Product details
Overview
V3N22-M3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 200 V repetitive peak reverse voltage and 3 A average forward current at infinite heatsink, with low 0.61 V forward voltage at 1.5 A and 125 °C junction temperature-used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V3N22-M3/H datasheet, V3N22-M3/H pinout, V3N22-M3/H application, or V3N22-M3/H equivalent, key selection criteria include its AEC-Q101-qualified variant availability, side-wettable flanks for AOI compatibility, 175 °C max junction temperature, and thermal resistance of 135 °C/W (junction-to-ambient on FR4).
Technical Context
The V3N22-M3/H employs trench MOS Schottky technology to achieve low forward voltage drop and high switching efficiency at high frequencies. Its single-diode configuration supports unidirectional conduction with cathode marked by color band, and it operates across -40 °C to +175 °C junction temperature range.
Designed for low-voltage, high-frequency power conversion, the device delivers 0.76 V typical forward voltage at 1.5 A and 25 °C, with reverse leakage under 0.05 mA at 200 V and 25 °C. Thermal performance is characterized by RθJM = 5 °C/W and RθJA = 135 °C/W per JEDEC 51-2A on standard FR4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V reverse voltage without breakdown in repetitive operation |
| IF(AV) | 3 A - maximum average forward current with infinite heatsink cooling |
| VF @ 1.5 A, 125 °C | 0.61 V - enables low conduction loss in high-temperature DC/DC stages |
| IFSM | 60 A - withstands 8.3 ms surge currents common in motor drive freewheeling |
| TJ max. | +175 °C - supports operation in under-hood automotive and industrial environments |
| RθJA | 135 °C/W - defines thermal limit on standard 2 oz. FR4 PCB with defined footprint |
| CJ | 150 pF @ 4 V, 1 MHz - low capacitance minimizes switching losses in >100 kHz converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V3N22HM3/H | AEC-Q101 qualified; identical electrical specs and DFN3820A package | Required for automotive production; same thermal and electrical behavior | Select when automotive qualification and traceable lot documentation are mandatory |
| SS220H | DO-220AA (SMP) package; 200 V, 2 A IF(AV); VF = 0.82 V @ 1.5 A, 25 °C | Higher VF and lower current rating; through-hole or larger SMT footprint | Choose only if DFN3820A footprint is unavailable and 2 A rating suffices |
Compared with V3N22-M3/H, V3N22HM3/H adds automotive qualification without altering performance, while SS220H trades lower cost and legacy package compatibility for reduced current capability and higher conduction loss-making V3N22-M3/H optimal for space-constrained, high-efficiency 3 A designs.

FAQ
What is the maximum junction temperature rating for V3N22-M3/H?
The V3N22-M3/H has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in high-ambient environments such as automotive under-hood modules or industrial power supplies. This rating is validated per JEDEC test conditions and must be maintained using appropriate PCB copper area and thermal design per the datasheet's derating curves.
Does V3N22-M3/H have AEC-Q101 qualification?
No, V3N22-M3/H is the commercial-grade version. The AEC-Q101-qualified variant is V3N22HM3/H, which shares identical electrical and thermal specifications but includes automotive-specific stress testing and traceability. For automotive production, V3N22HM3/H-not V3N22-M3/H-is required.
What does the "M3" suffix mean in V3N22-M3/H?
The "M3" suffix in V3N22-M3/H indicates halogen-free, RoHS-compliant construction with matte tin-plated terminals meeting JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards. It also denotes commercial-grade qualification, distinguishing it from the "HM3" automotive variant.
Can V3N22-M3/H replace a DO-220AA (SMP) package diode?
Yes-V3N22-M3/H is mechanically compatible with the SMP (DO-220AA) outline per Vishay documentation and uses the same DFN3820A case. However, PCB land pattern must be updated to match the side-wettable flank geometry and smaller footprint; direct drop-in replacement is not possible without layout revision.
What is the thermal resistance junction-to-ambient (RθJA) for V3N22-M3/H?
The V3N22-M3/H has a typical RθJA of 135 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended footprint per JEDEC 51-2A. This value assumes no additional heatsinking; actual thermal performance depends on board layout, copper area, and airflow.
