Product details
Overview
V5NM103HM3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 100 V repetitive peak reverse voltage and 5 A average forward current, with 0.49 V forward voltage at 2.5 A and 125 °C junction temperature-optimized for DC/DC converters and automotive polarity protection.
For engineers reviewing the V5NM103HM3/H datasheet, V5NM103HM3/H pinout, V5NM103HM3/H application, or V5NM103HM3/H equivalent, key selection criteria include its AEC-Q101 qualification, low-profile side-wettable DFN3820A footprint, 175 °C max junction temperature, and 580 pF junction capacitance at 4.0 V/1 MHz-critical for high-frequency switching efficiency and AOI-compatible assembly.
Technical Context
The V5NM103HM3/H 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 freewheeling and reverse-polarity protection paths.
Thermally, it features RθJM = 5 °C/W (typical) and RθJA = 135 °C/W (JEDEC 51-2A, FR4, 2 oz.), enabling high-power-density designs. The device meets MSL Level 1 and JESD 201 Class 2 whisker resistance, with matte tin-plated terminals solderable per J-STD-002.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V5NM103-M3/H | Same die, identical electrical specs, but commercial-grade (non-AEC-Q101); no automotive qualification testing | Not suitable for automotive production; acceptable for industrial or consumer DC/DC where qualification not mandated | Select V5NM103-M3/H only when AEC-Q101 is not required and cost optimization is prioritized |
| SS5P10HM3/H | 5 A, 100 V Schottky in SMP (DO-220AA) package; VF = 0.55 V @ 5 A, 25 °C; higher RθJA (~180 °C/W) | Larger footprint, less thermally efficient, but offers through-hole compatibility and higher creepage | Choose SS5P10HM3/H only if board-level creepage/safety spacing or legacy DO-220AA layout reuse is mandatory |
Compared with V5NM103-M3/H and SS5P10HM3/H, the V5NM103HM3/H uniquely combines AEC-Q101 qualification, DFN3820A's ultra-low profile and side-wettable flanks, and best-in-class thermal resistance (RθJM = 5 °C/W), making it optimal for next-generation automotive power modules where space, reliability, and AOI yield are critical.

FAQ
What is the maximum junction temperature rating for the V5NM103HM3/H?
The V5NM103HM3/H has a maximum junction temperature (TJ max.) of +175 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet (fig. 1) define allowable IF(AV) versus mount temperature, with full 5 A rated at ≤75 °C mount temperature under infinite heatsink conditions. The V5NM103HM3/H must be thermally anchored to adequate PCB copper area to maintain this limit in real-world layouts.
Is the V5NM103HM3/H pin-compatible with other DFN3820A Schottky rectifiers?
Yes-the V5NM103HM3/H uses the standardized DFN3820A outline (3.95 mm × 2.18 mm) with anode and cathode terminals positioned per JEDEC MO-229 variation. It shares identical pad layout and side-wettable flank geometry with other Vishay DFN3820A rectifiers like V5NM603HM3/H. However, electrical parameters-including VF, IR, and IFSM-differ across voltage/current ratings, so direct substitution requires verification of circuit-level stress margins. The V5NM103HM3/H itself is not a drop-in replacement for higher-voltage variants.
Does the V5NM103HM3/H meet automotive qualification standards?
Yes-the "HM3" suffix explicitly denotes AEC-Q101 qualification. The V5NM103HM3/H has passed all required stress tests including HTGB, HTRB, TCT, UHAST, and mechanical shock per AEC-Q101 Rev G. It is approved for use in automotive powertrain, chassis, and body electronics where high reliability and extended temperature operation are mandatory. Documentation of test reports is available upon request for the V5NM103HM3/H.
What is the forward voltage specification of the V5NM103HM3/H at operating conditions?
The V5NM103HM3/H specifies VF = 0.49 V at IF = 2.5 A and TJ = 125 °C, and VF = 0.58 V at IF = 5 A and TJ = 125 °C. At room temperature (25 °C), VF is 0.56 V (typ.) at 2.5 A and 0.67 V (max.) at 5 A. These values reflect actual conduction loss under real thermal conditions-critical for calculating efficiency and thermal rise in DC/DC designs using the V5NM103HM3/H.
How does the side-wettable flank design benefit manufacturing of the V5NM103HM3/H?
The side-wettable flanks on the V5NM103HM3/H enable full 100% automated optical inspection (AOI) of solder fillet quality without requiring X-ray or cross-section analysis. During reflow, molten solder wets vertically along the flank edges, creating a visible meniscus detectable by standard AOI systems. This eliminates hidden voids or insufficient wetting-common failure modes in leadless packages-and improves first-pass yield in high-volume automotive production lines deploying the V5NM103HM3/H.
