QJ6016LH4TP

Triacs Overview

The Littelfuse QJ6016LH4TP is a high-temperature bidirectional triac designed for robust power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 16 A. The device supports a non-repetitive peak on-state current of 200 A, ensuring resilience against surge conditions. Key electrical parameters include a maximum holding current of 15 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. The component operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 through-hole package.

Triacs Feature Summary

• High-temperature operation capability up to 150°C for demanding environments
• Isolated construction in a TO-220-2 package for enhanced safety
• Sensitive gate drive characteristics with low trigger current requirements

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-temperature heating element regulation

Triacs Procurement Notes

Verify the specific suffix '4TP' against official Littelfuse documentation to confirm tape-and-reel packaging and exact manufacturing lot details. Ensure compatibility with existing thermal management designs given the 150°C junction temperature rating. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 600 V, 16 A triac with isolated mounting is required for high-temperature industrial use. Compare the 10 mA gate trigger current against driver capabilities to ensure sufficient triggering margin. Evaluate thermal resistance requirements for the TO-220-2 package under continuous 16 A load conditions.

Triacs Part Context

This part belongs to the QJxx16xHx series of high-temperature triacs from Littelfuse. The series is characterized by its ability to operate at elevated temperatures compared to standard triacs. The QJ prefix typically denotes specific isolation or packaging variations within the broader Q family of thyristors.

Triacs Replacement Considerations

Direct substitutes may include other 600 V, 16 A isolated triacs in TO-220 packages. Verify equivalent gate sensitivity and thermal ratings. Check for pin-compatible alternatives from manufacturers like STMicroelectronics or Vishay if Littelfuse supply is constrained.
