Q6010R4

Triacs Overview

The Littelfuse Q6010R4 is a bidirectional triac belonging to the Qxx10xx series, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 10 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger voltage of 2.5 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 an off-state leakage current of 10 µA.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated PCB assembly
• High thermal stability supporting operation up to +125°C junction temperature
• Sensitive gate triggering capability for direct microprocessor interface

Triacs Applications

• Solid-state relays
• Motor speed control circuits
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix 'R4' against the official Littelfuse datasheet to confirm the reel packaging configuration and exact pinout orientation. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements. Cross-reference the component marking code to distinguish this variant from other packages in the Q6010 family.

Triacs Selection Notes

Select the Q6010R4 when a surface-mount solution is required for 10 A AC loads with a 600 V blocking voltage. This part is suitable for designs needing sensitive gate drive characteristics with a maximum holding current of 35 mA. Verify that the SMTO-263-2 footprint matches the target PCB layout constraints.

Triacs Part Context

This component belongs to the Littelfuse Qxx10xx series of high-performance triacs. The series provides robust AC switching capabilities for general-purpose power control. The Q6010R4 specifically offers a surface-mount alternative to through-hole variants like the TO-220-2 package, facilitating compact circuit board designs.

Triacs Replacement Considerations

Direct substitutes include the Q6010N4RP, which shares identical electrical ratings but may differ in specific tape-and-reel specifications. Other compatible options within the same series include the Q6010L4TP for through-hole applications.
