Overview
The 12CWQ04FN is a 12 Ampere, 40 Volt Fast Recovery Rectifier manufactured by SMC Diode Solutions. It utilizes the Superfast Plus® technology to achieve low forward voltage drop and fast recovery characteristics. The component is housed in a TO-263AB (D2PAK) surface-mount package with three leads. It is designed for high-efficiency power conversion applications requiring robust performance under thermal stress.
Feature Summary
- Superfast Plus® technology ensures low forward voltage drop and fast recovery times.
- High surge current capability provides robustness against transient overload conditions.
- Surface-mount TO-263AB package facilitates automated assembly and efficient PCB layout.
Applications
- DC-to-DC converters
- Power factor correction circuits
- Freewheeling diodes in high-frequency switching supplies
Procurement Notes
Verify the manufacturer marking on the component body matches SMC Diode Solutions branding. Confirm the part number suffix corresponds to the standard tape-and-reel packaging configuration. Ensure the date code aligns with current production standards to avoid obsolete stock.
Selection Notes
Select this component when a 12A continuous current rating and 40V reverse voltage are required in a D2PAK footprint. Consider its thermal resistance characteristics relative to the board copper area. Evaluate if the specific recovery time meets the switching frequency requirements of the target circuit design.
Part Context
This rectifier belongs to SMC Diode Solutions' Superfast Plus® series, which focuses on improving efficiency in power electronics. The series offers alternatives to traditional silicon rectifiers by reducing conduction losses. It serves as a direct replacement for legacy through-hole devices in modern surface-mount designs.
Replacement Considerations
Check pinout compatibility with existing footprints. Verify that the replacement's thermal resistance and peak reverse voltage ratings meet or exceed the original design specifications. Ensure the new component's recovery time does not introduce excessive ringing in the target application.
