Q6016RH4TP

Triacs Overview

The Littelfuse Q6016RH4TP is a 16 A Alternistor TRIAC rated for 600 V in a TO-220AB non-isolated package. It operates in Quadrants I, II, and III with a maximum gate trigger current of 35 mA. Key electrical parameters include an on-state RMS current of 16 A at 90 °C case temperature, a peak non-repetitive surge current of 200 A at 60 Hz, and a holding current maximum of 50 mA. The device features a peak on-state voltage of 1.6 V and supports junction temperatures from -40 °C to 125 °C.

Triacs Feature Summary

• Alternistor design eliminates the need for external snubber networks in highly inductive loads
• Non-isolated mounting tab allows direct heat sinking without additional insulators
• Limited RFI generation depending on activation point in sine wave

Triacs Applications

• AC switching and phase control applications such as heating, lighting, and motor speed control
• Power tools
• White goods appliances
• Applications with extremely inductive loads requiring high commutation performance

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and sensitivity class. Ensure that the non-isolated tab configuration aligns with the thermal management and isolation requirements of the target circuit design before finalizing procurement.

Triacs Selection Notes

Select this component when high commutation performance is required for inductive loads without adding external snubber components. Confirm that the 600 V blocking voltage and 16 A RMS current rating meet the system's operational demands. Verify compatibility with the driving circuit's ability to supply the specified 35 mA gate trigger current.

Triacs Part Context

This part belongs to the Qxx16xHx series of 16 A Alternistor TRIACs manufactured by Littelfuse. The 'R' designation indicates a TO-220AB package with a non-isolated mounting tab, distinguishing it from the electrically isolated 'L' package variant within the same product family.
