T12M10T800UB

Triacs Overview

The T12M10T800UB is a silicon bidirectional thyristor (Triac) manufactured by Diodes Incorporated. It features an 800 V repetitive peak off-state voltage and a 12 A RMS on-state current rating at +125°C. 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, a gate trigger current of 10 mA, and a holding current of 15 mA. It utilizes a TO220AB package with matte tin-plated leads.

Triacs Feature Summary

• Glass passivated for enhanced voltage ruggedness and reliability
• High voltage capability up to 800 V
• High junction operating temperature capability reaching +125°C
• Triggering in three quadrants only

Triacs Applications

• General-purpose motor controls
• Power control tools, electric drills, heating systems
• Home applications including fan controls, light dimmers, food processors, and coffee machines

Triacs Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status and lead-free finish specifications directly from the manufacturer's datasheet before procurement. Ensure the selected component matches the required thermal resistance and mounting style for the intended application environment.

Triacs Selection Notes

Select this component based on its 800 V blocking voltage and 12 A continuous current capacity. Verify that the 10 mA gate trigger current aligns with the driving circuit capabilities. Consider the TO220AB through-hole package dimensions and thermal characteristics when designing the PCB layout and heatsinking requirements for optimal performance.

Triacs Part Context

This Triac belongs to the T12M series of silicon bidirectional thyristors from Diodes Incorporated. It shares the same physical package and general electrical ratings as the T12M35T800UB, differing primarily in gate trigger sensitivity. Both devices are designed for robust industrial and consumer power control applications requiring high voltage handling.

Triacs Replacement Considerations

The T12M35T800UB is a direct functional substitute within the same series, sharing identical voltage, current, and package specifications. Differences exist solely in gate trigger current requirements (35 mA vs. 10 mA). Verify that the higher gate drive requirement of the replacement does not exceed the driving circuit's output capabilities.
