The MDD 1N5399 is an axial lead general purpose silicon rectifier in the DO-15 series. It features a maximum repetitive peak reverse voltage of 1000V and a maximum average forward output rectified current of 1.5A at 75°C. The device supports a peak forward surge current of 50.0A for an 8.3ms single half sine-wave. Operating junction temperature ranges from -50°C to +150°C, with a storage temperature range of -50°C to +150°C.
Verify the specific manufacturer designation when sourcing this component, as multiple vendors produce the 1N5399 standard. Confirm compliance with RoHS/RoHS III requirements if applicable to your assembly process. Ensure the packaging format matches your handling equipment, such as AMMO packs or tape and box configurations. Cross-reference part numbers carefully to ensure electrical parameters align with your design specifications.
Select this rectifier for applications requiring high reverse voltage blocking up to 1000V and moderate continuous current handling. The DO-15 package provides robust mechanical stability for through-hole mounting. Consider the thermal resistance characteristics and derating requirements for capacitive loads during circuit design. Verify that the operating temperature range meets the environmental conditions of the intended application.
This component belongs to the DO-15 series of general purpose silicon rectifiers. It is designed for standard rectification tasks where high reliability and surge capability are required.
