T410-800B

Overview

The T410-800B is a logic-level Triac from the STMicroelectronics T410 series, designed for AC inductive load control. It features an 800 V repetitive peak off-state voltage and a 4 A RMS on-state current capability. The device utilizes Snubberless technology to ensure high commutation performance without external snubber circuits. Key electrical parameters include a maximum non-repetitive surge current of 31 A, a holding current of 15 mA, and a gate trigger voltage of 1.3 V. It operates within a junction temperature range of -40°C to +125°C and is housed in a surface-mount DPAK package.

Feature Summary

• Logic-level sensitivity allows direct drive from microcontrollers or low-power logic gates.
• Snubberless design simplifies circuit topology by eliminating the need for external RC snubbers.
• High commutation performance ensures reliable switching with inductive loads.

Applications

• Universal motor speed control
• Electro-valve actuation
• Kitchen appliance power regulation

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and manufacturing origin through authorized distributors. Ensure the ordering code matches the required surface-mount configuration for your PCB layout.

Selection Notes

Select this component when a surface-mount solution is required for AC switching applications. The logic gate sensitivity reduces driver complexity compared to standard gate Triacs. Verify that the 800 V rating exceeds the peak line voltage plus transient spikes in the target application environment.

Part Context

This part belongs to the T410 family of Snubberless Triacs. The T4 series is optimized for AC switch applications requiring high reliability and simplified design. The T410-800B specifically denotes the 800 V blocking voltage variant in the DPAK package.

Replacement Considerations

Check for equivalent logic-level Triacs in DPAK packages with matching 800 V and 4 A ratings. Verify pinout compatibility and thermal characteristics before substitution. Consult manufacturer cross-reference guides for validated alternatives.
