Vishay General Semiconductor - Diodes Division VI40100C-M3/4W

Overview

VI40100C-M3/4W from Vishay General Semiconductor is a dual high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in TO-262AA package, configured as common cathode, rated for 100 V reverse voltage and 2 × 20 A average forward current per diode, with ultra-low 0.38 V forward voltage at 5 A and 125 °C junction temperature - optimized for high-efficiency DC/DC converters and reverse battery protection circuits.

For engineers reviewing the VI40100C-M3/4W datasheet, VI40100C-M3/4W pinout, VI40100C-M3/4W application, or VI40100C-M3/4W equivalent, key selection criteria include its 0.61 V VF at 20 A, 250 A IFSM surge rating, 2.0 °C/W thermal resistance per diode, common-cathode configuration, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.

Technical Context

This dual TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced power losses versus planar Schottky or fast recovery diodes. Its common-cathode topology enables synchronous OR-ing and bidirectional freewheeling paths in compact power stages.

Rated for continuous operation up to 150 °C junction temperature and capable of 10,000 V/μs dV/dt, the VI40100C-M3/4W supports high-frequency switching topologies where low reverse recovery charge and minimal switching loss are critical - especially in 100 kHz–1 MHz DC/DC converters with tight thermal constraints.

FAQ

What is the maximum junction temperature rating for the VI40100C-M3/4W?

The VI40100C-M3/4W has a maximum operating junction temperature (TJ max) of +150 °C, verified per Vishay Document Number 89162. This rating enables reliable operation in sealed enclosures and under-hood environments where ambient temperatures exceed 85 °C. Derating curves in Figure 1 confirm usable current capacity down to 10 A at 125 °C case temperature. The VI40100C-M3/4W must be mounted to a heatsink meeting thermal resistance targets to maintain this limit.

Is the VI40100C-M3/4W pin-compatible with the V40100C-M3/4W?

No, the VI40100C-M3/4W and V40100C-M3/4W are not pin-compatible: VI40100C-M3/4W uses TO-262AA (surface-mount variant), while V40100C-M3/4W uses TO-220AB (through-hole). Pin numbering is identical (Anode1–Cathode–Anode2), but lead pitch, flange isolation, and mounting method differ. PCB redesign is required to substitute one for the other. The VI40100C-M3/4W remains the only option for automated SMT assembly targeting the same electrical specs.

What is the typical forward voltage of the VI40100C-M3/4W at 10 A and 125 °C?

Per Vishay Document Number 89162, the typical forward voltage (VF) of the VI40100C-M3/4W at IF = 10 A and TA = 125 °C is 0.45 V. This value is measured per diode under pulsed conditions and reflects the device's low-loss advantage at elevated temperatures. At the same condition, the maximum VF is 0.51 V. These values are critical for calculating conduction loss in thermally constrained applications such as fanless industrial PSUs.

Does the VI40100C-M3/4W meet RoHS and halogen-free requirements?

Yes, the VI40100C-M3/4W carries the M3 suffix, confirming it is halogen-free, RoHS-compliant, and commercial grade per Vishay's material categorization standard (Document 99912). Lead finish is matte tin, qualified to JESD 201 Class 1A whisker testing, and compliant with J-STD-002 solderability requirements. Full compliance documentation is available via Vishay's online portal using Document Number 89162.

What is the thermal resistance from junction to case (RθJC) for the VI40100C-M3/4W?

The typical thermal resistance from junction to case (RθJC) for the VI40100C-M3/4W is 2.0 °C/W per diode, as specified in the Thermal Characteristics table of Vishay Document Number 89162. This value applies when the device is mounted with proper torque (≤10 in-lbs) to a flat, clean heatsink surface. It enables accurate thermal modeling for power dissipation up to 15 W per diode before exceeding the 150 °C TJ limit.
