Product details
Overview
RS3M-13-F from Diodes Incorporated is a 1000 V, 3.0 A surface-mount fast recovery rectifier in SMB package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge capability - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the RS3M-13-F datasheet, RS3M-13-F pinout, RS3M-13-F application, or RS3M-13-F equivalent, key selection criteria include peak reverse voltage rating (1000 V), thermal resistance (25 K/W), junction-to-terminal mounting requirements, and fast recovery performance under 60 Hz half-wave resistive load conditions.
Technical Context
This device is a single-phase, silicon planar epitaxial fast recovery rectifier with glass-passivated die construction. It delivers low forward voltage drop (1.3 V @ 3.0 A) and high surge robustness (100 A, 8.3 ms sine wave), optimized for high-efficiency switching power conversion stages where rapid turn-off minimizes switching losses.
Reverse recovery is characterized at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, yielding trr = 150 ns. Junction capacitance is 50 pF at 4.0 V reverse bias and 1.0 MHz, supporting stable high-frequency operation in PFC and flyback topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage the device blocks without breakdown in normal operation |
| IO @ TT=75°C | 3.0 A - average forward current derated to terminal temperature of 75°C, usable in continuous conduction mode |
| VFM @ IF=3.0A | 1.3 V - forward voltage drop determining conduction loss and thermal rise in rectifier leg |
| trr | 150 ns - reverse recovery time defining minimum dead-time requirement and EMI generation in hard-switched converters |
| IFSM | 100 A - peak surge current tolerance enabling robustness against line transients and inrush events |
| RJT | 25 K/W - thermal resistance from junction to terminal, requiring ≥5.0 mm² copper pad for rated current handling |
| IRM @ 125°C | 250 µA - leakage current at elevated temperature, critical for standby power and high-temperature reliability |
Pinout & Package
SMB (DO-214AA) surface-mount plastic package with cathode band marking; terminals are solder-plated and compliant with MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for AC or positive half-cycle | Connected to AC source or transformer secondary; carries full load current during forward conduction |
| Cathode | Output for DC bus or filter capacitor | Delivers rectified output; polarity marked by band; must interface with low-inductance DC path |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 150 ns enables use in 100 kHz+ SMPS without excessive switching loss or ringing |
| Glass-passivated die | Enhances humidity resistance and long-term reliability in industrial ambient conditions |
| UL 94V-0 plastic case | Meets flammability safety requirements for enclosed power equipment and lighting systems |
| Low VF at rated current | 1.3 V drop reduces conduction loss by ~15% vs. standard 1N54xx series at 3 A |
Applications
| Industrial AC/DC Power Supply | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase input stage of 50–100 W open-frame power supply operating from 85–265 VAC. IC Role / Device Role / Timing Role: Fast recovery rectifier in bridge or single-diode configuration for primary-side AC-to-DC conversion. Use Value: 150 ns trr minimizes reverse recovery charge (Qrr), reducing MOSFET turn-on loss and EMI in adjacent switching devices. | Use Scenario: Off-line LED driver with passive PFC and constant-current output for streetlight modules. IC Role / Device Role / Timing Role: Input rectifier handling 3.0 A average current with high peak surges during cold-start. Use Value: 100 A IFSM withstands inrush into large bulk capacitors without degradation over 10,000 cycles. |
| UPS Battery Charger Input Stage | Motor Drive Auxiliary Power Supply |
Use Scenario: Dual-input rectifier in online UPS charger accepting both utility and generator sources. IC Role / Device Role / Timing Role: High-voltage (1000 V) blocking diode ensuring reverse isolation during battery discharge mode. Use Value: 1000 V VRRM provides 2× margin over 400 VDC bus, preventing failure during regenerative voltage spikes. | Use Scenario: Auxiliary 24 V supply powering gate drivers and logic in 3-phase inverter control board. IC Role / Device Role / Timing Role: Secondary-side fast rectifier converting transformer output to regulated DC. Use Value: 25 K/W RJT allows direct PCB copper pad heatsinking-no external heatsink needed for ≤3 A continuous load. |
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, 120 ns trr, TO-277 package | Limited to ≤600 V AC lines; lower voltage margin but faster recovery | Select when system input is ≤277 VAC and EMI reduction is prioritized over surge robustness |
| ES3M-E3/57T | 1000 V VRRM, 250 ns trr, same SMB package | Slower recovery increases Qrr by ~65%, raising switching loss in high-frequency designs | Acceptable for 50–60 kHz flyback supplies where thermal margin exceeds 15°C |
Compared with RS3M-13-F, STTH3L06S trades voltage headroom for speed in lower-input systems, while ES3M-E3/57T matches voltage rating but sacrifices recovery performance-making RS3M-13-F optimal for universal-input, high-surge, medium-frequency industrial rectification.

FAQ
What is the maximum allowable junction temperature for RS3M-13-F?
The absolute maximum junction temperature is +150°C, with storage temperature range matching at –65°C to +150°C. Operation above 125°C requires derating IO below 3.0 A per Figure 1, and thermal design must maintain TJ ≤ 150°C using the specified 5.0 mm² copper pad heatsink.
Can RS3M-13-F replace a standard 1N5408 in a 100 W power supply?
Yes, but only if the circuit operates below 1000 V peak reverse stress and benefits from faster recovery. RS3M-13-F offers 150 ns trr versus 2000 ns for 1N5408, reducing switching loss and EMI-but its SMB package has higher thermal resistance than DO-201AD, so PCB copper area must be verified for thermal compliance.
Is RS3M-13-F suitable for use in a capacitive-input filter?
No-per datasheet guidance, current must be derated by 20% for capacitive loads due to high peak currents. For such applications, use a higher-current-rated part like RS5M or implement inrush limiting; RS3M-13-F is optimized for resistive/inductive loads per JEDEC test conditions.
Does RS3M-13-F have a lead-free and RoHS-compliant finish?
Yes, RS3M-13-F is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "-F" suffix explicitly denotes lead-free, halogen-free, and green-compliant construction per Diodes Incorporated's material declarations.
