Product details
Overview
ES2BA-13 from Diodes Incorporated is a 100 V, 2.0 A surface-mount super-fast rectifier diode in SMA package with 25 ns reverse recovery time, 0.92 V forward voltage at 2.0 A, and 50 A non-repetitive surge capability - used in high-frequency switch-mode power supplies and DC-DC converters.
For engineers reviewing the ES2BA-13 datasheet, ES2BA-13 pinout, ES2BA-13 application, or ES2BA-13 equivalent, key selection criteria include peak reverse voltage rating (100 V), fast recovery performance (25 ns), thermal resistance (20 °C/W), RoHS-compliant lead-free plating, and compatibility with automated SMT assembly.
Technical Context
This super-fast rectifier employs glass-passivated die construction to achieve low leakage and stable junction characteristics across -55 °C to +150 °C operating range. Its 25 ns reverse recovery time enables efficient operation in 100–500 kHz switching topologies without significant switching loss penalties.
The device supports 2.0 A average forward current at terminal temperature ≤110 °C, with derating required for capacitive loads (20% current reduction). Thermal resistance of 20 °C/W assumes mounting on 5.0 mm² copper pad, directly linking PCB layout to thermal performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage; defines safe blocking capability in bridge or freewheeling configurations |
| IO | 2.0 A - average rectified output current at TT = 110 °C; sets continuous conduction limit in power stage design |
| trr | 25 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency operation with minimal switching loss |
| VFM | 0.92 V - forward voltage drop at IF = 2.0 A; determines conduction loss and thermal load under full load |
| RθJT | 20 °C/W - junction-to-terminal thermal resistance with 5.0 mm² copper pad; critical for estimating junction temperature rise |
| IFSM | 50 A - non-repetitive peak surge current (8.3 ms half-sine); supports inrush and fault-current handling |
| Cj | 25 pF - typical junction capacitance at 4.0 V reverse bias, 1 MHz; impacts high-frequency noise and EMI behavior |
Pinout & Package
SMA package: molded plastic case, UL 94V-0 rated, cathode indicated by band or notch; terminals are solder-plated and MIL-STD-202 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side in rectification path; must handle full load current and surge |
| Cathode | Forward current exit / reverse blocking node | Marked with band/notch; connects to output/load side; sustains up to 100 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enhances long-term reliability and moisture resistance in humid or thermally cycled environments |
| Super-fast recovery (25 ns) | Reduces switching losses in high-frequency SMPS designs compared to standard fast rectifiers (>50 ns) |
| Low VF (0.92 V @ 2.0 A) | Lowers conduction loss and improves efficiency in compact, thermally constrained power supplies |
| Lead-free / RoHS-compliant finish | Meets global environmental compliance requirements without requiring process requalification |
| JEDEC-standard SMA package | Ensures compatibility with standard SMT pick-and-place equipment and reflow profiles |
Applications
| AC-DC Adapter Power Supply | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Secondary-side rectification in 12–24 V output flyback adapters delivering up to 48 W. IC Role / Device Role / Timing Role: Super-fast rectifier replacing standard FR/UF diodes to reduce switching loss and improve efficiency. Use Value: 25 ns trr minimizes reverse recovery charge, lowering EMI and improving light-load regulation. | Use Scenario: Synchronous rectification alternative in isolated 5 V/3 A buck-derived converter for industrial IoT nodes. IC Role / Device Role / Timing Role: Freewheeling diode in non-synchronous secondary-side topology where MOSFET gate drive complexity is avoided. Use Value: 0.92 V VF limits conduction loss to <1.8 W at full load, easing thermal management on small PCBs. |
| Automotive LED Driver | Industrial Motor Control Snubber |
Use Scenario: Input rectification in 12 V automotive LED headlamp drivers with PWM dimming and EMC filtering. IC Role / Device Role / Timing Role: Bridge input rectifier handling cold-crank transients and load-dump surges. Use Value: 50 A IFSM withstands 12 V system transients without failure; 100 V VRRM provides margin above 16 V nominal. | Use Scenario: Snubber diode across IGBT gate driver outputs in 24 V BLDC motor control modules. IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback during fast gate switching transitions. Use Value: 25 ns trr ensures rapid turn-off, preventing latch-up or false triggering in high-dV/dt environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600 V VRRM, 2.0 A IO, 35 ns trr, TO-220AC package | Higher voltage rating but slower recovery and through-hole mounting | Select when >200 V blocking is required and board space allows larger footprint |
| MBR2100CT | 100 V VRRM, dual common-cathode Schottky, 2 × 1.0 A, 0.75 V VF, SMB package | Lower VF but higher leakage and limited to <125 °C junction temp | Prefer for ultra-low-loss 12 V systems where thermal margin permits Schottky limitations |
Compared with STTH2R06 and MBR2100CT, ES2BA-13 delivers optimal balance of speed (25 ns), thermal robustness (+150 °C), and SMT scalability in space-constrained 100 V rectification - without trade-offs in surge rating or RoHS compliance.

FAQ
What is the maximum junction temperature for ES2BA-13?
The ES2BA-13 has an operating junction temperature range of -55 °C to +150 °C. This rating is validated per JEDEC standards and applies under specified thermal conditions - including mounting on a 5.0 mm² copper pad. Exceeding +150 °C risks permanent degradation of the glass-passivated junction.
Is ES2BA-13 compatible with lead-free reflow processes?
Yes - ES2BA-13 features matte tin lead-free plating and is qualified for standard Pb-free reflow profiles (J-STD-020C Level 1). Its 260 °C peak reflow tolerance and UL 94V-0 mold compound ensure reliability in modern SMT assembly without post-process contamination concerns.
How does the 25 ns reverse recovery time impact EMI in a 250 kHz flyback design?
At 250 kHz, the 25 ns trr limits reverse recovery charge (Qrr) to ~12 nC (calculated from trr × di/dt), reducing high-frequency ringing amplitude and spectral energy above 30 MHz. This directly lowers conducted EMI in Class B power supplies without requiring additional snubbers.
Can ES2BA-13 replace ES2B-13 in the same PCB footprint?
No - ES2BA-13 uses the SMA package (smaller, 2.29–2.92 mm A-dimension), while ES2B-13 uses SMB (larger, 3.30–3.94 mm A-dimension). Their footprints are not interchangeable; redesign of pad layout and stencil is required to migrate between them.
