OT411,127

Triacs Overview

The OT411,127 is a general-purpose Triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 10 A and a rated repetitive off-state voltage of 600 V. The device is housed in a TO-220F-3 package with through-hole mounting. Key electrical parameters include a maximum non-repetitive on-state current of 110 A, a holding current of 60 mA, and a gate trigger voltage of 800 mV. It operates at a maximum temperature of +150°C.

Triacs Feature Summary

• Provides bidirectional current control for AC power switching applications
• Features an isolated tab design within the TO-220F-3 package for efficient heat dissipation
• Designed for general-purpose thyristor operations with standard triggering characteristics

Triacs Applications

• AC motor speed control circuits
• Lighting dimmer switches
• Solid-state relay inputs
• General industrial AC power regulation

Triacs Procurement Notes

Verify component authenticity through authorized WeEn Semiconductors distributors or certified partners. Request original manufacturer datasheets to confirm lot codes and RoHS compliance status. Ensure supply chain documentation matches the specific ordering suffix. Validate thermal management requirements against the specified maximum operating temperature limits before final integration.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 600 V blocking voltage are required for AC switching. The TO-220F-3 package suits applications needing robust thermal performance with isolated mounting. Consider the 800 mV gate trigger voltage for driver compatibility. Evaluate thermal resistance constraints relative to the 75 W power dissipation capability in the intended enclosure environment.

Triacs Part Context

This Triac belongs to the general-purpose thyristor family from WeEn Semiconductors. It complements other devices like the BTA410X series by offering similar current handling in a standard through-hole format. The component serves as a fundamental building block for phase-control circuits requiring reliable bidirectional conduction in medium-power AC systems.

Triacs Replacement Considerations

Cross-reference with equivalent 10 A, 600 V Triacs in TO-220 packages. Verify pinout compatibility and thermal characteristics. Confirm that alternative parts meet the same gate trigger current and voltage specifications for direct circuit substitution without redesign.
