Product details
Overview
V5N103HM3/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 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/H datasheet, V5N103HM3/H pinout, V5N103HM3/H application, or V5N103HM3/H equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable DFN3820A footprint for AOI compatibility, 150 °C max junction temperature, and 560 pF junction capacitance at 4.0 V - all critical for space-constrained, thermally demanding automotive and industrial power designs.
Technical Context
The V5N103HM3/H employs trench MOS Schottky technology to achieve low forward voltage drop and reduced switching 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 (typical, FR4, 2 oz., standard footprint), enabling operation up to 150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 with 260 °C peak reflow profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V reverse voltage without breakdown, suitable for 48 V system bus protection |
| IF(AV) | 5 A - delivers continuous 5 A forward current with infinite heatsink; derates to 2 A in free air on FR4 |
| VF @ 2.5 A, 125 °C | 0.46 V - enables low conduction loss in high-temp environments like under-hood automotive modules |
| IFSM | 100 A - withstands short-duration surge currents (8.3 ms half-sine), supporting robust start-up and fault handling |
| TJ max. | 150 °C - allows operation in high-ambient environments such as engine control units and industrial motor drives |
| CJ @ 4.0 V, 1 MHz | 560 pF - limits capacitive loading in high-frequency switching nodes of synchronous buck converters |
| RθJA (FR4, 2 oz.) | 135 °C/W - defines thermal limit for PCB-level heat dissipation without external heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS5L100S | Same 100 V VRRM and 5 A IF(AV), but TO-277A package (higher RθJA ≈ 200 °C/W); VF = 0.55 V @ 5 A, 25 °C | Larger footprint and lower thermal efficiency; not AEC-Q101 qualified | Prefer V5N103HM3/H for space-constrained, automotive-qualified designs requiring AOI support |
| ON Semi NRVB5100CTT1G | 5 A/100 V dual common-cathode Schottky in SMC package; VF = 0.75 V @ 5 A, 25 °C; no AEC-Q101 grade | Dual configuration enables dual-rail protection but increases board area; higher VF raises conduction loss | Choose V5N103HM3/H when single-diode, low-Z-height, and automotive qualification are mandatory |
Compared with STPS5L100S and NRVB5100CTT1G, the V5N103HM3/H delivers superior thermal performance in minimal area, AEC-Q101 validation for automotive use, and lower forward voltage at elevated temperature - making it optimal for next-generation compact, high-reliability power rails.

FAQ
What is the maximum junction temperature rating for V5N103HM3/H?
The V5N103HM3/H has a maximum junction temperature (TJ max.) of +150 °C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Thermal design must ensure that power dissipation stays within limits defined by RθJA = 135 °C/W (typical) and RθJM = 5 °C/W (typical) to prevent exceeding this threshold during continuous operation of the V5N103HM3/H.
Is V5N103HM3/H pin-compatible with other DFN3820A Schottky diodes?
The V5N103HM3/H uses the standard DFN3820A outline with cathode (K) and anode (A) terminals on opposite sides - matching mechanical and pad layout of industry-standard DFN3820A rectifiers. However, electrical characteristics (e.g., VF, IFSM, CJ) differ across vendors; direct substitution requires validation of thermal and dynamic performance in the target circuit. The V5N103HM3/H is not guaranteed pin-compatible with non-Vishay DFN3820A parts unless explicitly confirmed by cross-reference data.
Does V5N103HM3/H meet automotive qualification standards?
Yes, the V5N103HM3/H carries the HM3 suffix, indicating full AEC-Q101 qualification per Rev G. It has passed stress tests including HTGB, HTRB, TC, and ESD (HBM ≥ 2 kV). This makes the V5N103HM3/H suitable for automotive applications such as body electronics, infotainment power supplies, and ADAS sensor modules where component-level reliability is mandated.
What is the forward voltage specification of V5N103HM3/H at elevated temperature?
The V5N103HM3/H specifies VF = 0.46 V at IF = 2.5 A and TJ = 125 °C - a key parameter for thermal-aware design. At TJ = 25 °C and IF = 2.5 A, VF is 0.52 V (typical). This positive temperature coefficient helps balance current sharing in parallel configurations and reduces thermal runaway risk. Engineers should reference the V5N103HM3/H datasheet curves (Fig. 3) for VF interpolation across the full -40 °C to +150 °C range.
How does the side-wettable flank feature benefit manufacturing of V5N103HM3/H?
The side-wettable flanks on the V5N103HM3/H's DFN3820A package enable reliable solder joint inspection using standard Automatic Optical Inspection (AOI) systems - eliminating the need for costly X-ray verification. This improves first-pass yield in high-volume SMT lines and supports IPC-A-610 Class 2/3 compliance. The V5N103HM3/H's flanks are matte tin-plated and solderable per J-STD-002 and JESD 22-B102, ensuring robust process compatibility.
