Product details
Overview
V7N3L63-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN33A package, rated for 60 V repetitive peak reverse voltage, 7 A average forward current, and 120 A surge capability. It delivers low forward voltage (0.37 V at 3.5 A, 125 °C), ultra-low leakage, and operates up to 150 °C junction temperature - optimized for DC/DC converters and polarity protection in space-constrained power stages.
For engineers reviewing the V7N3L63-M3/I datasheet, V7N3L63-M3/I pinout, V7N3L63-M3/I application, or V7N3L63-M3/I equivalent, key selection criteria include its Gen3 TMBS low-leakage performance, side-wettable DFN33A footprint for AOI compatibility, MSL-1 rating, and halogen-free RoHS-compliant construction - critical for high-efficiency, automotive-qualified (HM3 variant) and industrial power designs.
Technical Context
This single-anode Schottky rectifier uses Vishay's third-generation TMBS technology to achieve sub-0.4 V forward drop at elevated temperatures while suppressing reverse leakage to ≤13 mA at 60 V and 125 °C. Its DFN33A package integrates four anode terminals sharing one cathode, enabling parallel conduction paths within a 3.4 mm × 3.2 mm footprint.
The device is thermally characterized with RθJM = 2.9 °C/W (junction-to-mount) and RθJA = 118 °C/W (on FR4, 2 oz., standard pad), supporting high-current operation under constrained thermal conditions. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V7N3L63HM3/I | AEC-Q101 qualified; identical electrical specs but validated for automotive temperature cycling and humidity testing | Required for Tier-1 automotive modules; not necessary for commercial/industrial use | Select HM3 only when automotive qualification documentation (PPAP, test reports) is mandatory |
| SS7P6L-M3/84A | Same DFN33A package, 60 V VRRM, but Gen2 TMBS - higher IR (≤25 mA @ 125 °C) and VF (0.42 V @ 3.5 A, 125 °C) | Acceptable for cost-sensitive non-automotive applications where leakage <15 mA is sufficient | Choose SS7P6L-M3/84A only if thermal budget allows +0.05 V VF penalty and leakage tolerance is relaxed |
Compared with V7N3L63-M3/I, the HM3 variant adds automotive qualification without electrical trade-offs, while SS7P6L-M3/84A offers lower cost at the expense of leakage and forward drop - making V7N3L63-M3/I optimal for thermally demanding, high-reliability industrial and computing power supplies.

FAQ
What is the maximum operating junction temperature for V7N3L63-M3/I?
The V7N3L63-M3/I has a maximum junction temperature (TJ max.) of +150 °C, verified per JEDEC standards. This rating enables reliable operation in sealed enclosures or high-ambient environments such as automotive engine bays or industrial motor drives. Derating curves in the datasheet (Fig. 1) define safe IF(AV) limits at elevated case temperatures. The V7N3L63-M3/I must be thermally anchored to adequate PCB copper area to maintain TJ ≤ 150 °C under full load.
Does V7N3L63-M3/I support automatic optical inspection (AOI)?
Yes, the V7N3L63-M3/I uses a DFN33A package with side-wettable flanks, explicitly designed for full-spectrum AOI coverage of solder fillets. Vishay confirms this feature in the mechanical data section and notes compatibility with standard AOI systems without requiring X-ray verification. The V7N3L63-M3/I's matte tin-plated terminals and controlled coplanarity further ensure consistent solder joint detection during automated manufacturing.
How does V7N3L63-M3/I differ from the HM3 version?
The V7N3L63-M3/I is the commercial-grade variant, while V7N3L63HM3/I adds AEC-Q101 qualification - including extended temperature cycling, humidity testing, and failure analysis per automotive stress requirements. Electrically, both share identical VRRM, IF(AV), VF, and thermal specs. The V7N3L63-M3/I is suitable for industrial and computing applications; only the HM3 suffix guarantees automotive compliance documentation and test reports.
What is the thermal resistance from junction to mount (RθJM) for V7N3L63-M3/I?
The V7N3L63-M3/I has a typical RθJM of 2.9 °C/W, measured per JEDEC 51-14 TDIM methodology. This value reflects direct thermal conduction from the die to the PCB mounting pad through the cathode terminal - critical for thermal modeling in multi-layer boards with internal thermal planes. The V7N3L63-M3/I achieves this low RθJM via its large cathode pad and optimized die attach structure, enabling efficient heat extraction without external heatsinks.
Is V7N3L63-M3/I halogen-free and RoHS-compliant?
Yes, the "M3" suffix in V7N3L63-M3/I denotes halogen-free, RoHS-compliant construction per IEC 61249-2-21 and JEDEC JS709E. Vishay certifies that all materials - molding compound, die attach, and matte tin plating - meet strict halogen thresholds (<900 ppm Cl, <900 ppm Br, <1500 ppm total halogens) and RoHS substance restrictions. The V7N3L63-M3/I is fully compliant for sale in EU, China, Korea, and other regulated markets.
