1N5818-AP

Overview

The MCC 1N5818-AP is a silicon Schottky rectifier with a 30 V maximum repetitive reverse voltage and a 1 A average forward current rating. It utilizes the DO-41 axial package for through-hole mounting. The device features a low forward voltage drop of 0.50 V at 1 A and a junction-to-lead thermal resistance of 25 °C/W. Electrical characteristics include a maximum reverse leakage current of 1 mA at rated voltage and a typical reverse recovery time of 10 ns.

Feature Summary

• Metal silicon junction construction utilizing majority carrier conduction
• Guard ring design provides protection against overvoltage conditions
• Epoxy casing meets UL 94 V-0 flammability classification standards

Applications

• Low voltage high frequency inverters
• Free wheeling diode circuits
• Polarity protection applications
• Small battery chargers

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the -AP suffix corresponds to the specified Ammo Box packing configuration containing 5,000 pieces per unit. Ensure compliance with RoHS directives if lead-free finish requirements are necessary for the assembly process.

Selection Notes

Select this component when a 30 V blocking capability is required alongside a 1 A continuous current rating in an axial package. The Schottky technology offers lower power loss compared to standard silicon rectifiers. Verify that the operating junction temperature range of -55°C to 125°C aligns with the thermal environment of the target circuit design.

Part Context

This part belongs to the 1N5817 through 1N5819 series of axial power Schottky rectifiers manufactured by Micro Commercial Components. These devices share identical physical dimensions and general electrical structures, differing primarily in their peak repetitive reverse voltage ratings which range from 20 V to 40 V within the series lineup.

Replacement Considerations

Compatible substitutes include the 1N5818 from STMicroelectronics and the SR103 B0G from Taiwan Semiconductor Corporation.
