Product details
Overview
RS2G-13 from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier with 400V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A, and 250ns reverse recovery time (trr), designed for high-efficiency AC/DC input stage rectification in compact power supplies and adapters.
For engineers reviewing the RS2G-13 datasheet, RS2G-13 pinout, RS2G-13 application, or RS2G-13 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (20 K/W) under defined PCB copper pad conditions, and surge capability (50A IFSM) in 8.3ms half-sine wave testing per JEDEC.
Technical Context
This device uses glass-passivated silicon die construction to achieve fast recovery performance while maintaining robust surge tolerance. Its 250ns trr enables operation in higher-frequency switching topologies where diode switching loss must be minimized.
The SMA package supports automated assembly and provides defined thermal resistance (20 K/W junction-to-terminal) when mounted on 5.0 mm² × 0.013 mm thick copper pads. Polarity is marked by a cathode band, and the UL 94V-0 molded plastic case ensures flame-retardant compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating limit in bridge or single-diode rectifier configurations. |
| IO @ TT=120°C | 1.5 A - Average rectified current rating at terminal temperature of 120°C; requires thermal management via PCB copper area. |
| VFM @ IF=1.5A | 1.3 V - Forward voltage drop at rated DC output current; directly impacts conduction loss and thermal load in continuous operation. |
| trr | 250 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, Irr=0.25A; determines switching loss and EMI generation in SMPS front-ends. |
| IFSM (8.3ms) | 50 A - Non-repetitive surge current rating per JEDEC Method; validates robustness against line transients and inrush events. |
| RJT | 20 K/W - Junction-to-terminal thermal resistance with specified 5.0 mm² copper pad; enables accurate junction temperature estimation during thermal design. |
Pinout & Package
SMA (DO-214AC) surface-mount package: cathode indicated by band-marked end; anode and cathode terminals are coplanar, solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for forward conduction path | Connected to AC source or transformer secondary; carries full load current during positive half-cycle. |
| Cathode | Output for forward conduction path | Connected to bulk capacitor or downstream regulator; polarity marking (band) prevents reverse installation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enhances reliability and moisture resistance without requiring hermetic sealing; suitable for industrial-grade reflow profiles. |
| Fast recovery (250ns) | Reduces switching losses and associated heat generation in 50–100 kHz SMPS input stages compared to standard rectifiers. |
| UL 94V-0 plastic case | Meets flammability safety requirements for end equipment certified to IEC/EN 62368-1 and similar standards. |
| 50A surge rating | Withstands repeated cold-start inrush and lightning-induced line surges without degradation in typical AC-input applications. |
Applications
| AC-DC Adapter Input Stage | USB PD Power Supply Rectification |
|---|---|
Use Scenario: Single-phase bridge rectification feeding 20–65W USB PD power supplies with universal AC input (90–264VAC). IC Role / Device Role / Timing Role: Fast recovery rectifier in full-wave bridge configuration; handles 50/60Hz line frequency with minimal conduction and switching loss. Use Value: 250ns trr and 1.3V VFM enable >88% efficiency at full load while meeting thermal limits on 2-layer PCBs. | Use Scenario: Output rectification in active-clamp flyback or LLC resonant converters delivering 20V@3A for USB PD 3.0. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode; recovers rapidly between switching cycles to minimize reverse conduction loss. Use Value: Low Cj (30 pF) and fast trr reduce ringing and EMI, easing EMC filter design without sacrificing efficiency. |
| Industrial Control Power Input | LED Driver Bulk Rectification |
Use Scenario: Input rectification for DIN-rail mounted 24V/48V DC power modules used in PLC I/O modules and motor drives. IC Role / Device Role / Timing Role: Primary rectifier in unregulated linear or buck-derived supply; operates continuously at elevated ambient temperatures up to +70°C.

IC Role / Device Role / Timing Role: High-reliability AC input stage handling long-life thermal cycling and line surges in outdoor environments. Use Value: 50A IFSM and glass-passivated die ensure >50,000-hour field life under repeated thermal stress and humidity exposure. |
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 = 150ns, IO = 1.0A, SMA package | Higher VRRM and faster trr but lower average current rating | Preferred where higher voltage margin or tighter EMI control is required, with acceptable 0.5A current reduction. |
| ON Semiconductor MUR160 | VRRM = 600V, trr = 50ns, IO = 1.0A, DO-41 through-hole | Ultra-fast recovery and through-hole mounting; not SMT-compatible | Select only if board layout permits through-hole assembly and sub-50ns trr is critical for ultra-high-frequency designs. |
Compared with RS2G-13, STTH1L06S offers higher voltage headroom and faster recovery but sacrifices 33% average current capacity, while MUR160 delivers superior speed in a legacy package incompatible with modern SMT lines-making RS2G-13 the optimal balance of current, speed, and manufacturability for mid-power SMPS.

FAQ
What is the maximum allowable junction temperature for RS2G-13?
The absolute maximum junction temperature is +150°C, as specified in the datasheet's operating temperature range (Tj = –65°C to +150°C). This limit applies under steady-state conditions with proper thermal design using the defined 5.0 mm² copper pad; exceeding it risks parametric shift and long-term reliability degradation.
Can RS2G-13 replace RS2J-13 in a 600V design?
No-RS2G-13 has a 400V VRRM rating, while RS2J-13 is rated for 600V. Substituting RS2G-13 in a 600V circuit risks reverse breakdown during line surges or peak AC conditions, especially under capacitive load derating. Voltage ratings must match or exceed system requirements.
Is RS2G-13 compliant with RoHS and REACH?
Yes-RS2G-13 is RoHS-compliant (lead-free terminations, homogeneous material restrictions met) and REACH-conformant, as confirmed by Diodes Incorporated's official product change notices and material declarations published on their website and authorized distributor portals.
How does the 20 K/W thermal resistance translate to real-world PCB layout?
RJT = 20 K/W assumes mounting on a 5.0 mm² (approx. 2.2 mm × 2.2 mm) copper pad, 0.013 mm thick. To achieve this, designers must use solid copper fill-not traces-and avoid thermal relief spokes. Smaller pads increase junction temperature proportionally, risking premature thermal shutdown or failure.
