S12M

Single Diodes Overview

The S12M is a silicon standard recovery diode in the DO-4 (DO-203AA) stud package. It features a repetitive peak reverse voltage of 800 V and a continuous forward current rating of 12 A. The device exhibits a maximum forward voltage of 1.1 V at 12 A and 25 °C, with a thermal resistance from junction to case of 2.50 °C/W. Operating temperature ranges from -55 °C to +150 °C.

Single Diodes Feature Summary

• High surge capability for transient load handling
• Not sensitive to electrostatic discharge

Single Diodes Applications

• Industrial power supplies
• Motor drive rectification
• General-purpose high-voltage rectification

Single Diodes Procurement Notes

Verify the specific suffix against the datasheet table to confirm the exact voltage rating, as the S12 series spans multiple voltage classes. Confirm terminal configuration requirements, noting that standard polarity designates the stud as the cathode while reversed polarity variants exist. Ensure mounting hardware compatibility with the 10-32 UNF thread specification.

Single Diodes Selection Notes

Select this component for applications requiring robust standard recovery characteristics in a stud-mount form factor. Evaluate thermal management needs based on the 2.50 °C/W junction-to-case resistance. Consider the 280 A non-repetitive surge current rating for circuit protection coordination. Verify that the 12 A continuous current rating aligns with the system's steady-state thermal profile.

Single Diodes Part Context

This part belongs to the S12K through S12QR product family, which includes various voltage ratings within the same physical package. The manufacturer utilizes a consistent naming convention where the base model indicates the current rating and package type, while suffixes define voltage and polarity variations.

Single Diodes FAQ

What is the default polarity configuration for the S12M?

The standard polarity configuration designates the stud terminal as the cathode.

How does the thermal resistance affect operation?

The junction-to-case thermal resistance is specified at 2.50 °C/W, requiring adequate heatsinking to maintain the junction temperature within the -55 °C to +150 °C operating range.
