Product details
Overview
RS1DB-13 from Diodes Incorporated is a 200 V, 1.0 A surface-mount fast recovery rectifier in SMA package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 1.0 A, and 30 A non-repetitive surge capability - used in AC/DC input stage of compact switch-mode power supplies.
For engineers reviewing the RS1DB-13 datasheet, RS1DB-13 pinout, RS1DB-13 application, or RS1DB-13 equivalent, key selection criteria include peak reverse voltage rating, fast recovery performance for high-frequency rectification, thermal resistance (20 °C/W), and RoHS-compliant lead-free plating suitability for automated SMT assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier with glass-passivated die construction to ensure stable reverse leakage and rugged surge tolerance. Its 150 ns trr enables efficient operation up to ~100 kHz switching frequencies in offline SMPS front-end stages.
Rated for 120 °C terminal temperature operation, it supports derated average current under elevated ambient conditions per Figure 1. The cathode band polarity marking and solderable matte tin terminals comply with MIL-STD-202 and J-STD-020C Level 1 moisture sensitivity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V repetitive reverse voltage, suitable for 115 VAC input with safety margin |
| IO @ TT=120°C | 1.0 A - continuous average forward current at 120 °C terminal temperature, defining thermal design limit |
| trr | 150 ns - fast recovery minimizes switching losses and EMI in high-frequency rectification |
| VFM @ IF=1.0A | 1.3 V - low forward drop reduces conduction loss and improves efficiency in low-voltage output designs |
| IFSM | 30 A - handles 8.3 ms half-sine surge, supporting inrush current protection without failure |
| RJT | 20 °C/W - junction-to-terminal thermal resistance guides heatsinking and PCB copper area requirements |
| IRM @ 25°C | 5.0 µA - low reverse leakage ensures minimal standby power loss in high-impedance circuits |
Pinout & Package
SMA package: molded plastic case (UL 94V-0), cathode indicated by band on body; terminals are solder-plated for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input connection point | Accepts alternating input; must be routed with adequate creepage for 200 V isolation |
| Cathode | DC output connection point | Delivers rectified positive output; marked by visible band for orientation verification |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and humidity resistance in unsealed industrial environments |
| Fast recovery (150 ns) | Reduces reverse recovery charge (Qrr), lowering switching loss in 50–100 kHz SMPS designs |
| Lead-free / RoHS compliant | Enables compliance with EU WEEE/RoHS directives without process change for SMT lines |
| JEDEC-standard SMA footprint | Ensures mechanical compatibility with standard pick-and-place nozzles and reflow profiles |
Applications
| AC/DC Adapter Input Stage | USB-C Power Delivery Front-End |
|---|---|
Use Scenario: Rectifying 90–264 VAC mains input in compact wall adapters. IC Role / Device Role / Timing Role: Primary-side unidirectional current path enabling DC bus generation. Use Value: 200 V VRRM provides sufficient margin over 264 VAC peak (373 V), while 150 ns trr limits switching noise in space-constrained layouts. | Use Scenario: Input rectification in 20–100 W USB-C PD power modules. IC Role / Device Role / Timing Role: High-efficiency bridge leg component in active clamp or quasi-resonant topologies. Use Value: 1.3 V VFM reduces conduction loss at 1–2 A load currents; SMA package allows dense layout near controller ICs. |
| Industrial Sensor Power Supply | LED Driver Auxiliary Supply |
Use Scenario: Providing isolated 5–12 V bias for analog sensor signal conditioning circuits. IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback-derived auxiliary winding outputs. Use Value: Low IRM (5 µA) prevents loading of high-impedance feedback networks; 20 °C/W RJT simplifies thermal design on small PCBs. | Use Scenario: Generating gate drive or bias voltage in constant-current LED drivers. IC Role / Device Role / Timing Role: Output rectifier in self-oscillating or discrete controller-based flyback converters. Use Value: 30 A IFSM withstands startup surges from large output capacitors; cathode band ensures correct polarity during manual repair. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1D-13 | Same electrical specs and SMA package; lacks "B" suffix indicating standard tin plating vs. optional matte tin finish | No functional difference in most commercial applications; RS1DB-13 explicitly denotes RoHS-compliant matte tin plating | Select RS1DB-13 when lead-free compliance documentation and consistent solderability across reflow cycles are required |
| MUR120-AU | 200 V, 1 A, 50 ns trr - faster recovery but higher VFM (1.45 V); SMB package | Better suited for >200 kHz designs where Qrr reduction outweighs conduction loss penalty | Choose MUR120-AU only if board layout accommodates SMB and system efficiency gain justifies cost and voltage drop trade-off |
Compared with RS1D-13, RS1DB-13 guarantees documented RoHS-compliant matte tin plating; versus MUR120-AU, it trades 35 ns faster recovery for lower forward loss and SMA footprint compatibility in legacy designs.

FAQ
What is the maximum operating temperature for RS1DB-13?
The RS1DB-13 has an operating junction temperature range of –65 °C to +150 °C. Its rated average output current (1.0 A) applies at 120 °C terminal temperature, with derating required above that point per Figure 1 in the datasheet. Thermal design must account for 20 °C/W junction-to-terminal resistance.
Is RS1DB-13 compatible with lead-free reflow processes?
Yes - RS1DB-13 features matte tin lead-free plating compliant with RoHS Directive 2011/65/EU and is qualified for standard Pb-free reflow profiles (J-STD-020C Level 1). Its terminals meet MIL-STD-202 Method 208 solderability requirements without post-plating treatment.
How does RS1DB-13 differ from RS1D-13?
RS1DB-13 explicitly denotes the RoHS-compliant matte tin finish, whereas RS1D-13 may refer to legacy tin-lead or unspecified plating. Electrically and mechanically identical, RS1DB-13 ensures documented compliance and consistent wetting behavior in modern lead-free SMT lines.
Can RS1DB-13 replace a 1N4007 in high-frequency applications?
No - while both are 1 A rectifiers, the 1N4007 has ~2 µs recovery time and is unsuitable above ~1 kHz. RS1DB-13's 150 ns trr makes it viable up to ~100 kHz, but its 200 V VRRM is lower than 1N4007's 1000 V, limiting replacement to circuits with appropriate voltage derating.
