Product details
Overview
RS2D-13 from Diodes Incorporated is a 200 V, 1.5 A surface-mount fast recovery rectifier in SMA package with 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge rating - used in AC/DC input stage of compact offline power supplies.
For engineers reviewing the RS2D-13 datasheet, RS2D-13 pinout, RS2D-13 application, or RS2D-13 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (20 K/W) under PCB copper pad heatsinking, and trr-driven switching loss in 50–100 kHz flyback converters.
Technical Context
This device employs glass-passivated silicon die for robustness against moisture and mechanical stress, enabling reliable operation across –65 °C to +150 °C junction temperature range. Its fast recovery (trr = 150 ns) minimizes reverse recovery charge (Qrr), reducing EMI and conduction losses in high-frequency rectification.
The SMA package features solderable terminals compliant with MIL-STD-202 Method 208 and UL 94V-0 flammability rating. Polarity is marked by cathode band; mounting orientation is unrestricted, supporting automated placement on dense PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; sets minimum input bridge rating for 170 VAC mains-derived designs. |
| IO @ TT=120°C | 1.5 A - Continuous average forward current with terminal temperature limited to 120 °C; requires ≥5 mm² copper pad for thermal management. |
| VFM @ IF=1.5A | 1.3 V - Forward voltage drop defining conduction loss (1.95 W at full load); impacts efficiency and heatsink sizing in low-voltage output stages. |
| trr | 150 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, Irr=0.25A; determines switching loss and snubber design in 50–100 kHz SMPS. |
| IFSM | 50 A - Non-repetitive surge rating (8.3 ms half-sine); withstands inrush currents during cold-start of universal-input adapters. |
| RJT | 20 K/W - Junction-to-terminal thermal resistance with 5.0 mm² × 0.013 mm Cu pad; enables direct thermal path to PCB without external heatsink. |
Pinout & Package
SMA package: molded plastic case with solder-plated terminals; cathode identified by band; weight ≈ 0.065 g; UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input node for AC or switched DC source | Connects to transformer secondary or switching node; must handle peak inverse voltage and surge current. |
| Cathode | Output node for rectified DC | Feeds bulk capacitor or downstream converter; polarity marking ensures correct orientation in bridge or single-diode configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Eliminates need for hermetic sealing while maintaining humidity resistance and long-term reliability in industrial environments. |
| Fast recovery (150 ns) | Reduces reverse recovery charge (Qrr) to <100 nC, lowering switching losses and EMI generation in high-frequency SMPS. |
| UL 94V-0 plastic case | Meets flame-retardancy requirements for end-equipment safety certifications including IEC 62368-1 and UL 62368-1. |
| Automated assembly compatible | Standardized SMA footprint supports pick-and-place accuracy and reflow soldering per IPC-J-STD-020 moisture sensitivity level (MSL) 1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | Same 200 V VRRM, but 1.0 A IO rating and 75 ns trr; TO-277 package (higher thermal mass). | Better suited for lower-current, higher-speed applications where faster recovery outweighs current capacity. | Select when trr <100 ns is critical and average current ≤1.0 A; verify TO-277 footprint compatibility. |
| ON Semi MUR120 | 200 V VRRM, 1.0 A IO, 75 ns trr, DO-41 through-hole package; higher RJT (~50 K/W). | Preferred for legacy through-hole designs or prototyping where manual soldering is acceptable. | Choose only for hand-assembled prototypes or cost-sensitive low-volume builds; avoid in thermally constrained SMT layouts. |
Compared with RS2D-13, STTH1L06S offers faster recovery but lower current handling, while MUR120 trades SMT compatibility and thermal performance for through-hole simplicity - making RS2D-13 optimal for production-grade 1.5 A SMT rectification with balanced speed, ruggedness, and manufacturability.

FAQ
What is the maximum allowable PCB copper pad area for optimal thermal performance of RS2D-13?
The datasheet specifies thermal resistance (RJT = 20 K/W) is measured using a 5.0 mm² copper pad, 0.013 mm thick. Increasing pad area beyond this yields diminishing returns; doubling pad size typically improves RJT by only 10–15%. For continuous 1.5 A operation at 120 °C terminal temperature, maintain at least this pad size and ensure no thermal vias are blocked by solder mask.
Can RS2D-13 be used in place of a standard 1N4007 in a 12 V adapter?
No - RS2D-13 has 200 V VRRM versus 1N4007's 1000 V, making it unsuitable for 120 VAC or 230 VAC inputs without additional voltage clamping. However, it outperforms 1N4007 in speed (150 ns vs. ~2 µs trr) and forward loss (1.3 V vs. ~1.1 V at 1 A), so it is appropriate only in designs where VRRM margin is verified and high-frequency switching benefits are needed.
Is RS2D-13 compliant with RoHS and REACH regulations?
Yes - RS2D-13 is RoHS 2011/65/EU and REACH SVHC-compliant, as confirmed by Diodes Incorporated's official material declarations. The SMA package uses lead-free solder plating and halogen-free molding compound, meeting JEDEC J-STD-020 moisture sensitivity level (MSL) 1 for unlimited floor life at ≤30 °C/60% RH.
Does RS2D-13 require derating when used with capacitive loads?
Yes - the datasheet explicitly states that for capacitive loads, average rectified current (IO) must be derated by 20%. At 120 °C terminal temperature, this reduces usable current from 1.5 A to 1.2 A. This derating accounts for high inrush current peaks that increase junction temperature beyond steady-state assumptions, particularly during cold-start of bulk-capacitor-fed supplies.
