Q6016LH4TP

Triacs Overview

The Littelfuse Q6016LH4TP is a 16 A Alternistor TRIAC from the Qxx16xHx series, rated for 600 V repetitive off-state voltage. It operates in Quadrants I, II, and III with a maximum DC gate trigger current of 35 mA and holding current of 50 mA. The device features a peak on-state voltage of 1.6 V at 22.6 A and supports non-repetitive surge currents up to 200 A. Packaged in an electrically isolated TO-220AB (L-Package) with a 2500 VRMS isolation rating, it functions within a junction temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Alternistor design enables high commutation performance without requiring external snubber networks.
• Electrically isolated mounting tab provides 2500 VRMS isolation between leads and heatsink.
• Glass-passivated junctions ensure long-term parameter stability and reliability.
• Limited RFI generation during AC switching operations.

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 highest commutation performance

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the isolated TO-220AB L-package variant. Ensure ordering suffixes align with specific sensitivity and voltage ratings required for the target circuit design.

Triacs Selection Notes

Select this part for circuits requiring high commutation capability in inductive loads where snubber networks are undesirable. The 35 mA gate sensitivity suits standard drive circuits. Verify thermal management requirements based on the 1.7 K/W junction-to-case resistance for proper heat sinking.

Triacs Part Context

This component belongs to the Qxx16xHx series of 16 A Alternistor TRIACs manufactured by Littelfuse. The series offers various voltage ratings and gate sensitivities, packaged in isolated or non-isolated configurations for diverse power control needs.

Triacs Replacement Considerations

Compatible substitutes include other parts within the Qxx16xHx family, such as Q6016RH4TP (non-isolated) or Q6016NH4TP (TO-263 surface mount), provided electrical ratings and package compatibility match the application requirements.

Triacs FAQ
