Product details
Overview
RS2G-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode in SMB package, rated for 400 V peak repetitive reverse voltage (VRRM), 1.5 A average rectified output current (IO), and 150 ns reverse recovery time (trr). It features glass passivated die construction, 50 A non-repetitive surge capability, and RoHS-compliant lead-free plating - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the RS2G-13-F datasheet, RS2G-13-F pinout, RS2G-13-F application, or RS2G-13-F equivalent, key selection criteria include its 400 V blocking rating, fast 150 ns recovery for high-frequency switching efficiency, thermal resistance of 20 °C/W, and SMB package compatibility with automated SMT assembly lines.
Technical Context
This device operates as a unidirectional power rectifier in single-phase, half-wave configurations with resistive or inductive loads. Its fast recovery time enables reduced switching losses in 20–100 kHz SMPS topologies, while the glass passivated junction ensures stable leakage performance across -65°C to +150°C operating range.
The SMB package provides 0.09 g mass and UL 94V-0 molded plastic housing with matte tin-plated terminals. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1, supporting reflow without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification up to 280 V RMS AC line (e.g., universal 85–265 VAC supplies) |
| IO @ TT = 120°C | 1.5 A - continuous DC output current capability with PCB copper pad heatsinking |
| trr | 150 ns - enables efficient operation in 50–100 kHz flyback and forward converters |
| VFM @ IF = 1.5 A | 1.3 V - forward conduction loss of ~1.95 W at full load, manageable with SMB thermal resistance |
| IFSM (8.3 ms) | 50 A - withstands inrush surges from cold-started capacitive inputs without failure |
| RθJT | 20 °C/W - junction-to-terminal thermal resistance measured on 5.0 mm² copper pad, enabling thermal design predictability |
Pinout & Package
SMB (DO-214AA) surface-mount package: molded plastic body, cathode band marking, matte tin-plated terminals, J-STD-020 Level 1 moisture sensitivity, UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry during forward conduction | Connected to AC source or transformer secondary; requires trace width sufficient for 1.5 A continuous current |
| Cathode | Output current exit during forward conduction | Connected to bulk capacitor or downstream converter; polarity marking critical for board assembly verification |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates need for hermetic sealing while maintaining IR stability and humidity resistance over life |
| 150 ns reverse recovery time | Reduces turn-off switching loss and EMI generation compared to standard recovery diodes (e.g., 1N4007) |
| 50 A surge rating (8.3 ms) | Survives repeated cold-start inrush events in offline power supplies without degradation |
| Lead-free, halogen-free "Green" construction | Complies with RoHS 3 (2015/863/EU) and automotive change control requirements when qualified |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Front-end rectification in 30–100 W open-frame power supplies for factory automation controllers. IC Role / Device Role / Timing Role: Unidirectional current steering device converting 100–240 VAC input to pulsating DC prior to bulk capacitance and PWM regulation. Use Value: 150 ns trr minimizes switching node ringing and reduces snubber losses in 65 kHz flyback designs. | Use Scenario: Bridge or single-diode rectification in constant-current LED drivers for street lighting. IC Role / Device Role / Timing Role: High-reliability AC input protection and rectification stage handling 400 V transients and thermal cycling. Use Value: 400 V VRRM and -65°C to +150°C TJ range ensure robustness in outdoor enclosures with wide ambient swings. |
| Consumer Adapter Secondary Side | DC-DC Converter Input Stage |
Use Scenario: Output rectification in low-cost 12 V/2 A wall adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Fast-recovery output diode synchronized with primary-side controller timing to reduce conduction loss. Use Value: 1.3 V VFM at 1.5 A yields lower conduction loss than Schottky alternatives above 100 V rating. | Use Scenario: Input-stage rectification feeding isolated DC-DC modules in telecom power shelves. IC Role / Device Role / Timing Role: Surge-tolerant front-end diode protecting downstream DC-DC stages from line transients and hot-swap events. Use Value: 50 A IFSM rating allows safe operation during 48 V hot-plug insertion without derating. |
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 | 600 V VRRM, 1.0 A IO, 75 ns trr, TO-277 package | Higher voltage rating but lower current; smaller footprint but no tape-and-reel SMB option | Preferred where >400 V margin or faster recovery is required, but requires layout revision |
| ON Semi MUR160 | 600 V VRRM, 1.0 A IO, 60 ns trr, DO-41 through-hole | Through-hole mounting; incompatible with SMT lines; higher trr sensitivity to temperature drift | Only suitable for legacy through-hole designs or prototyping; not drop-in for RS2G-13-F |
Compared with STTH1L06S and MUR160, RS2G-13-F offers optimal balance of 400 V rating, 1.5 A current, SMB SMT compatibility, and 150 ns recovery - making it ideal for cost-sensitive, volume-manufactured industrial power supplies requiring automated assembly.

FAQ
What is the maximum junction temperature for RS2G-13-F?
The RS2G-13-F has an operating junction temperature range of -65°C to +150°C, verified per datasheet DS15004 Rev. 12-2. Thermal design must ensure that under worst-case load and ambient conditions, the junction does not exceed 150°C - achievable with proper PCB copper area and airflow per the 20 °C/W RθJT specification.
Is RS2G-13-F qualified for automotive use?
RS2G-13-F itself is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., RS2GHE3_A/H) with PPAP documentation, IATF 16949 manufacturing, and AEC-Q101 stress testing. Standard RS2G-13-F is intended for industrial and commercial applications unless explicitly qualified and marked.
How does RS2G-13-F compare to standard recovery diodes like 1N4007?
RS2G-13-F delivers 150 ns reverse recovery time versus 30 µs for 1N4007, reducing switching losses and EMI in high-frequency SMPS. It also supports higher surge current (50 A vs. 30 A) and operates reliably up to 150°C junction temperature - unlike 1N4007's 125°C limit - making it suitable for modern compact power designs.
What is the recommended PCB pad layout for RS2G-13-F in SMB package?
Per Diodes' suggested layout in DS15004, use pad dimensions: C = 4.30 mm, G = 1.80 mm, X = 2.50 mm, X1 = 6.80 mm, Y = 2.30 mm. Maintain 5.0 mm² copper area per terminal for thermal performance, and ensure solder mask defined pads to prevent bridging during reflow.
