1N5817-AP

Overview

The MCC 1N5817-AP is a Schottky barrier rectifier housed in the DO-41 axial package. It features a maximum repetitive peak reverse voltage of 20 V and an average rectified forward current rating of 1 A. The device exhibits a low forward voltage drop, with a maximum value of 0.60 V at 1 A and 25°C. It supports a non-repetitive peak surge current of 30 A under standard half-sine wave conditions. The component operates within a junction temperature range of -55°C to 125°C.

Feature Summary

• Utilizes metal-semiconductor junction technology for high efficiency and low power loss
• Incorporates guard ring protection to enhance stability
• Epoxy material meets UL 94 V-0 flammability rating
• Features extremely fast switching characteristics with negligible switching losses

Applications

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

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack warranty coverage. Confirm the specific AP suffix indicates Ammo Packing containing 5000 pieces per box. Ensure compliance with RoHS standards if required for the application environment.

Selection Notes

Select this component for low voltage DC-DC conversion where minimal conduction loss is critical. The DO-41 through-hole package suits general-purpose circuit boards. Consider the 20 V reverse voltage limit carefully against peak line transients. The 1 A continuous current rating defines the thermal management requirements for the specific enclosure design.

Part Context

This part belongs to the 1N5817 series of axial power Schottky rectifiers manufactured by Micro Commercial Components. The series includes variants with different voltage ratings, specifically 1N5817 (20V), 1N5818 (30V), and 1N5819 (40V). All share identical current ratings and physical dimensions within the DO-41 package family.

Replacement Considerations

Cross-reference with other manufacturers' 1N5817 equivalents such as those from onsemi or LGE. Verify that substitute components maintain the same DO-41 footprint and meet the 20 V / 1 A electrical specifications. Check for identical thermal resistance values to ensure compatibility with existing heat dissipation designs.
