Q8010R4TP

Triacs Overview

The Littelfuse Q8010R4TP is a bidirectional triac designed for power control applications. It features an RMS on-state current of 10 A and a rated repetitive peak off-state voltage of 800 V. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220-3 through-hole package. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current ranging from 25 mA to 50 mA. Non-repetitive peak on-state currents are specified at 100 A and 120 A, with an on-state voltage of 1.6 V and a leakage current of 10 uA.

Triacs Feature Summary

• High thermal stability supporting operation up to 150°C
• Robust 800V blocking capability for high-voltage AC switching
• Low gate sensitivity facilitating direct drive from logic circuits

Triacs Applications

• Solid-state relays
• AC motor speed control
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix R4 against official Littelfuse documentation to confirm pinout configuration and thermal pad requirements. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with distributor listings to avoid counterfeit components. Confirm that the TO-220-3 package matches the intended PCB footprint and mounting constraints.

Triacs Selection Notes

Select this component when an 800V rating is required for AC loads exceeding 10A RMS. Compare the 35mA holding current against load characteristics to prevent unintended turn-off. Evaluate the 1.3V gate trigger voltage against the driving circuit's output capability. Consider the TO-220-3 package for adequate heat dissipation in high-power scenarios without active cooling.

Triacs Part Context

This triac belongs to the QJxx10xx series from Littelfuse, which focuses on general-purpose power control. The Q8010R4TP shares core electrical specifications with other variants in the family but differs in packaging and specific gate characteristics. It serves as a standard solution for industrial AC switching where reliability and high voltage tolerance are critical.

Triacs Replacement Considerations

Direct substitutes include the Q8010N4TP (SMTO-263-2 package) and Q8010R5TP (TO-220-2 package). Verify pin compatibility and thermal performance before substitution. The Q8010R5TP has different gate trigger specifications and a lower maximum operating temperature.
