Product details
Overview
VS-2EAH02-M3/I from Vishay Semiconductors is an ultrafast silicon rectifier diode in a DFN3820A surface-mount package, rated for 2 A average forward current and 200 V peak repetitive reverse voltage, with 15 ns typical reverse recovery time and 0.71 V forward voltage at 2 A and 150 °C - used as a freewheeling or snubber diode in high-frequency DC/DC converters.
For engineers reviewing the VS-2EAH02-M3/I datasheet, VS-2EAH02-M3/I pinout, VS-2EAH02-M3/I application, or VS-2EAH02-M3/I equivalent, key selection criteria include its low-profile DFN3820A footprint (0.88 mm height), wettable flanks for AOI inspection, 175 °C max junction temperature, and FRED Pt® process enabling fast soft recovery with low Qrr and low leakage.
Technical Context
This device is a single-anode/cathode ultrafast recovery diode fabricated using Vishay's FRED Pt® (Fast Recovery Epitaxial Diode, Platinum-doped) process, delivering soft reverse recovery with controlled dIF/dt dependence. Its dynamic behavior is characterized by trr = 15 ns (typ.) at 25 °C and 10 ns (typ.) at 125 °C under IF = 2 A, dIF/dt = 500 A/μs, VR = 200 V conditions.
The DFN3820A thermally enhanced package provides RthJM = 5–6.3 °C/W (junction-to-mount), enabling high-power-density mounting on copper pads. It meets J-STD-020 MSL Level 1 and JEDEC 51-14 TDIM thermal test standards, with matte tin-plated terminals compliant to JESD 201 Class 2 whisker testing.

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-2EYH02-M3/I | Same DFN3820A package, identical 200 V rating, but 35 ns trr (typ.) - slower recovery due to different doping profile | Higher Qrr (45 nC) and harder recovery increase EMI and MOSFET stress in high-frequency snubbers | Select only when cost sensitivity outweighs switching performance; not recommended for >300 kHz designs |
| ON Semiconductor NRVB20200CTT4G | TO-220AB package, dual common-cathode configuration, 200 V, 20 A total - larger footprint, higher thermal mass, no wettable flanks | Requires through-hole assembly and heatsinking; unsuitable for AOI-based SMT lines or thin-profile modules | Use only for legacy through-hole designs or high-current parallel configurations where DFN thermal limits are exceeded |
Compared with VS-2EAH02-M3/I, VS-2EYH02-M3/I trades speed for lower cost in less demanding topologies, while NRVB20200CTT4G offers higher current capacity at the expense of size, assembly compatibility, and high-frequency performance - making VS-2EAH02-M3/I optimal for modern SMT, high-efficiency, space-constrained power stages.

FAQ
What is the maximum junction temperature rating for the VS-2EAH02-M3/I?
The VS-2EAH02-M3/I has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in high-ambient environments such as enclosed LED drivers or industrial inverters. This rating is validated per JEDEC standards and supported by the DFN3820A package's low RthJM of 5–6.3 °C/W, allowing efficient heat transfer to the PCB mount pad without external heatsinking.
Does the VS-2EAH02-M3/I support automated optical inspection (AOI)?
Yes, the VS-2EAH02-M3/I features wettable flanks on its DFN3820A package, enabling full side-terminal visibility for automated optical inspection without requiring X-ray. This design eliminates solder joint voiding concerns in high-volume SMT lines and complies with IPC-A-610 Class 2/3 requirements for consumer and industrial applications.
What is the reverse recovery time (trr) of the VS-2EAH02-M3/I under typical operating conditions?
The VS-2EAH02-M3/I exhibits a typical reverse recovery time (trr) of 15 ns at TJ = 25 °C and 15 ns at TJ = 125 °C, measured at IF = 2 A, dIF/dt = 500 A/μs, and VR = 200 V. This ultrafast soft recovery minimizes switching losses and voltage overshoot in high-frequency topologies like active clamp flyback and resonant LLC converters.
Is the VS-2EAH02-M3/I halogen-free and RoHS-compliant?
Yes, the VS-2EAH02-M3/I is halogen-free and fully RoHS-compliant, as indicated by the "-M3" suffix in its part number. It uses lead (Pb)-free terminations and conforms to Vishay's material compliance standard documented in www.vishay.com/doc?99912, meeting global environmental regulations for electronics manufacturing.
What is the thermal resistance from junction to mount (RthJM) for the VS-2EAH02-M3/I?
The VS-2EAH02-M3/I has a junction-to-mount thermal resistance (RthJM) of 5–6.3 °C/W, measured per JEDEC 51-14 TDIM methodology. This low value reflects the DFN3820A package's optimized copper paddle and thermal pad design, enabling effective heat dissipation directly into the PCB copper layer without additional thermal vias or heatsinks in most 2 A applications.
