Product details
Overview
V6N3103HM3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN33A package, rated for 100 V reverse voltage, 6 A average forward current, and 100 A surge current, with 0.45 V forward voltage at 3 A and 125 °C junction temperature-used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V6N3103HM3/I datasheet, V6N3103HM3/I pinout, V6N3103HM3/I application, or V6N3103HM3/I equivalent, key selection criteria include its AEC-Q101 qualification, low-profile side-wettable flanks for AOI compatibility, Gen3 TMBS low VF performance, and thermal resistance of 3.2 °C/W junction-to-mount.
Technical Context
This device implements a single-anode, four-terminal cathode configuration in a DFN33A package, enabling high-current conduction through parallel anode paths while maintaining low thermal resistance to the PCB mount plane. Its TMBS Gen3 architecture delivers reduced forward voltage versus conventional Schottky diodes without compromising reverse leakage at 125 °C.
The V6N3103HM3/I operates across -40 °C to +150 °C junction temperature range, supports MSL Level 1 reflow (260 °C peak), and meets JESD201 Class 2 whisker testing-making it suitable for automotive-grade power conversion where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V reverse voltage in freewheeling or polarity protection applications |
| IF(AV) | 6 A - continuous forward current rating with infinite heatsink; derates to 2.3 A in free-air FR4 mounting |
| IFSM | 100 A - withstands short-duration 8.3 ms surge events common in DC/DC converter startup or load dump |
| VF @ 3 A, 125 °C | 0.45 V - enables high-efficiency operation at elevated temperatures typical in automotive under-hood environments |
| RθJM | 3.2 °C/W - low junction-to-mount thermal resistance supports direct thermal coupling to copper pads on PCB |
| CJ | 730 pF @ 4 V, 1 MHz - low capacitance minimizes switching losses in high-frequency (>100 kHz) DC/DC topologies |
| TJ max. | +150 °C - extended junction temperature rating allows operation in thermally constrained automotive modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V6N3103-M3/I | Same electrical specs and DFN33A package, but commercial-grade (non-AEC-Q101 qualified) | Lacks automotive qualification; not approved for under-hood or safety-critical ECUs | Select when cost sensitivity outweighs automotive compliance requirements |
| SS310H | 3 A average current, TO-277 package, higher RθJA (≈160 °C/W), no side-wettable flanks | Lower current rating and less manufacturable; unsuitable for high-density or AOI-dependent lines | Choose only if legacy TO-277 footprint must be retained and current demand ≤3 A |
Compared with V6N3103-M3/I, the V6N3103HM3/I adds AEC-Q101 validation and tighter process controls for automotive use, while SS310H offers lower cost but sacrifices current capacity, thermal performance, and AOI compatibility-making V6N3103HM3/I optimal for new automotive and high-reliability industrial designs.

FAQ
What is the maximum junction temperature rating for the V6N3103HM3/I?
The V6N3103HM3/I has a maximum junction temperature (TJ) of +150 °C, verified per JEDEC test methods and supported by its thermal resistance profile. This rating enables reliable operation in under-hood automotive environments and thermally dense industrial modules. The V6N3103HM3/I maintains specified electrical characteristics-including 0.45 V forward voltage at 3 A-up to this limit, making it suitable for high-ambient applications where thermal headroom is constrained.
Is the V6N3103HM3/I pin-compatible with the V6N3103-M3/I?
Yes, the V6N3103HM3/I is mechanically and electrically pin-compatible with the V6N3103-M3/I-both use identical DFN33A packaging, pinout, and marking layout. The only functional difference is qualification: V6N3103HM3/I carries AEC-Q101 certification and enhanced process controls for automotive use, while V6N3103-M3/I is commercial-grade. No PCB changes are required when upgrading from V6N3103-M3/I to V6N3103HM3/I in validated designs.
Does the V6N3103HM3/I support automatic optical inspection (AOI)?
Yes, the V6N3103HM3/I features side-wettable flanks in its DFN33A package, enabling full solder-joint inspection using standard AOI systems without requiring X-ray. This capability is confirmed in Vishay's mechanical documentation and supports high-yield, zero-defect manufacturing for automotive and industrial assembly lines. The V6N3103HM3/I's matte tin plating and J-STD-002 solderability further ensure consistent AOI detection of solder fillet quality.
What is the reverse leakage current of the V6N3103HM3/I at 100 V and 125 °C?
At VR = 100 V and TJ = 125 °C, the V6N3103HM3/I exhibits a maximum reverse current (IR) of 20 mA, as specified in its official Vishay datasheet (Document Number 98543). This value reflects worst-case leakage under elevated thermal stress and remains within acceptable limits for most DC/DC and polarity protection applications. The V6N3103HM3/I's TMBS Gen3 structure helps constrain leakage growth relative to conventional Schottky diodes at high temperature.
How does the thermal resistance of the V6N3103HM3/I compare between junction-to-mount and junction-to-ambient?
The V6N3103HM3/I specifies RθJM = 3.2 °C/W (typical) and RθJA = 118 °C/W (typical, FR4, 2 oz., standard footprint). This 37× difference highlights the critical importance of thermal pad design: RθJM measures die-to-PCB-copper conduction, while RθJA includes board-level convection and conduction losses. For optimal thermal performance, the V6N3103HM3/I must be mounted on a well-designed thermal pad-its low RθJM enables efficient heat extraction when implemented correctly.
