QK016RH3TP

Triacs Overview

The QK016RH3TP is a high-voltage triac manufactured by Littelfuse, designed for robust AC power switching applications. It features a rated repetitive peak off-state voltage (VDRM) of 800 V and an RMS on-state current (IT(RMS)) of 16 A. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical characteristics include a maximum holding current of 70 mA and a gate trigger current of 35 mA. It exhibits a low on-state voltage of 1.6 V and a maximum non-repetitive peak on-state current of 167 A or 200 A depending on pulse width. The component is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC line applications
• Surface-mount construction for automated PCB assembly
• Low on-state voltage for improved efficiency
• Robust thermal performance over extended temperature ranges

Triacs Applications

• Solid state relays
• Industrial motor controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and electrical tolerances. Ensure the ordering quantity aligns with manufacturer minimums. Confirm RoHS compliance status through the latest datasheet revision. Validate that the SMTO-263-2 footprint matches the target PCB design requirements before finalizing procurement.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC switching. Compare gate sensitivity requirements against the 35 mA trigger current specification. Ensure the thermal management solution supports the 16 A RMS current capacity. Verify compatibility with surface-mount reflow processes given the SMTO-263-2 package type.

Triacs Part Context

This part belongs to the Qxx16xHx series of triacs from Littelfuse. The series offers various voltage ratings including 600 V, 800 V, and 1000 V options. All variants share similar current handling capabilities and packaging styles, differing primarily in breakdown voltage and gate characteristics.

Triacs Replacement Considerations

Direct substitutes may include other 800 V, 16 A triacs in SMTO-263 packages from Littelfuse or competitors. Verify equivalent VDRM, IT(RMS), and package dimensions. Check for compatible gate trigger parameters to ensure circuit functionality without modification.
