Product details
Overview
V8N3170-M3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in DFN33A package, rated for 170 V reverse voltage and 8 A average forward current at infinite heatsink, with low 0.62 V forward voltage at 4 A and 125 °C junction temperature, used in DC/DC converters and polarity protection circuits.
For engineers reviewing the V8N3170-M3/I datasheet, V8N3170-M3/I pinout, V8N3170-M3/I application, or V8N3170-M3/I equivalent, key selection criteria include its AEC-Q101-qualified variant availability, side-wettable flanks for AOI, MSL Level 1 rating, 175 °C max junction temperature, and thermal resistance of 3.2 °C/W junction-to-mount.
Technical Context
This TMBS® rectifier uses trench MOS barrier technology to achieve lower forward voltage and higher efficiency than planar Schottky diodes. Its single-anode/cathode configuration supports unidirectional conduction in high-frequency switching topologies.
The DFN33A package features four anode terminals (pins 1–4) and one cathode (pin K), enabling parallel current paths and reduced thermal resistance. It meets JESD201 Class 2 whisker testing and JEDEC 51-14 transient dual-interface thermal measurement standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V8N170-M3/I | 170 V VRRM, 8 A IF(AV), same DFN33A package but standard TMBS® (not trench-enhanced); VF = 0.72 V @ 4 A/125 °C | Higher conduction loss; less suited for thermally constrained high-efficiency designs | Select when cost sensitivity outweighs 100 mV VF advantage and thermal margin is ample |
| SS8P17-M3/86A | 170 V VRRM, 8 A IF(AV), SMA package; VF = 0.79 V @ 4 A/125 °C; RθJA ≈ 40 °C/W (vs. 118 °C/W for V8N3170-M3/I) | Larger footprint, no side-wettable flanks, unsuitable for AOI; limited to lower-power or legacy layouts | Select only for through-hole or legacy SMT assembly where DFN33A rework or AOI capability is unavailable |
Compared with V8N170-M3/I and SS8P17-M3/86A, the V8N3170-M3/I delivers superior thermal performance (RθJM = 3.2 °C/W), lower VF, and AOI-ready packaging-making it optimal for high-density, high-reliability DC/DC and automotive power modules.

FAQ
What is the maximum junction temperature rating for the V8N3170-M3/I?
The V8N3170-M3/I has a maximum junction temperature (TJ max) of +175 °C, enabling operation in demanding thermal environments such as under-hood automotive electronics or enclosed industrial power supplies. This rating is validated per JEDEC standards and supported by its DFN33A package's low RθJM of 3.2 °C/W. The V8N3170-M3/I must be mounted on appropriate copper area to maintain safe TJ under full load.
Does the V8N3170-M3/I have AEC-Q101 qualification?
The V8N3170-M3/I itself is the commercial-grade version; however, the AEC-Q101 qualified variant is V8N3170HM3/I - identical in electrical and thermal specs but with additional stress testing per AEC-Q101 Rev D. Both share the same DFN33A package, marking code "V817", and halogen-free RoHS compliance. For automotive applications, specify V8N3170HM3/I explicitly.
What does the "M3" suffix mean in V8N3170-M3/I?
The "M3" suffix in V8N3170-M3/I indicates halogen-free, RoHS-compliant construction with matte tin-plated terminals that meet JESD201 Class 2 whisker resistance and J-STD-002 solderability requirements. It also denotes commercial-grade qualification (non-AEC-Q101). The "/I" denotes 13-inch tape-and-reel packaging with 6000 units per reel.
How many anode terminals does the V8N3170-M3/I have, and why?
The V8N3170-M3/I has four separate anode terminals (pins 1–4) and one shared cathode (K), as defined in the DFN33A mechanical drawing. This multi-anode layout reduces effective series resistance and distributes current and heat across multiple bond wires and PCB traces, improving current handling and thermal dissipation compared to single-anode Schottky devices.
Is the V8N3170-M3/I suitable for automatic optical inspection (AOI)?
Yes - the V8N3170-M3/I uses a DFN33A package with side-wettable flanks, allowing solder fillet inspection using standard AOI systems without requiring X-ray. This feature is confirmed in the Vishay datasheet (Doc #98550) and supports high-yield, low-cost SMT assembly in volume production environments.
