Overview
The SMC Diode Solutions 120NQ045R-1 is a single Schottky diode housed in the PRM1-1 chassis mount package. It features a maximum DC reverse voltage of 45 V and an average forward current rating of 120 A. The device supports a non-repetitive peak forward surge current of 1.86 kA. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Utilizes Schottky technology for low forward voltage drop characteristics
- Designed for chassis mounting via the PRM1-1 half-pak module form factor
- Capable of handling high surge currents up to 1.86 kA
Applications
- DC-DC converter circuits
- Free-wheeling rectification in power supplies
- High-current low-voltage rectification applications
Procurement Notes
Verify the specific suffix '-1' against your schematic, as it denotes the PRM1-1 package variant. Confirm RoHS compliance status with the supplier prior to ordering. Check lead times carefully as this item may not be kept in standard stock by all distributors. Ensure thermal management solutions match the chassis mount requirements.
Selection Notes
Select this component when a 45 V reverse voltage rating and 120 A continuous current are required in a compact chassis-mount format. The Schottky construction offers efficiency advantages over standard PN junctions. Verify that the PCB or heatsink interface matches the PRM1-1 mechanical dimensions. Consider the 1.86 kA surge capability for inrush protection needs.
Part Context
This part belongs to the 120NQ series of single Schottky diodes from SMC Diode Solutions. It is functionally related to the 120NQ035 and 120NQ060 variants, which share similar current ratings but differ in reverse voltage specifications. The PRM1-1 package is common across several models in this product line for standardized mounting.
Replacement Considerations
The 120NQ045R-1 and 121NQ045R-1 are confirmed substitutes that satisfy electrical and mechanical equivalence criteria. Both are manufactured by SMC Diode Solutions. Verify pinout compatibility and thermal resistance values before final substitution.
