Product details
Overview
ES2DA-13 from Diodes Incorporated is a 200 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 rating - used in high-frequency AC/DC converters and switch-mode power supplies.
For engineers reviewing the ES2DA-13 datasheet, ES2DA-13 pinout, ES2DA-13 application, or ES2DA-13 equivalent, key selection criteria include peak reverse voltage (200 V), fast recovery (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 forward voltage drop and high reliability under repetitive surge stress. Its 25 ns reverse recovery time enables efficient operation in 100–500 kHz switching topologies without excessive switching loss.
The device is rated for 2.0 A average forward current at terminal temperature of 110 °C, with thermal resistance of 20 °C/W when mounted on 5.0 mm² copper pad. It supports capacitive-load applications with 20% derating and withstands 50 A single half-sine surge per JEDEC method.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage; defines safe blocking capability in bridge or flyback configurations |
| IO | 2.0 A - average rectified output current at TT = 110 °C; sets continuous conduction limit in power supply outputs |
| trr | 25 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency switching with minimal turn-off loss |
| VFM | 0.92 V - forward voltage at IF = 2.0 A; directly determines conduction loss and thermal rise in rectification path |
| RθJT | 20 °C/W - junction-to-terminal thermal resistance with 5.0 mm² copper pad; critical for thermal design margin in compact layouts |
| IFSM | 50 A - non-repetitive peak forward surge current (8.3 ms half-sine); supports cold-start and line-transient robustness |
| Cj | 25 pF - typical junction capacitance at 4.0 V reverse bias, 1 MHz; impacts high-frequency noise and EMI filter interaction |
Pinout & Package
SMA package: molded plastic case (UL 94V-0), cathode band polarity marking, solderable matte tin-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must handle full surge current and thermal dissipation |
| Cathode | Forward current exit / reverse-blocking node | Connected to output capacitor or DC bus; marked by band/notch; carries full load current and reverse leakage |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | 200 V, 2.0 A, 22 ns trr, TO-277 package (higher RθJA) | Higher thermal resistance requires larger copper area; not tape-and-reel compatible with same footprint | Prefer when lower trr is critical and board layout allows TO-277 mounting |
| MBR220LSFT1G | 20 V, 2.0 A Schottky, 0.52 V VF, no reverse recovery | Only suitable for ≤20 V DC-DC outputs; cannot replace in 200 V AC/DC applications | Select only for low-voltage, ultra-low-loss freewheeling where reverse voltage <25 V |
Compared with STTH2R02DJF and MBR220LSFT1G, ES2DA-13 offers optimal balance of 200 V blocking, 25 ns speed, SMA footprint compatibility, and 50 A surge capability - making it uniquely suited for cost-sensitive, space-constrained AC/DC adapters requiring RoHS compliance and automated assembly.

FAQ
What is the maximum operating junction temperature for ES2DA-13?
The ES2DA-13 has an operating junction temperature range of –55 °C to +150 °C. Its thermal resistance is specified as 20 °C/W junction-to-terminal when mounted on a 5.0 mm² copper pad. Derating begins above 110 °C terminal temperature, where average forward current drops linearly to zero at 150 °C.
Is ES2DA-13 compatible with lead-free reflow processes?
Yes - ES2DA-13 features matte tin lead-free plating compliant with RoHS Directive 2002/95/EC (Annex exemptions applied). It is qualified for standard Pb-free reflow profiles up to 260 °C peak, with moisture sensitivity level 1 per J-STD-020C, eliminating bake requirements before assembly.
How does the 25 ns reverse recovery time impact EMI in switch-mode designs?
The 25 ns trr minimizes reverse recovery current tail and associated dI/dt-induced ringing, reducing high-frequency common-mode noise coupling into input filters and adjacent signal traces. Measured data shows >6 dB lower 30–100 MHz radiated emissions versus 50 ns rectifiers in identical 65 kHz flyback layouts.
Can ES2DA-13 replace ES2D-13 in existing designs?
Yes - ES2DA-13 (SMA) and ES2D-13 (SMB) share identical electrical specifications (200 V, 2.0 A, 25 ns), but differ in package size and thermal mass. SMA is smaller (2.29 × 4.00 mm) with lower weight (0.064 g); SMB offers slightly better thermal dissipation. Footprint redesign is required, but no circuit changes are needed.
