Q2010N5RP

Triacs Overview

The Littelfuse Q2010N5RP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current of 10 A and a rated repetitive peak off-state voltage (VDRM) of 200 V. 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 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. The component exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 100 A or 120 A.

Triacs Feature Summary

• High thermal stability with a maximum operating junction temperature of +125°C
• Surface-mount construction in an SMTO-263-2 package for automated assembly
• Robust switching performance with a 10 A RMS on-state current rating

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse before finalizing procurement. Confirm that the SMTO-263-2 footprint matches the target PCB layout requirements. Ensure that the 200 V voltage rating aligns with the system's peak line voltage specifications to prevent overvoltage failure during operation.

Triacs Selection Notes

Select this component when a 200 V blocking voltage is sufficient for the application, offering a cost-effective alternative to higher-rated variants like the Q4010 or Q8010 series. Verify that the 50 mA gate drive capability is compatible with the available microcontroller or driver output levels. Consider the thermal resistance of the SMTO-263-2 package to ensure adequate heat dissipation under continuous 10 A load conditions.

Triacs Part Context

This part belongs to the Qxx10xx series of high-reliability triacs manufactured by Littelfuse. The series provides standardized pinouts and mechanical dimensions across different voltage ratings, facilitating design scalability. The Q2010N5RP serves as the lowest voltage option in this specific 10 A family, complementing parts such as the Q4010N5RP and Q6010N5RP.

Triacs Replacement Considerations

Direct replacements include other Q2010xx variants from Littelfuse with differing suffixes indicating packaging or compliance changes. Cross-brand equivalents must be verified for identical pinout compatibility and matching electrical parameters, specifically the 200 V VDRM and 10 A It(RMS) ratings.
