Product details
Overview
S2DA-13-F from Diodes Incorporated is a surface-mount, glass-passivated silicon rectifier diode in SMB package, rated for 200 V peak repetitive reverse voltage (VRRM), 1.5 A average forward current (I(AV)), and 50 A non-repetitive surge current (IFSM); used as primary AC/DC input rectifier in offline power supplies for consumer adapters and industrial SMPS.
For engineers reviewing the S2DA-13-F datasheet, S2DA-13-F pinout, S2DA-13-F application, or S2DA-13-F equivalent, key selection criteria include VRRM derating at elevated temperature, forward voltage drop at 1.5 A load, thermal resistance to PCB copper pad, surge robustness under line transients, and RoHS/Green compliance for production release.
Technical Context
This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60 Hz, with mandatory 20% current derating for capacitive-input filter configurations. Its glass-passivated junction ensures stable leakage performance up to 125°C junction temperature.
The SMB package provides 0.093 g mass and UL 94V-0 flammability rating, mounted on 5.0 mm² copper pads for RθJT = 20°C/W thermal resistance. Cathode polarity is marked by a band on the top surface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum reverse voltage before breakdown; sets minimum input stage insulation margin for 120/230 VAC designs. |
| I(AV) | 1.5 A @ TT = 100°C - Continuous DC output current capability when terminal temperature is held at 100°C via PCB heatsinking. |
| IFSM | 50 A (8.3 ms half-sine) - Withstands cold-start inrush into bulk capacitor without failure; critical for adapter reliability. |
| VFM | 1.15 V @ IF = 1.5 A - Forward conduction loss directly impacts efficiency and thermal design of low-voltage secondary-side rectification. |
| IRM | 5.0 µA @ 25°C / 125 µA @ 125°C - Low leakage preserves no-load input power and enables high-impedance hold-up circuits. |
| RθJT | 20°C/W - Thermal resistance from junction to terminal; defines required PCB copper area for thermal management per JEDEC JESD51-7. |
Pinout & Package
SMB (Surface Mount Body) package: molded plastic case, UL 94V-0 rated, cathode band marking, matte tin-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input node | Connected to transformer secondary or bridge input; carries full AC waveform during positive half-cycle. |
| Cathode | DC output node | Feeds bulk capacitor or downstream converter; polarity must match output rail orientation. |
Key Features
| Feature | Design Value |
|---|---|

| Surge rating: 50 A IFSM | Supports repeated cold-start events into 100 µF–470 µF bulk capacitors without parametric shift or failure. |
| Lead-free / RoHS compliant finish | Meets EU Directive 2002/95/EC exemptions; compatible with Pb-free reflow profiles (J-STD-020 Class 1). |
| Green molding compound (halogen-free) | Complies with IEC 61249-2-21; eliminates brominated flame retardants for safer end-of-life processing. |
Applications
| AC-DC Wall Adapters | Industrial SMPS Inputs |
|---|---|

Use Value: IRM ≤ 5 µA at 25°C ensures < 10 mW no-load input power, meeting Energy Star Tier 2 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB220-E3/54 (Vishay) | VRRM = 200 V, I(AV) = 2.0 A, VF = 0.95 V @ 2 A, SMB package | Higher current rating and lower VF enable higher efficiency at >1.5 A loads but requires revised thermal layout. | Select when designing for 2 A continuous output or tighter thermal constraints. |
| 1N4007G (ON Semiconductor) | VRRM = 1000 V, I(AV) = 1.0 A, VF = 1.1 V @ 1 A, DO-41 through-hole | Higher voltage rating suits legacy 230 VAC-only designs; through-hole mounting limits automated assembly throughput. | Select only for repair/refurbishment of existing through-hole boards where VRRM > 600 V is mandated. |
Compared with SB220-E3/54, S2DA-13-F offers tighter VF consistency across production lots and superior surge margin relative to its 1.5 A rating; compared with 1N4007G, it enables higher-density SMT layouts and meets modern green compliance mandates without redesigning the PCB.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The S2DA-13-F has an operating temperature range of –65°C to +150°C. For reliable long-term operation, junction temperature must be maintained ≤150°C. Derating curves in DS16004 show I(AV) drops to 1.0 A at TJ = 125°C and 0.5 A at TJ = 150°C under standard PCB mounting conditions.
Can S2DA-13-F replace S2AA-13-F in the same PCB footprint?
No - S2DA-13-F uses the SMB package (3.30–3.94 mm × 4.06–4.57 mm), while S2AA-13-F uses SMA (2.29–2.92 mm × 4.00–4.60 mm). Pad layout, thermal pad area, and mechanical clearance differ; direct substitution requires PCB revision and requalification.
Is the 50 A IFSM rating tested per JEDEC standards?
Yes - the 50 A non-repetitive peak forward surge current is specified for an 8.3 ms single half-sine wave per JEDEC JESD201, measured under defined thermal preconditioning and waveform conditions documented in DS16004 Rev. 14-2.
Does the "-F" suffix indicate halogen-free material?
Yes - the "-F" suffix denotes Diodes Incorporated's Green compound formulation: halogen-free (no bromine/chlorine), antimony-free, and compliant with IEC 61249-2-21; confirmed in Note 2 of DS16004 and supported by material declarations.
