Q6012RH1LED

Triacs Overview

The Littelfuse Q6012RH1LED is a high-temperature, high dv/dt rated Triac designed for AC power control applications. It features an RMS on-state current of 12 A and a rated repetitive off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +150°C and utilizes a TO-220AB-3 package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.2 V, and a gate trigger current of 4 A.

Triacs Feature Summary

• High thermal stability with a maximum operating temperature of +150°C
• Enhanced immunity to false triggering via high dv/dt rating
• Robust surge handling capability with a non-repetitive peak on-state current of 153 A

Triacs Applications

• AC motor speed control in industrial equipment
• Solid-state relays requiring high thermal endurance
• Lighting dimmers for high-power resistive loads

Triacs Procurement Notes

Verify the specific suffix 'H' confirms the high dv/dt characteristic required for your application. Confirm the TO-220AB-3 package dimensions match your PCB footprint. Ensure the gate trigger current of 4 A is compatible with your driver circuit capabilities before finalizing the order.

Triacs Selection Notes

Select this component when standard Triacs fail due to high switching speeds or elevated ambient temperatures. The 12 A rating suits moderate power levels, while the 600 V blocking voltage provides safety margin for standard AC lines. Verify that the 4 mA gate drive requirement does not exceed your microcontroller output limits.

Triacs Part Context

This part belongs to Littelfuse's specialized Triac family engineered for demanding environments. Unlike standard devices, it prioritizes noise immunity and thermal resilience over low-cost consumer applications. It serves as a robust alternative for industrial controls where reliability under stress is critical.

Triacs Replacement Considerations

Direct substitutes must share the 12 A current rating, 600 V voltage rating, and TO-220AB-3 package. Verify equivalent high dv/dt specifications to prevent false triggering. Check if the replacement offers similar or lower gate trigger current requirements.
