Product details
Overview
VF20150S-M3/4W from Vishay General Semiconductor is a high-voltage trench MOS barrier Schottky rectifier in ITO-220AB package, rated for 150 V reverse voltage, 20 A average forward current, and 0.75 V forward voltage at 20 A. It delivers ultra-low VF of 0.55 V at 5 A and 125 °C, enabling high-efficiency operation in DC/DC converters and reverse battery protection circuits.
For engineers reviewing the VF20150S-M3/4W datasheet, VF20150S-M3/4W pinout, VF20150S-M3/4W application, or VF20150S-M3/4W equivalent, key selection considerations include its 160 A surge rating, 4.0 °C/W junction-to-case thermal resistance, 10,000 V/μs dV/dt capability, and halogen-free RoHS-compliant M3 termination.
Technical Context
This device uses trench MOS Schottky technology to achieve lower forward voltage and reduced switching losses compared to planar Schottky or fast recovery diodes. Its 150 V VRRM rating and 150 °C maximum junction temperature support operation in demanding industrial and automotive power systems.
The ITO-220AB package provides direct heatsink mounting with 1500 V isolation voltage and 10 in-lbs max torque. The single-diode configuration features anode-cathode-anode pinout (pins 1–3), enabling standard freewheeling and OR-ing topologies without external paralleling.
Key Specifications

| VRRM | 150 V - supports input rails up to 150 V DC without breakdown |
| IF(AV) | 20 A - continuous conduction capability with appropriate heatsinking |
| IFSM | 160 A - withstands short-duration inrush or fault currents |
| VF @ 20 A, 25 °C | 0.75 V - low conduction loss reduces heat generation in high-current paths |
| RθJC | 4.0 °C/W - enables efficient thermal transfer to heatsink for sustained 20 A operation |
| dV/dt | 10,000 V/μs - resists false turn-on in high-speed switching environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VF20150S-M3 | Same die and electrical specs; differs only in packaging - supplied in tape-and-reel (4W = tube) vs. bulk (M3 = standard reel) | No functional difference; tube format preferred for low-volume prototyping and manual assembly | Select VF20150S-M3/4W when tube delivery and 50-unit lot sizing align with production workflow |
| STPS20H150CG | 150 V, 20 A, but VF = 0.85 V @ 20 A; TO-220AC package with non-isolated tab; RθJC = 3.0 °C/W | Lacks 1500 V isolation - requires insulating pad for heatsink mounting; higher VF increases conduction loss | Choose STPS20H150CG only if isolation is unnecessary and lower thermal resistance outweighs VF penalty |
Compared with VF20150S-M3/4W, VF20150S-M3 offers identical performance in reel format for automated placement, while STPS20H150CG trades isolation and lower VF for marginally better thermal resistance but requires additional insulation and dissipates ~2 W more at full load.

FAQ
What is the maximum junction temperature rating for VF20150S-M3/4W?
The VF20150S-M3/4W has a maximum junction temperature (TJ max.) of +150 °C, verified per datasheet revision 08-Mar-18. This rating allows reliable operation in enclosed industrial enclosures or under-hood automotive environments when mounted on a heatsink with adequate thermal design. Derating curves in Figure 1 confirm 20 A IF(AV) is maintained up to 100 °C case temperature.
Does VF20150S-M3/4W have isolated mounting capability?
Yes, VF20150S-M3/4W uses the ITO-220AB package with 1500 V AC isolation (1 minute) between the thermal tab and pin 2 (cathode). This permits direct mounting to a grounded heatsink without insulating hardware, reducing thermal resistance and simplifying mechanical integration in high-density power designs.
What is the forward voltage of VF20150S-M3/4W at 5 A and 125 °C?
The VF20150S-M3/4W exhibits a typical forward voltage of 0.55 V at IF = 5 A and TA = 125 °C, as specified in the Electrical Characteristics table on page 2 of document 89268. This ultra-low VF value is enabled by trench MOS Schottky technology and contributes directly to improved efficiency in high-temperature operating conditions.
Is VF20150S-M3/4W RoHS-compliant and halogen-free?
Yes, VF20150S-M3/4W carries the M3 suffix, indicating it is halogen-free, RoHS-compliant, and commercial-grade per Vishay's material categorization standard (document 99912). Its matte tin-plated leads meet J-STD-002 solderability requirements and JESD 201 Class 1A whisker testing for long-term reliability.
What is the peak surge current rating for VF20150S-M3/4W?
The VF20150S-M3/4W is rated for a non-repetitive peak forward surge current (IFSM) of 160 A at 8.3 ms single half-sine wave, per Maximum Ratings table on page 1 of document 89268. This rating ensures robustness against inrush currents during power-up or transient overloads in DC/DC and battery-protection applications.
