QJ6016NH4RP

Triacs Overview

The Littelfuse QJ6016NH4RP is a high-temperature Alternistor TRIAC designed for robust AC switching 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. Packaged in a surface-mount D2PAK-2 (TO-263-2) configuration, it offers low on-state voltage of 1.6 V and a maximum holding current of 60 mA. Key gate parameters include a trigger voltage of 1.3 V and a trigger current of 50 mA, facilitating efficient control.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C for enhanced thermal stability
• Integrated snubberless design eliminates the need for external RC networks
• Surface-mount D2PAK-2 package optimized for automated PCB assembly

Triacs Applications

• Industrial motor speed controls
• High-power lighting dimmers
• Temperature modulation systems

Triacs Procurement Notes

Verify the specific suffix '4' against official Littelfuse documentation to confirm exact gate characteristics, as variations exist within the QJ6016 series. Ensure compatibility with the D2PAK-2 footprint during procurement planning. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing orders.

Triacs Selection Notes

Select this component when operating temperatures exceed standard triac limits or when snubberless operation is required. Compare the 60 mA holding current against load requirements to prevent unintended turn-off. Verify that the 1.3 V gate trigger voltage aligns with the driving circuit's output capabilities for reliable switching.

Triacs Part Context

This part belongs to the QJxx16xHx series of Alternistor TRIACs from Littelfuse. These devices are engineered for high-reliability applications requiring superior thermal performance compared to standard TO-220 packages. The QJ series specifically targets industrial and commercial markets where space constraints and heat dissipation are critical design factors.

Triacs Replacement Considerations

Direct substitutes may include other snubberless TRIACs in the D2PAK-2 package with matching 600 V and 16 A ratings. Verify pinout compatibility and thermal resistance values. Cross-reference gate trigger specifications to ensure equivalent drive requirements without redesigning the control circuitry.
