Product details
Overview
RS3JB-13-F from Diodes Incorporated is a 600 V, 3.0 A surface-mount fast recovery rectifier in SMB (DO-214AA) package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge capability - deployed in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the RS3JB-13-F datasheet, RS3JB-13-F pinout, RS3JB-13-F application, or RS3JB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (600 V), thermal resistance (25 K/W), junction-to-terminal cooling path, and fast recovery performance under high-frequency switching conditions.
Technical Context
This device uses glass-passivated silicon die with optimized carrier lifetime control to achieve fast recovery (trr = 150 ns) while maintaining low forward voltage (VFM = 1.3 V @ 3.0 A) and robust surge tolerance (IFSM = 100 A). It operates across –65 °C to +150 °C with UL 94V-0 molded plastic case.
The SMB package provides standardized solderable terminals per MIL-STD-202 Method 208, with cathode band polarity marking and 0.09 g mass. Thermal performance assumes mounting on a 5.0 mm² copper pad (0.013 mm thick) as heat sink per datasheet Note 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V repetitive reverse voltage, suitable for 400 VAC input rectification with safety margin |
| IO @ TT=75°C | 3.0 A - average forward current rating derated to 75 °C terminal temperature, not ambient |
| VFM @ IF=3.0A | 1.3 V - forward drop determines conduction loss (3.9 W max at full load) |
| trr | 150 ns - enables use in 100 kHz+ SMPS designs without excessive switching loss or EMI |
| IFSM | 100 A - withstands 8.3 ms half-sine surge, supporting inrush current handling in offline converters |
| RJT | 25 K/W - junction-to-terminal thermal resistance defines heatsinking requirement when mounted on PCB copper |
| IRM @ 125°C | 250 µA - leakage current at elevated temperature impacts standby power in high-reliability systems |
Pinout & Package
SMB (DO-214AA) surface-mount package with molded plastic case, cathode band marking, and solder-plated terminals compliant with MIL-STD-202 Method 208. Dimensions: 3.30–3.94 mm (L) × 4.06–4.57 mm (W) × 1.96–2.21 mm (H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for AC waveform positive half-cycle | Connected to AC source or transformer secondary; carries full load current during conduction |
| Cathode | Output for rectified DC | Feeds bulk capacitor or downstream converter; marked by band; must handle peak reverse voltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enhances humidity resistance and long-term reliability in unsealed industrial environments |
| Fast recovery (150 ns) | Reduces reverse recovery charge (Qrr), minimizing switching loss and diode-induced ringing |
| Low VF (1.3 V @ 3.0 A) | Lowers conduction loss vs. standard recovery rectifiers, improving efficiency in 230 VAC systems |
| UL 94V-0 plastic case | Meets flammability requirements for enclosed power supplies without additional potting |
| 100 A surge rating | Supports cold-start inrush without degradation, eliminating need for external NTC thermistors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | Same 600 V VRRM, 3 A IO, but TO-277 package (lower thermal resistance: 15 K/W); trr = 120 ns | Requires different footprint and reflow profile; better suited for higher-power density layouts | Choose when board-level thermal management is constrained and lower trr is critical |
| ES3J-E3/57T | Same SMB package, 600 V VRRM, but higher VF (1.7 V @ 3 A); trr = 200 ns; IFSM = 80 A | Higher conduction loss and reduced surge margin; acceptable only in cost-sensitive, low-dissipation designs | Choose only if BOM cost reduction outweighs 0.4 V VF penalty and 20% lower surge rating |
Compared with STTH3L06S and ES3J-E3/57T, RS3JB-13-F delivers optimal balance of SMB footprint compatibility, 150 ns recovery, and 100 A surge headroom - making it preferred for space-constrained industrial power supplies requiring field-proven reliability.

FAQ
What is the maximum allowable junction temperature for RS3JB-13-F?
The absolute maximum junction temperature is +150 °C, consistent with its rated operating range. Derating begins at terminal temperature >75 °C per Figure 1; sustained operation above 150 °C risks irreversible parametric shift or bond-wire failure.
Can RS3JB-13-F replace a standard recovery rectifier in an existing 60 Hz transformer-based supply?
Yes - its 600 V VRRM and 3.0 A IO meet or exceed typical 1N5408 specs, and its faster recovery introduces no risk in low-frequency operation. However, its lower VF reduces conduction loss, improving efficiency and thermal margin.
Is RS3JB-13-F suitable for use in a synchronous rectification circuit?
No - it is a unidirectional, passive PN-junction rectifier, not a MOSFET-based synchronous device. It cannot be actively controlled or gate-driven; it functions only as a voltage-controlled switch with inherent recovery delay.
Does RS3JB-13-F require a heatsink in typical 3.0 A operation?
Not necessarily - with proper PCB copper area (5.0 mm² pad per datasheet Note 1), its 25 K/W RJT allows safe operation at 75 °C terminal temperature. Heatsinks are only needed if ambient exceeds 70 °C or airflow is restricted.
