Product details
Overview
V12P22-M3/H from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 200 V reverse voltage, 12 A average forward current, and 0.68 V forward voltage at 12 A and 125 °C - optimized for low-loss DC/DC converters and freewheeling in automotive and industrial power supplies.
For engineers reviewing the V12P22-M3/H datasheet, V12P22-M3/H pinout, V12P22-M3/H application, or V12P22-M3/H equivalent, key selection criteria include its ultra-low VF (0.60 V at 6 A, 125 °C), AEC-Q101-qualified variant availability, MSL Level 1 solderability, and junction-to-mount thermal resistance of 4 °C/W on aluminum PCBs.
Technical Context
This single-diode TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and higher efficiency than planar Schottky or standard PN diodes. Its 200 A surge rating (IFSM) and 175 °C max junction temperature support robust operation in high-reliability switching power stages.
The SMPC (TO-277A) package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, with M3 suffix indicating halogen-free, RoHS-compliant commercial grade construction and JESD 201 Class 2 whisker resistance.
Key Specifications

| VRRM | 200 V - supports input rails up to 170 VDC with 15 % margin in offline or 48 V bus systems |
| IF(AV) | 12 A - continuous conduction capability at TA = 25 °C on 30 mm × 30 mm Al PCB |
| VF @ 12 A, 125 °C | 0.68 V - enables <0.82 W conduction loss per device in high-temp environments |
| IFSM | 200 A - withstands short-duration inrush and fault currents without bond-wire failure |
| RθJM | 4 °C/W - enables effective heat transfer to metal-core PCBs, critical for compact power modules |
| TJ max | 175 °C - allows operation in under-hood automotive or sealed industrial enclosures |
| CJ @ 4 V | 720 pF - limits capacitive turn-on loss and EMI in >100 kHz switching topologies |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with dual anode pads and common cathode tab. Height: 1.1 mm typical; meets UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pad) | Forward current entry point | Electrically tied to Anode 2; parallel internal connection doubles current-carrying cross-section |
| Anode 2 (Pad) | Forward current entry point | Shares same potential as Anode 1; improves thermal spreading and reduces pad resistance |
| Cathode (Tab) | Current return path / thermal interface | Exposed metal tab serves as primary heat sink contact; must be soldered to large copper area or aluminum baseplate |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V12P22HM3_A/H | AEC-Q101 qualified; identical electrical specs and SMPC package; "HM3" denotes automotive grade | Required for automotive ECUs, ADAS power modules, and under-hood applications requiring qualification evidence | Select when automotive qualification documentation and traceability are mandatory |
| SS1220H | 12 A, 200 V Schottky; TO-277 package (not TO-277A); VF = 0.72 V @ 12 A, 25 °C; RθJA = 85 °C/W | Suitable for cost-sensitive industrial designs where 50 mV VF penalty and 5 °C/W higher RθJA are acceptable | Choose for non-automotive, non-thermal-critical applications with legacy TO-277 footprint compatibility |
Compared with V12P22HM3_A/H, the V12P22-M3/H offers identical performance but lacks AEC-Q101 certification; versus SS1220H, it delivers lower VF, better thermal resistance, and tighter process control - making it preferable for thermally constrained or high-efficiency designs.

FAQ
What is the maximum junction temperature rating for the V12P22-M3/H?
The V12P22-M3/H has a maximum junction temperature (TJ max) of +175 °C, enabling reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. This rating is validated per JEDEC test conditions and supported by its RθJM of 4 °C/W on aluminum PCBs. The V12P22-M3/H maintains stable VF and leakage performance up to this limit, with IR remaining ≤3 mA at VR = 200 V and TJ = 125 °C.
Is the V12P22-M3/H pin-compatible with the AEC-Q101-qualified V12P22HM3_A/H?
Yes, the V12P22-M3/H and V12P22HM3_A/H share identical SMPC (TO-277A) mechanical dimensions, terminal layout, and pinout - both feature dual anode pads and a common cathode tab. They are mechanically interchangeable on the same PCB footprint. However, the V12P22-M3/H is commercial-grade only, while V12P22HM3_A/H carries full AEC-Q101 qualification documentation and traceability required for automotive use. The V12P22-M3/H remains functionally identical in all electrical and thermal specifications.
What does the "M3" suffix mean in V12P22-M3/H?
The "M3" suffix in V12P22-M3/H indicates halogen-free, RoHS-compliant construction meeting IEC 61249-2-21 and EU Directive 2011/65/EU, with matte tin-plated leads qualified per J-STD-002 and JESD 22-B102. It also signifies compliance with JESD 201 Class 2 whisker resistance. The "/H" denotes 7-inch tape-and-reel packaging with 1500 units per reel. The V12P22-M3/H is not AEC-Q101 qualified - that requires the "HM3" prefix, as in V12P22HM3_A/H.
How does the V12P22-M3/H perform at elevated temperature compared to standard Schottky diodes?
The V12P22-M3/H delivers 0.60 V VF at 6 A and 125 °C - significantly lower than typical planar Schottky diodes (≥0.75 V under same conditions). This is achieved via trench MOS barrier technology, which suppresses reverse leakage while maintaining low forward drop. At 175 °C, IR remains ≤12 mA at VR = 200 V, ensuring stable blocking behavior. The V12P22-M3/H thus sustains higher efficiency and lower thermal runaway risk in thermally demanding applications where standard Schottky devices degrade rapidly.
Can the V12P22-M3/H be used in synchronous rectification topologies?
No - the V12P22-M3/H is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET-based controller. It functions as a unidirectional, self-commutating diode and cannot be actively gated. However, it is widely deployed as the secondary-side rectifier in non-synchronous flyback, forward, and LLC converters where its low VF and fast recovery (<50 ns) reduce losses relative to PN diodes. For true synchronous rectification, discrete MOSFETs or dedicated SR controllers (e.g., Vishay SiHP series + IC drivers) are required - the V12P22-M3/H serves as the benchmark passive alternative.
