Product details
Overview
ES3A-13-F from Diodes Incorporated is a 3.0A surface-mount super-fast rectifier diode in SMC package, rated for 50V peak repetitive reverse voltage, 0.9V max forward voltage at 3.0A, and 25ns reverse recovery time-optimized for high-frequency switching power supplies, DC/DC converters, and freewheeling applications.
For engineers reviewing the ES3A-13-F datasheet, ES3A-13-F pinout, ES3A-13-F application, or ES3A-13-F equivalent, key selection criteria include its 100A non-repetitive surge rating, 10°C/W junction-to-terminal thermal resistance, RoHS-compliant lead-free plating, and AEC-Q101 readiness for automotive-grade reliability validation.
Technical Context
This super-fast rectifier uses glass-passivated die construction to achieve stable reverse characteristics and low leakage (10µA @ 25°C, 500µA @ 125°C) under rated blocking voltage. Its 25ns reverse recovery time is measured under standardized conditions (IF = 0.5A, IR = 1.0A, IRR = 0.25A), enabling efficient operation in 100–500kHz SMPS topologies.
The device operates across –55°C to +150°C with a 50°C/W junction-to-ambient thermal resistance when mounted on a 5.0 mm² copper pad. Its SMC package supports automated assembly and delivers 3.0A average rectified current at terminal temperature ≤100°C per derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage | 50 V - defines maximum allowable reverse bias before breakdown in repetitive AC/DC applications |
| Average Rectified Current | 3.0 A at TT = +100°C - continuous DC output capability with thermal management |
| Max Forward Voltage | 0.9 V @ IF = 3.0A - limits conduction loss and self-heating in high-current paths |
| Reverse Recovery Time | 25 ns - enables high-frequency switching with minimal switching loss and EMI |
| Surge Current Rating | 100 A (8.3ms half-sine) - withstands inrush and transient overloads without failure |
| Junction-to-Terminal Rθ | 10 °C/W - supports direct thermal coupling to PCB copper for effective heat extraction |
| Operating Temperature | –55°C to +150°C - qualified for under-hood automotive and industrial ambient environments |
Pinout & Package
ES3A-13-F is housed in an SMC (DO-214AB) surface-mount plastic package with cathode band polarity marking. The two-terminal device has no internal connections beyond anode and cathode; terminals are matte tin-plated for lead-free solderability per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connects to input/high-side node in rectification path; must handle full load current and surge |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by band; connects to output/low-side; sustains 50V reverse bias with <10µA leakage at 25°C |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable reverse leakage and long-term reliability under humidity and thermal cycling |
| Super-fast 25ns recovery | Reduces switching losses and improves efficiency in >100kHz DC/DC converters |
| 100A surge rating | Supports robust operation during cold-start, motor commutation, or inductive kick events |
| RoHS & Halogen-free | Complies with EU directives and automotive "Green" standards (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| AC-DC Adapter Input Stage | Automotive LED Driver Freewheel |
|---|---|
Use Scenario: Rectifying 50/60Hz or high-frequency AC from transformer secondary in compact wall adapters. IC Role / Device Role / Timing Role: Primary unidirectional power conversion element handling 3A continuous output. Use Value: Low 0.9V VF minimizes conduction loss; 50V VRRM safely covers rectified peaks up to 35V RMS. | Use Scenario: Freewheeling path for inductive current in 12V automotive LED headlamp drivers. IC Role / Device Role / Timing Role: Clamp inductive flyback energy during MOSFET turn-off in buck or boost regulators. Use Value: 25ns tRR prevents cross-conduction loss; 100A IFSM absorbs transient surges from lamp hot-swap events. |
| DC/DC Converter Output Rectifier | Industrial PLC Power Supply Input |
Use Scenario: Secondary-side rectification in isolated 200–500kHz flyback or forward converters. IC Role / Device Role / Timing Role: High-efficiency synchronous or quasi-synchronous rectifier replacement. Use Value: 10°C/W RθJT enables direct thermal transfer to PCB ground plane, sustaining 3A at 100°C terminal temp. | Use Scenario: Input bridge rectification in DIN-rail mounted 24V/48V industrial power supplies. IC Role / Device Role / Timing Role: Discrete high-current rectifier in multi-phase or single-phase front-end stages. Use Value: –55°C to +150°C operating range ensures reliability in unventilated control cabinets with ambient up to 70°C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3.0A IO, 50ns tRR, TO-277 package | Higher voltage rating but slower recovery; suited for 400V PFC stages, not 50V SMPS outputs | Select only if system requires >500V blocking; avoid where 25ns timing is critical |
| MBR340F-E3/45 | Schottky, 40V VRRM, 3.0A IO, 0.52V VF, SMB package | No reverse recovery; lower VF but limited to ≤40V systems and higher leakage at 125°C | Prefer for low-VF, low-noise 12–24V DC/DC; not suitable for 50V+ or high-temp reverse-bias hold |
Compared with STTH3L06S and MBR340F-E3/45, ES3A-13-F uniquely balances 50V rating, 25ns speed, and 3A current in SMC-making it optimal for cost-sensitive, thermally constrained 50V-class switchers where Schottky leakage or slow recovery would degrade efficiency or reliability.

FAQ
What is the maximum junction temperature for ES3A-13-F?
The absolute maximum junction temperature is +150°C, consistent with its specified operating and storage temperature range of –55°C to +150°C. Thermal design must ensure junction temperature remains within this limit using the 10°C/W junction-to-terminal and 50°C/W junction-to-ambient thermal resistances under defined PCB mounting conditions.
Is ES3A-13-F qualified for automotive use?
ES3A-13-F is built in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 out-of-box, Diodes offers AEC-Q101 qualification upon request for automotive programs-confirming robustness for under-hood and lighting applications.
How does the SMC package compare to SMB for ES3A-13-F?
ES3A-13-F uses the larger SMC (DO-214AB) package, offering higher thermal mass and 3.0A current rating at +100°C terminal temperature. The SMB variant (ES3AB-13-F) shares identical electrical specs but is rated for 2.0A average current due to lower thermal dissipation capacity.
Can ES3A-13-F replace a standard FR304 diode?
No-FR304 is a 400V, 3A fast recovery diode with ~500ns tRR. ES3A-13-F's 50V rating and 25ns tRR make it incompatible for 400V applications but superior in low-voltage, high-frequency circuits where faster recovery and lower VF reduce losses.
