Key Features
- Dual common-cathode configuration with 2 elements in a single TO-220AB package for compact freewheeling diode circuits
- Low forward voltage of 0.92 V maximum for reduced conduction losses and improved power conversion efficiency
- Silicon Schottky rectifier optimized for free-wheeling and efficiency-critical switching power supply applications
Applications
V20202G-M3/4W is ideal for switch-mode power supplies, DC-DC converters, and motor drive circuits where free-wheeling diodes are needed to protect switching transistors from inductive kickback. Its dual common-cathode topology allows a single package to handle two independent diode functions, reducing BOM count in half-bridge and full-bridge rectification stages. The low 0.92 V forward voltage maximizes efficiency in high-current power electronics designs.

Frequently Asked Questions
What is the forward voltage specification of the V20202G-M3/4W, and how does it affect power supply efficiency?
The V20202G-M3/4W has a maximum forward voltage of 0.92 V, which is lower than standard silicon rectifier diodes at equivalent current levels. Lower forward voltage directly reduces conduction losses (P = Vf × If), improving the efficiency of DC-DC converters and switch-mode power supplies, especially at high switching frequencies where diode conduction time is significant.
What package does the V20202G-M3/4W use, and how does its dual-element configuration benefit circuit design?
The device is housed in a TO-220AB package with a common-cathode dual-element configuration containing 2 independent diode elements sharing a single cathode terminal. This allows designers to use both diodes in a full-wave rectifier or freewheeling circuit without needing 2 separate packages, saving PCB space and reducing component count in motor drives and power converters.
For which switching power supply topologies is the V20202G-M3/4W most suitable?
The V20202G-M3/4W is particularly suited for buck, boost, and flyback converter topologies where a freewheeling diode must handle inductive energy stored in inductors or transformer windings. Its dual common-cathode, 2-element design at 0.92 V forward drop makes it efficient in half-bridge rectifiers, synchronous rectification bypass circuits, and DC motor drive freewheeling stages operating up to several hundred kHz.
What lead time and availability should engineers expect for the V20202G-M3/4W?
The V20202G-M3/4W has a factory lead time of approximately 7 weeks from Vishay's production line. Engineers working on new designs should account for this lead time when planning procurement schedules, especially for production builds requiring hundreds or thousands of units. Stocking distributors often carry inventory to provide faster delivery for smaller quantities below 1,000 pieces.
