Product details
Overview
RS1GB-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode in SMB package, rated for 400 V peak repetitive reverse voltage, 1.0 A average forward current, and 150 ns reverse recovery time. It features glass passivated die construction, 30 A non-repetitive surge capability, and RoHS-compliant lead-free finish - used in AC/DC input stages of compact power adapters and offline SMPS.
For engineers reviewing the RS1GB-13-F datasheet, RS1GB-13-F pinout, RS1GB-13-F application, or RS1GB-13-F equivalent, key selection criteria include reverse recovery time (tRR = 150 ns), forward voltage drop (VFM = 1.3 V @ 1.0 A), thermal resistance (RθJT = 20 °C/W), and SMB package compatibility with automated SMT assembly lines.
Technical Context
This fast recovery rectifier employs a planar epitaxial silicon junction with glass passivation to ensure stable reverse leakage and consistent switching performance across temperature. Its 150 ns tRR enables efficient operation in 50–100 kHz flyback and forward converters where reduced switching loss is critical.
The device operates with a maximum forward voltage of 1.3 V at 1.0 A and exhibits only 5.0 µA peak reverse current at 25°C under full-rated blocking voltage - supporting high-efficiency, low-heat-rise designs in space-constrained power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands up to 400 V repetitive reverse voltage without breakdown in AC line rectification. |
| IO | 1.0 A @ TT = +120°C - Continuous DC output current rating under thermally anchored terminal conditions. |
| tRR | 150 ns - Fast recovery minimizes reverse conduction loss during switching transitions in SMPS. |
| VFM | 1.3 V @ IF = 1.0 A - Low forward drop reduces conduction loss and thermal load in high-duty-cycle applications. |
| IFSM | 30 A - Handles short-duration inrush surges common during cold-start of power supplies. |
| RθJT | 20 °C/W - Junction-to-terminal thermal resistance enables direct PCB copper pour heat sinking without heatsink. |
Pinout & Package
SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 rated, cathode band polarity marking, matte tin annealed terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to AC input or transformer secondary; must withstand peak inverse voltage and surge current. |
| Cathode | Forward current exit / reverse blocking node | Connected to bulk capacitor or switching node; marked by band; carries full output current and reverse blocking stress. |
Key Features
| Feature | Design Value |
|---|---|

| Fast recovery (150 ns) | Reduces switching losses in 50–100 kHz flyback converters versus standard rectifiers (>500 ns). |
| 30 A surge rating | Survives cold-start inrush in universal-input AC/DC adapters without derating or snubbing. |
| RoHS & "Green" compliant | Meets EU RoHS 3 and halogen/antimony limits (<900 ppm Br/Cl, <1000 ppm Sb) for eco-sensitive end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | Same SMB package, 400 V VRRM, but tRR = 50 ns (faster), VFM = 1.25 V, IFSM = 35 A. | Better suited for higher-frequency (>200 kHz) topologies requiring lower switching loss. | Select when optimizing for ultra-low tRR in resonant or quasi-resonant converters. |
| Vishay VS-1N4937-M3/54 | SMB package, 400 V VRRM, tRR = 200 ns (slower), VFM = 1.3 V, IFSM = 30 A, same RθJT. | Marginally slower recovery increases conduction loss in 100 kHz+ designs. | Acceptable where cost sensitivity outweighs minor efficiency trade-off in legacy 50–60 kHz designs. |
Compared with MUR140 and VS-1N4937-M3/54, RS1GB-13-F delivers balanced performance: identical IFSM and thermal resistance to Vishay's part but faster tRR, and lower cost than ON Semi's ultra-fast variant while retaining sufficient speed for mainstream 50–100 kHz flyback use.

FAQ
What is the maximum operating temperature for RS1GB-13-F?
The RS1GB-13-F has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RθJT = 20 °C/W) allows safe operation at 1.0 A average current up to +120°C terminal temperature, provided adequate PCB copper area is used for heat spreading per the recommended pad layout.
Is RS1GB-13-F suitable for use in synchronous rectification circuits?
No - RS1GB-13-F is a unidirectional fast recovery diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. It serves as a passive rectifier in non-synchronous topologies like standard flyback or forward converters where simplicity and cost outweigh efficiency gains from active rectification.
Does RS1GB-13-F require a heatsink in typical applications?
No external heatsink is required. With RθJT = 20 °C/W and 1.0 A IO at +120°C terminal temperature, thermal management is achieved via PCB copper pour - the SMB package's low mass and direct thermal path to the board enable sufficient heat dissipation in most 5–24 W applications using standard 2-layer FR-4 with ≥100 mm² copper area per terminal.
How does RS1GB-13-F differ from RS1G-13-F?
RS1GB-13-F uses the SMB (DO-214AA) package, while RS1G-13-F uses the smaller SMA (DO-214AC) package. Both share identical electrical specs (400 V VRRM, 1.0 A IO, 150 ns tRR), but RS1GB-13-F offers higher thermal mass (0.093 g vs. 0.064 g), lower RθJA in PCB-mounted condition, and greater mechanical robustness for high-vibration environments.
