Product details
Overview
V5NM63HM3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 60 V repetitive peak reverse voltage and 5 A average forward current at infinite heatsink, with low 0.43 V forward voltage at 2.5 A and 125 °C junction temperature-used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V5NM63HM3/I datasheet, V5NM63HM3/I pinout, V5NM63HM3/I application, or V5NM63HM3/I equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI compatibility, 175 °C max junction temperature, and thermal resistance of 135 °C/W (junction-to-ambient, FR4, 2 oz).
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced power losses versus planar Schottky diodes. Its single-cathode/anode configuration supports unidirectional conduction in high-frequency switching topologies where fast recovery and low IR are critical.
The DFN3820A package enables compact PCB layouts with solderable matte tin terminals compliant to J-STD-002 and JESD 22-B102, while meeting MSL Level 1 and JESD 201 Class 2 whisker test requirements-essential for automotive and industrial reflow processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V5NM63-M3/I | Same die, identical electrical specs, but industry-grade (non-AEC-Q101); no automotive qualification testing | Suitable for commercial/industrial DC/DC converters where automotive reliability is not required | Select V5NM63-M3/I for cost-sensitive non-automotive designs needing identical performance without qualification overhead |
| SS5P6HM3/H | 5 A, 60 V Schottky in SMP (DO-220AA) package; slightly higher VF (0.55 V typ. @ 2.5 A, 25 °C); no side-wettable flanks | Compatible footprint but different thermal and AOI characteristics; less suitable for high-volume automotive SMT lines | Choose SS5P6HM3/H only if legacy DO-220AA board layout must be retained and AOI is not required |
Compared with V5NM63HM3/I, V5NM63-M3/I offers identical electrical performance at lower cost for non-automotive use, while SS5P6HM3/H provides mechanical compatibility with SMP-based designs but lacks AOI support and has higher conduction loss.

FAQ
What is the maximum junction temperature rating for V5NM63HM3/I?
The V5NM63HM3/I has a maximum junction temperature (TJ) of +175 °C, enabling reliable operation in under-hood automotive environments and high-temperature industrial enclosures. This rating is validated per AEC-Q101 stress tests and confirmed in the Vishay datasheet revision 06-Nov-2024. Derating curves in Figure 1 show usable current vs. mount temperature, with thermal resistance RθJM = 5 °C/W to the cathode pad.
Is V5NM63HM3/I compatible with automated optical inspection (AOI)?
Yes, V5NM63HM3/I features side-wettable flanks in its DFN3820A package, allowing visual and optical inspection of solder fillets without X-ray. This design meets IPC-A-610 Class 2/3 requirements and is explicitly cited in the Vishay datasheet as "suitable for customer AOI." The matte tin plating and defined flank geometry ensure consistent reflectivity and contrast for machine vision systems.
How does V5NM63HM3/I differ from V5NM63-M3/I?
V5NM63HM3/I and V5NM63-M3/I share identical electrical specifications-including VRRM = 60 V, IF(AV) = 5 A, and VF = 0.43 V @ 2.5 A/125 °C-but differ in qualification: V5NM63HM3/I carries AEC-Q101 certification for automotive use, while V5NM63-M3/I is commercial-grade. Both use the same DFN3820A package and halogen-free, RoHS-compliant construction.
What is the thermal resistance junction-to-ambient for V5NM63HM3/I on FR4?
The thermal resistance junction-to-ambient (RθJA) for V5NM63HM3/I is 135 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended footprint per Vishay document 98439. This value assumes natural convection and is measured per JEDEC 51-2A. For forced airflow or enhanced copper planes, actual RθJA may improve significantly.
Does V5NM63HM3/I have a polarity marking, and how is it identified?
Yes, V5NM63HM3/I uses a color band to denote the cathode end, consistent with industry-standard diode marking conventions. The band is located adjacent to the cathode terminal on the DFN3820A package body. This marking is visible after placement and aligns with the pinout diagram in the Vishay datasheet, where "K" is labeled next to the banded side.
