VF30120C-M3/4W

Diode Arrays Overview

The VF30120C-M3/4W is a dual high-voltage Trench MOS Barrier Schottky (TMBS) rectifier in an ITO-220AB package. It features a common cathode configuration with two diodes, each rated for 15 A average forward current and a maximum repetitive peak reverse voltage of 120 V. The device supports a peak forward surge current of 150 A and operates within a junction temperature range of -40 °C to +150 °C. Electrical characteristics include a typical instantaneous forward voltage of 0.56 V at 5 A and a maximum reverse current of 800 µA at 120 V.

Diode Arrays Feature Summary

• Utilizes Trench MOS Schottky technology to achieve low forward voltage drop and reduced power losses.
• Provides high efficiency operation suitable for demanding power conversion environments.
• Features matte tin plated leads that are solderable per J-STD-002 standards.

Diode Arrays Applications

• High frequency DC/DC converters
• Switching power supplies
• Freewheeling diodes
• OR-ing diode circuits
• Reverse battery protection

Diode Arrays Procurement Notes

Verify the specific ordering suffix /4W corresponds to the tube packaging format containing 50 units per tube as defined in the manufacturer's ordering information. Confirm compliance requirements such as RoHS and halogen-free status match project specifications. Ensure thermal management designs account for the specified thermal resistance values to maintain safe operating temperatures under load conditions.

Diode Arrays Selection Notes

Select this component when a dual common cathode Schottky rectifier is required for 120 V applications. The ITO-220AB case provides isolation from the heatsink, simplifying mounting compared to standard TO-220 packages. Consider the derating curves for ambient temperatures exceeding 25 °C to ensure the 15 A per diode rating is maintained without exceeding the maximum junction temperature limit.

Diode Arrays Part Context

This part belongs to the VF30120 series of Vishay General Semiconductor dual TMBS rectifiers. It shares the same electrical ratings and pinout as the non-suffixed VF30120C but specifies the /4W suffix for tube delivery. The M3 suffix indicates lead finish and material compliance adjustments compared to older variants.

Diode Arrays Replacement Considerations

Direct functional substitutes within the same family include the VF30120C-E3/4W. Verify package compatibility and electrical parameters before substitution.
