SF53-AP

Single Diodes Overview

The SF53-AP is a general-purpose rectifier diode manufactured by Micro Commercial Components (MCC). It features a maximum average forward rectified current of 5.0 A and a peak repetitive reverse voltage rating ranging from 50 V to 600 V, with the specific SF53 variant rated at 150 V. The device utilizes a Glass Passivated Chip construction for enhanced reliability and is housed in a DO-201AD (DO-4) axial leaded package. It is designed for use in various power supply and freewheeling applications requiring standard recovery characteristics.

Single Diodes Feature Summary

• Glass passivated chip construction provides high reliability and resistance to mechanical stress
• High surge current capability for robust performance under transient conditions
• Low forward voltage drop contributes to improved system efficiency
• Equipped with an oxide passivation layer around the glass passivated junction

Single Diodes Applications

• General purpose rectification in AC/DC converters
• Freewheeling diodes in inductive load circuits
• Polarity protection circuits
• Bypass diodes in battery backup systems

Single Diodes Procurement Notes

Verify the exact suffix designation, as MCC offers variants such as SF53-TP and SF53-AP which may differ in packaging or specific testing criteria. Confirm that the component meets RoHS compliance requirements if mandated by your assembly process. Ensure the selected part number matches the required voltage rating within the 50V to 600V range specified for the SF series.

Single Diodes Selection Notes

Select this component when a 5A current capacity and 150V reverse voltage are required in an axial leaded package. Consider the standard recovery time for general switching applications rather than high-frequency switching. Evaluate the thermal management needs based on the DO-201AD package's thermal resistance characteristics and the expected ambient operating temperature range.

Single Diodes Part Context

The SF53-AP belongs to the SF series of super fast rectifiers produced by Micro Commercial Components. This series encompasses multiple voltage ratings from 50V to 600V, all sharing the same 5.0A current handling capability. The SF53 specifically denotes the 150V variant within this lineup, utilizing a standardized DO-201AD package common across the family for easy integration into existing designs.

Single Diodes Replacement Considerations

Direct replacements include other 5A 150V general-purpose diodes in the DO-201AD package, such as the 1N5408 series equivalents. Verify that substitute components maintain similar forward voltage drop and reverse leakage current specifications to ensure circuit compatibility.
