Product details
Overview
RS3DB-13-F from Diodes Incorporated is a 200 V, 3.0 A surface-mount fast recovery rectifier in SMB package with 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the RS3DB-13-F datasheet, RS3DB-13-F pinout, RS3DB-13-F application, or RS3DB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (200 V), average rectified current (3.0 A @ TT = 75°C), thermal resistance (25 °C/W junction-to-terminal), fast recovery time (150 ns), and RoHS-compliant matte tin plating.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for high-efficiency switching power conversion. Its glass-passivated die construction ensures stable performance under thermal cycling, while the 150 ns recovery time enables operation in 50–100 kHz SMPS topologies without excessive switching loss.
The SMB package provides defined thermal path to PCB copper pads (5.0 mm², 0.013 mm thick), delivering 25 °C/W junction-to-terminal thermal resistance. Polarity is marked by cathode band; moisture sensitivity level is Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltage up to 200 V without breakdown in AC line rectification. |
| IO @ TT=75°C | 3.0 A - Sustains continuous average forward current of 3.0 A when terminal temperature is held at 75°C. |
| VFM @ IF=3.0A | 1.3 V - Forward conduction loss of 3.9 W at full load, enabling efficient thermal management in compact layouts. |
| trr | 150 ns - Enables use in 50–100 kHz switch-mode power supplies with minimal reverse recovery loss. |
| IFSM | 100 A - Survives 8.3 ms half-sine surge events (e.g., cold-start inrush) without failure. |
| RθJT | 25 °C/W - Junction-to-terminal thermal resistance measured on standard 5.0 mm² copper pad; defines heatsinking requirement. |
| IRM @ 125°C | 250 µA - Low leakage at elevated temperature preserves efficiency in high-ambient environments. |
Pinout & Package
SMB (DO-214AA) surface-mount package: molded plastic case rated UL 94V-0, cathode indicated by band on body, matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must handle 3.0 A continuous and 100 A surge. |
| Cathode | Forward current exit point | Connected to output capacitor or DC bus; polarity marking (band) prevents reverse installation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates need for hermetic sealing while maintaining reliability in humid or contaminated environments. |
| Fast recovery time (150 ns) | Reduces switching loss and EMI generation in high-frequency rectification stages. |
| Lead-free / RoHS-compliant finish | Meets EU Directive 2002/95/EC with matte tin plating compatible with lead-free reflow profiles. |
| Green molding compound | Halogen- and antimony-free epoxy supports environmental compliance without compromising mechanical robustness. |

Use Value: Low CT (50 pF) and fast recovery preserve signal integrity in sub-1 MHz sensor interfaces. |
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 | 600 V VRRM, same SMB package, 1.7 V VFM @ 3 A, 50 ns trr | Higher voltage rating suits universal-input PFC stages; higher VF increases conduction loss | Select when >400 V blocking required; avoid if thermal budget is tight due to higher VF |
| ON Semiconductor MUR320 | 200 V VRRM, same IO, 1.25 V VFM @ 3 A, 75 ns trr, SMB package | Lower VF and faster trr improve efficiency in high-frequency designs but require tighter layout for EMI control | Prefer for new designs targeting <100 kHz SMPS where lowest loss is critical |
Compared with STTH3L06S and MUR320, RS3DB-13-F offers balanced trade-offs: lower cost than MUR320, better thermal resistance than STTH3L06S, and proven field reliability in industrial rectifier applications where 200 V rating suffices.

FAQ
What is the maximum operating temperature for RS3DB-13-F?
The RS3DB-13-F has an operating and storage temperature range of –65°C to +150°C. Its thermal design assumes terminal temperature (TT) ≤ 75°C for rated 3.0 A average current; junction temperature must remain below 150°C under all conditions, enforced via PCB copper pad heatsinking per datasheet Figure 1 derating curve.
Is RS3DB-13-F suitable for use in a bridge rectifier configuration?
Yes - RS3DB-13-F is commonly used as one leg in discrete full-wave bridge configurations. Its 200 V VRRM and 100 A IFSM support standard 115/230 VAC inputs; however, each diode sees only half the bridge's peak inverse voltage, so pairing with identical devices is recommended for balanced stress distribution.
Does RS3DB-13-F require a heatsink in typical applications?
No dedicated heatsink is required. The SMB package relies on PCB copper pads (minimum 5.0 mm² per terminal) as its thermal interface. At 3.0 A and 75°C terminal temperature, the 25 °C/W RθJT yields ~97.5°C junction rise above ambient - well within the 150°C limit if board layout follows datasheet-recommended pad dimensions and thermal vias.
How does the green molding compound affect reliability?
The halogen- and antimony-free green molding compound meets IEC 61249-2-21 requirements and eliminates corrosive outgassing risks in sealed enclosures. Accelerated testing shows no degradation in insulation resistance or mechanical adhesion versus standard epoxy, with equivalent long-term humidity resistance (J-STD-020 Level 1).
