Product details
Overview
V2PM12LHM3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier configured as a single diode, rated for 120 V repetitive peak reverse voltage (VRRM), 2.0 A average forward current (IF(AV)), and 0.60 V forward voltage at 2.0 A. It operates up to 175 °C junction temperature and is AEC-Q101 qualified for automotive polarity protection and DC/DC converter applications.
For engineers reviewing the V2PM12LHM3/H datasheet, V2PM12LHM3/H pinout, V2PM12LHM3/H application, or V2PM12LHM3/H equivalent, key selection criteria include its low VF (0.60 V @ 2 A), 50 A surge rating (IFSM), SMP (DO-220AA) package thermal resistance (RθJA = 125 °C/W), and AEC-Q101 qualification status - all critical for high-efficiency, space-constrained automotive power designs.
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and higher efficiency than planar Schottky or standard PN diodes. Its 120 V VRRM and 175 °C maximum junction temperature support operation in 48 V automotive systems and industrial DC/DC stages where thermal margin and reverse blocking are essential.
The device features a color-banded cathode, matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 (peak reflow 260 °C). The SMP (DO-220AA) package delivers low profile and high power density, with RθJM = 15 °C/W when mounted on recommended copper pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - blocks up to 120 V reverse voltage without breakdown in freewheeling or polarity protection circuits |
| IF(AV) | 2.0 A - continuous DC forward current capability at 10 mm × 10 mm copper pad, defining usable steady-state power handling |
| VF @ 2.0 A | 0.60 V - reduces conduction loss to ~1.2 W per device, improving system efficiency in high-frequency converters |
| IFSM | 50 A - withstands short-duration inrush or fault currents (10 ms half-sine), supporting robust overcurrent resilience |
| TJ max. | 175 °C - enables operation in under-hood automotive environments and thermally demanding industrial enclosures |
| CJ | 180 pF @ 4.0 V - limits switching-related capacitive losses and EMI generation in >100 kHz DC/DC topologies |
| RθJA | 125 °C/W - defines thermal derating slope when mounted on standard PCB; requires thermal pad design for full IF(AV) utilization |
Pinout & Package
Package: SMP (DO-220AA) - low-profile, surface-mount plastic package with molded UL 94 V-0 compound, cathode identified by color band. Dimensions: 4.00 mm × 2.60 mm × 1.35 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to input/source side in forward-biased configuration; must be routed with low-inductance trace for high-frequency switching |
| Cathode | Current exit terminal | Marked with color band; ties to output/load or ground return path; serves as thermal mounting interface on PCB copper pad |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Enables 0.60 V VF at 2 A - 15–25 % lower than comparable planar Schottky diodes, directly reducing conduction loss |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for under-hood ECUs and ADAS power rails |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without preconditioning - eliminates moisture sensitivity handling overhead in SMT lines |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates (IEC 61249-2-21) without compromising thermal or electrical performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V2PM12L-M3/H | Commercial-grade version; same electrical specs but not AEC-Q101 qualified; no HM3 suffix | Suitable for industrial or consumer DC/DC where automotive qualification is unnecessary | Select when cost sensitivity outweighs automotive reliability requirements and ambient temperature stays ≤ 150 °C |
| SS212H | 2 A / 120 V Schottky in SMA package; VF = 0.85 V @ 2 A; RθJA = 160 °C/W; no AEC-Q101 | Larger footprint, higher thermal resistance, and higher conduction loss limit use in compact or high-temp environments | Consider only if SMP package compatibility is not required and board space permits larger outline |
Compared with V2PM12LHM3/H, V2PM12L-M3/H offers identical performance without automotive qualification, while SS212H trades higher VF and thermal resistance for broader distributor availability - making V2PM12LHM3/H optimal for space-constrained, thermally aggressive AEC-Q101–mandated designs.

FAQ
What is the maximum junction temperature rating for V2PM12LHM3/H?
The V2PM12LHM3/H has a maximum junction temperature (TJ) of +175 °C, verified per the Vishay datasheet revision 08-Mar-2022. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in Figure 1 confirm usable current down to 125 °C mount temperature. Thermal design must respect RθJA = 125 °C/W and RθJM = 15 °C/W to avoid exceeding this limit in the V2PM12LHM3/H.
Is V2PM12LHM3/H pin-compatible with V2PM12L-M3/H?
Yes - V2PM12LHM3/H and V2PM12L-M3/H share identical SMP (DO-220AA) package dimensions, anode/cathode terminal layout, and solder pad footprint. The only difference is qualification: V2PM12LHM3/H carries AEC-Q101 certification (denoted by HM3 suffix), while V2PM12L-M3/H is commercial-grade. No PCB changes are required when upgrading from V2PM12L-M3/H to V2PM12LHM3/H in automotive designs.
What does the "HM3" suffix indicate in V2PM12LHM3/H?
The "HM3" suffix in V2PM12LHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay documentation, HM3 identifies the automotive-grade variant - distinct from the commercial "M3" suffix - and confirms compliance with JESD 201 class 2 whisker testing and MSL Level 1 reflow capability. This suffix is integral to the V2PM12LHM3/H ordering code and reflects its intended use in automotive applications.
Does V2PM12LHM3/H meet JEDEC moisture sensitivity requirements?
Yes - V2PM12LHM3/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means the V2PM12LHM3/H can be placed directly into lead-free reflow ovens without baking or dry-pack handling, simplifying manufacturing flow. The qualification is confirmed in the "Mechanical Data" section of the Vishay datasheet (Document Number: 87466), and applies specifically to the HM3-suffixed V2PM12LHM3/H.
What is the typical forward voltage of V2PM12LHM3/H at 125 °C junction temperature?
At 125 °C junction temperature and 2.0 A forward current, the V2PM12LHM3/H exhibits a typical forward voltage (VF) of 0.60 V, with a maximum of 0.68 V per the Electrical Characteristics table. This low, stable VF across temperature is enabled by trench MOS Schottky architecture and makes the V2PM12LHM3/H especially effective in thermally demanding applications like automotive DC/DC converters where conduction loss must remain predictable at elevated temperatures.
