Q8016RH4

Triacs Overview

The Littelfuse Q8016RH4 is a bidirectional triac designed for high-voltage AC power control applications. It features an RMS on-state current rating of 16 A and a repetitive peak off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range from -40 °C to +125 °C. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2 V, and a gate trigger current of 35 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 5 µA at rated voltage. The component is housed in a TO-220-2 through-hole package.

Triacs Feature Summary

• High voltage blocking capability suitable for industrial AC switching
• Robust thermal performance with extended operating temperature range
• Low on-state voltage drop for improved efficiency

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for AC loads
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Littelfuse documentation before procurement. Confirm RoHS compliance status and REACH SVHC declarations via the current datasheet. Ensure the supplier provides traceable components matching the exact Q8016RH4 specification to avoid counterfeit risks.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current are required in a through-hole configuration. Compare gate trigger requirements against the driving circuit capabilities, noting the 35 mA gate current specification. Evaluate thermal management needs based on the TO-220-2 package and expected load conditions.

Triacs Part Context

This triac belongs to the Qxx16xHx series from Littelfuse, which groups devices sharing similar current ratings and package styles. The Q8016RH4 specifically denotes the 800 V variant within this family, distinguishing it from other voltage ratings like 1 kV or 600 V options available in the same series.

Triacs Replacement Considerations

Direct replacements must match the 800 V VDRM, 16 A IT(RMS), and TO-220-2 package. Verify pinout compatibility and gate sensitivity parameters. Cross-reference with equivalent parts from other manufacturers ensuring identical electrical ratings and mechanical dimensions.
