QJ6016NH2RP

Triacs Overview

The Littelfuse QJ6016NH2RP is a bidirectional triac belonging to the QJxx16xHx series, designed for high-temperature AC power control applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum holding current (Ih) of 60 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 50 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 5 µA at VDRM. The component is housed in a D2PAK-2 (TO-263-2) surface-mount package.

Triacs Feature Summary

• High-temperature operation capability with a maximum junction temperature of +150°C
• Integrated gate control for reliable AC switching and phase modulation
• Low on-state voltage drop for improved thermal efficiency
• Surface-mount construction for automated PCB assembly

Triacs Applications

• High-temperature AC power control circuits
• Solid-state relays requiring robust thermal performance
• Industrial motor speed control systems
• Resistive load switching applications

Triacs Procurement Notes

Verify the specific suffix 'QJ' against the required datasheet specifications, as it denotes the high-temperature variant distinct from standard Q-series devices. Confirm that the D2PAK-2 footprint matches the target PCB layout. Ensure the gate trigger characteristics align with the driving circuit's output capabilities before finalizing procurement orders.

Triacs Selection Notes

Select this component when application environments exceed standard triac ratings or require extended thermal margins up to +150°C. The 16 A current rating suits moderate-power AC loads. Verify that the 60 mA holding current does not cause unintended latching in low-current standby modes. Compare against the Q6016NH series if lower operating temperatures are sufficient for the design.

Triacs Part Context

This part belongs to the QJxx16xHx family of high-temperature alternistors/triacs from Littelfuse. Unlike standard TO-220 packages, this model utilizes a surface-mount D2PAK-2 form factor. The 'QJ' prefix specifically identifies the high-temperature grade, differentiating it from the Q6016NH variants which typically support lower maximum junction temperatures.

Triacs Replacement Considerations

Direct replacements include other Littelfuse QJxx16xHx series parts with matching voltage and current ratings. Cross-brand equivalents must be verified for identical pinout compatibility, thermal resistance characteristics, and gate sensitivity parameters to ensure functional interchangeability.
