Product details

Overview

V2N103-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN3820A package, rated for 100 V reverse voltage and 2.0 A average forward current, with low 0.45 V forward voltage at 1.0 A and 125 °C junction temperature-optimized for DC/DC converters and polarity protection in space-constrained power stages.

For engineers reviewing the V2N103-M3/I datasheet, V2N103-M3/I pinout, V2N103-M3/I application, or V2N103-M3/I equivalent, key selection criteria include its MSL Level 1 rating, side-wettable flanks for AOI compatibility, AEC-Q101-qualified variant availability (V2N103HM3/I), and thermal resistance of 140 °C/W (junction-to-ambient) on standard FR4 PCB.

Technical Context

The V2N103-M3/I implements trench MOS Schottky technology to achieve low forward voltage drop and high switching efficiency at high frequencies, eliminating minority-carrier recovery losses typical of PN junction diodes. Its single-anode/cathode configuration supports unidirectional conduction in low-voltage (<100 V) power rails.

Designed for surface-mount assembly on 10 mm × 10 mm copper pads, it delivers 1.6 A average forward current under free-air conditions (FR4, 2 oz. copper) and sustains 50 A non-repetitive surge current per JESD22-A112. Thermal performance is governed by R_θJA = 140 °C/W and R_θJM = 6 °C/W, enabling operation up to +150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking capability without breakdown in polarity-protection or freewheeling paths.
I_F(AV)	2.0 A (at 10 mm × 10 mm Cu pad) - Continuous DC output current handling in DC/DC converter outputs.
V_F @ 1.0 A, 125 °C	0.45 V - Low conduction loss enabling >92% efficiency in 5–24 V input buck converters.
I_FSM	50 A - Surge current tolerance for inrush or fault events in automotive body-control modules.
R_θJA	140 °C/W - Junction-to-ambient thermal resistance on standard FR4 PCB, defining heatsinking requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
V2N103HM3/I	AEC-Q101 qualified; identical electrical specs but enhanced reliability testing for automotive use.	Required for under-hood ECUs, body controllers, and ADAS power supplies meeting ISO/TS 16949.	Select when automotive qualification is mandatory; otherwise V2N103-M3/I suffices for industrial/commercial designs.
SS210H-LTP	DO-220AA (SMP) package; 100 V/2 A rating; VF = 0.55 V @ 1 A, 25 °C; higher R_θJA = 190 °C/W.	Better suited for through-hole prototyping or legacy board upgrades where DFN rework is impractical.	Choose for manual assembly or mixed-technology boards; avoid where thermal performance or AOI is critical.

Compared with V2N103HM3/I, the V2N103-M3/I offers identical electrical performance at lower cost and qualification overhead, while SS210H-LTP trades compactness and thermal efficiency for mechanical robustness and assembly flexibility-making each optimal for distinct design constraints.

FAQ

What is the maximum junction temperature rating for the V2N103-M3/I?

The V2N103-M3/I has a maximum junction temperature (T_J) of +150 °C, validated per JEDEC standards. This rating allows sustained operation in high-ambient environments such as automotive engine bays or enclosed industrial power supplies. Derating curves in the datasheet confirm 2.0 A I_F(AV) is maintained up to +125 °C ambient when mounted on a 10 mm × 10 mm copper pad-critical for thermal design validation of the V2N103-M3/I.

Does the V2N103-M3/I have side-wettable flanks for AOI inspection?

Yes, the V2N103-M3/I uses the DFN3820A package with side-wettable flanks, explicitly designed for automatic optical inspection (AOI) of solder joints without requiring X-ray. This feature is confirmed in the Vishay datasheet revision 06-Nov-2024 (Document Number: 98441), and ensures high-yield, low-defect SMT assembly-especially valuable in consumer electronics and IoT device production where the V2N103-M3/I is commonly deployed.

Is the V2N103-M3/I RoHS-compliant and halogen-free?

Yes, the "M3" suffix in V2N103-M3/I denotes halogen-free, RoHS-compliant construction with matte tin-plated terminals compliant with J-STD-002 and JESD22-B102. The molding compound meets UL 94 V-0 flammability rating, and whisker resistance is certified to JESD201 Class 2-making the V2N103-M3/I suitable for environmentally regulated markets including EU, Japan, and North America.

What is the thermal resistance junction-to-ambient (R_θJA) for the V2N103-M3/I?

The V2N103-M3/I has a typical R_θJA of 140 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and a 10 mm × 10 mm thermal pad, per JEDEC 51-2A. Its maximum R_θJA is 175 °C/W under less optimal layout conditions. This value directly determines allowable power dissipation-e.g., at 0.45 V_F and 1.0 A, the V2N103-M3/I dissipates 0.45 W and rises ~63 °C above ambient, defining safe operating margins.

How does the V2N103-M3/I differ from the AEC-Q101 qualified version?

The V2N103HM3/I is the AEC-Q101 qualified variant of the same die and package, differing only in extended reliability testing (temperature cycling, HTRB, UHAST) and automotive-grade traceability-not electrical specs. The V2N103-M3/I shares identical V_RRM, I_F(AV), V_F, and thermal parameters but targets commercial/industrial use. Both use the same DFN3820A footprint, enabling BOM flexibility where qualification isn't mandated-key for scalable V2N103-M3/I deployment.
