Product details
Overview
V12PM6HM3/H from Vishay General Semiconductor is a high-current-density Trench MOS Barrier Schottky (TMBS®) rectifier in SMPC (TO-277A) package, rated for 12 A average forward current, 60 V reverse voltage, and 0.52 V forward voltage at 12 A and 125 °C - optimized for low-loss DC/DC converters and automotive polarity protection.
For engineers reviewing the V12PM6HM3/H datasheet, V12PM6HM3/H pinout, V12PM6HM3/H application, or V12PM6HM3/H equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low VF (0.39 V @ 6 A, 125 °C), 175 °C max junction temperature, and thermal resistance of 4 °C/W junction-to-mount on aluminum PCB.
Technical Context
This device uses trench MOS Schottky technology to achieve lower forward voltage and higher current density than planar Schottky diodes. Its single-anode dual-cathode configuration (Anode 1, Anode 2, Cathode K) enables parallel anode routing for reduced conduction loss in high-current paths.
The SMPC (TO-277A) package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, MSL Level 1 rating, and 260 °C peak reflow tolerance. Thermal performance is specified with RθJM = 4 °C/W when mounted on a 30 mm × 30 mm aluminum PCB.
Key Specifications

| VRRM | 60 V - supports 48 V nominal bus systems with 25 % safety margin against transients |
| IF(AV) | 12.0 A - continuous DC output capability in compact surface-mount footprint |
| VF @ 12 A, 125 °C | 0.52 V - enables <1.2 W conduction loss per device in high-temp operation |
| IFSM | 200 A - withstands short-duration inrush and fault currents in DC/DC startup |
| TJ max | 175 °C - allows operation in under-hood automotive environments without derating |
| CJ | 2050 pF @ 4 V, 1 MHz - limits high-frequency switching noise in >100 kHz converters |
| RθJM | 4 °C/W - enables efficient heat transfer to metal-core PCBs for thermal management |
Pinout & Package
Package: SMPC (TO-277A), ultra-low-profile surface-mount case with 1.1 mm typical height, UL 94 V-0 molding compound, halogen-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V12PM6-M3/H | Commercial-grade version; identical electrical specs but not AEC-Q101 qualified | Suitable for industrial or consumer DC/DC where automotive qualification is unnecessary | Select when cost sensitivity outweighs automotive compliance requirements |
| SS12P6LHM3/H | Same 12 A / 60 V rating, but uses planar Schottky architecture; VF = 0.58 V @ 12 A, 25 °C (higher loss) | Limited to lower ambient temperature environments due to 150 °C TJ max | Choose only if TMBS® availability is constrained and thermal margin permits higher VF |
Compared with V12PM6HM3/H, the V12PM6-M3/H offers identical performance at lower cost but lacks automotive qualification, while SS12P6LHM3/H trades higher forward voltage and lower temperature rating for broader legacy supply chain availability.

FAQ
What is the maximum junction temperature rating for V12PM6HM3/H?
The V12PM6HM3/H has a maximum junction temperature (TJ) of +175 °C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings without forced cooling. The V12PM6HM3/H maintains stable forward voltage and leakage characteristics up to this limit, supporting robust thermal design margins.
Is V12PM6HM3/H pin-compatible with V12PM6-M3/H?
Yes, V12PM6HM3/H and V12PM6-M3/H share identical SMPC (TO-277A) packaging, pinout (Anode 1, Anode 2, Cathode K), and mechanical dimensions. The only difference is qualification status: V12PM6HM3/H is AEC-Q101 qualified, while V12PM6-M3/H is commercial grade. No PCB layout change is required when substituting between them.
What does the "HM3" suffix indicate in V12PM6HM3/H?
The "HM3" suffix in V12PM6HM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" specifies the 7-inch tape-and-reel packaging format (1500 units per reel), and "M3" confirms compliance with JESD201 Class 2 whisker resistance and JEDEC TO-277A mechanical standards. This suffix distinguishes it from commercial variants like V12PM6-M3/H.
How does the dual-anode configuration of V12PM6HM3/H improve thermal performance?
The dual-anode structure (Anode 1 and Anode 2) in V12PM6HM3/H allows current to split across two parallel internal paths, reducing current density per metallization segment and lowering localized heating. Combined with the low RθJM of 4 °C/W, this design improves thermal coupling to the PCB mount pad - critical for sustaining 12 A continuous current in compact layouts without thermal derating.
Can V12PM6HM3/H be used in synchronous rectification circuits?
No, V12PM6HM3/H is a passive Schottky rectifier and cannot replace a MOSFET-based synchronous rectifier controller. It functions as a unidirectional freewheeling or polarity protection device. For synchronous rectification, a gate-driven N-channel MOSFET with appropriate timing control is required. The V12PM6HM3/H may serve as a fallback diode in synchronous designs during startup or fault conditions.
