QV6016NH4TP

Triacs Overview

The Littelfuse QV6016NH4TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 600 V rated repetitive off-state voltage (VDRM) and supports an on-state RMS current (ITRMS) of 16 A. The device operates within a junction temperature range of -40 °C to +150 °C, ensuring reliability in demanding thermal 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 VDRM. Packaged in a TO-220L-3 through-hole case, it offers high dv/dt immunity suitable for industrial switching.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C junction temperature
• Alternistor technology providing enhanced commutation robustness and high dv/dt immunity
• Low on-state voltage drop for improved efficiency in power control circuits

Triacs Applications

• Industrial motor speed control systems
• High-temperature lighting dimming applications
• Solid-state relays requiring robust switching performance

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging requirements. Ensure the TO-220L-3 package dimensions match the target PCB footprint. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement specifications.

Triacs Selection Notes

Select this component when operating temperatures exceed standard 125 °C limits or when high dv/dt immunity is critical. Compare gate trigger currents with driver capabilities to ensure reliable turn-on. Verify that the 16 A ITRMS rating accommodates peak load demands without exceeding thermal constraints in the intended enclosure design.

Triacs Part Context

This part belongs to the QVxx16xHx series of high-temperature TRIACs from Littelfuse. It shares core electrical characteristics with the Q6016NH4TP but utilizes a different through-hole package (TO-220L-3) compared to the surface-mount SMTO-263-2 variant. The series is engineered for applications requiring superior thermal stability and switching reliability under harsh conditions.

Triacs Replacement Considerations

Direct pin-compatible replacements may include other Littelfuse Alternistor TRIACs in the TO-220L-3 package with matching 600 V and 16 A ratings. Verify gate trigger parameters and thermal resistance values when substituting with components from other manufacturers to ensure circuit compatibility.
