Q2012NH5RP

Triacs Overview

The Littelfuse Q2012NH5RP is a bidirectional triac thyristor designed for surface-mount applications. It features an RMS on-state current of 12 A and a rated repetitive peak off-state voltage of 400 V. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. The non-repetitive peak on-state current ratings are specified at 110 A and 120 A. The component utilizes an SMTO-263-2 package with a typical on-state voltage of 1.6 V and a maximum off-state leakage current of 10 uA.

Triacs Feature Summary

• Lighting dimmer systems utilizing surface-mount technology

Triacs Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm availability and specifications. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as indicated in the manufacturer's datasheet. Cross-reference the component details with authorized distributor catalogs to validate authenticity and compliance with relevant standards before procurement.

Triacs Selection Notes

Select this component based on its 400 V blocking voltage and 12 A continuous current rating. Verify that the gate trigger requirements align with the driving circuit capabilities. Consider the thermal management needs associated with the SMTO-263-2 package for the intended operating environment. Confirm that the application voltage and current stresses remain within the specified limits defined in the technical data.

Triacs Part Context

This triac belongs to the Qxx12xHx series from Littelfuse, which provides high-performance thyristors for general-purpose AC switching. The series is characterized by robust surge handling and reliable latching behavior. The Q2012NH5RP variant specifically addresses applications requiring moderate voltage blocking and high current capacity in a surface-mount footprint.

Triacs Replacement Considerations

Potential substitutes within the same family include the Q4012NH5RP and Q6012NH5RP, which share identical current and package specifications but offer higher voltage ratings of 400 V and 600 V respectively. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers.
