Q6012RH5

Triacs Overview

The Littelfuse Q6012RH5TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 600 V rated repetitive off-state voltage and conducts an RMS on-state current of 12 A. The device utilizes a TO-220AB-3 package for through-hole mounting, ensuring reliable thermal dissipation. Key electrical characteristics include a maximum holding current of 50 mA and a gate trigger current of 50 mA. It operates within a temperature range from -40 °C to +125 °C, providing stable performance in demanding environments.

Triacs Feature Summary

• High-temperature Alternistor design for enhanced reliability
• Robust TO-220AB-3 through-hole packaging
• Capable of handling 12 A RMS on-state current

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay (SSR) modules
• General purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact pinout and thermal specifications. Ensure the procurement channel provides valid manufacturer traceability. Confirm RoHS compliance status directly with the supplier prior to ordering to meet regulatory requirements.

Triacs Selection Notes

Select this component when a 12 A load capacity at 600 V is required in a standard through-hole configuration. Verify that the gate drive circuit can supply the specified 50 mA trigger current. Consider the TO-220AB-3 footprint constraints during PCB layout planning.

Triacs Part Context

This part belongs to the Qxx12xHx series of high-temperature TRIACs manufactured by Littelfuse. These devices are engineered to replace traditional silicon-controlled rectifiers in AC power applications requiring higher thermal stability and ruggedness compared to standard triacs.

Triacs Replacement Considerations

The Q6012LH5TP is a verified substitute within the same family. Both share identical 12 A and 600 V ratings. Verify pin compatibility before substitution.
