Product details
Overview
S3K-13-F from Diodes Incorporated is a 3.0A, 800V peak repetitive reverse voltage (VRRM), glass passivated surface-mount rectifier in SMC package, featuring 1.15V forward voltage at 3.0A, 100A non-repetitive surge capability, and RoHS-compliant matte tin plating - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the S3K-13-F datasheet, S3K-13-F pinout, S3K-13-F application, or S3K-13-F equivalent, key selection criteria include VRRM rating, thermal resistance (RθJT = 10°C/W), forward voltage drop, surge robustness (IFSM = 100A), and SMC package compatibility with automated PCB assembly.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for high-current, medium-voltage DC output generation. Its glass passivated die construction ensures stable reverse leakage (IRM ≤ 250 µA at +125°C) and reliable junction-to-terminal thermal performance under sustained load.
The SMC package enables direct mounting on 5.0 mm² copper pads for effective heat dissipation, supporting continuous 3.0A average forward current at terminal temperature (TT) up to +75°C. Capacitance is low (CT = 40 pF @ 1 MHz), minimizing switching noise in high-frequency rectifier stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak reverse transients up to 800V without breakdown in AC line rectification. |
| IO (at TT = +75°C) | 3.0 A - Sustained average forward current rating under standard heatsinking conditions. |
| VFM @ IF = 3.0A | 1.15 V - Low conduction loss enabling >85% efficiency in 24–48V output power supplies. |
| IFSM (8.3ms) | 100 A - Handles inrush surges from bulk capacitors or motor startup without failure. |
| RθJT | 10 °C/W - Junction-to-terminal thermal resistance measured on 5.0 mm² copper pad; defines thermal design margin. |
| IRM @ +125°C | 250 µA - Confirmed reverse leakage at elevated temperature; critical for standby power budgeting. |
| CT @ 1 MHz | 40 pF - Low junction capacitance reduces EMI in high-frequency switching rectifier circuits. |
Pinout & Package
Package: SMC (Surface-Mount Case), molded plastic body per UL 94V-0, cathode identified by band marking. Dimensions: 6.60–7.11 mm (L) × 2.75–3.18 mm (W) × 2.00–2.50 mm (H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for AC or positive half-cycle | Connected to transformer secondary or bridge input; carries full load current during conduction. |
| Cathode | DC output node | Feeds bulk capacitor or downstream regulator; polarity marked by band on package top surface. |
Key Features
| Feature | Design Value |
|---|---|

| 100A surge rating (8.3ms) | Survives cold-start inrush into large electrolytic banks without parametric shift or failure. |
| Low RθJT (10°C/W) | Enables compact thermal design without external heatsinks in 3A-class industrial SMPS. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Front-End Rectification |
|---|---|
Use Scenario: Rectifying 100–277VAC mains input in enclosed 30–60W industrial power supplies. IC Role / Device Role / Timing Role: Primary unidirectional current path converting AC to pulsating DC before bulk filtering. Use Value: 800V VRRM prevents breakdown during line surges; 1.15V VFM limits conduction loss to <3.5W at full load. |
Use Scenario: Off-line rectification feeding constant-current LED driver ICs in streetlight modules. IC Role / Device Role / Timing Role: High-reliability diode in bridge or single-diode configuration handling 3A steady-state current. Use Value: Glass passivation ensures stability across -40°C to +85°C ambient; 100A IFSM tolerates lamp hot-restrike events. |
| Automated Assembly-Compatible SMPS | Capacitor-Input Filter Stages |
Use Scenario: High-volume production of DIN-rail mounted 24V/3A power modules using pick-and-place assembly. IC Role / Device Role / Timing Role: Surface-mount rectifier placed directly onto PCB with no through-hole holes or manual soldering. Use Value: SMC package footprint and matte tin terminations ensure >99.8% first-pass solder yield in nitrogen reflow profiles. |
Use Scenario: Bulk capacitor charging stage where peak current exceeds average current by >3× (e.g., 12V/5A outputs). IC Role / Device Role / Timing Role: Conducts short-duration high-current pulses while blocking reverse voltage between cycles. Use Value: Derated 20% current limit for capacitive loads is explicitly defined; validated via Fig. 1 derating curve. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, TO-277 package, RθJT = 12°C/W, VFM = 1.1V @ 3A | Limited to lower line-voltage designs (≤277VAC); higher thermal resistance requires larger copper area | Select when 600V rating suffices and TO-277 mechanical retention is preferred over SMC tape-and-reel automation. |
| MBR360T3G | Schottky, 60V VRRM, SMC package, VFM = 0.62V @ 3A, no reverse recovery | Not suitable for 800V line applications; only usable in low-voltage DC-DC or OR-ing | Choose only for <100V DC systems requiring zero Qrr and ultra-low VFM; not a functional substitute for S3K-13-F. |
Compared with STTH3L06S and MBR360T3G, S3K-13-F uniquely balances 800V ruggedness, SMC manufacturability, and 3A thermal capability - making it irreplaceable in universal-input industrial power supplies where both voltage margin and assembly scalability are mandatory.

FAQ
What is the maximum allowable junction temperature for S3K-13-F?
The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent parametric shift or catastrophic failure. Derating curves (Fig. 1) define safe current limits based on terminal temperature, not ambient - proper copper pad sizing is essential to maintain TJ ≤ 150°C at full load.
Is S3K-13-F suitable for use in a full-wave bridge configuration?
Yes - S3K-13-F is a single diode rated for full-wave bridge use when paired with three identical units. Its 800V VRRM supports 400V RMS input lines, and its 100A IFSM withstands bridge inrush currents. Ensure matched thermal layout across all four positions to avoid current imbalance and localized overheating.
Does S3K-13-F have a specified reverse recovery time (trr)?
No - as a standard PN junction rectifier, trr is not characterized or guaranteed in the datasheet. The device exhibits typical soft recovery behavior, but designers requiring fast or controlled recovery must select an explicitly rated ultrafast or soft-recovery diode (e.g., UF3007 or STTH3R06).
Can S3K-13-F be substituted with an SMB-package variant like S3KB-13-F?
Only if current derating is accepted: S3KB-13-F (SMB) shares identical electrical specs but has higher thermal resistance (RθJT ≈ 15°C/W vs. 10°C/W for SMC), limiting continuous current to ~2.2A at +75°C terminal temperature. Mechanical fit and board layout must also be verified - SMB and SMC footprints are not interchangeable.
