Product details
Overview
V9N3202-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN33A package, rated for 200 V reverse voltage, 9 A average forward current, and 150 A surge capability, with low 0.60 V forward voltage at 4.5 A and 125 °C junction temperature - used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V9N3202-M3/I datasheet, V9N3202-M3/I pinout, V9N3202-M3/I application, or V9N3202-M3/I equivalent, this page delivers verified electrical specs, thermal resistance data (RθJA = 118 °C/W), AEC-Q101-qualified variant availability, and real-world design implications for high-efficiency, low-profile power rectification.
Technical Context
The V9N3202-M3/I employs trench MOS barrier technology to achieve lower forward voltage and higher switching efficiency than planar Schottky diodes, enabling operation up to 175 °C junction temperature. Its single-anode, four-terminal DFN33A layout supports parallel anode connections for current sharing while maintaining low thermal resistance (RθJM = 2.9 °C/W).
Designed for high-frequency, low-voltage power conversion, it delivers 500 pF junction capacitance at 4.0 V and 1 MHz, minimizing switching losses. The device meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker test requirements, with matte tin-plated side-wettable flanks for automated optical inspection (AOI) compatibility.
Key Specifications

|---|---|
|
Use Scenario: Secondary-side synchronous rectification in isolated 12 V → 3.3 V/5 V buck-derived converters for server VRMs and telecom PSUs.

IC Role / Device Role / Timing Role: Unidirectional current valve preventing damage during incorrect connector insertion or supply backfeeding. Use Value: 200 V VRRM provides 2× margin over 48 V nominal systems; 150 A IFSM survives accidental 12 V short-to-battery events. |
| Freewheeling Diodes | Low-Voltage Inverters |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V9N2020-M3/I | 200 V VRRM, 20 A IF(AV), larger DFN50A package (5.0 mm × 5.0 mm), RθJA = 65 °C/W | Better thermal performance for sustained 15–20 A loads; not suitable for space-constrained 3.4 mm × 3.4 mm footprints | Select when board area allows and average current exceeds 12 A; requires revised thermal pad and stencil design |
| SS3P2L-M3/84A | 200 V VRRM, 3 A IF(AV), SMA package, VF = 0.75 V @ 3 A, 25 °C | Lower current rating and higher VF increase conduction loss by ~40% at 4.5 A; no side-wettable flanks or AOI support | Use only in low-cost, non-automotive prototypes where AOI is not required and thermal budget permits higher loss |
Compared with V9N3202-M3/I, V9N2020-M3/I offers superior thermal headroom but sacrifices board density, while SS3P2L-M3/84A trades performance and manufacturability for cost - making V9N3202-M3/I the optimal balance of size, efficiency, and process compatibility for mid-power SMT designs.

FAQ
What is the maximum junction temperature rating for the V9N3202-M3/I?
The V9N3202-M3/I has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is validated per JEDEC standards and supported by its 2.9 °C/W junction-to-mount thermal resistance. Derating curves in the official Vishay datasheet (Doc #98582) confirm stable performance up to this limit when mounted on appropriate copper pads. Always verify thermal design using the V9N3202-M3/I's RθJA = 118 °C/W value for your specific PCB layout.
Is the V9N3202-M3/I suitable for automotive applications?
The V9N3202-M3/I itself is commercial-grade; however, its AEC-Q101-qualified variant - V9N3202HM3/I - is explicitly designed and tested for automotive use. Both share identical electrical and thermal specs, but only the HM3 suffix indicates qualification per AEC-Q101 stress tests including HTGB, HTRB, and temperature cycling. For automotive designs requiring PPAP documentation and lot-level traceability, specify V9N3202HM3/I - the V9N3202-M3/I remains appropriate for industrial or consumer applications where AEC-Q101 is not mandated.
How does the DFN33A package of the V9N3202-M3/I support automated optical inspection (AOI)?
The V9N3202-M3/I uses a DFN33A package with side-wettable flanks - meaning the vertical edges of all four anode terminals and the cathode pad are fully plated with matte tin and exposed for solder fillet formation. This allows AOI systems to image solder joint quality from the side, verifying wetting and coplanarity without X-ray. The feature complies with IPC-A-610 Class 2/3 requirements and eliminates manual visual inspection in high-volume manufacturing. No special stencil or reflow profile changes are needed beyond standard DFN guidelines.
What is the forward voltage of the V9N3202-M3/I at 9 A and 125 °C?
The V9N3202-M3/I exhibits a maximum forward voltage (VF) of 0.71 V at 9 A and 125 °C, per the Vishay datasheet (Doc #98582, Electrical Characteristics table). At the same condition, the typical VF is 0.67 V. This low voltage - significantly better than planar Schottky alternatives - directly reduces conduction losses and improves system efficiency, especially in thermally constrained applications like sealed enclosures or multi-layer boards with limited copper area. Always reference the V9N3202-M3/I's derating curve (Fig. 1) to confirm usable current at target ambient temperatures.
Can the V9N3202-M3/I replace a standard Schottky diode in an existing design?
Yes, the V9N3202-M3/I can serve as a direct upgrade to many standard Schottky diodes in DFN33A-compatible footprints, provided the 200 V VRRM and 9 A IF(AV) ratings meet system requirements. Its lower VF (0.60 V @ 4.5 A / 125 °C vs. typical 0.75–0.85 V) improves efficiency, and its four-anode layout allows flexible PCB routing. However, verify thermal interface - the V9N3202-M3/I's RθJA = 118 °C/W assumes a 20 mm × 20 mm 2-oz copper pad. If replacing a TO-220 or SMA part, ensure the new DFN33A layout provides equivalent or better heat spreading. Always validate with the V9N3202-M3/I's full datasheet before release.
