Product details
Overview
V7NM63-M3/H from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 60 V reverse voltage and 7 A average forward current, with low 0.43 V forward voltage at 3.5 A and 125 °C junction temperature-optimized for high-efficiency DC/DC converters and automotive polarity protection.
For engineers reviewing the V7NM63-M3/H datasheet, V7NM63-M3/H pinout, V7NM63-M3/H application, or V7NM63-M3/H equivalent, key selection criteria include its AEC-Q101-qualified HM3 variant availability, side-wettable flanks for AOI compatibility, MSL Level 1 rating, and thermal resistance of 135 °C/W (junction-to-ambient) on FR4 PCB.
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced power loss versus planar Schottky diodes. Its single-cathode/anode configuration supports unidirectional conduction in low-voltage, high-frequency switching paths.
The DFN3820A package enables compact layout with 0.88 mm profile and solderable matte tin terminals compliant to J-STD-002 and JESD 22-B102. Thermal performance is defined per JEDEC 51-2A (RθJA) and JEDEC 51-14 (RθJM), with RθJM = 5 °C/W typical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V7NM63HM3/H | AEC-Q101 qualified; identical electrical specs and DFN3820A package; HM3 suffix denotes automotive grade | Required for automotive OEM designs needing PPAP documentation and stress test compliance | Select V7NM63HM3/H when automotive qualification is mandatory; otherwise V7NM63-M3/H suffices for commercial/industrial use |
| SS7P6L-M3/84A | Same 60 V/7 A rating but in SMP (DO-220AA) package; higher VF (0.55 V @ 3.5 A, 25 °C); no AEC-Q101 option | Larger footprint (3.5 mm × 1.9 mm vs. 3.95 mm × 2.18 mm); less suitable for ultra-dense layouts | Choose SS7P6L-M3/84A only if legacy DO-220AA footprint compatibility is required; V7NM63-M3/H offers superior thermal and space efficiency |
Compared with V7NM63HM3/H, the V7NM63-M3/H provides identical performance in commercial-grade applications without automotive qualification overhead; versus SS7P6L-M3/84A, it delivers lower forward voltage, smaller footprint, and AOI-ready packaging-making it optimal for next-gen compact, high-efficiency power designs.

FAQ
What is the maximum junction temperature rating for the V7NM63-M3/H?
The V7NM63-M3/H has a maximum operating junction temperature of +175 °C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. This rating is validated per the manufacturer's thermal characterization curves and supports continuous conduction mode operation at full 7 A load with appropriate PCB copper area.
Is the V7NM63-M3/H pin-compatible with the V7NM63HM3/H?
Yes, the V7NM63-M3/H and V7NM63HM3/H share identical DFN3820A package dimensions, pinout (anode/cathode layout), and solder pad footprint. The only difference is qualification level: HM3 denotes AEC-Q101 compliance, while M3 is commercial grade. No PCB redesign is needed when upgrading from V7NM63-M3/H to V7NM63HM3/H.
Does the V7NM63-M3/H meet automotive qualification standards?
The V7NM63-M3/H itself is commercial grade and not AEC-Q101 qualified. However, its direct variant V7NM63HM3/H carries full AEC-Q101 qualification. Both share identical electrical and thermal specifications; only the HM3 suffix indicates automotive qualification, traceability, and extended stress testing per the AEC standard.
What is the forward voltage of the V7NM63-M3/H at 7 A and 125 °C?
The V7NM63-M3/H exhibits a maximum forward voltage of 0.57 V at 7 A and 125 °C, per the Electrical Characteristics table. At the same conditions, the typical value is 0.52 V. This low VF directly reduces conduction losses in high-current DC/DC outputs, improving overall system efficiency and thermal margin.
Can the V7NM63-M3/H be used in high-frequency switching applications above 500 kHz?
Yes, the V7NM63-M3/H is optimized for high-frequency operation, with a junction capacitance of 1060 pF at 4 V and 1 MHz, and fast recovery characteristics inherent to TMBS® technology. It is routinely deployed in 1 MHz DC/DC converters and 20–100 kHz motor drive freewheeling paths, where low stored charge minimizes switching loss and EMI.
