Product details
Overview
V40D100C-M3/I from Vishay General Semiconductor is a dual common-cathode Trench MOS Barrier Schottky (TMBS®) rectifier in SMPD (TO-263AC) package, rated for 100 V reverse voltage, 40 A total average forward current (2 × 20 A per diode), and 0.40 V forward voltage at 5 A/125 °C - optimized for high-efficiency DC/DC converters and reverse battery protection in automotive and industrial power systems.
For engineers reviewing the V40D100C-M3/I datasheet, V40D100C-M3/I pinout, V40D100C-M3/I application, or V40D100C-M3/I equivalent, key selection criteria include its ultra-low VF (0.40 V @ 5 A/125 °C), AEC-Q101-qualified variant availability (V40D100CHM3/I), MSL Level 1 reflow compatibility, and SMPD thermal performance (RθJA = 45 °C/W).
Technical Context
This dual TMBS® rectifier uses trench MOS barrier technology to achieve significantly lower forward voltage than planar Schottky or fast recovery diodes, enabling higher efficiency in high-frequency switching topologies. Its common-cathode configuration supports OR-ing and freewheeling functions with shared cathode routing.
Thermally, it features low junction-to-case resistance (RθJC = 1.0 °C/W per device) and is qualified for operation from –40 °C to +150 °C junction temperature, with robust surge capability (IFSM = 250 A, 10 ms half-sine) and dV/dt rating of 10,000 V/μs - critical for noise-immune operation in buck converters and synchronous rectifier auxiliary paths.
Key Specifications

Applications
| Automotive Reverse Battery Protection | High-Frequency DC/DC Converter Freewheeling |
|---|---|
Use Scenario: Prevents damage to 12 V/24 V vehicle ECUs during incorrect battery connection or jump-start events. IC Role / Device Role / Timing Role: Dual-anode configuration allows single-device protection across two independent power domains (e.g., infotainment + ADAS rail). Use Value: 0.40 V VF at 125 °C limits power dissipation to <2.5 W at 5 A - avoids thermal shutdown in confined under-dash enclosures. | Use Scenario: Freewheeling path in 300 kHz–1 MHz buck converter for server VRMs or telecom POL supplies. IC Role / Device Role / Timing Role: Low VF and fast recovery (<50 ns) minimize dead-time losses and improve light-load efficiency. Use Value: 250 A IFSM rating handles transient overloads without degradation - extends reliability beyond 10⁶ cycles. |
| OR-ing Diode for Redundant Power Supplies | Industrial Switching Power Supply Output Rectification |
Use Scenario: Enables seamless switchover between two AC/DC front-ends in telecom shelf power systems. IC Role / Device Role / Timing Role: Common-cathode topology provides matched thermal coupling and voltage drop between parallel inputs. Use Value: 20 A per diode rating supports ≥40 A combined output with <1.5 mV mismatch - ensures balanced current sharing. | Use Scenario: Secondary-side rectification in 48 V input industrial SMPS delivering 12 V/20 A output. IC Role / Device Role / Timing Role: Replaces fast recovery diodes to reduce conduction loss and EMI generation at 100–500 kHz switching frequencies. Use Value: RθJA = 45 °C/W allows full 40 A rating on 4-layer PCB with 7 cm² thermal pad - eliminates need for heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V40D100CHM3/I | AEC-Q101 qualified; identical electrical specs; same SMPD package; HM3 suffix denotes automotive qualification | Required for automotive production; supports PPAP documentation and extended temperature validation | Select V40D100CHM3/I when automotive qualification, traceability, or long-term supply assurance is mandatory |
| STPS40H100CG-TR | 100 V, 40 A dual common-cathode Schottky; VF = 0.65 V @ 20 A/125 °C; TO-263AB package; no AEC-Q101 option | Higher VF increases conduction loss by ~0.5 W at 20 A; same footprint but different thermal pad layout | Consider STPS40H100CG-TR only if Vishay supply constraints exist and 0.25 V higher VF is acceptable in thermal budget |
Compared with V40D100C-M3/I, the V40D100CHM3/I offers identical performance with added automotive qualification, while STPS40H100CG-TR delivers comparable current handling but at higher forward loss and without automotive validation - making V40D100C-M3/I optimal for cost-sensitive industrial and commercial designs requiring best-in-class VF.

FAQ
What is the maximum junction temperature rating for the V40D100C-M3/I?
The V40D100C-M3/I has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay Document Number 87950. This rating allows continuous operation in under-hood automotive environments and high-ambient industrial settings without thermal derating below 125 °C ambient, provided PCB thermal design meets RθJA ≤ 45 °C/W.
Is the V40D100C-M3/I pin-compatible with the V40D100CHM3/I?
Yes, the V40D100C-M3/I and V40D100CHM3/I share identical SMPD (TO-263AC) package dimensions, pinout, and mechanical footprint - differing only in qualification level (commercial vs. AEC-Q101). No PCB redesign is needed when upgrading to the HM3 variant for automotive use.
What is the forward voltage of the V40D100C-M3/I at 20 A and 125 °C?
The V40D100C-M3/I exhibits a typical forward voltage of 0.63 V at 20 A and 125 °C, with a maximum of 0.69 V per diode, as specified in the Electrical Characteristics table of Vishay Document Number 87950. This value is measured under pulsed conditions with ≤5 ms pulse width.
Does the V40D100C-M3/I meet RoHS and halogen-free requirements?
Yes, the V40D100C-M3/I is halogen-free and RoHS-compliant per EU Directive 2011/65/EU, with material compliance documented in Vishay's "Material Categorization" reference (www.vishay.com/doc?99912). The "M3" suffix explicitly denotes this environmental compliance.
What is the thermal resistance from junction to ambient for the V40D100C-M3/I?
The typical junction-to-ambient thermal resistance (RθJA) for the V40D100C-M3/I is 45 °C/W under standard test conditions (free air, no heatsink, FR4 PCB with unspecified copper area). Actual RθJA improves significantly with increased copper pad area - down to ~35 °C/W with 7 cm² of 70 μm copper, per Figure 7 in the datasheet.
