Product details
Overview
S3J-13 from Diodes Incorporated is a 600 V peak repetitive reverse voltage, 3.0 A average rectified output current, glass passivated surface-mount silicon rectifier in SMB package, optimized for single-phase half-wave AC/DC conversion in power supplies and industrial controls.
For engineers reviewing the S3J-13 datasheet, S3J-13 pinout, S3J-13 application, or S3J-13 equivalent, key selection criteria include its 100 A non-repetitive surge rating, 1.15 V forward voltage at 3.0 A, 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 unidirectional power rectifier with cathode-band polarity marking and is rated for continuous operation from –65°C to +150°C junction temperature. Its glass passivated die construction ensures stable reverse characteristics and low forward voltage drop under full-rated DC load.
The S3J-13 is specified for resistive or inductive loads at 60 Hz; for capacitive loads, output current must be derated by 20%. Thermal performance relies on mounting to a 5.0 mm² copper pad per JEDEC-standard thermal resistance test condition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak reverse voltage the device blocks without breakdown |
| IO @ TT = 75°C | 3.0 A - Continuous average forward current capability with terminal temperature limited to 75°C |
| IFSM (8.3 ms) | 100 A - Surge withstand capacity for one half-sine AC cycle, critical for inrush protection |
| VFM @ IF = 3.0 A | 1.15 V - Forward conduction loss at rated DC output, directly impacts power stage efficiency |
| IRM @ 25°C | 10 µA - Reverse leakage current at rated blocking voltage, affects standby power in high-impedance circuits |
| RJT | 10 °C/W - Junction-to-terminal thermal resistance with 5.0 mm² copper pad, defines heatsinking requirement |
| Tj Range | –65°C to +150°C - Operating junction temperature range, supports industrial and automotive under-hood environments |
Pinout & Package
S3J-13 uses the SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 flammability rating, solder-plated terminals compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input node | Accepts alternating input; conducts during positive half-cycle when cathode is more positive |
| Cathode | DC output node | Delivers rectified unidirectional current; marked with band or notch for polarity identification |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives |
| Low VF (1.15 V @ 3 A) | Reduces conduction losses in 5–24 V DC power rails, improving thermal margin in compact layouts |
| 100 A IFSM rating | Supports robust startup behavior in transformer-coupled supplies without fuse coordination issues |
| RoHS-compliant matte tin plating | Enables lead-free reflow assembly without solder wetting defects or intermetallic growth concerns |
Applications
| AC-DC Adapter Power Supply | Industrial Motor Control Board |
|---|---|
Use Scenario: 120/230 VAC input rectification feeding bulk capacitor in wall-wart adapters. IC Role / Device Role / Timing Role: Primary-side silicon rectifier converting AC line to pulsating DC before filtering and regulation. Use Value: 600 V VRRM provides 2× safety margin over 230 VAC RMS input, minimizing risk of reverse breakdown during transients. | Use Scenario: Rectifying auxiliary AC control voltage (e.g., 24 VAC) for logic supply in PLC I/O modules. IC Role / Device Role / Timing Role: Half-wave rectifier delivering isolated low-power DC bias for optocouplers and gate drivers. Use Value: 3.0 A IO rating accommodates short-duration inrush from relay coils while maintaining thermal stability. |
| LED Driver Input Stage | Automotive HVAC Blower Module |
Use Scenario: Input rectification in constant-current LED drivers operating from 120 VAC mains. IC Role / Device Role / Timing Role: Front-end rectifier enabling high-efficiency flyback topology with minimal conduction loss. Use Value: 1.15 V VF reduces heat generation in sealed enclosures where forced airflow is unavailable. | Use Scenario: Converting alternator-derived 14 VAC ripple into regulated 5 V for HVAC microcontroller supply. IC Role / Device Role / Timing Role: Low-leakage rectifier ensuring stable bias during engine cranking when battery voltage dips below 9 V. Use Value: 10 µA IRM at 25°C prevents excessive quiescent drain in always-on vehicle subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR360 | Ultrafast recovery (trr = 50 ns vs. S3J-13's ~2 µs), higher VF (1.7 V @ 3 A) | Better suited for high-frequency switching supplies; less optimal for line-frequency rectification | Select when EMI reduction or reduced switching loss outweighs conduction loss penalty |
| Vishay VS-3EWH06-M3 | Same SMB package, identical 600 V VRRM and 3.0 A IO, but lower VF (1.05 V @ 3 A) and tighter IRM spec (5 µA @ 25°C) | Direct replacement where lower conduction loss or tighter leakage is required | Prefer for thermally constrained designs or battery-backed systems sensitive to standby leakage |
Compared with MUR360 and VS-3EWH06-M3, the S3J-13 offers balanced trade-offs: lower cost than ultrafast alternatives, better thermal resistance than many competitors, and proven reliability in legacy industrial power designs without demanding high-frequency requirements.

FAQ
What is the maximum allowable junction temperature for S3J-13?
The S3J-13 has a specified operating junction temperature range of –65°C to +150°C. This upper limit is absolute; exceeding it risks permanent degradation of the glass passivation layer and increased reverse leakage. Derating curves in the datasheet define safe current limits based on terminal temperature, not ambient.
Is S3J-13 compatible with lead-free reflow soldering processes?
Yes - S3J-13 features matte tin lead-free plating and is qualified for standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D Level 1). Its SMB package withstands peak temperatures up to 260°C for 10 seconds, and the device meets RoHS Directive 2011/65/EU with exemptions for high-temperature solder and glass.
Can S3J-13 be used in full-wave bridge configurations?
No - S3J-13 is a single anode-cathode diode intended for half-wave rectification. For full-wave bridge operation, four discrete units (e.g., S3J-13 ×4) may be assembled externally, but Diodes Incorporated does not specify or characterize this configuration. Dedicated bridge rectifiers like GBU6K offer optimized layout, thermal coupling, and tested performance.
How does capacitive loading affect S3J-13's current rating?
Capacitive loading increases peak forward current and causes higher di/dt stress, so the datasheet mandates a 20% derating of the 3.0 A average output current rating. For example, at full capacitance input, maximum continuous IO drops to 2.4 A to prevent thermal runaway and ensure reliable lifetime under worst-case ESR and inrush conditions.
