QJ8016NH4TP

Triacs Overview

The Littelfuse QJ8016NH4TP is a high-temperature Alternistor TRIAC rated for 800 V repetitive off-state voltage and 16 A RMS on-state current. It features a non-latching gate structure with a maximum holding current of 50 mA and a typical on-state voltage of 1.6 V. The device supports a non-repetitive surge current of 200 A and operates within a junction temperature range of -40 °C to +150 °C. Packaged in a surface-mount TO-263AB-3 (D2PAK) housing, it provides robust performance for industrial power control applications requiring high thermal stability.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C junction temperature
• Non-latching gate design for reliable triggering
• Surface-mount TO-263AB-3 package for automated assembly

Triacs Applications

• Industrial motor control systems
• Solid-state relays
• High-temperature power switching circuits

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm the tube packaging configuration, as suffixes can indicate variations in reel or tape specifications. Ensure the requested quantity aligns with standard factory pack sizes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate RoHS compliance status and current production lifecycle stage before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current capacity are required in a surface-mount form factor. The TO-263AB-3 package offers superior thermal dissipation compared to smaller SMD options. Consider the 1.6 V on-state voltage for efficiency calculations. This device is suitable for designs prioritizing high-temperature reliability over lower-cost through-hole alternatives.

Triacs Part Context

This part belongs to the Littelfuse Alternistor series, designed for high-temperature thyristor applications. The QJ prefix typically denotes the 800 V rating class within the family. The device utilizes advanced silicon gate technology to ensure stable switching characteristics under demanding electrical conditions, distinguishing it from standard low-temperature TRIACs.

Triacs Replacement Considerations

Direct substitutes include the QJ8016NH4RP, which shares identical electrical ratings but differs in packaging format. Verify pinout compatibility and thermal resistance values when transitioning between tube and reel variants to ensure proper board layout integration.
