Product details
Overview
S3D from Diodes Incorporated is a 200 V peak repetitive reverse voltage, 3.0 A average rectified output current, glass passivated surface-mount silicon rectifier diode in SMB/SMC package, optimized for high-efficiency AC/DC front-end rectification in power supplies and adapters.
For engineers reviewing the S3D datasheet, S3D pinout, S3D application, or S3D equivalent, key selection criteria include its 1.15 V forward voltage at 3.0 A, 100 A non-repetitive surge rating, 40 pF junction capacitance, thermal resistance of 10 °C/W, and RoHS-compliant matte tin plating for automated assembly reliability.
Technical Context
This device operates as a unidirectional power rectifier in single-phase, half-wave configurations with resistive or inductive loads. It supports full-wave bridge topologies when paired with complementary devices and requires derating by 20% under capacitive load conditions.
Thermal performance is defined with junction-to-terminal resistance of 10 °C/W when mounted on a 5.0 mm² copper pad. Reverse leakage remains ≤10 µA at 25°C and ≤250 µA at 125°C under rated DC blocking voltage, ensuring stable operation across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage before breakdown; defines safe operating limit in AC line rectification |
| IO @ TT=75°C | 3.0 A - Continuous DC output current capability with thermal management at terminal temperature |
| VFM @ IF=3.0A | 1.15 V - Forward conduction loss directly impacts efficiency and thermal rise in high-current paths |
| IFSM (8.3ms) | 100 A - Surge withstand capacity for inrush current protection without failure |
| RθJT | 10 °C/W - Junction-to-terminal thermal resistance measured on standard PCB copper pad heat sink |
| CT @ 1MHz | 40 pF - Junction capacitance affects high-frequency switching noise and EMI filtering design |
| TJ Range | −65 to +150 °C - Operating junction temperature range suitable for extended industrial environments |
Pinout & Package
Package: SMB (DO-214AA) or SMC (DO-214AB), molded plastic case with UL 94V-0 flammability rating; cathode identified by band or notch; matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point during forward conduction | Connected to AC source or transformer secondary; must handle full 3.0 A RMS and 100 A surge |
| Cathode | Output current exit point during forward conduction | Feeds bulk capacitor or downstream regulator; polarity marking critical for PCB layout verification |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Enhances moisture resistance and long-term reliability in humid or reflow-cycled environments |
| Lead-free, halogen-free "Green" finish | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity for zero bake requirement |
| 100 A surge rating (8.3 ms) | Withstands cold-start inrush in offline SMPS without degradation or parametric shift |
| Low 1.15 V VF at 3.0 A | Reduces conduction loss by ~15% vs. legacy 1.35 V diodes, lowering heatsink requirements |
| Standard SMB/SMC footprint | Enables drop-in replacement in existing designs using DO-214AA/AB land patterns |

Use Value: Stable IRM ≤10 µA at 25°C prevents standby power drain; glass passivation resists electrolyte vapor exposure near batteries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MURS320 | Ultrafast recovery (trr = 35 ns vs. S3D's ~2 µs); VF = 1.25 V @ 3.0 A | Better suited for high-frequency flyback or PFC stages where reverse recovery loss dominates | Select when switching frequency >100 kHz; avoid if cost-sensitive or low-noise line-frequency rectification required |
| Vishay VS-3EYH02-M3/54 | Same SMB package; VF = 1.1 V @ 3.0 A; VRRM = 200 V; trr = 1.5 µs | Near-identical electrical specs but tighter VF distribution and enhanced surge margin (120 A IFSM) | Drop-in alternative with improved consistency for high-volume production; verify date-code traceability per batch |
Compared with MURS320 and VS-3EYH02-M3/54, the S3D offers optimal balance of low VF, proven surge robustness, and cost-effective glass passivation-making it preferred for line-frequency rectification where ultrafast recovery is unnecessary.

FAQ
What is the maximum allowable junction temperature for continuous operation of the S3D?
The S3D has a specified operating junction temperature range of −65 °C to +150 °C. For continuous operation at rated 3.0 A average current, thermal design must ensure junction temperature stays within this limit-typically achieved using ≥5.0 mm² copper pad area and maintaining terminal temperature ≤75 °C per derating curve.
Can the S3D be used in full-wave bridge configurations?
Yes-the S3D is a single-diode rectifier intended for use in discrete full-wave bridge assemblies. Four S3D units can form a standard bridge rectifier. Its 200 V VRRM and 100 A IFSM make it suitable for 115 VAC input bridges; for 230 VAC, S3G (400 V) or higher variants are recommended.
Is the S3D compliant with lead-free and halogen-free requirements?
Yes-S3D carries a matte tin lead-free finish and meets RoHS 2 (2011/65/EU) compliance. It is also classified as "Green" per Diodes Incorporated's definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br+Cl), and <1000 ppm antimony compounds.
How does the S3D's forward voltage compare to Schottky alternatives at 3.0 A?
At 3.0 A, S3D exhibits VF = 1.15 V, whereas typical 200 V Schottky rectifiers (e.g., SB320) show VF ≈ 0.85–0.95 V. However, Schottkys have higher reverse leakage (>100 µA at 125 °C) and lower VRRM consistency-making S3D preferable where reverse leakage and thermal stability outweigh marginal VF advantage.
