Product details
Overview
VS-3EAH02-M3/I from Vishay Semiconductors is an ultrafast silicon rectifier diode in a DFN3820A surface-mount package, rated for 200 V peak reverse voltage, 3 A average forward current, and 15 ns typical reverse recovery time. It delivers low forward voltage (0.73 V at 3 A, 150 °C), low leakage (≤50 μA at 150 °C), and supports high-frequency PFC and CRM snubber operation in compact power converters.
For engineers reviewing the VS-3EAH02-M3/I datasheet, VS-3EAH02-M3/I pinout, VS-3EAH02-M3/I application, or VS-3EAH02-M3/I equivalent, this page provides verified electrical parameters, thermal resistance (RthJM = 4.5–6 °C/W), wettable flank package geometry, and real-world use cases in DC/DC converters, LED lighting, and freewheeling circuits - all confirmed from Vishay's official documentation (Doc. #97084, Rev. 26-Jul-2023).
Technical Context
This FRED Pt® diode employs optimized carrier lifetime control to achieve ultrafast soft recovery with minimal stored charge (Qrr = 23 nC typ. at 25 °C) and low peak reverse recovery current (IRRM = 3.8 A). Its DFN3820A footprint enables high-density layout while maintaining thermal performance via direct die-to-mount conduction.
The device operates across –55 °C to +175 °C junction temperature range, supports 260 °C reflow per J-STD-020 MSL Level 1, and features matte tin-plated terminals compliant with JESD 201 Class 2 whisker testing - enabling reliable automated optical inspection without X-ray.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Peak Reverse Voltage) | 200 V - blocks up to 200 V in reverse bias without breakdown, suitable for 100 VAC input PFC stages. |
| IF(AV) | 3 A at TM = 160 °C - continuous forward current rating under thermally optimized mounting conditions. |
| VF @ 3 A, 150 °C | 0.73 V - reduces conduction loss to ~2.2 W per diode in high-current switching paths. |
| trr (typ.) | 15 ns - enables operation above 500 kHz with minimal switching loss and EMI generation. |
| Qrr (typ.) | 23 nC at 25 °C - limits tail current energy dissipation during turn-off in hard-switched topologies. |
| RthJM | 4.5–6 °C/W - defines thermal path efficiency from junction to PCB copper mount pad. |
| IFSM | 61 A - withstands short-duration surge currents (10 ms sine pulse), supporting robust inrush handling. |
Pinout & Package
Package: DFN3820A - 3.95 mm × 2.18 mm × 0.88 mm ultra-low-profile, dual-terminal surface-mount package with wettable flanks and cathode marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to lower-potential side of circuit; must be routed with low-inductance trace for fast switching. |
| Cathode (K) | Forward current exit / reverse blocking terminal | Marked by color band; ties to higher-potential node; serves as primary heat-sinking interface to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Wettable flanks | Enables 100% solder joint inspection using AOI - eliminates need for X-ray in production line QA. |
| Low profile (0.88 mm height) | Permits stacking with adjacent components in space-constrained modules such as LED drivers and telecom bricks. |
| FRED Pt® technology | Delivers soft reverse recovery with controlled dI/dt, reducing voltage overshoot and RFI in snubberless designs. |
| MSL Level 1 rating | Allows single-pass 260 °C reflow without baking, simplifying SMT assembly and reducing process cost. |
| Halogen-free & RoHS-compliant | Meets IPC-1752A material declaration requirements for environmentally regulated industrial and consumer end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EAH02HM3 | Same die, identical electrical specs, but packaged in DFN3820A with different reel packaging (H code = 7" reel, 3500 pcs). | No functional difference; differs only in base quantity and tape/reel diameter - not a design-level alternative. | Select VS-3EAH02-M3/I for high-volume production requiring 13" reels (14,000 pcs) and optimized logistics planning. |
| ON Semiconductor NRVB3200T3G | 200 V, 3 A Schottky rectifier with 0.52 V VF (lower conduction loss) but 125 °C max TJ, no soft recovery, and higher leakage (>100 μA at 125 °C). | Better for low-VF priority in <100 kHz apps; unsuitable for CRM snubbers due to lack of controlled recovery. | Choose NRVB3200T3G only if thermal margin allows lower TJ and soft recovery is not required; VS-3EAH02-M3/I remains preferred for high-frequency PFC. |
Compared with VS-3EAH02-M3/I, VS-3EAH02HM3 offers identical performance in a smaller reel format, while NRVB3200T3G trades soft recovery and 175 °C rating for lower VF - making VS-3EAH02-M3/I the optimal choice where high-temperature reliability and EMI-controlled switching are critical.

FAQ
What is the maximum junction temperature rating for the VS-3EAH02-M3/I?
The VS-3EAH02-M3/I has a maximum junction temperature (TJ) of +175 °C, validated per Vishay's absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial power supplies where heatsinking is limited. The device maintains specified electrical performance up to this limit, with derating applied beyond TM = 160 °C for IF(AV).
Does the VS-3EAH02-M3/I support automated optical inspection (AOI)?
Yes, the VS-3EAH02-M3/I features wettable flanks on its DFN3820A package, enabling full solder joint inspection using standard AOI systems without requiring X-ray. This capability is explicitly confirmed in Vishay's datasheet (Doc. #97084) and aligns with J-STD-020 MSL Level 1 reflow compatibility - streamlining manufacturing QA for high-volume SMT lines.
How does the reverse recovery time of VS-3EAH02-M3/I vary with temperature and dI/dt?
The VS-3EAH02-M3/I exhibits a typical trr of 15 ns at 25 °C and increases to 17 ns at 125 °C under identical test conditions (IF = 0.5 A, IR = 1 A, dI/dt = 500 A/μs). Per Figure 7 in the datasheet, trr decreases slightly with higher dI/dt - e.g., ~11 ns at 500 A/μs and 25 °C - enabling predictable timing behavior across operating conditions.
Is the VS-3EAH02-M3/I halogen-free and RoHS-compliant?
Yes, the "-M3" suffix in VS-3EAH02-M3/I denotes halogen-free construction, RoHS compliance, and lead (Pb)-free terminations - fully documented in Vishay's ordering information and material declarations (Doc. #99912). This meets EU Directive 2011/65/EU and IPC-1752A reporting requirements for environmentally regulated end products.
What is the thermal resistance from junction to mount (RthJM) for VS-3EAH02-M3/I?
The VS-3EAH02-M3/I has a junction-to-mount thermal resistance (RthJM) of 4.5–6 °C/W, measured per JEDEC 51-14 TDIM methodology. This value reflects the thermal path through the DFN3820A package bottom to the PCB copper mount pad and is critical for calculating allowable power dissipation under real board-mount conditions.
