Product details
Overview
RS2BA-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode in SMA package, rated for 100 V peak repetitive reverse voltage (VRRM), 1.5 A average forward current (IO), and 50 A non-repetitive surge current (IFSM). It features 150 ns reverse recovery time (trr), 1.3 V forward voltage at 1.5 A (VFM), and is RoHS-compliant with lead-free matte tin plating - used in AC/DC front-end rectification and DC-DC converter flyback snubbers.
For engineers reviewing the RS2BA-13-F datasheet, RS2BA-13-F pinout, RS2BA-13-F application, or RS2BA-13-F equivalent, key selection criteria include its fast recovery performance (150 ns trr), thermal resistance (20 °C/W junction-to-terminal), 100 V blocking capability, and suitability for automated SMT assembly in power supplies and industrial converters.
Technical Context
This device operates as a unidirectional silicon PN junction rectifier optimized for high-frequency switching applications. Its glass-passivated die construction ensures stable reverse leakage (<5 µA at 25°C) and robust surge tolerance (50 A IFSM), while the fast recovery time enables efficient operation in 50–100 kHz SMPS topologies.
The SMA package provides low thermal resistance (RθJT = 20 °C/W) when mounted on 5.0 mm² copper pads, supporting continuous 1.5 A conduction up to 120°C terminal temperature. Polarity is marked by a cathode band, and moisture sensitivity is rated Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input or flyback clamp voltage rating. |
| IO | 1.5 A - Average forward current at TT = 120°C; sets continuous power handling in rectifier bridges or output stages. |
| trr | 150 ns - Reverse recovery time under IF = 0.5 A / IR = 1.0 A conditions; enables efficient operation up to ~100 kHz switching. |
| VFM | 1.3 V @ 1.5 A - Forward voltage drop; determines conduction loss (1.95 W max at full load) and thermal design margin. |
| IFSM | 50 A - Non-repetitive surge rating (8.3 ms half-sine); withstands inrush and fault currents in offline supplies. |
| RθJT | 20 °C/W - Junction-to-terminal thermal resistance; guides PCB copper pad sizing for thermal management. |
Pinout & Package
RS2BA-13-F uses the SMA (DO-214AC) surface-mount package: molded plastic body (UL 94V-0), cathode-banded polarity, and matte tin-plated terminals solderable per MIL-STD-202 Method 208. Weight is approximately 0.065 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node in flyback). |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to output rail or snubber network; must sustain full VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 150 ns - Reduces switching losses and EMI in high-frequency rectification circuits. |
| Glass passivated die | Enhances long-term reliability and stability of reverse leakage under thermal cycling and humidity stress. |
| Surge rating | 50 A IFSM - Supports robust inrush handling without degradation in AC-DC adapters and motor drives. |
| Lead-free & halogen-free | RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb - meets automotive and industrial environmental mandates. |
Applications
| AC-DC Adapter Input Rectification | Flyback Converter Output Rectification |
|---|---|
Use Scenario: Converts 90–264 VAC mains to DC bus in compact wall adapters and USB-PD power supplies. IC Role / Device Role / Timing Role: Primary-side bridge rectifier conducting 50/60 Hz line frequency; handles 1.5 A average output current. Use Value: Low VFM (1.3 V) minimizes conduction loss; fast trr avoids excessive heating during zero-crossing transitions. | Use Scenario: Rectifies high-frequency (65–100 kHz) transformer output in isolated DC-DC converters for telecom and industrial control. IC Role / Device Role / Timing Role: Secondary-side synchronous or quasi-synchronous rectifier; blocks reverse voltage during transformer reset phase. Use Value: 150 ns trr reduces reverse recovery loss and improves efficiency over standard recovery diodes. |
| DC Link Snubber Network | Industrial Motor Drive Freewheeling |
Use Scenario: Absorbs voltage spikes across MOSFETs/IGBTs in PWM inverters and SMPS power stages. IC Role / Device Role / Timing Role: Fast freewheeling path during switching transitions; clamps inductive kickback within 100 V limit. Use Value: 100 V VRRM and 50 A IFSM ensure reliable transient suppression without avalanche stress. | Use Scenario: Provides return path for inductive current during H-bridge turn-off in 24–48 V BLDC motor controllers. IC Role / Device Role / Timing Role: Freewheeling diode across motor winding; conducts 1.5 A continuous current during PWM off-time. Use Value: SMA package enables dense layout; 20 °C/W RθJT supports thermal stability under sustained 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 |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1 A IO, 75 ns trr - higher voltage rating but lower current and faster recovery. | Suitable for higher-voltage flyback outputs (>400 V), not for 100 V input rectification. | Select only if system requires >100 V blocking and can accept reduced current rating. |
| ON Semiconductor MUR110 | 100 V VRRM, 1 A IO, 75 ns trr - same voltage rating but lower current and faster recovery than RS2BA-13-F. | Used in low-power auxiliary supplies; insufficient for 1.5 A continuous loads. | Choose only for space-constrained designs where 1 A rating suffices and ultra-fast recovery is prioritized. |
Compared with STTH1L06S and MUR110, RS2BA-13-F uniquely balances 100 V blocking, 1.5 A current capacity, and 150 ns recovery - making it optimal for mainstream 12–24 V output, 1.5 A AC-DC and isolated DC-DC converters where thermal margin and surge robustness are critical.

FAQ
What is the maximum operating temperature for RS2BA-13-F?
The RS2BA-13-F has an operating junction temperature range of –65°C to +150°C and is rated for 1.5 A average forward current at a terminal temperature (TT) of 120°C. Derating begins above that point per Figure 1 in DS15004, with full current supported only when thermal design maintains TT ≤ 120°C.
Is RS2BA-13-F qualified for automotive applications?
RS2BA-13-F is not AEC-Q101 qualified out-of-the-box. Diodes offers automotive-grade variants (e.g., RS2BAQ-13-F) with PPAP documentation, IATF 16949 manufacturing, and AEC-Q101 stress testing - contact Diodes or Aetrix for qualified alternatives if automotive use is required.
How does the SMA package affect PCB layout and thermal performance?
The SMA (DO-214AC) package requires specific pad dimensions (C = 4.00 mm, G = 1.50 mm, X = 2.50 mm per DS15004) and benefits from ≥5.0 mm² copper pads to achieve the specified 20 °C/W junction-to-terminal thermal resistance. Insufficient copper area increases thermal impedance and risks exceeding TJ limits under load.
Can RS2BA-13-F replace a standard recovery rectifier like 1N4007?
No - RS2BA-13-F is a fast recovery diode (150 ns trr), while 1N4007 is a general-purpose rectifier with ~30 µs recovery. Substituting RS2BA-13-F into 50/60 Hz linear supply designs offers no benefit and risks over-specification; it is intended for high-frequency switching applications where fast recovery reduces loss and EMI.
