Product details
Overview
VI30100SG-E3/4W from Vishay General Semiconductor is a high-voltage trench MOS barrier Schottky rectifier in TO-262AA package, rated for 100 V repetitive reverse voltage and 30 A average forward current, with ultra-low 0.76 V forward voltage at 30 A and 250 A surge capability - used as freewheeling or OR-ing diode in DC/DC converters and reverse battery protection circuits.
For engineers reviewing the VI30100SG-E3/4W datasheet, VI30100SG-E3/4W pinout, VI30100SG-E3/4W application, or VI30100SG-E3/4W equivalent, key selection criteria include thermal resistance (2.0 °C/W junction-to-case), low VF at high temperature, MSL level 1 compliance, and TO-262AA mounting compatibility with heatsink isolation requirements.
Technical Context
This device employs trench MOS Schottky technology to achieve lower forward voltage and higher efficiency than planar Schottky or fast recovery diodes. Its single-diode configuration supports unidirectional conduction with cathode-anode polarity marked on case.
Thermal performance is optimized via low RθJC of 2.0 °C/W and maximum junction temperature of 150 °C, enabling operation in compact power supplies without forced air cooling. The TO-262AA package provides mechanical robustness and thermal path to heatsink while maintaining electrical isolation up to 1500 VAC (ITO-220AB only; not applicable to VI30100SG-E3/4W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V reverse voltage in switching applications without breakdown. |
| IF(AV) | 30 A - delivers continuous forward current up to 30 A at 25 °C case temperature. |
| VF @ 30 A | 0.76 V - reduces conduction loss to <23 W at full load, improving system efficiency. |
| IFSM | 250 A - withstands short-duration surge currents typical during power-up or fault conditions. |
| RθJC | 2.0 °C/W - enables effective heat transfer from junction to heatsink in TO-262AA mounting. |
| TJ max. | 150 °C - supports reliable operation in high-ambient industrial and automotive under-hood environments. |
| EAS | 230 mJ - absorbs non-repetitive avalanche energy during inductive switching transients. |
Pinout & Package
VI30100SG-E3/4W uses the TO-262AA package - a straight-lead variant of TO-220 with isolated tab, optimized for automated insertion and improved thermal dissipation. Mounting torque must not exceed 10 in-lbs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (A) | Input terminal for forward current flow; connects to source side in freewheeling or OR-ing topology. |
| Pin 2 | Cathode (K) | Output terminal; carries forward current to load or return path; electrically connected to metal tab. |
| Pin 3 | No Connect (NC) | Internally unconnected lead; must remain floating - no circuit function or thermal benefit. |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky architecture | Enables 0.76 V VF at 30 A - 15–20 % lower than comparable planar Schottky diodes, reducing conduction loss. |
| Low thermal resistance (RθJC = 2.0 °C/W) | Permits 30 A continuous operation with ≤60 °C temperature rise above heatsink, simplifying thermal design. |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test and JEDEC J-STD-002 solderability standards for long-term reliability. |
| 150 °C maximum junction temperature | Supports operation in sealed enclosures or high-ambient environments without derating below 30 A until TC > 95 °C. |
| 250 A IFSM rating | Handles peak inrush or fault currents in 48 V telecom and industrial DC bus systems without failure. |
Applications
| High-Frequency DC/DC Converters | Reverse Battery Protection |
|---|---|
|
Use Scenario: Used in synchronous buck converter output stage as low-loss freewheeling diode alongside high-side MOSFET. IC Role / Device Role / Timing Role: Unidirectional power path control during low-side conduction phase; replaces body diode to minimize VF-related loss. Use Value: 0.76 V VF at 30 A cuts conduction loss by ~35 % vs. standard FRD, increasing efficiency from 92 % to 94.5 % at 12 V/30 A output. |
Use Scenario: Placed in series with battery input to prevent damage from reverse polarity connection in automotive infotainment modules. IC Role / Device Role / Timing Role: Forward-conducting blocking element that conducts only when battery is correctly oriented; reverse-biased during misconnection. Use Value: 100 V VRRM and 250 A IFSM tolerate jump-start surges and clamp reverse faults without latch-up or thermal runaway. |
| OR-ing Diode in Redundant Power Supplies | Switching Power Supply Output Rectification |
|
Use Scenario: Parallel-connected in dual-input 12 V power supply to enable seamless switchover between primary and backup sources. IC Role / Device Role / Timing Role: Enables automatic current sourcing from higher-voltage rail while blocking reverse current from lower-voltage rail. Use Value: Ultra-low VF minimizes voltage drop across diode, preserving output regulation margin and reducing heat generation in confined spaces. |
Use Scenario: Secondary-side rectifier in 48 V input, 12 V/25 A telecom power supply operating at 200 kHz switching frequency. IC Role / Device Role / Timing Role: High-efficiency unidirectional current rectification with minimal reverse recovery charge (Qrr ≈ 0 nC). Use Value: Zero reverse recovery eliminates switching loss spikes and EMI associated with fast recovery diodes, easing EMI filter design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V30100SG-E3/4W (TO-220AB) | Same electrical specs but TO-220AB package; RθJC = 2.0 °C/W, no isolation, higher mounting torque tolerance (10 in-lbs). | Preferred where PCB through-hole mounting and direct heatsink contact are used; lacks NC pin. | Select when board layout accommodates TO-220AB footprint and thermal interface uses thermal compound + screw mount. |
| VB30100SG-E3/4W (TO-263AB) | Identical ratings; D2PAK package with exposed pad; RθJC = 2.0 °C/W; surface-mount compatible; no isolation rating. | Suitable for automated SMT assembly; requires thermal pad on PCB; no mechanical mounting hardware needed. | Choose for space-constrained designs requiring reflow assembly and reduced profile; verify PCB copper area meets thermal pad requirements. |
Compared with V30100SG-E3/4W and VB30100SG-E3/4W, VI30100SG-E3/4W offers TO-262AA's straight-lead insertion advantage and identical thermal/electrical performance - ideal for mixed-technology boards needing manual or wave-soldered high-current diodes with heatsink access.

FAQ
What is the maximum junction temperature rating for VI30100SG-E3/4W?
The VI30100SG-E3/4W has a maximum junction temperature (TJ) of +150 °C. This allows sustained operation in high-ambient environments such as enclosed power supplies or under-hood automotive applications. Derating begins above 95 °C case temperature, and the device maintains full 30 A IF(AV) rating up to that point per Fig. 1 in the datasheet.
Does VI30100SG-E3/4W have electrical isolation between terminals and heatsink?
No, VI30100SG-E3/4W in TO-262AA package does not provide electrical isolation between terminals and heatsink. Isolation (1500 VAC) is specified only for the ITO-220AB variant (VF30100SG-E3/4W). In VI30100SG-E3/4W, the metal tab is electrically connected to Pin 2 (cathode), requiring insulated mounting hardware if isolation is needed.
What is the forward voltage of VI30100SG-E3/4W at 10 A and 125 °C?
The VI30100SG-E3/4W exhibits a typical forward voltage of 0.55 V at 10 A and 125 °C, per the Electrical Characteristics table. This low temperature coefficient ensures stable conduction loss across operating range - critical for thermal stability in high-power density designs.
Is VI30100SG-E3/4W suitable for reverse battery protection in 24 V automotive systems?
Yes, VI30100SG-E3/4W is suitable for reverse battery protection in 24 V automotive systems. Its 100 V VRRM provides 4× safety margin against load dump transients (ISO 7637-2 Pulse 5a), and its 250 A IFSM rating handles jump-start surges. The 150 °C TJ max supports under-hood ambient temperatures.
What does the "4W" suffix mean in VI30100SG-E3/4W?
The "4W" in VI30100SG-E3/4W is Vishay's package code indicating tube packaging with 50 units per tube. It is not related to power rating. The "E3" suffix denotes RoHS-compliant matte tin plating and JESD 201 Class 1A whisker resistance - confirmed in the Ordering Information table and Mechanical Data section.
