Product details
Overview
V2N103HM3/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 0.45 V forward voltage at 1.0 A and 125 °C junction temperature. It serves as a high-efficiency freewheeling or polarity protection diode in automotive-grade DC/DC converters and low-voltage inverters.
For engineers reviewing the V2N103HM3/H datasheet, V2N103HM3/H pinout, V2N103HM3/H application, or V2N103HM3/H equivalent, key selection factors include its AEC-Q101 qualification, side-wettable DFN3820A footprint for AOI compatibility, 150 °C max junction temperature, and verified 50 A surge rating - critical for under-hood power conversion reliability.
Technical Context
This device implements trench MOS Schottky technology to achieve lower forward voltage and reduced switching losses versus planar Schottky diodes. Its single-anode/cathode configuration operates with no minority-carrier storage, enabling zero reverse recovery charge and high-frequency operation up to several MHz in DC/DC topologies.
The DFN3820A package delivers thermal resistance of 6 °C/W junction-to-mount and 140 °C/W junction-to-ambient (JEDEC 51-2A), supporting high-power-density layouts on 2 oz. copper PCBs. The matte tin-plated terminals meet J-STD-002 solderability and JESD 22-B102 whisker testing Class 2.
Key Specifications
| Parameter | Value and Actual 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 |
|---|---|---|---|
| STPS2L100HF | Same 100 V / 2 A rating but TO-277A package (higher RθJA = 200 °C/W); VF = 0.52 V @ 1 A, 125 °C | Not AEC-Q101 qualified; lacks side-wettable flanks and MSL Level 1 reflow support | Preferred for cost-sensitive industrial designs where AOI and automotive qualification are not required |
| ON Semi NRVB20100CTT4G | 20 A dual common-cathode part in TO-220AC; VF = 0.72 V @ 10 A, 125 °C; higher capacitance (450 pF) | Through-hole, higher profile (9.2 mm), unsuitable for space-constrained SMT layouts | Used when parallel devices or higher surge current (>50 A) is needed, but incompatible with DFN3820A footprint |
Compared with STPS2L100HF and NRVB20100CTT4G, V2N103HM3/H uniquely combines AEC-Q101 qualification, side-wettable DFN3820A packaging, and lowest VF at elevated temperature - making it the only option for automotive SMT power conversion where thermal density, AOI compliance, and transient robustness are jointly critical.

FAQ
What is the maximum junction temperature rating for V2N103HM3/H?
The V2N103HM3/H has a maximum junction temperature (TJ) rating of +150 °C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments where ambient temperatures reach 125 °C, provided thermal design maintains dPD/dTJ < 1/RθJA. Derating curves in the V2N103HM3/H datasheet confirm 1.6 A IF(AV) capability at 100 °C mount temperature.
Is V2N103HM3/H compatible with standard reflow soldering processes?
Yes, V2N103HM3/H meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, allowing use with industry-standard lead-free reflow profiles without pre-baking. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 Class 2 whisker testing, ensuring long-term solder joint integrity in production lines.
How does the DFN3820A package of V2N103HM3/H support automated optical inspection?
The DFN3820A package of V2N103HM3/H features side-wettable flanks - exposed metal on the package edges that form visible solder fillets during reflow. This enables full coverage AOI without X-ray, verifying solder volume, alignment, and wetting quality. The V2N103HM3/H datasheet explicitly states this feature is designed for customer AOI compatibility in high-reliability manufacturing.
What is the reverse leakage current of V2N103HM3/H at 100 V and 125 °C?
At VR = 100 V and TJ = 125 °C, the V2N103HM3/H exhibits a maximum reverse current (IR) of 8.0 mA, as specified in the Electrical Characteristics table. This value is critical for low-power standby modes in DC/DC converters, where leakage directly impacts quiescent current and battery drain in automotive always-on systems.
Does V2N103HM3/H have a documented thermal resistance junction-to-mount (RθJM) value?
Yes, the V2N103HM3/H datasheet specifies a typical RθJM of 6 °C/W, measured per JEDEC 51-14 TDIM method. This parameter quantifies heat transfer from die to the PCB copper mount pad and is essential for modeling thermal performance in thermally constrained modules - for example, predicting 12 °C temperature rise at 2 W dissipation using the V2N103HM3/H in a properly designed layout.
