Product details
Overview
V5N103HM3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 100 V reverse voltage and 5 A average forward current, with low 0.46 V forward voltage at 2.5 A and 125 °C junction temperature-designed for high-efficiency DC/DC converters and automotive polarity protection.
For engineers reviewing the V5N103HM3/I datasheet, V5N103HM3/I pinout, V5N103HM3/I application, or V5N103HM3/I equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI compatibility, 150 °C max junction temperature, and thermal resistance RθJA of 135 °C/W on FR4 PCB.
Technical Context
The V5N103HM3/I employs trench MOS Schottky technology to achieve low forward voltage and reduced power losses versus planar Schottky diodes. Its single-cathode/anode configuration supports unidirectional conduction in compact, low-profile layouts where thermal management and space constraints are critical.
Designed for automotive-grade reliability, it meets JESD201 Class 2 whisker testing and MSL Level 1 per J-STD-020 with 260 °C peak reflow. The DFN3820A package enables high-density mounting while maintaining robust solder joint inspection via side-wettable flanks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V reverse voltage without breakdown in freewheeling or polarity protection circuits |
| IF(AV) | 5 A - delivers continuous 5 A forward current with infinite heatsink; derates to 2 A in free-air FR4 mounting |
| VF @ 2.5 A, 125 °C | 0.46 V - enables high efficiency in high-temperature DC/DC stages by minimizing conduction loss |
| IFSM | 100 A - withstands short-duration surge currents during startup or fault conditions in inverters |
| TJ max. | 150 °C - supports operation in under-hood automotive environments and thermally constrained industrial modules |
| RθJA | 135 °C/W - defines thermal limit for PCB-level cooling design when mounted on 2 oz. FR4 with standard footprint |
| CJ | 560 pF @ 4 V, 1 MHz - impacts high-frequency switching noise and EMI in >100 kHz converter topologies |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V5N103-M3/I | 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 V5N103HM3/I when AEC-Q101 compliance is mandatory; choose V5N103-M3/I for cost-sensitive non-automotive designs |
| SS510H-LTP | 5 A / 100 V Schottky in SMA package; VF = 0.75 V @ 5 A, 25 °C; RθJA ≈ 65 °C/W; no AEC-Q101 | Larger footprint, higher VF, better thermal dissipation via leads; unsuitable for ultra-thin or high-density layouts | V5N103HM3/I offers superior space efficiency and thermal performance in DFN; SS510H-LTP preferred only if leaded package is required for manual repair or legacy layout |
Compared with V5N103-M3/I and SS510H-LTP, the V5N103HM3/I uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and lowest VF in its class-making it optimal for next-gen automotive power modules where size, thermal headroom, and process validation are jointly constrained.

FAQ
What is the maximum junction temperature rating for the V5N103HM3/I?
The V5N103HM3/I has a maximum junction temperature (TJ max.) of +150 °C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and thermally dense industrial power modules. Derating curves in the datasheet show usable current drops to 2 A at 100 °C ambient on standard FR4, confirming thermal design margins for V5N103HM3/I in real-world layouts.
Is the V5N103HM3/I pin-compatible with other DFN3820A Schottky diodes?
The V5N103HM3/I uses the standard DFN3820A outline with two terminals: anode and cathode. While physical footprint matches other DFN3820A devices, electrical characteristics-including VF, IFSM, and CJ-are unique to the V5N103HM3/I die. Substitution requires verification of all parameters and thermal performance; no generic pin-compatibility claim is made for V5N103HM3/I beyond mechanical fit.
Does the V5N103HM3/I require special PCB layout considerations?
Yes-the V5N103HM3/I relies on its exposed cathode pad for thermal conduction. Recommended layout includes ≥20 mm² copper pour connected to internal ground plane via ≥4 thermal vias (0.3 mm diameter). Keep traces short and wide on both anode and cathode sides to minimize inductance, especially in >200 kHz applications where V5N103HM3/I's 560 pF capacitance interacts with parasitic L.
What does the "HM3" suffix indicate in V5N103HM3/I?
In V5N103HM3/I, "H" denotes AEC-Q101 qualification, "M3" indicates halogen-free, RoHS-compliant, lead-free termination meeting JESD201 Class 2 whisker resistance, and "I" specifies 13″ tape-and-reel packaging (14,000 units per reel). This distinguishes V5N103HM3/I from commercial-grade V5N103-M3/I and confirms full automotive process validation for V5N103HM3/I.
How does the V5N103HM3/I perform at elevated temperatures?
The V5N103HM3/I maintains low forward voltage-0.46 V at 2.5 A and 125 °C-demonstrating superior thermal stability over conventional Schottky diodes. Its reverse leakage remains within spec (≤5 mA at 100 V, 125 °C), and junction-to-mount thermal resistance (RθJM = 5 °C/W) ensures efficient heat transfer to the PCB, making V5N103HM3/I well-suited for sustained high-temperature operation in automotive and industrial settings.
