1N5803E3

Overview

The Microchip Technology 1N5803E3 is a silicon Schottky barrier rectifier designed for high-efficiency power conversion applications. This single-configuration device features a Top Hat-2 through-hole package and operates with a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 5 A. The component exhibits a low forward voltage drop of 400 mV at rated current, contributing to reduced power loss and thermal management requirements. It supports a high non-repetitive peak forward surge current of 150 A and maintains reliable operation across a wide temperature range from -65°C to +175°C junction temperature. The reverse leakage current is specified at 10 mA under standard conditions.

Procurement Notes

Verify the complete ordering part number including any specific suffixes that may denote tape-and-reel packaging versus bulk or tray quantities. Confirm RoHS compliance status and lead-free characteristics directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required through-hole mounting style and package dimensions for your printed circuit board layout.

Selection Notes

Select this component when designing circuits that demand low forward voltage drop to maximize efficiency and minimize heat generation. Consider the 5 A continuous current rating and 30 V blocking voltage to ensure adequate headroom for your specific load and input voltage conditions. Evaluate the thermal resistance of the Top Hat-2 package against your system's cooling capabilities to maintain junction temperatures within the specified operational limits during peak loads.
