Product details
Overview
V7N3M63-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN33A package, rated for 60 V reverse voltage, 7 A average forward current, and 120 A surge capability, with low 0.43 V forward voltage at 3.5 A and 125 °C junction temperature-used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V7N3M63-M3/I datasheet, V7N3M63-M3/I pinout, V7N3M63-M3/I application, or V7N3M63-M3/I equivalent, key selection criteria include its TMBS Gen3 ultra-low leakage, side-wettable DFN33A footprint for AOI compatibility, AEC-Q101-qualified variant availability, and thermal resistance of 2.9 °C/W junction-to-mount.
Technical Context
This device implements a single-anode, four-terminal cathode configuration in a compact DFN33A package, enabling high-current conduction through parallel anode paths while maintaining low thermal resistance (RθJM = 2.9 °C/W). Its TMBS Gen3 architecture delivers <0.015 mA reverse leakage at 60 V and 25 °C, and <2.5 mA at 125 °C.
The rectifier operates across -40 to +175 °C junction temperature range, supports 260 °C peak reflow per J-STD-020 MSL Level 1, and achieves 1060 pF typical junction capacitance at 4.0 V and 1 MHz-optimized for high-frequency switching in space-constrained power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V7N3M63HM3/I | AEC-Q101 qualified; identical electrical specs but validated for automotive temperature cycling and humidity testing | Required for automotive infotainment power rails and ADAS camera modules | Select when automotive qualification and traceable lot documentation are mandatory |
| SS7P6M (ON Semiconductor) | Same 60 V / 7 A rating but TO-277 package; higher RθJA (150 °C/W), no side-wettable flanks | Suitable for manual assembly or legacy layouts where DFN rework is impractical | Choose only if board-level AOI is unavailable or thermal interface to heatsink is preferred over PCB copper spread |
Compared with V7N3M63-M3/I, the V7N3M63HM3/I offers identical performance with added automotive reliability validation, while SS7P6M trades compact DFN integration and AOI support for through-hole-compatible packaging and simpler thermal management via external heatsinking.

FAQ
What is the maximum junction temperature rating for the V7N3M63-M3/I?
The V7N3M63-M3/I has a maximum junction temperature (TJ max.) of +175 °C, enabling operation in demanding environments such as automotive engine compartments or industrial motor drives where ambient temperatures exceed 125 °C. This rating is validated per JEDEC standards and supported by its DFN33A package thermal design.
Does the V7N3M63-M3/I have AEC-Q101 qualification?
The V7N3M63-M3/I itself is the commercial-grade version; however, the pin-identical V7N3M63HM3/I variant carries full AEC-Q101 qualification. Both share identical electrical characteristics and DFN33A mechanical form factor, differing only in test documentation and lot traceability for automotive use cases.
How does the side-wettable flank feature benefit manufacturing of the V7N3M63-M3/I?
The side-wettable flanks on the V7N3M63-M3/I's DFN33A package allow automatic optical inspection (AOI) systems to verify solder fillet quality without requiring X-ray imaging. This reduces final-test cost and improves first-pass yield in high-volume SMT lines producing power supplies and motor controllers.
What is the thermal resistance junction-to-mount (RθJM) for the V7N3M63-M3/I?
The V7N3M63-M3/I has a typical RθJM of 2.9 °C/W, measured per JEDEC 51-14 TDIM method. This low value reflects efficient heat transfer from the die directly into the PCB copper mount pad, making it suitable for thermally dense layouts where heatsinks are impractical.
Can the V7N3M63-M3/I replace traditional through-hole Schottky diodes in existing designs?
Direct replacement of through-hole diodes with the V7N3M63-M3/I requires PCB layout revision due to its DFN33A surface-mount footprint and four-terminal configuration. While electrical ratings align with many TO-277 devices (e.g., SS7P6M), the V7N3M63-M3/I demands updated stencil design and AOI setup for reliable assembly.
