Product details
Overview
S2D-13 from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode rated for 200 V peak repetitive reverse voltage (VRRM), 1.5 A average forward current (I(AV)) at 100°C terminal temperature, and 50 A non-repetitive surge current (IFSM), used as a primary AC/DC input rectifier in low-power offline power supplies and adapter front-ends.
For engineers reviewing the S2D-13 datasheet, S2D-13 pinout, S2D-13 application, or S2D-13 equivalent, key selection criteria include its 1.15 V forward voltage at 1.5 A, 5 µA max reverse leakage at 25°C, 20 pF junction capacitance, 20 °C/W thermal resistance (junction-to-terminal), and SMA package compatibility with automated reflow assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz line-frequency conditions with resistive or inductive loads; capacitive loads require 20% current derating. Its glass passivated die construction ensures stable reverse characteristics and high reliability in thermally constrained PCB layouts.
The SMA package (A-suffix) provides defined thermal path via copper pad heatsinking (5.0 mm², 0.013 mm thick), enabling operation across –65°C to +150°C junction temperature range while maintaining 1.15 V VF and ≤5 µA IR at rated blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the diode blocks without breakdown; defines safe AC input voltage headroom (e.g., 120 VAC RMS × √2 ≈ 170 V peak). |
| I(AV) | 1.5 A @ TT = 100°C - Continuous DC output current capability when mounted on specified PCB copper area; sets minimum trace width and thermal pad design. |
| VFM | 1.15 V @ IF = 1.5 A - Forward conduction loss at rated load; determines power dissipation (1.725 W) and thermal management requirements. |
| IFSM | 50 A @ 8.3 ms - Surge withstand for cold-start inrush or line transients; enables robustness without external fusing in Class II adapters. |
| IRM | 5.0 µA @ 25°C, rated VR - Reverse leakage at room temperature; impacts standby power in no-load conditions. |
| RJT | 20 °C/W - Junction-to-terminal thermal resistance with defined PCB heatsink; used to calculate junction temperature rise (ΔTj = Pd × RJT). |
Pinout & Package
SMA package (DO-214AC): molded plastic case, UL 94V-0 rated, cathode indicated by band marking; terminals are anode (A) and cathode (K); designed for surface-mount reflow soldering with 0.064 g mass and standardized land pattern per JEDEC MS-013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | AC input / positive half-cycle entry point | Connected to transformer secondary or bridge input; must handle full surge current and RMS current without trace overheating. |
| Cathode (K) | DC output / rectified voltage source | Feeds bulk capacitor or downstream regulator; polarity marking critical for correct PCB orientation and ESD-safe handling. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates moisture-induced degradation and improves long-term reverse leakage stability vs. epoxy-passivated alternatives. |
| Low VF (1.15 V) | Reduces conduction loss by ~15% compared to standard 1N400x series at 1.5 A, improving efficiency in <10 W adapters. |
| 50 A IFSM rating | Supports direct connection to 120/230 VAC inputs without series NTC or inrush limiters in cost-sensitive designs. |
| RoHS-compliant lead-free finish | Meets EU Directive Annex Notes 5 & 7 exemptions for glass and high-temp solder; compatible with Pb-free reflow profiles (J-STD-020C Level 1). |
Applications
| AC-DC Wall Adapters | USB Power Delivery Front-Ends |
|---|---|
Use Scenario: 5–12 W universal-input (90–264 VAC) wall adapters powering IoT sensors and Bluetooth peripherals. IC Role / Device Role / Timing Role: Primary input rectifier converting AC line to pulsating DC before bulk capacitor and flyback controller. Use Value: 1.15 V VF minimizes heat generation in compact enclosures; 200 V VRRM supports 264 VAC input with 20% safety margin. | Use Scenario: USB-C PD 5 V/3 A or 9 V/2 A fixed-output adapters with minimal BOM count. IC Role / Device Role / Timing Role: Half-wave rectifier in simplified flyback or buck-derived topologies where cost and size drive discrete selection over integrated controllers. Use Value: SMA footprint enables dense layout; 50 A IFSM handles USB-C hot-plug inrush without derating. |

Use Scenario: 24 VDC auxiliary supply in PLC I/O modules operating in –40°C to +85°C ambient. IC Role / Device Role / Timing Role: Input-stage rectifier feeding linear regulator or low-noise switching converter for logic rails. Use Value: –65°C to +150°C Tj range ensures reliability across industrial temperature extremes; 5 µA IR prevents standby current drift. | Use Scenario: Standby power supply in refrigerators, washing machines, and HVAC controllers requiring continuous 3.3 V/5 V bias rails. IC Role / Device Role / Timing Role: Rectifier in capacitive-dropper or low-cost flyback circuit powering microcontroller and sensor interfaces. Use Value: Glass passivation prevents humidity-induced leakage increase during condensation cycles; RoHS compliance meets appliance regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | Ultrafast recovery (trr = 50 ns vs. S2D-13's ~2 µs), higher VF (1.3 V), same 200 V/1.5 A ratings | Better suited for high-frequency SMPS with snubberless operation; less optimal for 60 Hz line rectification due to higher conduction loss | Select when EMI reduction or reduced switching loss outweighs conduction loss penalty |
| Vishay 1N4004-T | Through-hole DO-41 package, 400 V VRRM, 1 A I(AV), higher VF (1.1 V @ 1 A), no RoHS exemption documentation | Requires manual insertion and wave soldering; lower current rating limits use in >5 W designs | Choose only for legacy through-hole production or prototyping where SMT infrastructure is unavailable |
Compared with MUR120 and 1N4004-T, S2D-13 offers optimal balance of low VF, SMT manufacturability, and RoHS compliance for cost-sensitive 60 Hz rectification-making it preferred for new designs targeting automated assembly and energy efficiency standards.

FAQ
What is the maximum allowable junction temperature for S2D-13?
The S2D-13 has a specified junction temperature range of –65°C to +150°C. Its thermal design must ensure that actual junction temperature under worst-case operating conditions (including ambient, copper pad area, and power dissipation) remains within this limit. Derating curves in the datasheet show I(AV) drops to zero at 150°C terminal temperature.
Can S2D-13 be used in full-wave bridge configurations?
No-S2D-13 is a single diode in SMA package and is not rated or characterized for bridge operation. For full-wave rectification, four discrete S2D-13 units may be assembled into a discrete bridge, but Diodes Incorporated does not specify or guarantee performance in such configurations; dedicated bridge rectifiers (e.g., DB102) are recommended instead.
Is S2D-13 suitable for use with capacitive input filters?
Yes, but with mandatory 20% current derating per the datasheet. Capacitive input filters cause high peak currents and increased RMS heating; therefore, the average forward current must be limited to 1.2 A (80% of 1.5 A) to maintain reliability and avoid thermal runaway under steady-state operation.
Does S2D-13 have a lead-free and RoHS-compliant version?
Yes-the standard S2D-13 is manufactured with matte tin lead-free plating and complies with RoHS Directive 2002/95/EC, including exemptions for glass and high-temperature solder per Annex Notes 5 and 7. No suffix change is required; RoHS compliance is inherent to the part number as shipped.
