Product details
Overview
VS-3EYH01HM3/H from Vishay Semiconductors is a hyperfast recovery silicon rectifier diode in SlimSMAW (DO-221AD) package, rated for 100 V peak repetitive reverse voltage, 3 A average forward current, and 16 ns typical reverse recovery time at 125 °C. It delivers low forward voltage drop (0.71 V at 3 A, 150 °C), low leakage (≤2 μA at rated VR), and operates up to 175 °C junction temperature - ideal for high-frequency freewheeling and snubber circuits in automotive PFC stages.
For engineers reviewing the VS-3EYH01HM3/H datasheet, VS-3EYH01HM3/H pinout, VS-3EYH01HM3/H application, or VS-3EYH01HM3/H equivalent, this page provides verified electrical parameters, thermal resistance data (RthJM = 12–15 °C/W), AEC-Q101 qualification status, and real-world design implications for high-efficiency DC/DC converters and industrial power supplies.
Technical Context
This device belongs to Vishay's FRED Pt® family of hyperfast rectifiers optimized for minimal reverse recovery charge (Qrr = 23 nC typ. at 25 °C) and low stored charge tail. Its 16 ns trr at 100 A/μs dIF/dt enables efficient operation in hard-switched topologies above 100 kHz.
The SlimSMAW (DO-221AD) package features low-profile geometry (max height 3.00 mm), matte tin-plated leads compliant with J-STD-002, and UL 94 V-0 molding compound - supporting automated SMT placement and high-density board layouts without thermal derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Rated) | 100 V peak repetitive reverse voltage - defines maximum blocking capability in flyback or boost converter output stage |
| IF(AV) | 3 A average forward current at TC = 137 °C - supports continuous conduction mode operation with standard heatsinking |
| VF @ 3 A, 150 °C | 0.71 V typical - reduces conduction loss by ~18% vs. standard fast recovery diodes at elevated temperature |
| trr (typ.) | 16 ns at IF = 1.0 A, dIF/dt = 100 A/μs, VR = 30 V, TJ = 25 °C - enables clean turn-off with minimal switching noise in 200–500 kHz SMPS |
| Qrr (typ.) | 23 nC at TJ = 25 °C - lowers EMI and MOSFET switching losses in synchronous rectification and active clamp circuits |
| TJ(max) | 175 °C - allows operation in under-hood automotive environments and sealed industrial enclosures without forced cooling |
| RthJM | 12–15 °C/W - enables direct mounting to copper pour or metal-core PCB for thermal management without discrete heatsink |
Pinout & Package
Package: SlimSMAW (DO-221AD), surface-mount, single-diode configuration with cathode band marking. Dimensions: 4.00 × 2.70 × 3.00 mm (L × W × H), low-profile profile optimized for space-constrained power stages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switch node (e.g., MOSFET drain) in freewheeling path; requires low-inductance trace routing |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; color band identifies polarity - critical for correct orientation during automated placement |
Key Features
| Feature | Design Value |

| Halogen-free, RoHS-compliant, Pb-free terminations | Meets global environmental compliance requirements including JEDEC J-STD-020 MSL Level 1 (260 °C peak) |
| Low VF + low Qrr synergy | Reduces total power loss (conduction + switching) by ≥25% vs. standard FRD in 300 kHz PFC designs |
| Ultra-low leakage (≤2 μA @ VR, 25 °C) | Minimizes standby power loss in always-on systems such as automotive infotainment power rails |
| Thermal resistance RthJM ≤15 °C/W | Supports >2.5 W dissipation on 1-in² 2-oz Cu pad - eliminates need for thermal vias in many industrial applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY12010HM3/H | Same SlimSMAW package, 100 V rating, but higher IF(AV) = 4 A and lower VF = 0.67 V @ 3 A, 150 °C | Better suited for higher-current PFC stages where thermal margin is constrained | Select when board layout allows same footprint but system demands >3 A sustained current or lower conduction loss |
| STTH3L06S | TO-277A package (larger), 600 V rating, trr = 35 ns, VF = 1.15 V @ 3 A | Designed for higher-voltage industrial motor drives, not automotive-grade | Choose only if 600 V blocking is required and AEC-Q101 qualification is not mandatory |
