QJ8016RH4TP

Triacs Overview

The Littelfuse QJ8016RH4TP is a high-performance TRIAC designed for robust AC power control applications. It features an RMS on-state current of 16 A and a rated repetitive peak off-state voltage of 800 V. The device operates within a junction temperature range from -40°C to +150°C, ensuring reliability in demanding environments. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2 V, and a gate trigger current of 35 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 5 µA at the rated voltage. The component is housed in a TO-263AB-3 package, suitable for surface-mount technology.

Triacs Feature Summary

• High thermal stability with a maximum operating temperature of 150°C
• Robust switching capability with 16 A RMS current handling
• Sensitive gate drive requirements for efficient triggering

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-power lighting dimmers

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against official Littelfuse documentation to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure that the TO-263AB-3 footprint matches the target PCB design guidelines. Cross-reference the datasheet revision date to validate all electrical limits before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with high thermal endurance is required. Compare the 150°C rating against standard 125°C devices for superior overload tolerance. Verify that the 800V blocking voltage meets the circuit's peak line voltage requirements. Confirm that the TO-263AB-3 package allows adequate thermal dissipation for the intended load current without excessive heatsinking.

Triacs Part Context

This part belongs to the Qxx16xHx series of TRIACs from Littelfuse, which are engineered for general-purpose AC switching. The series offers a balance of high current density and compact surface-mount packaging. It serves as a modern alternative to through-hole equivalents in space-constrained industrial designs requiring reliable AC phase control.

Triacs Replacement Considerations

Direct pin-compatible replacements may include other 16A 800V TRIACs in TO-263 packages from Littelfuse or competitors. Verify gate sensitivity and dv/dt ratings match the original circuit design. Check if alternative manufacturers offer equivalent thermal resistance values for the same package type.
