Q6016LH653

Triacs Overview

The Littelfuse Q6016LH653 is a high-reliability Alternistor TRIAC designed for AC switching and phase control applications. It features a 600 V rated repetitive off-state voltage (VDRM) and supports an RMS on-state current of 16 A. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum on-state voltage of 1.6 V, a gate trigger current of up to 80 mA, and a holding current of 70 mA. It utilizes a TO-220AB package with an isolated mounting surface.

Triacs Feature Summary

• Alternistor technology provides enhanced commutation capability for demanding AC loads
• Electrically isolated TO-220AB package eliminates the need for external insulators
• Glass-passivated junctions ensure long-term parameter stability and reliability

Triacs Applications

• Motor speed controls
• Temperature modulation controls
• Lighting controls
• Static switching relays

Triacs Procurement Notes

Verify the specific suffix '53' against official Littelfuse documentation to confirm it denotes a standard tube packaging variant rather than a custom specification. Ensure the selected component matches the required isolation voltage and thermal management specifications for the target application environment.

Triacs Selection Notes

Select this component when high dv/dt immunity is required in AC phase control circuits. The Alternistor structure allows operation in Quadrants I, II, and III, offering greater noise immunity compared to standard triacs. Confirm that the 80 mA maximum gate trigger current aligns with the driving circuit capabilities.

Triacs Part Context

This part belongs to the Teccor brand Qxx16xHx series of 16 Amp Alternistor Triacs. These devices are engineered for robust performance in industrial and consumer AC power control systems where reliable switching under transient conditions is critical.

Triacs Replacement Considerations

Compatible substitutes within the same family include Q6016LH1LEDTP and Q6016LH3TP. Verify pinout compatibility and thermal resistance characteristics before substitution.
