Overview
The Microchip Technology 1N5832 is a silicon Schottky rectifier diode designed for high-current applications. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current rating of 40 A. The device utilizes a DO-203AB (DO-5) base-mount package with stud installation, suitable for robust power environments. Key electrical characteristics include a forward voltage of 520 mV at 40 A and a maximum reverse leakage current of 20 mA at 10 V. The junction temperature range spans from -65°C to 150°C.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and fast switching performance.
- High current handling capability rated at 40 A average forward rectified current.
- Robust mechanical construction with base and stud mounting options in the DO-5 package.
Applications
- General purpose rectification in power supply circuits
- Free-wheeling diodes in inductive load protection
- Reverse polarity protection in high-current DC systems
Procurement Notes
Verify the manufacturer designation on official datasheets, as multiple vendors produce this standard part number. Confirm that the specific unit meets the required thermal and electrical specifications for your application. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the package type matches your mounting requirements.
Selection Notes
Select this component when a low-loss, high-current rectifier is needed for 20 V systems. The DO-5 package requires appropriate heatsinking and mechanical mounting hardware. Compare forward voltage and leakage current specifications against alternative Schottky diodes to ensure optimal efficiency for the specific load conditions.
Part Context
This component belongs to the standard 1N58xx series of Schottky rectifiers. It is widely used in industrial and automotive power electronics where reliability under high current stress is critical. The DO-5 package provides a balance between high current capacity and manageable physical size for panel or chassis mounting.
Replacement Considerations
Cross-reference with other manufacturers' 1N5832 equivalents such as those from Central Semiconductor or GeneSiC. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement part meets or exceeds the 40 A current and 20 V voltage ratings.
