Product details
Overview
RS2AA-13-F from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier in SMA package, rated for 50V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A (VFM), and 150ns reverse recovery time (trr). It features glass passivated die construction, 50A non-repetitive surge capability, and RoHS-compliant lead-free plating - deployed in AC/DC front-end rectification for compact power supplies and DC motor flyback protection.
For engineers reviewing the RS2AA-13-F datasheet, RS2AA-13-F pinout, RS2AA-13-F application, or RS2AA-13-F equivalent, key selection criteria include VRRM derating under capacitive loads, thermal resistance (RθJT = 20°C/W) with PCB copper pad heatsinking, trr-driven switching loss trade-offs in 50–100kHz SMPS, and SMA package solderability per MIL-STD-202 Method 208.
Technical Context
This device operates as a unidirectional silicon PN junction rectifier optimized for high-efficiency, medium-frequency switching applications. Its fast recovery (trr = 150ns) minimizes reverse conduction losses during commutation, while glass passivation ensures stable leakage performance across -65°C to +150°C operating range.
The SMA package enables automated placement and reflow compatibility, with terminal-to-junction thermal resistance of 20°C/W when mounted on 5.0 mm² copper pads. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum allowable repetitive reverse voltage before breakdown; defines safe operating margin in 24V AC input rectifiers. |
| IO @ TT=120°C | 1.5 A - Continuous average forward current rating at terminal temperature of 120°C; requires thermal management via PCB copper area. |
| VFM @ IF=1.5A | 1.3 V - Forward voltage drop at rated current; determines conduction loss (1.95W max at 1.5A) and thermal load. |
| trr | 150 ns - Reverse recovery time under IF=0.5A/IR=1.0A/Irr=0.25A test conditions; critical for EMI and efficiency in 50–200kHz converters. |
| IFSM (8.3ms) | 50 A - Non-repetitive surge current rating; supports inrush current handling in offline power supplies without failure. |
| RθJT | 20 °C/W - Junction-to-terminal thermal resistance; used with PCB copper pad area to calculate junction temperature rise under load. |
| IRM @ 25°C | 5.0 µA - Peak reverse leakage at rated VRRM and 25°C; low leakage preserves efficiency in standby modes. |
Pinout & Package
Package: SMA (Surface Mount Axial), molded plastic body with UL 94V-0 flammability rating, cathode band polarity marking, and matte tin-plated terminals. Weight: ~0.065 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or switch node; must withstand full surge current and reverse voltage stress. |
| Cathode | Forward current exit point | Connected to output capacitor or load return; cathode band identifies this terminal for correct PCB layout orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures stable IR leakage and long-term reliability under humidity and thermal cycling, meeting industrial-grade lifetime requirements. |
| Fast recovery (150ns) | Reduces reverse recovery charge (Qrr) and associated switching losses in medium-frequency SMPS, improving overall efficiency by ~0.5–1.2% vs standard rectifiers. |
| 50A surge rating | Withstands cold-start inrush and transient overloads without degradation, eliminating need for external fusing in many 12–24V DC systems. |
| SMA package with J-STD-020 Level 1 MSL | Enables standard reflow assembly without baking; compatible with high-volume SMT lines and eliminates moisture-related popcorning risk. |
Applications
| AC/DC Adapter Rectification | DC Motor Flyback Protection |
|---|---|
Use Scenario: 24V AC input rectified to 32V DC in wall-mounted power adapters for IoT gateways. IC Role / Device Role / Timing Role: Primary-side unidirectional current path; conducts during positive half-cycle, blocks reverse voltage during negative half-cycle. Use Value: 150ns trr limits switching loss and EMI generation at 65kHz operation; 1.3V VFM keeps conduction loss below 2W at full load. | Use Scenario: Freewheeling diode across brushed DC motor in automotive seat adjuster module. IC Role / Device Role / Timing Role: Provides low-impedance path for inductive kickback current when MOSFET switch turns off. Use Value: 50A IFSM handles 3× stall current surges; glass passivation prevents leakage-induced false triggering in humid cabin environments. |
| Industrial Sensor Power Supply | LED Driver Input Stage |
Use Scenario: Compact 12V DC power rail derived from 24VAC field wiring in factory automation sensors. IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator; operates continuously at 0.8A average load. Use Value: RθJT = 20°C/W allows safe operation with minimal copper area (5 mm²); RoHS/Green compliance meets EU industrial directives. | Use Scenario: Input rectifier in constant-current LED driver for commercial signage (120VAC input). IC Role / Device Role / Timing Role: Converts AC line to pulsating DC prior to bulk capacitance and buck regulation. Use Value: 50V VRRM provides 2× safety margin over 24V peak rectified voltage; 5.0µA IRM ensures low standby power consumption. |
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 | Same SMA package; 600V VRRM, 1.7V VFM @ 1A, 50ns trr - higher voltage rating but higher forward loss. | Targeted at 100–400V AC inputs; unsuitable for 24V systems due to excessive VFM penalty at low voltage. | Select only if system requires >100V reverse blocking; avoid for 24–48V applications where conduction loss dominates. |
| MBR150 | SMA package; Schottky structure, 50V VRRM, 0.55V VFM @ 1.5A, no reverse recovery - zero trr but higher IRM (100µA @ 25°C). | Better efficiency at light loads and high frequency; limited to ≤125°C operation and sensitive to thermal runaway under sustained overload. | Prefer for high-frequency, low-voltage (<24V), thermally constrained designs; avoid in automotive under-hood or industrial high-temp environments. |
Compared with STTH1L06S and MBR150, RS2AA-13-F delivers optimal balance of low VFM, controlled trr, and robust surge tolerance specifically for 24–48V industrial and adapter applications - offering superior thermal stability and lower leakage than Schottky alternatives while avoiding unnecessary voltage overhead of 600V+ rectifiers.

FAQ
What is the maximum operating temperature for RS2AA-13-F?
The RS2AA-13-F has an operating and storage temperature range of -65°C to +150°C. Its thermal resistance (RθJT = 20°C/W) means junction temperature rises 20°C per watt dissipated above terminal temperature - so at 1.5A and 1.3V VFM (1.95W), terminal temperature must stay below 125°C to keep TJ ≤ 150°C.
Is RS2AA-13-F suitable for automotive applications?
RS2AA-13-F is not AEC-Q101 qualified out-of-box. While it meets RoHS/Green standards and operates up to +150°C, Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - contact Diodes directly for qualified variants like RS2AAQ-13-F.
How does RS2AA-13-F differ from RS2A-13-F?
RS2AA-13-F uses the SMA package with "AA" suffix indicating cathode-band marking and RoHS/Green compliance; RS2A-13-F is the SMB-package variant (larger footprint, 0.09g weight, different pad layout). Both share identical electrical specs (50V VRRM, 1.3V VFM, 150ns trr), but SMA offers tighter board space usage and lower thermal mass.
Can RS2AA-13-F replace a standard 1N4001 in a 24V circuit?
Yes - RS2AA-13-F exceeds 1N4001's 50V PIV rating and matches its 1A average current, but offers faster recovery (150ns vs ~30µs), lower VFM (1.3V vs ~1.1V at 1A), and surface-mount compatibility. However, its SMA footprint requires PCB redesign; through-hole 1N4001 cannot be drop-in replaced without adapter.
