Product details
Overview
V12P22HM3/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 repetitive peak reverse voltage, 12 A average forward current, and 200 A non-repetitive surge current; it delivers ultra-low forward voltage of 0.68 V at 12 A and 125 °C, enabling high-efficiency DC/DC conversion in space-constrained power supplies.
For engineers reviewing the V12P22HM3/H datasheet, V12P22HM3/H pinout, V12P22HM3/H application, or V12P22HM3/H equivalent, key selection criteria include its AEC-Q101 qualification status, 175 °C maximum junction temperature, 80 °C/W junction-to-ambient thermal resistance, low-profile 1.1 mm height, and suitability for automotive-grade freewheeling and polarity protection circuits.
Technical Context
This device employs trench MOS Schottky technology to achieve lower forward voltage and higher current density than planar Schottky diodes. Its single-anode, dual-cathode configuration (K–1–2 pinout) supports high-current conduction with minimized thermal resistance via direct-mount aluminum PCB interface.
The V12P22HM3/H operates across –40 °C to +175 °C junction temperature range and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow peak. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive applications - confirmed by the "HM3" suffix and documented revision history.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V reverse voltage without breakdown; suitable for 48 V and 60 V bus systems with margin. |
| IF(AV) | 12 A - continuous DC forward current rating at 125 °C on 30 mm × 30 mm Al PCB; defines steady-state power handling. |
| VF @ 12 A, 125 °C | 0.68 V - low conduction loss reduces heat generation and improves system efficiency in high-frequency converters. |
| IFSM | 200 A - withstands short-duration surges (8.3 ms half-sine), supporting robust input filtering and fault tolerance. |
| RθJA | 80 °C/W - thermal resistance from junction to ambient under defined pad layout; informs heatsinking requirements. |
| TJ(max) | 175 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| CJ | 720 pF @ 4.0 V, 1 MHz - low junction capacitance minimizes switching losses and EMI in high-frequency (>100 kHz) topologies. |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal, very low profile (1.1 mm typical height), matte tin-plated leads, UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K (Cathode) | Common cathode terminal | Connected to output rail or ground return path; large copper area required for thermal dissipation. |
| 1 (Anode) | Anode 1 | Primary anode connection for main current path; electrically identical to Pin 2 in parallel configuration. |
| 2 (Anode) | Anode 2 | Secondary anode terminal - internally paralleled with Pin 1 to share current and reduce effective series resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Enables 0.68 V VF at 12 A/125 °C - 15–20 % lower than comparable planar Schottky diodes, reducing conduction loss. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS power stages; requires HM3 suffix. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard SMT reflow without baking - simplifies manufacturing logistics. |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates without compromising thermal or electrical performance. |
| Low-profile 1.1 mm height | Enables use in ultra-thin power modules and stacked PCB assemblies where Z-axis clearance is constrained. |
Applications
| Automotive DC/DC Converters | Industrial Freewheeling Diodes |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V12P22-M3/H | Commercial grade; no AEC-Q101 qualification; same electrical specs and package. | Not approved for automotive use; suitable for industrial/commercial power supplies only. | Select when AEC-Q101 is not required and cost optimization is prioritized. |
| SS12P20HM3/H | 200 V VRRM, 12 A IF(AV), but uses planar Schottky; VF = 0.75 V @ 12 A/125 °C (higher loss). | Limited to non-automotive applications due to lack of AEC-Q101; lower current density. | Choose only if TMBS® process availability is constrained; expect ~0.8 W higher conduction loss at full load. |
Compared with V12P22-M3/H and SS12P20HM3/H, the V12P22HM3/H uniquely combines AEC-Q101 qualification, trench-based low VF, and TO-277A thermal performance - making it the only option qualified for under-hood automotive rectification without derating.

FAQ
What is the maximum junction temperature rating for the V12P22HM3/H?
The V12P22HM3/H has a maximum junction temperature (TJ(max)) of +175 °C, verified per datasheet revision 20-Apr-2023. This rating allows reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Thermal design must ensure that actual junction temperature stays below this limit under worst-case load and ambient conditions - the V12P22HM3/H achieves this with RθJM = 4 °C/W when mounted on aluminum PCB.
Is the V12P22HM3/H pin-compatible with the V12P22-M3/H?
Yes, the V12P22HM3/H and V12P22-M3/H share identical SMPC (TO-277A) package dimensions, pinout (K–1–2), and mechanical footprint. The only difference is qualification: V12P22HM3/H is AEC-Q101 qualified, while V12P22-M3/H is commercial grade. No PCB layout change is needed when upgrading from V12P22-M3/H to V12P22HM3/H in automotive designs.
What does the "HM3" suffix indicate in V12P22HM3/H?
The "HM3" suffix in V12P22HM3/H denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification for automotive applications. It distinguishes the part from commercial-grade variants like V12P22-M3/H and confirms compliance with stress testing including temperature cycling, humidity bias, and high-temperature operating life - all documented in Vishay's qualification report for this base P/N.
What is the typical forward voltage of the V12P22HM3/H at 6 A and 25 °C?
The typical forward voltage (VF) of the V12P22HM3/H is 0.75 V at 6 A and 25 °C, as specified in the Electrical Characteristics table of datasheet 87019. This value reflects the low-loss advantage of trench MOS Schottky architecture and is measured under pulsed conditions (300 μs, 1 % duty cycle) to avoid self-heating effects.
Does the V12P22HM3/H meet JEDEC moisture sensitivity level requirements?
Yes, the V12P22HM3/H meets J-STD-020 Moisture Sensitivity Level (MSL) 1, with a maximum peak reflow temperature of 260 °C for lead-free soldering. This allows indefinite floor life and eliminates the need for pre-baking before SMT assembly - a key advantage for high-volume automotive and industrial manufacturing lines.
