Product details
Overview
RS2AA R3G from Taiwan Semiconductor is a 1.5A, 50V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 50 A peak surge current - used in DC-DC converters and snubber circuits for high-efficiency switching power supplies.
For engineers reviewing the RS2AA R3G datasheet, RS2AA R3G pinout, RS2AA R3G application, or RS2AA R3G equivalent, key selection factors include repetitive peak reverse voltage (50 V), thermal resistance (18 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMA package compatibility with automated placement.
Technical Context
The RS2AA R3G is a single-die, glass-passivated fast recovery rectifier optimized for high-frequency switching applications. Its 150 ns trr and low 1.3 V VF at rated current support efficiency in compact DC-DC converters and inverters.
Thermal performance is defined by RθJL = 18 °C/W and RθJA = 55 °C/W, enabling reliable operation up to 175 °C junction temperature. Polarity is marked by cathode band per JEDEC DO-214AC mechanical standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse voltage before breakdown; sets safe operating limit in 50 V-rated DC bus or clamp circuits |
| IF | 1.5 A continuous - average forward current rating defining steady-state power handling capability |
| trr | 150 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in SMPS |
| VF | ≤1.3 V at IF = 1.5 A, TJ = 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| IFSM | 50 A - non-repetitive surge current rating for 8.3 ms half-sine wave; supports inrush and fault transient tolerance |
| TJ max | 175°C - maximum junction temperature allowing operation in high-ambient industrial environments |
| RθJL | 18 °C/W - junction-to-lead thermal resistance; critical for heatsinking via PCB copper pour or lead-frame thermal path |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case meeting UL 94V-0; matte tin-plated leads, JESD 201 Class 2 whisker compliant; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential rail (e.g., output capacitor positive); defines direction of unidirectional conduction |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in reflow-soldered assemblies without hermetic sealing |
| Fast recovery (150 ns) | Reduces switching losses and EMI generation in high-frequency (>500 kHz) topologies like LLC resonant converters |
| J-STD-020 Level 1 moisture sensitivity | Enables direct use from reel without baking; eliminates production delay and moisture-related popcorning risk |
| RoHS and halogen-free compliance | Meets global environmental regulations for consumer, industrial, and automotive supply chains requiring substance restrictions |
| DO-214AC (SMA) footprint | Standardized 4.06 mm × 2.29 mm body with 2.50 mm lead spacing; compatible with legacy SMA land patterns and pick-and-place tooling |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Output rectification in isolated flyback or forward converters operating at 100–500 kHz. IC Role / Device Role / Timing Role: Unidirectional current path during transformer secondary conduction phase; blocks reverse voltage during primary switch on-time. Use Value: 150 ns trr minimizes reverse recovery charge loss, improving efficiency over slower general-purpose rectifiers. | Use Scenario: Voltage clamping across MOSFETs or IGBTs in hard-switched inverters. IC Role / Device Role / Timing Role: Fast turn-off diode absorbing inductive energy spike during switching transitions. Use Value: Low VF (≤1.3 V) and fast trr reduce snubber power dissipation and improve system thermal margin. |
| Lighting Driver | Switching Inverter |
Use Scenario: Secondary-side rectification in LED driver IC-based constant-current supplies. IC Role / Device Role / Timing Role: Converts high-frequency AC from transformer secondary into regulated DC for LED string biasing. Use Value: 1.5 A IF rating supports common 1–2 A LED loads; DO-214AC package fits compact driver PCB layouts. | Use Scenario: Freewheeling path in half-bridge motor drive inverters for HVAC or appliance control. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive load current when upper switch is off. Use Value: 50 A IFSM withstands motor startup surges; 175°C TJ max ensures stability under sustained load conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U (STMicroelectronics) | Same 1.5 A / 600 V rating but higher VRRM; trr = 75 ns, VF = 1.15 V typical | Better suited for 600 V bus systems; not rated for ≤50 V low-voltage designs where RS2AA R3G's tighter VRRM margin improves safety factor | Select RS2AA R3G when VRRM = 50 V is required for cost-sensitive 24–48 V systems with minimal voltage overhead |
| MBR1550CT (ON Semiconductor) | 15 A dual common-cathode Schottky; VF ≈ 0.75 V but no reverse blocking above ~50 V | Not suitable for reverse-biased applications; only usable in low-VR freewheeling roles where reverse leakage must be near-zero | Choose RS2AA R3G instead when true 50 V reverse blocking and fast recovery (not just low VF) are mandatory |
Compared with STTH1L06U and MBR1550CT, RS2AA R3G offers optimal balance of low-cost 50 V rating, validated 150 ns recovery, and robust surge capability - making it preferred for cost-constrained, medium-frequency DC-DC and snubber use cases where precise voltage grading matters.

FAQ
What is the maximum junction temperature rating for RS2AA R3G?
The RS2AA R3G has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2304. This allows RS2AA R3G to operate reliably in high-ambient environments such as enclosed industrial power supplies or thermally constrained LED drivers without derating below full 1.5 A current.
Is RS2AA R3G suitable for automated SMT assembly?
Yes, RS2AA R3G is explicitly designed for automated placement: it meets J-STD-020 moisture sensitivity Level 1, uses matte tin-plated leads solderable per J-STD-002, and features a standardized DO-214AC (SMA) outline compatible with industry-standard pick-and-place feeders and reflow profiles - all confirmed in the mechanical data section of the RS2AA R3G datasheet.
What does the 'R3G' suffix indicate in RS2AA R3G?
The 'R3G' suffix in RS2AA R3G denotes Taiwan Semiconductor's internal packaging and environmental code: 'R3' specifies tape-and-reel packaging (7,500 units per reel), and 'G' indicates green (halogen-free) molding compound - both defined in the Ordering Information section of the RS2AA R3G datasheet Version I2304.
How does RS2AA R3G compare to general-purpose rectifiers like 1N4007?
RS2AA R3G delivers significantly faster switching (150 ns trr vs. >2 µs for 1N4007), lower forward voltage (≤1.3 V vs. ~1.7 V), and higher surge capability (50 A vs. 30 A), making RS2AA R3G appropriate for high-frequency SMPS where 1N4007 would cause excessive loss and overheating - confirmed by electrical specifications tables in the RS2AA R3G datasheet.
Does RS2AA R3G have RoHS and halogen-free certification?
Yes, RS2AA R3G is certified RoHS compliant and halogen-free, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet Version I2304. The 'G' in the part number RS2AA R3G explicitly references green (halogen-free) compound, and compliance is verified per JEDEC J-STD-609 and IPC-1752 standards cited in TSC's product documentation.
