Product details
Overview
V2NM103HM3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 100 V reverse voltage and 2.0 A average forward current, with low 0.48 V forward voltage at 1.0 A and 125 °C junction temperature, designed for high-efficiency DC/DC converters and automotive polarity protection.
For engineers reviewing the V2NM103HM3/H datasheet, V2NM103HM3/H pinout, V2NM103HM3/H application, or V2NM103HM3/H equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI compatibility, 175 °C max junction temperature, and DFN3820A footprint matching SMP (DO-220AA) mechanical outline.
Technical Context
This device implements trench MOS Schottky technology to achieve low forward voltage drop and reduced power losses versus planar Schottky diodes. Its single-cathode/anode configuration supports unidirectional conduction in low-voltage, high-frequency switching paths.
The DFN3820A package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, MSL Level 1 rating (260 °C peak reflow), and thermal resistance RθJA of 140 °C/W on FR4 PCB with 2 oz. copper.
Key Specifications

| IF(AV) | 2.0 A - continuous forward current rating at 25 °C ambient on standard PCB footprint |
| VF @ 1.0 A, 125 °C | 0.48 V - low conduction loss enabling high efficiency in thermally stressed DC/DC stages |
| IFSM | 50 A - surge current handling for transient load events like motor startup or inrush |
| TJ max | 175 °C - extended junction temperature range supporting under-hood automotive use |
| CJ | 220 pF @ 4.0 V, 1 MHz - low junction capacitance minimizing switching losses in high-frequency operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V2NM103-M3/H | Same die, identical electrical specs, but commercial-grade (non-AEC-Q101); no automotive qualification testing | Suitable for industrial or consumer DC/DC where automotive reliability not required | Select V2NM103HM3/H when AEC-Q101 compliance is mandatory; choose V2NM103-M3/H for cost-sensitive non-automotive designs |
| SS110HE3/5BT | 100 V, 1 A Schottky in SMA package; higher VF (0.85 V @ 1 A), larger footprint, no AEC-Q101 | Limited to lower-current applications; lacks side-wettable flanks and AOI support | V2NM103HM3/H offers 2× current rating, 37 % lower VF, and automotive qualification-preferred for space-constrained, high-reliability systems |
Compared with V2NM103-M3/H and SS110HE3/5BT, the V2NM103HM3/H delivers AEC-Q101 qualification, 2 A current capacity in a compact DFN3820A package with side-wettable flanks, and lowest forward voltage in its class-making it optimal for automotive and high-density power conversion where thermal performance and manufacturability are critical.

FAQ
What is the maximum junction temperature rating for the V2NM103HM3/H?
The V2NM103HM3/H has a maximum operating junction temperature of +175 °C, verified per Vishay's qualification testing and documented in the official datasheet (Document Number 98445). This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures where thermal margins are constrained. The V2NM103HM3/H maintains specified electrical parameters up to this limit, including forward voltage and leakage current.
Is the V2NM103HM3/H pin-compatible with other DFN3820A Schottky diodes?
The V2NM103HM3/H uses the standard DFN3820A package with anode and cathode terminals on opposite sides, matching industry-standard pinout for this outline. It is mechanically compatible with other DFN3820A rectifiers such as the V2NM102HM3/H and V2NM104HM3/H, though electrical ratings differ. Layout reuse is possible, but electrical validation is required due to differences in VRRM, IF(AV), and VF.
Does the V2NM103HM3/H meet automotive qualification standards?
Yes, the V2NM103HM3/H is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 98445. This qualification covers stress tests including temperature cycling, humidity bias HAST, and ESD, validating suitability for automotive powertrain, chassis, and body electronics applications where reliability under harsh conditions is mandatory.
What does the "H" in the V2NM103HM3/H part number indicate?
The "H" in V2NM103HM3/H denotes AEC-Q101 qualification grade per Vishay's internal coding system, as defined in the ordering information table of datasheet 98445. It distinguishes this variant from the commercial-grade V2NM103-M3/H (no "H"), confirming that the V2NM103HM3/H has undergone full automotive reliability testing and is approved for use in qualified automotive systems.
How does the V2NM103HM3/H compare to traditional planar Schottky diodes in terms of forward voltage?
The V2NM103HM3/H achieves 0.48 V forward voltage at 1.0 A and 125 °C, significantly lower than typical planar Schottky diodes in the same voltage class (e.g., ~0.65–0.75 V). This reduction stems from its trench MOS barrier structure, directly lowering conduction losses in high-current, high-temperature operation-critical for maintaining efficiency in compact DC/DC converters where thermal management is limited.
