Product details
Overview
RS3M-13 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 datasheet, RS3M-13 pinout, RS3M-13 application, or RS3M-13 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (25 K/W), fast recovery performance under 60 Hz line-frequency switching, and SMB package compatibility with automated SMT assembly.
Technical Context
This device is a single-phase, silicon planar epitaxial fast recovery rectifier with glass-passivated junction. It operates under resistive or inductive loads at 60 Hz, requiring 20% current derating for capacitive loads.
Reverse recovery is characterized at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. Junction capacitance is 50 pF at 1.0 MHz and 4.0 V reverse bias, supporting high-frequency switching stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports 700 V RMS input systems with safety margin for transient overvoltage |
| IO @ TT=75°C | 3.0 A - continuous DC output current with 5.0 mm² copper pad heatsinking |
| VFM @ IF=3.0A | 1.3 V - low conduction loss enabling >89% efficiency in 24 V output SMPS |
| trr | 150 ns - limits switching losses in 20–100 kHz PFC and flyback stages |
| IFSM | 100 A - withstands cold-start inrush surges without degradation |
| RJT | 25 K/W - enables thermal design with minimal PCB copper area for cost-sensitive designs |
| IRM @ 125°C | 250 µA - ensures low leakage in high-temperature industrial environments |
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 | AC input connection point | Accepts incoming AC phase; must be routed with controlled impedance to minimize EMI during recovery |
| Cathode | DC output connection point | Feeds bulk capacitor; polarity marked by band; requires low-inductance trace to reduce voltage overshoot |

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, 3.0 A IO, 75 ns trr, TO-277 package | Limited to 400 VAC systems; faster recovery but lower voltage margin | Select when system peak line voltage ≤ 420 V and EMI reduction is critical |
| ON Semiconductor MUR3100E | 1000 V VRRM, 3.0 A IO, 200 ns trr, SMB package | Higher trr increases switching loss in 100 kHz designs; identical footprint | Prefer for legacy designs where 200 ns trr is already validated and thermal margin exists |
Compared with STTH3L06S and MUR3100E, RS3M-13 delivers optimal balance of 1000 V robustness and 150 ns speed in SMB form factor - making it ideal for new industrial power supplies targeting global 230 VAC/1000 V surge compliance without sacrificing thermal headroom.

FAQ
What is the maximum allowable junction temperature for RS3M-13?
The absolute maximum junction temperature is +150°C, with continuous operation rated up to +125°C junction under specified thermal conditions. Derating begins at terminal temperatures above 75°C, as shown in Figure 1 of the datasheet - requiring minimum 5.0 mm² copper pad area for full 3.0 A current handling.
Can RS3M-13 replace RS3J-13 in an existing design?
Yes, RS3M-13 is a direct upgrade from RS3J-13 (600 V) with identical SMB package, pinout, and thermal characteristics. The higher 1000 V VRRM improves surge immunity without layout change, though forward voltage remains 1.3 V at 3.0 A - no revalidation needed for thermal or footprint constraints.
Is RS3M-13 suitable for use in a capacitive-input filter?
No - the datasheet explicitly requires 20% derating of average forward current when used with capacitive loads. For such applications, IO must be limited to 2.4 A, and additional snubbing or inrush limiting is recommended to avoid exceeding IFSM during startup.
Does RS3M-13 meet RoHS and REACH requirements?
Yes, RS3M-13 is RoHS-compliant (lead-free termination, homogeneous material restrictions met) and REACH-conformant per Diodes Incorporated's published declarations. Halogen-free status is confirmed per IEC 61249-2-21, with bromine and chlorine content below 900 ppm each.
