Product details
Overview
S3D-13 from Diodes Incorporated is a 200 V peak repetitive reverse voltage, 3.0 A average rectified surface-mount glass passivated silicon rectifier in SMB package, with 1.15 V forward voltage at 3.0 A, 100 A non-repetitive surge rating, and 10 µA reverse leakage at 25°C - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the S3D-13 datasheet, S3D-13 pinout, S3D-13 application, or S3D-13 equivalent, key selection criteria include VRRM = 200 V, IO = 3.0 A @ TT = 75°C, thermal resistance RJT = 10 °C/W, RoHS-compliant lead-free finish, and SMB package compatibility with automated SMT assembly.
Technical Context
This device is a single-phase, half-wave silicon rectifier diode optimized for high-current, low-loss operation in switching and line-frequency power conversion. Its glass passivated die construction ensures stable reverse characteristics across -65°C to +150°C operating range and supports reliable surge handling up to 100 A (8.3 ms half-sine).
The SMB package provides standardized mechanical dimensions (3.30–3.94 mm length × 4.06–4.57 mm width × 1.96–2.21 mm height), solderable terminals per MIL-STD-202 Method 208, and UL 94V-0 flammability rating - enabling direct integration into thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the diode blocks without breakdown; defines safe AC input voltage headroom in bridge or single-diode rectifiers. |
| IO | 3.0 A @ TT = 75°C - Continuous DC output current capability when mounted on 5.0 mm² copper pad; derated to ~2.4 A for capacitive loads. |
| VFM | 1.15 V @ IF = 3.0 A - Forward conduction loss at rated current; contributes directly to thermal dissipation (P ≈ 3.45 W at full load). |
| IFSM | 100 A - Peak surge current tolerance for one 8.3 ms half-sine cycle; enables robustness against line transients and inrush events. |
| IRM | 10 µA @ 25°C - Reverse leakage at rated DC blocking voltage; ensures minimal standby power loss in high-impedance bias networks. |
| RJT | 10 °C/W - Junction-to-terminal thermal resistance with specified PCB copper pad; determines temperature rise under steady-state power dissipation. |
Pinout & Package
SMB (Surface Mount Body) package: molded plastic case, UL 94V-0 rated, cathode marked by band or notch on body, solder-plated terminals compatible with reflow and wave soldering per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to AC source or transformer secondary; must handle full load current and surge peaks without trace overheating. |
| Cathode | Current exit terminal during forward conduction | Connected to bulk capacitor or downstream regulator; polarity marking (band/notch) prevents reverse installation in automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable reverse leakage and long-term reliability under thermal cycling and humidity exposure. |
| Low forward voltage drop | 1.15 V at 3.0 A reduces conduction losses and eases thermal management in compact power stages. |
| 100 A surge rating | Supports robust operation during cold-start inrush and AC line disturbances without degradation. |
| RoHS-compliant lead-free finish | Meets EU Directive Annex exemptions for glass and high-temp solder; suitable for global production compliance. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase rectification of 120/230 VAC mains feeding offline flyback or buck-derived LED drivers. IC Role / Device Role / Timing Role: Primary-side unidirectional current switch converting AC input to pulsating DC bus. Use Value: 200 V VRRM provides 1.4× safety margin over 120 VAC RMS; 3.0 A IO sustains typical 20–30 W LED loads with margin. | Use Scenario: Input stage rectification in constant-current LED drivers for street lighting and commercial fixtures. IC Role / Device Role / Timing Role: High-efficiency, low-loss rectifier in bridge or single-diode configuration feeding bulk storage capacitor. Use Value: 1.15 V VFM minimizes heat generation in sealed enclosures; SMB footprint enables dense PCB layout. |

Use Scenario: Mains-powered embedded controllers requiring isolated 5 V/12 V auxiliary rails via transformer-based SMPS. IC Role / Device Role / Timing Role: Input rectifier in transformer secondary-side full-wave or half-wave rectification circuit. Use Value: 10 µA IRM at 25°C prevents significant standby current drain; -65°C to +150°C rating supports wide ambient operation. | Use Scenario: Low-cost auxiliary power supply for gate drivers and logic in brushed DC motor control modules. IC Role / Device Role / Timing Role: Half-wave rectifier generating unregulated DC rail for local LDO or linear regulator input. Use Value: 100 A IFSM withstands motor stall-induced line surges; SMB package allows direct mounting near motor driver ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR320SFT1G | Ultrafast recovery (trr = 50 ns vs. S3D-13's ~2 µs), same VRRM/IO, SMC package | Better suited for high-frequency PFC or flyback snubber circuits where reverse recovery loss matters | Select when operating >20 kHz or minimizing EMI from reverse recovery ringing |
| Vishay VS-3EWH02-M3/5AT | Same SMB package, 200 V VRRM, but lower IO = 2.0 A and higher VFM = 1.25 V | Acceptable for lower-power (<15 W) or thermally relaxed designs with reduced current demand | Choose only if board space is identical and thermal margin exceeds 25°C above junction limit |
Compared with MUR320SFT1G and VS-3EWH02-M3/5AT, the S3D-13 offers optimal balance of surge robustness, thermal resistance, and cost for line-frequency rectification - making it preferred for industrial and LED driver applications where ultrafast recovery is unnecessary.

FAQ
What is the maximum allowable junction temperature for S3D-13?
The S3D-13 has an absolute maximum junction temperature of +150°C, with continuous operation limited by thermal design to maintain Tj ≤ 150°C. At 3.0 A IO and 75°C terminal temperature, junction rise is ~30°C (RJT × Pdiss), assuming 1.15 V forward drop and no additional ambient rise beyond the specified TT condition.
Is S3D-13 suitable for use in a full-wave bridge configuration?
Yes - S3D-13 is a single diode intended for use in discrete full-wave bridge assemblies. Four S3D-13 units can form a 200 V, 3.0 A bridge; however, its 2 µs reverse recovery time makes it unsuitable for high-frequency (>10 kHz) bridge operation where fast recovery diodes are required to minimize switching loss.
Does S3D-13 have a lead-free and RoHS-compliant version?
Yes - the standard S3D-13 is RoHS-compliant per EU Directive Annex Notes 5 and 7, with glass and high-temperature solder exemptions applied. It features matte tin lead-free plating and meets J-STD-020C moisture sensitivity Level 1, verified by Diodes Incorporated's DS16005 Rev. 10 documentation.
How does the SMB package of S3D-13 compare thermally to the SMC variant (S3D-13)?
The SMB package (S3D-13) has higher thermal resistance (RJT = 10 °C/W) than the SMC variant (S3D-13, RJT ≈ 6.5 °C/W), due to smaller copper pad area and lower mass. For identical 3.0 A loads, SMB will run ~35°C hotter at the junction - requiring larger PCB copper areas or forced airflow in thermally demanding applications.
