Product details
Overview
S2DA from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode in SMA package, 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); it delivers low 1.15 V forward voltage drop at 1.5 A and is used in AC/DC input rectification stages of power supplies for consumer and industrial equipment.
For engineers reviewing the S2DA datasheet, S2DA pinout, S2DA application, or S2DA equivalent, key selection criteria include verified VRRM = 200 V, I(AV) = 1.5 A with thermal derating per Fig. 1, VF = 1.15 V @ 1.5 A, IRM = 5.0 µA @ 25°C, and SMA package compatibility with automated SMT assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier for 60 Hz AC inputs under resistive or inductive loads; capacitive loads require 20% current derating. Its glass passivated die construction ensures stable reverse leakage and high surge tolerance.
Thermal resistance junction-to-terminal is 20 °C/W when mounted on 5.0 mm² copper pads, enabling reliable operation up to +150°C junction temperature; typical capacitance is 20 pF at 1.0 MHz and 4.0 V reverse bias.
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 range. |
| I(AV) | 1.5 A @ TT = 100°C - Continuous DC output current capability with specified PCB copper pad heatsinking. |
| IFSM | 50 A - Surge withstand for 8.3 ms half-sine wave; supports inrush current handling in offline SMPS. |
| VF | 1.15 V @ IF = 1.5 A - Forward conduction loss directly impacts efficiency and thermal design in rectifier stage. |
| IRM | 5.0 µA @ 25°C - Low reverse leakage ensures minimal standby power loss and stable blocking performance. |
| RJT | 20 °C/W - Thermal resistance determines required PCB copper area for thermal management compliance. |
| Tj/TSTG | −65 to +150°C - Wide operating range supports industrial and automotive-adjacent environments. |
Pinout & Package

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 MURS220 | Ultrafast recovery (trr = 35 ns), VF = 1.25 V @ 1.5 A, same VRRM = 200 V, SMB package. | Better for high-frequency switching (e.g., PFC boost stages); higher VF increases conduction loss. | Select when fast recovery is needed; avoid if minimizing heat in linear-regulated outputs is critical. |
| Vishay VS-1N4004-M3/54 | Standard recovery (trr > 2 µs), VF = 1.1 V @ 1 A, VRRM = 400 V, DO-41 through-hole package. | Higher voltage margin but lower I(AV) = 1.0 A; requires manual soldering and larger board area. | Choose only for legacy through-hole designs where 400 V margin justifies derated current and assembly cost. |
Compared with MURS220 and 1N4004, S2DA offers optimal balance of low VF, 200 V rating, SMA SMT compatibility, and cost-making it preferred for space-constrained, thermally managed AC/DC front-ends where ultrafast recovery is unnecessary.

FAQ
What is the maximum allowable junction temperature for S2DA?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation up to this limit when thermal design meets the 20 °C/W junction-to-terminal resistance condition using 5.0 mm² copper pads. Derating begins above 100°C terminal temperature per Fig. 1 in the datasheet.
Can S2DA be used in full-wave bridge configurations?
No-S2DA is a single diode and not a bridge rectifier. It can be used as one leg in a discrete full-wave bridge (e.g., four S2DAs), but its pinout and ratings are defined for individual half-wave operation; dedicated bridge packages like DB102 offer better layout efficiency and thermal symmetry.
Is S2DA compatible with lead-free reflow profiles?
Yes-S2DA is supplied with matte tin plating and qualified for lead-free reflow per J-STD-020C, including peak temperatures up to 260°C. The SMA package's moisture sensitivity level is Level 1, eliminating bake requirements before assembly.
How does capacitive load affect S2DA's current rating?
When driving capacitive loads (e.g., bulk capacitor input filters), the average forward current rating must be reduced by 20% per the datasheet note-so I(AV) is limited to 1.2 A instead of 1.5 A-to prevent excessive peak current stress and premature wear-out due to high inrush currents.
