Q8016RH3TP

Triacs Overview

The Q8016RH3TP is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features an 800V repetitive peak off-state voltage and a 16A RMS on-state current rating. The device utilizes a sensitive gate structure with a maximum gate trigger current of 20mA. It is housed in a TO-220-2 package to facilitate thermal management. Key electrical characteristics include a holding current of 50mA and a non-repetitive peak surge current capability of 150A. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Sensitive gate architecture enabling direct interfacing with low-power logic circuits
• High surge current handling capacity for robust protection against transient loads
• Thermal design optimized for high-power density mounting via standard leaded package

Triacs Applications

• Solid-state relays for industrial switching
• AC motor speed control systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'H3' against the manufacturer's latest datasheet to confirm pinout configuration and gate sensitivity class. Ensure the TO-220-2 package variant matches the thermal requirements of the target PCB layout. Cross-reference the RoHS compliance status with current environmental declarations before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 16A continuous current are required in a through-hole package. The sensitive gate specification allows for drive from standard microcontroller GPIOs without additional amplification. Evaluate the thermal resistance of the TO-220-2 package against the expected ambient temperature and heat sinking strategy to ensure junction temperatures remain within safe operating limits during continuous conduction.

Triacs Part Context

This part belongs to the Qxx16xHx series of high-voltage triacs from Littelfuse. The series is engineered for general-purpose AC power switching where reliable commutation and high surge tolerance are critical. The Q8016RH3TP represents a specific voltage and current rating within this family, distinguished by its 800V rating and sensitive gate trigger characteristics suitable for modern digital control interfaces.

Triacs Replacement Considerations

Direct substitutes may include other 800V 16A sensitive gate triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify that any alternative part maintains identical pinout compatibility and gate trigger current specifications to ensure circuit functionality without redesign.
