T12M10T800UD

Triacs Overview

The T12M10T800UD is a silicon bidirectional thyristor (Triac) manufactured by Diodes Incorporated, housed in a TO-220AB package. It supports an RMS on-state current of 12 A and a repetitive peak off-state voltage of 800 V. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum on-state voltage of 1.6 V at 12 A, a gate trigger current of 10 mA, and a holding current of 15 mA. Thermal resistance values are specified as 6.9°C/W (junction-to-ambient), 2.3°C/W (junction-to-case), and 2.2°C/W (junction-to-lead).

Triacs Feature Summary

• Glass passivation provides enhanced voltage ruggedness and reliability.
• Internally insulated package design for safety isolation.
• Capable of triggering in three quadrants only.

Triacs Applications

• General-purpose motor controls
• Power control tools and electric drills
• Home appliance fan controls and light dimmers

Triacs Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets RoHS compliance standards and halogen-free requirements before procurement. Ensure the selected distributor sources directly from authorized channels to guarantee product authenticity and traceability.

Triacs Selection Notes

Select this component when an 800 V blocking capability and 12 A continuous current rating are required. Verify that the 10 mA gate trigger current aligns with the driving circuit's output capabilities. Consider the thermal resistance specifications and ensure adequate heatsinking is implemented to maintain the junction temperature within the specified operating limits during high-load conditions.

Triacs Part Context

This part belongs to the T12MxxT800UD series of Triacs from Diodes Incorporated. It shares identical mechanical dimensions and core electrical ratings with the T12M35T800UD variant. The primary distinction between these models lies in their gate trigger current specifications, which dictate the sensitivity of the triggering mechanism.

Triacs Replacement Considerations

The T12M35T800UD serves as a direct functional substitute within the same series, sharing identical voltage, current, and package specifications. When replacing components, verify that the higher gate trigger current of the alternative does not exceed the drive circuit's capacity.

Triacs FAQ
