1N4051

Single Diodes Overview

The Microchip Technology 1N4051 is a silicon planar power rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 1.0 A at an ambient temperature of 75°C and a peak repetitive reverse voltage rating of 50 V. The device utilizes a DO-201AD axial leaded package, providing robust mechanical stability for through-hole mounting. Key electrical characteristics include a maximum RMS rectifying voltage of 35 V and a non-repetitive peak forward surge current capability of 30 A under specified conditions. The component operates within a junction temperature range of -65°C to +175°C, ensuring reliability in demanding thermal environments.

Single Diodes Feature Summary

• High thermal stability with a wide operating junction temperature range extending up to 175°C

• Standardized axial leaded package design for reliable through-hole integration

Single Diodes Applications

• General-purpose power supply rectification circuits
• Bridge rectifier configurations in AC-to-DC conversion systems
• Protection against reverse polarity in DC power inputs

Single Diodes Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the physical markings on the DO-201AD package match the ordered part number exactly. Check for any shipping damage to the leads before soldering. Ensure storage conditions remain within specified limits to prevent oxidation or degradation prior to assembly.

Single Diodes Selection Notes

Select this component when a standard 1A rectifier with a 50V reverse voltage rating is required. Consider the thermal derating curves if the operating ambient temperature exceeds 75°C. Evaluate the PCB layout to accommodate the axial lead spacing of the DO-201AD package. Compare surge current requirements against the 30A specification to ensure adequate safety margins for inductive loads.

Single Diodes Part Context

The 1N4051 belongs to the widely recognized 1N400x series of silicon power rectifiers, established as an industry standard for low-frequency power applications. This series offers consistent performance across various manufacturers, facilitating easy sourcing and replacement. The device serves as a fundamental building block in electronic designs requiring basic power conversion and isolation functions.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N4005 from other manufacturers, provided they meet the same 1A current and 50V voltage ratings. Verify pinout compatibility and package dimensions (DO-201AD) to ensure direct fitment without PCB modifications.
