1N4245US

Single Diodes Overview

The Microchip Technology 1N4245US is a single standard recovery rectifier diode designed for surface-mount applications. It features a maximum repetitive reverse voltage of 200 V and an average forward rectified current of 1 A. The device utilizes a MELF (Metal Electrode Leadless Face) package, specifically SQ SMT configuration. Key electrical characteristics include a maximum forward voltage of 1.3 V at rated current and a maximum reverse leakage current of 1 µA at 200 V. The component supports a maximum surge current of 25 A and exhibits a typical reverse recovery time of 5 µs. It operates within a junction temperature range of -65°C to 175°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure the selected variant matches the required surface-mount footprint and thermal management needs. Confirm compliance with RoHS directives if applicable to the target assembly process. Cross-reference datasheet parameters against circuit requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a robust surface-mount rectifier with high-temperature tolerance is required. The 200 V rating provides sufficient margin for many low-voltage DC applications. Consider the 5 µs recovery time for frequency limitations in switching applications. Evaluate thermal dissipation capabilities based on the MELF package's thermal resistance characteristics.

Single Diodes Part Context

The 1N4245US belongs to Microchip's discrete diode portfolio, offering a surface-mount alternative to traditional through-hole rectifiers. It shares functional similarities with other 1N424x series devices but differs in packaging and potentially detailed electrical tolerances. This part is engineered for reliability in industrial and commercial electronics requiring compact form factors.

Single Diodes Replacement Considerations

Direct replacements must match the 200 V reverse voltage, 1 A forward current, and MELF SQ SMT package. Verify that substitute components meet or exceed the 175°C operating temperature limit and 5 µs reverse recovery time specifications to ensure circuit compatibility.
