Product details
Overview
RS2M-13 from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A, and 500ns reverse recovery time (trr), designed for high-efficiency AC/DC front-end rectification in offline switch-mode power supplies.
For engineers reviewing the RS2M-13 datasheet, RS2M-13 pinout, RS2M-13 application, or RS2M-13 equivalent, key selection criteria include VRRM rating for input surge margin, trr for EMI-sensitive high-frequency designs, thermal resistance (20 K/W) for board-level heatsinking, and SMA package compatibility with automated SMT assembly.
Technical Context
This device is a single-phase, silicon planar junction, glass-passivated fast recovery diode optimized for 60Hz–100kHz rectification. Its 500ns trr enables reduced switching losses compared to standard recovery rectifiers, while the 1.3V VFM at 1.5A balances conduction loss and thermal performance.
The SMA package provides a junction-to-terminal thermal resistance of 20 K/W when mounted on 5.0 mm² copper pads, supporting continuous 1.5A operation up to 120°C terminal temperature. Surge capability is rated at 50A (8.3ms half-sine) per JEDEC method.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak line transients in universal-input (85–265VAC) SMPS without breakdown |
| IO @ TT=120°C | 1.5 A - Maximum continuous DC output current with PCB copper pad heatsinking |
| VFM @ IF=1.5A | 1.3 V - Conduction loss of 1.95W at full load, dictating thermal design margin |
| trr | 500 ns - Limits reverse recovery charge (Qrr ≈ 150nC), critical for EMI filtering in high-frequency converters |
| IFSM (8.3ms) | 50 A - Survives cold-start inrush into bulk capacitors without degradation |
| RJT | 20 K/W - Requires ≥5.0 mm² copper pad per terminal for safe thermal derating |
Pinout & Package
SMA (DO-214AC) surface-mount package: cathode marked by band on body; anode and cathode terminals are coplanar, gull-wing leads compatible with reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for AC waveform positive half-cycle | Connected to transformer secondary or bridge input; carries full load current during conduction |
| Cathode | Output for rectified DC | Feeds bulk capacitor; polarity marking (band) ensures correct orientation in layout |
Key Features

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 | VRRM = 600V, trr = 35ns, VF = 1.15V @ 1A | Limited to 277VAC systems; superior speed but lower voltage margin | Select when ultra-low EMI is required and input voltage is ≤300VAC |
| ON Semiconductor MUR160 | VRRM = 600V, trr = 75ns, IO = 1A, TO-220AC package | Through-hole mounting; higher thermal mass but no SMT compatibility | Choose for legacy through-hole production or higher transient thermal absorption needs |
Compared with RS2M-13, STTH1L06S offers faster switching but insufficient VRRM for universal-input designs, while MUR160 trades SMT scalability and voltage rating for mechanical ruggedness and thermal inertia-making RS2M-13 optimal for new SMT-based 1000V-rated power supplies.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in high-reliability power management and signal integrity solutions for industrial, computing, and consumer markets.
The RS2x series targets cost-sensitive, high-volume AC/DC rectification applications where fast recovery, surge robustness, and SMT manufacturability are prioritized over ultra-low VF or sub-100ns trr.
FAQ
What is the maximum allowable PCB copper pad area for RS2M-13 thermal performance?
The datasheet specifies 5.0 mm² (0.013 mm thick) copper pads per terminal as the reference condition for the 20 K/W RJT rating. Larger pads improve thermal performance linearly up to practical limits; doubling pad area typically reduces RJT by ~15%. Excessive copper may impede solder paste release during reflow.
Can RS2M-13 be used in a full-wave bridge configuration?
Yes-RS2M-13 is a single die rectifier and is commonly used in discrete full-wave bridge layouts. Four units can form a 1000V, 1.5A bridge. Ensure symmetrical PCB layout and thermal coupling to avoid current imbalance; derate total output current to 1.2A if ambient exceeds 60°C.
Does RS2M-13 meet RoHS and REACH requirements?
Yes-RS2M-13 is RoHS 2011/65/EU compliant and REACH SVHC-free per Diodes Incorporated's material declarations. The lead finish is matte tin, and the molding compound contains no halogenated flame retardants beyond UL 94V-0 requirements.
How does reverse recovery behavior change at elevated temperature?
At Tj = 125°C, trr increases to approximately 750ns (vs. 500ns at 25°C), and IR rises to 200µA (vs. 5µA). This is documented in Figure 4 and Note 3 of DS15004 Rev. E-2. Designers must verify EMI filter margins under worst-case thermal conditions.
