Q8012NH2RP

Triacs Overview

The Littelfuse Q8012NH2RP is a Triac from the Teccor brand, designed for AC switching and phase control applications. It features an Alternistor structure with high commutation capability, operating in quadrants I, II, and III. The device has a maximum RMS on-state current of 12 A and a repetitive peak off-state voltage of 800 V. It utilizes a TO-220AB insulated package for flange mounting. Key electrical parameters include a maximum DC gate trigger current of 10 mA, a maximum DC gate trigger voltage of 1.3 V, and a minimum critical rate of rise of off-state voltage of 150 V/us.

Triacs Feature Summary

• Alternistor design provides high dv/dt capability for demanding circuits
• Electrically isolated L-Package construction ensures safety isolation
• RoHS compliant manufacturing process

Triacs Applications

• Motor speed modulation controls
• Temperature modulation systems
• Lighting controls
• Static switching relays

Triacs Procurement Notes

Verify the specific suffix 'H2RP' against official Littelfuse documentation to confirm pinout configuration and packaging details. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet for thermal management specifications suitable for the intended load conditions.

Triacs Selection Notes

Select this component for applications requiring high commutation robustness and bidirectional switching up to 800 V. The Alternistor technology is suitable for circuits sensitive to rapid voltage changes. Consider the TO-220AB package for effective heat dissipation when handling continuous currents near the 12 A rating.

Triacs Part Context

This part belongs to the Qxx12xHx series of 12 Amp bi-directional solid state switches. The series is engineered for AC switching and phase control tasks. The 'Q8012' designation indicates the 12 A current class and 800 V voltage rating within the broader Teccor thyristor product line.

Triacs Replacement Considerations

Check for direct substitutes within the Qxx12xHx family or equivalent 12 A / 800 V Alternistor Triacs. Verify that any replacement maintains the same quadrant operation (I, II, III) and dv/dt ratings to ensure circuit compatibility.
