Product details
Overview
VB30100SG-M3/4W from Vishay General Semiconductor is a high-voltage trench MOS barrier Schottky rectifier in D2PAK (TO-263AB) package, rated for 100 V repetitive peak reverse voltage, 30 A average forward current, and 0.76 V forward voltage at 30 A and 25 °C. It serves as a low-loss freewheeling or OR-ing diode in high-frequency DC/DC converters and reverse battery protection circuits.
For engineers reviewing the VB30100SG-M3/4W datasheet, VB30100SG-M3/4W pinout, VB30100SG-M3/4W application, or VB30100SG-M3/4W equivalent, key selection criteria include its ultra-low VF at high current, 150 °C max junction temperature, 2.0 °C/W thermal resistance, and MSL Level 1 moisture sensitivity rating for lead-free reflow compatibility.
Technical Context
This device uses trench MOS Schottky technology to achieve lower forward voltage and higher efficiency than planar Schottky or standard PN rectifiers. Its 100 V VRRM and 250 A IFSM surge rating support robust operation in switching power supplies with transient overloads.
The D2PAK package provides low thermal resistance (RθJC = 2.0 °C/W) and a heatsink-compatible exposed cathode tab. Polarity is marked on the case, with terminals matte tin plated per J-STD-002 and JESD 22-B102, and M3 suffix confirming JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rails up to 70 V DC with safety margin in industrial and automotive DC/DC stages |
| IF(AV) | 30 A - continuous conduction capability for high-power 12 V or 24 V output converters |
| VF @ 30 A, 25 °C | 0.76 V - reduces conduction loss to ~22.8 W, enabling higher efficiency vs. silicon diodes |
| RθJC | 2.0 °C/W - allows direct heatsink mounting to sustain full current at TJ ≤ 150 °C |
| TJ max. | 150 °C - enables operation in under-hood or enclosed industrial environments without derating |
| dV/dt | 10,000 V/μs - withstands fast-switching transients in synchronous rectifier and LLC resonant topologies |
| IR @ 100 V, 25 °C | 43 μA (typ), 350 μA (max) - low leakage preserves battery standby life in reverse polarity protection |
Pinout & Package
Package: D2PAK (TO-263AB), surface-mount, single-diode configuration with isolated anode and cathode terminals plus two NC (no-connect) pins. Exposed metal tab is cathode (K) and serves as thermal path to heatsink.

|---|---|---|
| Pin 1 (NC) | No connection | Internal die isolation; not bonded; must remain unconnected on PCB |
| Pin 2 (A) | Anode | Input side of rectification path; connects to source or switch node in buck/flyback |
| Pin 3 (K) | Cathode | Output side and thermal pad; electrically and thermally tied to heatsink plane |

Applications
| High-Frequency DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Used in secondary-side synchronous rectification of 300 kHz–1 MHz isolated DC/DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Freewheeling Schottky rectifier replacing MOSFET+driver in low-side position to reduce gate drive complexity. Use Value: 0.76 V VF at 30 A cuts conduction loss by >40 % versus 1.2 V Si diode, improving full-load efficiency by 1.2–1.8 %. | Use Scenario: Placed in series with vehicle battery feed to prevent damage during accidental reverse connection. IC Role / Device Role / Timing Role: Unidirectional blocking element with low forward drop to minimize voltage loss in normal operation. Use Value: 0.44 V VF at 5 A and 125 °C ensures <220 mW dissipation at 5 A - avoids thermal shutdown in hot under-hood conditions. |
| OR-ing Diode in Redundant Power Supplies | Freewheeling Diode in Switching Regulators |
Use Scenario: Parallel-connected in N+1 redundant 12 V/48 V systems to isolate failed supplies while maintaining load continuity. IC Role / Device Role / Timing Role: High-current, low-VF diode enabling automatic current steering without control circuitry. Use Value: 250 A IFSM rating handles inrush surges during hot-swap events; 2.0 °C/W RθJC prevents thermal runaway during sustained 30 A sharing. | Use Scenario: Positioned across inductive loads (e.g., solenoids, motor windings) in industrial PLC output stages. IC Role / Device Role / Timing Role: Fast-recovery freewheeling path that clamps inductive kickback and sustains current during switch-off. Use Value: 10,000 V/μs dV/dt rating suppresses oscillation during rapid voltage reversal; 150 °C TJ max allows operation near heat-generating logic ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG-TR | Same 100 V VRRM, 30 A IF(AV), but VF = 0.82 V @ 30 A; RθJC = 2.5 °C/W; TO-247AC package | Higher thermal resistance and through-hole mounting require larger board area and heatsink interface redesign | Choose when legacy TO-247 footprint is fixed and 0.06 V higher VF is acceptable |
| ON Semi SB3100-E3/45 | Lower 10 A IF(AV), 100 V VRRM, VF = 0.82 V @ 10 A; D2PAK package; no MSL Level 1 or JESD 201 certification | Not suitable for 30 A continuous designs; lacks automotive-grade whisker and moisture resistance | Consider only for cost-sensitive, low-current (<12 A), non-automotive applications where qualification is not required |
Compared with STPS30H100CG-TR and SB3100-E3/45, the VB30100SG-M3/4W delivers superior thermal performance (2.0 vs. 2.5 °C/W), lower conduction loss (0.76 vs. ≥0.82 V), and full automotive-grade process qualifications - making it optimal for space-constrained, high-reliability 30 A power paths.

FAQ
What is the maximum junction temperature rating for VB30100SG-M3/4W?
The VB30100SG-M3/4W has a maximum junction temperature (TJ max.) of +150 °C, verified per datasheet revision 20-Jun-2018. This rating allows sustained operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. Derating curves in Figure 1 confirm 30 A IF(AV) is maintainable up to 100 °C case temperature when mounted to an adequate heatsink. The VB30100SG-M3/4W must be thermally managed to ensure TJ does not exceed this limit during peak load conditions.
Does VB30100SG-M3/4W support lead-free reflow soldering?
Yes, VB30100SG-M3/4W is qualified to MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 245 °C, making it compatible with standard lead-free soldering processes. The M3 suffix confirms halogen-free, RoHS-compliant construction and JESD 201 Class 1A whisker resistance. No pre-baking is required prior to reflow, simplifying manufacturing flow. The VB30100SG-M3/4W datasheet explicitly states compliance with these industry standards.
What is the forward voltage of VB30100SG-M3/4W at 10 A and 125 °C?
The VB30100SG-M3/4W exhibits a typical forward voltage of 0.55 V at 10 A and 125 °C, with a maximum of 0.65 V under those conditions. This low, temperature-stable VF is enabled by its trench MOS Schottky architecture and is critical for maintaining efficiency in high-temperature applications like under-hood automotive modules. The VB30100SG-M3/4W datasheet Table "ELECTRICAL CHARACTERISTICS" lists this value directly under test condition TA = 125 °C.
How many pins does VB30100SG-M3/4W have, and what are their functions?
The VB30100SG-M3/4W has four physical pins in its D2PAK (TO-263AB) package: Pin 1 and Pin 4 are NC (no-connect), Pin 2 is the anode (A), and Pin 3 is the cathode (K) - which also forms the exposed thermal pad. The NC pins are internally unconnected and must remain unattached on the PCB. The VB30100SG-M3/4W pinout is confirmed in the mechanical drawing and schematic symbol on page 1 of the official Vishay datasheet (Doc. #87986).
Is VB30100SG-M3/4W suitable for reverse battery protection in 24 V automotive systems?
Yes, VB30100SG-M3/4W is well-suited for reverse battery protection in 24 V automotive systems due to its 100 V VRRM rating (providing 4× margin over nominal 24 V), low 0.44 V VF at 5 A and 125 °C, and automotive-qualified M3 suffix (JESD 201 Class 1A, MSL Level 1). Its 150 °C TJ max and 2.0 °C/W RθJC allow reliable operation even in hot under-hood locations. The VB30100SG-M3/4W is explicitly cited in Vishay's typical applications for reverse battery protection.
