Q8012NH5TP

Triacs Overview

The Littelfuse Q8012NH5TP is a bidirectional triac from the Teccor Qxx12xHx series, designed for AC power 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 characteristics include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA.

Triacs Feature Summary

• High-voltage blocking capability suitable for mains-connected loads
• Surface-mount construction for automated PCB assembly
• Sensitive gate drive requirements for low-power triggering

Triacs Applications

• Solid-state relays
• AC motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure the ordering code matches the required package variant. Confirm RoHS compliance status through the latest environmental declaration documents provided by Littelfuse before finalizing procurement.

Triacs Selection Notes

Select this component when an 800 V rating and 12 A continuous current are required in a compact surface-mount form factor. Compare the 70 mA holding current against load characteristics to prevent unintended turn-off. Verify that the gate drive circuit can supply the specified 50 mA trigger current reliably across the operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx12xHx family of high-voltage triacs. These devices are engineered for robust performance in industrial and consumer AC switching environments. The SMTO-263-2 package provides efficient thermal dissipation relative to its footprint, supporting reliable operation in dense circuit layouts.

Triacs Replacement Considerations

Consult the Littelfuse Triac Cross Reference Guide for verified substitutes. Ensure any replacement maintains the 800 V voltage rating and 12 A current capacity while matching the SMTO-263-2 package dimensions.
