Product details
Overview
RS1JB-13 from Diodes Incorporated is a 1.0A surface-mount fast recovery rectifier in SMB package, rated for 600V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 1.0A, and 250ns reverse recovery time - designed for high-efficiency AC/DC front-end rectification in compact power supplies and LED drivers.
For engineers reviewing the RS1JB-13 datasheet, RS1JB-13 pinout, RS1JB-13 application, or RS1JB-13 equivalent, key selection criteria include its 600V blocking capability, fast 250ns recovery for reduced switching loss, SMB thermal resistance of 20°C/W, and RoHS-compliant matte tin plating suitable for lead-free reflow assembly.
Technical Context
This device employs glass-passivated silicon die construction to ensure stable reverse leakage and robust surge tolerance. Its fast recovery behavior is characterized under standardized test conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A (per Figure 5), enabling reliable operation in 50–100kHz SMPS topologies.
The SMB package provides higher thermal dissipation than SMA (RJT = 20°C/W vs. 25°C/W), supports automated pick-and-place, and maintains polarity via cathode band marking. It is rated for continuous operation from –65°C to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands transient surges up to 600V in bridge or single-phase rectifier configurations without breakdown. |
| IO @ TT=120°C | 1.0 A - Continuous average output current rating when terminal temperature is held at 120°C, defining usable DC output capacity. |
| VFM @ IF=1.0A | 1.3 V - Forward conduction loss per diode at rated current, directly impacting efficiency and thermal design in low-voltage secondary-side rectification. |
| trr | 250 ns - Measured recovery time under IF=0.5A/IR=1.0A/Irr=0.25A; enables use in medium-frequency switchers with minimal commutation loss. |
| IFSM (8.3ms) | 30 A - Non-repetitive surge rating allows handling of inrush currents during cold-start or line transients without failure. |
| IRM @ 25°C | 5.0 µA - Low reverse leakage ensures minimal standby power loss in high-impedance bias networks or sensing circuits. |
Pinout & Package
SMB (DO-214AA) surface-mount package: molded plastic case (UL 94V-0), cathode indicated by band on body, solderable matte tin terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to AC input or transformer secondary; must withstand full surge current and reverse voltage stress. |
| Cathode | Current exit point during forward conduction | Marked with band; ties to output capacitor or load return; defines polarity in bridge configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable IR over temperature and humidity, eliminating need for conformal coating in industrial environments. |
| Fast 250ns recovery | Reduces switching losses in 50–100kHz flyback and forward converters, improving overall system efficiency by ~0.5–1.2%. |
| 30A IFSM rating | Supports direct connection to unfiltered rectified mains or high-inertia motor drives without external fusing. |
| RoHS-compliant matte tin finish | Enables compatibility with Pb-free reflow profiles (peak 260°C) and eliminates post-solder cleaning requirements. |
Applications
| LED Driver Secondary Rectification | Industrial AC/DC Adapter Input Stage |
|---|---|
Use Scenario: High-density constant-current LED driver operating from 120/230VAC with active PFC and quasi-resonant flyback. IC Role / Device Role / Timing Role: Fast recovery output rectifier in secondary-side synchronous or diode-based rectification stage. Use Value: 250ns trr minimizes reverse recovery loss during high-frequency switching, preserving >90% efficiency at 60W output. | Use Scenario: DIN-rail mounted 24V/5A industrial power supply with universal input and wide ambient range (–25°C to +70°C). IC Role / Device Role / Timing Role: Primary-side bridge rectifier diode in discrete full-wave configuration before bulk capacitor. Use Value: 600V VRRM and 30A IFSM handle 305VAC peaks and cold-start surges without derating or parallel devices. |
| USB-C PD Power Delivery Module | Smart Home Gateway Power Supply |

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 SMB package, 600V VRRM, but 1.7V VFM @ 1A and 50ns trr - higher conduction loss, faster recovery. | Better suited for high-frequency ZVS/ZCS topologies where trr dominates loss; less optimal for cost-sensitive mid-power adapters. | Choose STTH1L06S only if system operates >200kHz and thermal margin permits higher VFM. |
| ON Semi MUR160 | SMB package, 600V VRRM, 1.25V VFM @ 1A, 75ns trr - lower forward drop, significantly faster recovery. | Requires tighter layout due to faster dv/dt sensitivity; may need snubbing in noisy EMI environments. | Select MUR160 when optimizing for lowest possible conduction + switching loss in space-constrained designs with controlled layout. |
Compared with RS1JB-13, STTH1L06S trades higher forward loss for ultrafast recovery, while MUR160 delivers both lower VFM and faster trr but demands stricter PCB layout control - RS1JB-13 balances cost, robustness, and performance for mainstream 50–100kHz industrial and consumer power supplies.

FAQ
What is the maximum junction temperature for RS1JB-13?
The RS1JB-13 has a specified operating junction temperature range of –65°C to +150°C. This rating is validated under steady-state thermal conditions with proper PCB copper area (≥1 cm² thermal pad) and ambient ≤125°C. Derating applies above 120°C terminal temperature per Figure 1.
Is RS1JB-13 compatible with lead-free reflow processes?
Yes - RS1JB-13 features matte tin-plated terminals qualified for Pb-free reflow soldering per J-STD-020C, with peak temperature tolerance up to 260°C for 30 seconds. Its moisture sensitivity level is 1, eliminating bake requirements prior to assembly.
How does RS1JB-13 differ from RS1J-13?
RS1JB-13 uses the SMB (DO-214AA) package, while RS1J-13 uses the smaller SMA (DO-214AC). The SMB version offers lower thermal resistance (20°C/W vs. 25°C/W), higher surge rating margin, and improved mechanical robustness - making it preferred for higher-power or thermally demanding layouts.
Can RS1JB-13 be used in a full-bridge rectifier configuration?
Yes - RS1JB-13 is rated for 600V VRRM and 30A non-repetitive surge, making it suitable for discrete full-bridge rectifiers on 230VAC inputs. Each diode sees ≤400V peak reverse voltage in standard bridge operation, well within its 600V rating and derating margin.
