Q8012NH5RP

Triacs Overview

The Littelfuse Q8012NH5RP is a bidirectional triac from the Teccor family, designed for AC switching and phase control applications. It features an RMS on-state current of 12 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40 °C to +125 °C and utilizes an SMTO-263-2 surface-mount package. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger current of 50 mA, and a typical on-state voltage of 1.6 V.

Triacs Feature Summary

• Integrated glass-passivated junctions for long-term parameter stability
• High commutation robustness with specified dv/dt ratings
• Surface-mount construction optimized for automated assembly

Triacs Applications

• AC motor speed controls
• Lighting dimmer circuits
• Temperature modulation systems

Triacs Procurement Notes

Verify the specific suffix 'H5RP' against the official Littelfuse datasheet to confirm the exact packaging configuration and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel or cut-tape specifications. Cross-reference the part number with the latest revision history to avoid obsolete stock.

Triacs Selection Notes

Select this component when an 800 V blocking capability and 12 A continuous load are required in a compact surface-mount form factor. Compare the 50 mA gate trigger requirement against available driver circuitry capabilities. Evaluate thermal management needs based on the 1.6 V on-state voltage drop at full load conditions.

Triacs Part Context

This device belongs to the Qxx12xHx series of Triacs manufactured by Littelfuse under the Teccor brand. It shares functional similarities with other 800 V/12 A variants but differs in package style and triggering characteristics. The series is engineered for general-purpose AC power control where noise immunity and reliability are critical.

Triacs Replacement Considerations

Direct substitutes include the Q8012LH2 and Q8012RH5TP. Verify pinout compatibility and ensure the replacement maintains the same 800 V rating and 12 A current capacity. Confirm that the alternative package type fits the existing PCB footprint.
