Q2010RH5

Triacs Overview

The Littelfuse Q2010RH5 is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 10 A RMS on-state current and supports a rated repetitive off-state voltage of 200 V. The device operates within a junction temperature range of -40 °C to +125 °C, ensuring reliability in demanding environments. Packaged in a TO-220AB-3 through-hole housing, it offers a typical on-state voltage of 1.6 V and a maximum holding current of 50 mA. Key electrical characteristics include a gate trigger voltage of 1.3 V and a non-repetitive peak on-state current capability of 110 A or 120 A depending on the specific datasheet variant.

Triacs Feature Summary

• High-temperature operation capability up to 125 °C for enhanced thermal stability
• Robust construction with a TO-220AB-3 package for efficient heat dissipation
• Designed for reliable AC power switching in industrial and consumer applications

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays and contactors
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the exact datasheet revision when ordering, as parameters like non-repetitive peak current may vary between 110 A and 120 A variants. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the TO-220AB-3 package matches your PCB footprint requirements before finalizing procurement.

Triacs Selection Notes

Select this component for applications requiring 200 V blocking voltage and 10 A continuous current handling. Consider the 1.6 V on-state voltage for power loss calculations. Verify that the gate trigger current of 50 mA aligns with your driving circuit capabilities. Ensure the operating temperature range meets your system's environmental constraints.

Triacs Part Context

This part belongs to the Qxx10xH series of high-temperature TRIACs from Littelfuse. It shares the same physical package and general current rating with other members like the QJ6010RH5TP but differs in its voltage rating. The 'H' suffix typically denotes high-temperature capability, while 'RH5' indicates the specific pin configuration and packaging style.

Triacs Replacement Considerations

Direct replacements must match the 200 V rating and 10 A current capacity. Check equivalent parts from other manufacturers such as STMicroelectronics or ON Semiconductor that offer similar TO-220AB TRIACs with comparable gate trigger specifications.
