Q8016LH4TP

Triacs Overview

The Littelfuse Q8016LH4TP is a bidirectional triac designed for high-power switching applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2 V, and a gate trigger current of 35 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different conditions, with an on-state voltage of 1.6 V and a leakage current of 5 uA.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC power control environments
• Robust thermal performance allowing operation up to 125 °C junction temperature
• Standardized TO-220-2 mounting style facilitating integration into industrial heat sinks

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules for AC load switching
• Lighting dimmer circuits requiring high voltage isolation

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against the manufacturer's latest datasheet to confirm pinout configuration and packaging details. Ensure that the ordering information matches the exact RoHS compliance status and lead-free requirements specified in the official Littelfuse documentation before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC line voltages. Confirm that the 16 A RMS current capacity meets the load requirements. Verify that the gate drive circuit can supply the necessary 35 mA trigger current. Ensure the thermal management design accommodates the TO-220-2 package constraints for the expected operating temperature range.

Triacs Part Context

This part belongs to the Qxx16xHx series of triacs from Littelfuse. These devices are engineered for general-purpose AC power control. The series provides a balance of high voltage blocking and moderate current handling, making it a standard choice for industrial and commercial power electronics designs.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements must match the 800 V VDRM, 16 A IT(RMS), and TO-220-2 package dimensions. Verify gate sensitivity parameters to ensure compatibility with existing drive circuits.
