1N3912

Single Diodes Overview

The Microchip Technology 1N3912 is a silicon rectifier diode designed for high-current applications. It features a single-phase, one-element configuration with a maximum average forward rectified current of 50A and a repetitive peak reverse voltage rating of 300V. The device utilizes a stud mount package (DO-203AB) with the case connected to the anode. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 340A and a junction temperature range from -65°C to 150°C.

Single Diodes Feature Summary

• High current handling capability suitable for power rectification
• Stud mount construction with anode-connected case for thermal management
• Silicon planar epitaxial construction for reliability

Single Diodes Applications

• Industrial power supplies
• Battery charging systems
• Welding equipment rectifiers

Single Diodes Procurement Notes

Verify the specific suffix (e.g., A or R) when ordering, as it may indicate variations in packaging or manufacturing lot. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Ensure the stud mount interface matches the heatsink requirements for adequate thermal dissipation during operation.

Single Diodes Selection Notes

Select this component for circuits requiring robust 50A continuous current handling at 300V blocking voltage. The stud mount package is ideal for high-power density designs where efficient heat transfer to a chassis or heatsink is critical. Consider the forward voltage drop and thermal resistance when designing the cooling system for sustained load conditions.
