VS-12F100M

Single Diodes Overview

The VS-12F100M is a standard recovery rectifier diode from the Vishay VS-12F series, designed for high-voltage applications. It features a peak repetitive reverse voltage (Vrrm) of 1 kV and a maximum continuous forward current (If) of 12 A. The device utilizes a stud cathode configuration within a DO-203AA package, suitable for screw terminal mounting. Key electrical characteristics include a peak non-repetitive forward surge current (Ifsm) of 280 A, a maximum forward voltage (Vf) of 1.26 V, and a peak reverse current (Ir) of 12 mA. It operates reliably across a temperature range from -65°C to +175°C.

Single Diodes Feature Summary

• High voltage capability with 1 kV peak repetitive reverse voltage rating
• Robust thermal performance supporting operation up to 175°C junction temperature
• Stud cathode design optimized for efficient heat dissipation via screw terminal mounting
• Standard recovery characteristics suitable for general-purpose rectification

Single Diodes Applications

• Industrial power supplies requiring high voltage isolation
• Motor drive circuits and inverter systems
• Welding equipment power stages
• Uninterruptible power supply (UPS) rectification

Single Diodes Procurement Notes

Verify the specific suffix 'M' against official Vishay documentation to confirm if it denotes a specific marking code or variant distinct from the base VS-12F100. Ensure the procurement specification matches the required stud mounting hardware and torque specifications for the DO-203AA package. Confirm RoHS compliance status through the manufacturer's latest datasheet or compliance declaration, as packaging variations may exist.

Single Diodes Selection Notes

Select this component when a single-phase or bridge rectifier application demands a 1 kV blocking voltage and 12 A continuous current capacity. The stud cathode package is preferred over axial leads for higher power density and better thermal management in chassis-mounted designs. Consider the 1.26 V forward voltage drop for efficiency calculations at rated load. Ensure the circuit can handle the 280 A surge current without exceeding the device's limits.

Single Diodes Part Context

The VS-12F100M belongs to the VS-12F family of standard recovery diodes manufactured by Vishay General Semiconductor. This series is engineered for robustness in demanding power electronics environments. The DO-203AA package provides a standardized footprint for industrial power modules. The 'VS' prefix typically indicates Vishay Semiconductors, while '12F' denotes the 12 Ampere current class within the standard recovery lineup.
