Q8016LH4

Triacs Overview

The Littelfuse Q8016LH4TP is a bidirectional triac belonging to the Qxx16xHx series, designed for through-hole mounting in TO-220-2 packages. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum holding current of 50 mA, with gate trigger parameters specified at 35 mA and 2 V. Non-repetitive peak on-state currents are rated at 167 A and 200 A under different conditions. On-state voltage is 1.6 V, while leakage current remains at 5 uA. Operating temperatures range from -40 C to +125 C.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC power control applications
• Robust thermal performance enabled by the TO-220-2 through-hole package design
• Defined gate sensitivity characteristics for reliable triggering in thyristor circuits

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Industrial heating element regulation

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Ensure the component matches the required voltage and current ratings for the target circuit design before procurement.

Triacs Selection Notes

Select this component based on the 800 V blocking voltage and 16 A continuous current requirements. Consider the TO-220-2 package for adequate heat dissipation and verify that the gate trigger current aligns with the driving circuit capabilities.

Triacs Part Context

This part belongs to the Littelfuse Qxx16xHx family of high-power thyristors. These devices are engineered for robust operation in industrial environments requiring reliable switching of significant AC loads.

Triacs Replacement Considerations

The Q8016LH3TP is a documented alternative within the same series, distinguished primarily by its lower gate trigger current specification of 20 mA compared to the 35 mA of the LH4 variant.
