V4P22CHM3_A/I

Diode Arrays Overview

The V4P22CHM3_A/I is a common cathode Schottky rectifier diode array manufactured by Vishay General Semiconductor - Diodes Division. It utilizes TMBS (Trench MOS Barrier Schottky) technology to deliver high efficiency and low forward voltage drop. The device is rated for a maximum repetitive reverse voltage of 200V and an average forward current of 4A per diode. It features a low characteristic junction capacitance and is housed in a surface-mount SOT-323 package, designed for high-speed switching applications with minimal power loss.

Diode Arrays Feature Summary

• Utilizes Trench MOS Barrier Schottky (TMBS) technology for superior performance
• Low forward voltage drop reduces conduction losses
• High switching efficiency with low reverse recovery charge
• Common cathode configuration simplifies circuit design

Diode Arrays Applications

• DC-DC converters
• Free-wheeling diodes in inductive loads
• Power supply rectification
• Reverse polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix A/I against the official Vishay datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the component meets RoHS directives if required by your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm thermal management requirements based on the SOT-323 package limitations during operation.

Diode Arrays Selection Notes

Select this component when a compact solution for low-voltage, high-frequency rectification is needed. The 200V rating provides sufficient headroom for 12V or 24V systems. Consider the 4A current capacity relative to thermal dissipation constraints in the SOT-323 package. Compare junction capacitance values against other Schottky arrays if signal integrity is critical in high-speed digital interfaces.

Diode Arrays Part Context

This part belongs to Vishay's TMBS diode array family, which combines the benefits of Schottky barriers with trench MOS technology. It is designed as a space-saving alternative to discrete diodes in dual configurations. The common cathode arrangement allows for efficient use in bridge-less PFC or synchronous rectification topologies where size and weight are constrained.

Diode Arrays Replacement Considerations

Check for direct equivalents such as the VS-V4P22C-M3/H series from the same manufacturer. Verify that any substitute maintains the 200V reverse voltage and 4A current ratings. Ensure the replacement package matches the SOT-323 footprint for board compatibility. Confirm that the alternative shares the same low forward voltage characteristics to maintain system efficiency.
