DSB5820

Single Diodes Overview

The DSB5820 is a hermetically sealed Schottky barrier rectifier manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 20 V and an average rectified forward current rating of 3.0 A at a lead temperature of +55°C. The device exhibits a maximum forward voltage of 0.40 V at 1.0 A and a maximum reverse leakage current of 0.10 mA at rated voltage and +25°C. Thermal resistance from junction to case is limited to 30 °C/W, with an operating temperature range spanning -65°C to +125°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm exact qualification levels and testing requirements. Ensure that the component meets the necessary environmental standards for the intended application. Confirm availability through authorized distribution channels as supply chain constraints may affect delivery schedules.

Single Diodes Selection Notes

Select this component when a 20 V reverse voltage rating and 3.0 A continuous current capacity are required in a ruggedized package. Consider the thermal resistance limits and derating curves above +55°C during circuit design. Verify compatibility with existing lead materials and mounting positions within the system architecture.

Single Diodes Part Context

This part belongs to the DSB58xx series of Schottky barrier rectifiers designed for demanding applications. It shares physical characteristics with the 1N5822 and DSB3A20 variants but is distinguished by its specific 20 V breakdown voltage rating. The series utilizes a hermetic 'B' body package suitable for rigorous operational environments.

Single Diodes Replacement Considerations

Direct equivalents include the 1N5822 and DSB3A20, which share identical electrical ratings and package dimensions. Substitutions must maintain the same voltage and current capabilities while adhering to the hermetic sealing requirements.
