Overview
The Microchip Technology 1N6662US is a standard recovery rectifier designed for surface-mount applications. It features a single diode configuration housed in a D-5A-2 package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward current of 500 mA. Key electrical characteristics include a maximum forward voltage of 1 V at the rated current, a maximum surge current capability of 5 A, and a low reverse leakage current of 50 nA. It operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Standard recovery rectifier technology optimized for general-purpose switching applications
- High thermal stability with a maximum operating junction temperature of +175°C
- Surface-mount construction in a compact D-5A-2 package for automated assembly
Applications
- General-purpose power supply rectification
- DC-to-DC converter output stages
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm RoHS status as non-compliant based on available documentation. Ensure design compatibility with the D-5A-2 footprint and verify that the 400V rating meets circuit requirements. Check lead times as production cycles may vary.
Selection Notes
Select this component for designs requiring a robust standard recovery diode with high-temperature tolerance. Compare against alternatives if lower forward voltage drop or faster switching speeds are required. Ensure the 500mA current rating aligns with the continuous load expectations of the target application circuit.
Part Context
This part belongs to the 1N66xx series of hermetically sealed or surface-mount rectifiers manufactured by Microchip Technology. The series provides various voltage and current ratings for different power management needs. The US suffix typically denotes a specific surface-mount MELF-style package variant suitable for modern PCB layouts.
Replacement Considerations
Consult official substitution guides for equivalent parts within the same voltage and current class. Verify pinout compatibility with the D-5A-2 package before replacing. Cross-reference specifications for reverse leakage and recovery time to ensure functional parity.
