Power tools
• Dishwashers

Procurement Notes

Verify the specific suffix 'H' against official STMicroelectronics documentation to confirm exact pinout and thermal characteristics. Ensure the selected component matches the required 700V rating and DPAK package form factor for the intended design.

Selection Notes

Select this component for applications requiring robust commutation without external snubber circuits. Confirm that the load current does not exceed the 4A RMS limit and that the operating environment stays within the specified -40°C to +125°C temperature range.

Part Context

This part belongs to the T435 series of Snubberless Triacs designed by STMicroelectronics. The series is engineered for general-purpose mains power AC switching, offering high immunity to false turn-on and improved turn-off capabilities in high-temperature environments compared to traditional triacs.

Replacement Considerations

Check for direct substitutes within the T435 family or other STMicroelectronics Snubberless Triac series with matching voltage and current ratings. Verify package compatibility and thermal resistance requirements before substituting.
