Product details
Overview
S3DB-13 from Diodes Incorporated is a 200 V peak repetitive reverse voltage, 3.0 A average rectified output current, glass passivated surface-mount silicon rectifier in SMB package, optimized for high-efficiency AC/DC front-end conversion in compact power supplies and LED drivers.
For engineers reviewing the S3DB-13 datasheet, S3DB-13 pinout, S3DB-13 application, or S3DB-13 equivalent, key selection criteria include its 1.15 V forward voltage at 3.0 A, 100 A non-repetitive surge rating, 10 µA reverse leakage at 25°C, thermal resistance of 10 °C/W, and RoHS-compliant lead-free plating.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads, with derating required for capacitive loads (−20% current). Its glass passivated die construction ensures stable junction behavior across −65°C to +150°C operating range.
The SMB package enables automated placement and reflow soldering, while the cathode band polarity marking and type-number/date-code laser marking comply with JEDEC and IPC standards for traceability and assembly verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the diode blocks without breakdown; sets minimum insulation margin in 115/230 VAC input stages. |
| IO @ TT=75°C | 3.0 A - Continuous DC output current capability when terminal temperature is held at 75°C; defines heatsink sizing baseline. |
| VFM @ IF=3.0A | 1.15 V - Forward voltage drop at rated current; determines conduction loss (3.45 W) and thermal load in linear operation. |
| IFSM (8.3 ms) | 100 A - Surge withstand capability for single half-sine waveform; supports inrush current handling in offline SMPS inputs. |
| IRM @ 25°C | 10 µA - Reverse leakage at rated DC blocking voltage; critical for low-power standby efficiency and isolation integrity. |
| RJT | 10 °C/W - Junction-to-terminal thermal resistance with 5.0 mm² copper pad; enables direct PCB thermal design without external heatsink. |
Pinout & Package
SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 rated, cathode band marked on body, solderable matte tin terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input node | Connects to transformer secondary or bridge input; carries full load current during positive half-cycle. |
| Cathode | DC output node | Delivers rectified unidirectional current to filter capacitor; marked by visible band for polarity verification. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates moisture-induced leakage drift and improves long-term reliability in humid environments. |
| Low VF (1.15 V @ 3 A) | Reduces conduction loss by ~15% vs. standard 1N54xx series, improving efficiency in 5–24 V output adapters. |
| 100 A IFSM rating | Withstands cold-start surges in universal-input AC/DC converters without degradation or failure. |
| RoHS-compliant matte tin finish | Enables lead-free reflow processing per J-STD-020C Level 1, eliminating post-solder cleaning steps. |
Applications
| LED Driver Power Supply | Industrial Sensor Power Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3.0 A IO, TO-277 package (smaller footprint than SMB but no cathode band marking) | Higher voltage rating suits 230 VAC-only systems; lacks 100 A IFSM surge rating | Select when higher reverse margin is needed and surge immunity is secondary. |
| ON Semi MUR320 | 200 V VRRM, 3.0 A IO, SMA package (0.5 mm taller, 0.2 mm wider than SMB), VF = 1.25 V @ 3 A | Same voltage/current specs but higher VF increases conduction loss by 0.3 W at full load | Choose only if existing SMA footprint compatibility is mandatory and 0.1 V VF penalty is acceptable. |
Compared with STTH3L06S and MUR320, S3DB-13 delivers superior surge robustness (100 A vs. 60 A/75 A), lower forward loss (1.15 V vs. 1.25 V), and standardized SMB polarity marking-making it optimal for high-volume, thermally constrained, and assembly-verified designs.

FAQ
What is the maximum allowable junction temperature for S3DB-13?
The absolute maximum junction temperature is +150°C, consistent with its specified operating temperature range of −65°C to +150°C. Derating begins at 75°C terminal temperature per the forward current derating curve, requiring thermal design to maintain TJ ≤ 150°C under worst-case ambient and power dissipation conditions.
Can S3DB-13 be used in full-wave bridge configurations?
Yes - S3DB-13 is a single diode and can be used in discrete full-wave bridge assemblies. Four units configured as a bridge deliver 3.0 A average output current with 200 V PIV per leg. However, integrated bridge packages (e.g., DB107) offer smaller footprint and matched characteristics for such applications.
Is the S3DB-13 marking "S3DB" followed by date code?
Yes - per DS16005 Rev. 10, the device is laser-marked with "S3DB" as the type number and a YWW date code (e.g., "248" = 2022, week 48). The cathode band serves as the sole polarity indicator; no additional symbols or logos are present on the SMB body.
Does S3DB-13 require derating for capacitive loads?
Yes - the datasheet explicitly states that average rectified current must be derated by 20% when used with capacitive loads. This accounts for increased peak current stress during capacitor charging transients, which elevates junction temperature beyond resistive/inductive load assumptions.
