Overview
The 124NQ040-1 is a Schottky rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current rating of 120 A. The device utilizes the PRM1-1 package, which is a half-pak configuration designed for high-current applications. Key electrical characteristics include a maximum forward voltage drop specified at rated current conditions.
Feature Summary
- Schottky barrier technology for low forward voltage drop
- High current handling capability in compact half-pak package
- Designed for efficient power conversion applications
Applications
- DC-DC converters
- Free-wheeling diodes in inductive loads
- Power supply rectification
Procurement Notes
Verify the specific datasheet revision to confirm thermal resistance values and pinout configurations before integration. Ensure that the PRM1-1 package footprint matches the PCB design requirements. Confirm RoHS3 compliance status if required by project specifications. Cross-reference with official SMC Diode Solutions documentation for accurate mechanical dimensions.
Selection Notes
Select this component when a 40 V reverse voltage rating and 120 A continuous current capacity are required. The Schottky type offers lower switching losses compared to standard PN junction diodes. Consider the thermal management capabilities of the PRM1-1 package for heat dissipation needs in high-power density designs.
Part Context
This part belongs to the 124NQ series of Schottky rectifiers from SMC Diode Solutions. It shares similar electrical ratings with variants like 120NQ040-1 and 121NQ040-1, differing primarily in specific manufacturing batches or minor parameter tolerances within the same product family line.
Replacement Considerations
Verified substitutes include 120NQ040-1, 121NQ040-1, and 124NQ040-1 from SMC Diode Solutions. These parts share matching Vr, Io, and HALF-PAK packaging specifications.
