Q6016LH651

Triacs Overview

The Littelfuse Q6016LH651 is a 16 A Alternistor triac with a 600 V rated repetitive off-state voltage. It utilizes Snubberless technology for high commutation performance in TO-220-2 through-hole packages. Key electrical parameters include a 1.6 V on-state voltage, 80 mA gate trigger current, and 70 mA holding current. The device operates within a -40 C to +125 C temperature range and features an isolated tab for mounting.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks
• High commutation capability suitable for demanding AC switching applications
• Isolated tab construction facilitates efficient thermal management

Triacs Applications

• Solid state relays
• Motor speed control circuits
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific suffix '51' against official Littelfuse documentation to confirm package isolation and pinout configuration. Ensure compatibility with existing PCB thermal pads and verify that the TO-220-2 footprint matches the target assembly requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when high dv/dt immunity and snubberless operation are required. The 16 A RMS rating supports moderate power loads. Consider the 600 V blocking voltage for standard AC line applications. Verify thermal dissipation needs relative to the TO-220-2 package constraints.

Triacs Part Context

This part belongs to the Q6016xH series of Alternistors from Littelfuse. These devices are engineered for high-reliability AC power control. The series emphasizes robust commutation characteristics and simplified circuit design by removing passive snubber components.

Triacs Replacement Considerations

Cross-reference with Q6016LH6TP or Q6016RH6TP for similar 16 A/600 V specifications. Confirm that the alternative part number maintains the same TO-220-2 isolated tab configuration and Snubberless functionality.
