Product details
Overview
RS2AA M2G from Taiwan Semiconductor is a 1.5A, 50V fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C - used in DC-DC converters and snubber circuits.
For engineers reviewing the RS2AA M2G datasheet, RS2AA M2G pinout, RS2AA M2G application, or RS2AA M2G equivalent, key selection criteria 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 M2G 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 support efficiency in compact DC-DC converters and snubbers where rapid turn-off and conduction loss minimization are critical.
Thermally, it sustains operation from –55°C to +175°C junction temperature, with RθJL = 18 °C/W enabling effective heat transfer to PCB copper. The DO-214AC (SMA) package provides JESD201 Class 2 whisker resistance and matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse voltage; defines safe blocking capability in 50 V-rated power rails |
| IF | 1.5 A - continuous forward current rating; determines usable output current in rectification paths |
| trr | 150 ns - reverse recovery time; enables stable operation up to ~1 MHz switching frequencies |
| VF (max) | 1.3 V @ 1.5 A - forward voltage drop; directly impacts conduction loss and thermal load at rated current |
| IR (max) | 5 µA @ 25°C - reverse leakage current; ensures minimal standby power loss in high-impedance circuits |
| RθJL | 18 °C/W - junction-to-lead thermal resistance; supports reliable thermal coupling to PCB copper pour or heatsink pad |
| MSL | Level 1 (J-STD-020) - no floor life limitation; suitable for standard SMT reflow without dry pack or baking |
Pinout & Package

Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters operating at 100–500 kHz. IC Role / Device Role / Timing Role: Fast-recovery rectifier converting transformer secondary AC to regulated DC output. Use Value: 150 ns trr and 1.3 V VF minimize switching loss and conduction loss, improving overall converter efficiency by ~1.2% vs. standard recovery diodes. | Use Scenario: Clamp voltage spikes across MOSFETs or IGBTs in motor drives and power supplies. IC Role / Device Role / Timing Role: Passive clamp diode absorbing inductive energy during switch turn-off. Use Value: Low trr ensures rapid turn-on to capture transient energy before voltage overshoot exceeds safe limits. |
| Lighting Application | Switching Mode Inverter |
Use Scenario: Input rectification and auxiliary supply in LED drivers with universal AC input (85–265 VAC). IC Role / Device Role / Timing Role: Bridge or single-phase rectifier feeding PFC or buck/boost stages. Use Value: 175°C max junction temperature and robust 50 A IFSM enable reliable operation under surge conditions common in lighting surges. | Use Scenario: Output rectification in high-frequency inverters for HVAC fans or small appliances. IC Role / Device Role / Timing Role: High-speed freewheeling path for inductive loads during PWM dead-time intervals. Use Value: Fast recovery and low VF reduce heat buildup in thermally constrained inverter PCB layouts. |
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 IF (1.5 A), VRRM = 600 V, trr = 75 ns, VF = 1.15 V (typ), DO-214AC package | Higher voltage rating and faster recovery suit 400–600 V systems; not drop-in for 50 V designs due to over-spec'd VRRM | Select when higher blocking margin or lower VF/trr required; verify layout compatibility with identical SMA footprint |
| ES1B (ON Semiconductor) | IF = 1 A, VRRM = 100 V, trr = 35 ns, VF = 1.7 V (max), same DO-214AC package | Lower current rating limits use to ≤1 A loads; faster trr benefits ultra-high-frequency snubbers but higher VF increases loss | Choose for space-constrained 100 V snubbers needing sub-50 ns recovery; derate current or parallel devices for 1.5 A needs |
Compared with STTH1L06U and ES1B, the RS2AA M2G offers optimal balance of 50 V rating, 1.5 A capacity, and 150 ns trr for cost-sensitive, thermally moderate 50 V DC-DC and lighting applications - avoiding overdesign while ensuring manufacturability and compliance.

FAQ
What is the maximum junction temperature rating for RS2AA M2G?
The RS2AA M2G has a maximum junction temperature (TJ MAX) of +175°C, allowing reliable operation in thermally demanding environments such as enclosed LED drivers or high-density DC-DC modules. This rating is validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version I2304 and supports extended lifetime under continuous 1.5 A forward conduction at elevated ambient temperatures.
Is RS2AA M2G compatible with lead-free reflow soldering processes?
Yes, RS2AA M2G features matte tin-plated leads qualified to J-STD-002 for solderability and is rated for lead-free reflow profiles including JEDEC J-STD-020-compliant peak temperatures up to 260°C. Its DO-214AC (SMA) package and Level 1 moisture sensitivity eliminate pre-bake requirements, simplifying integration into standard SMT lines.
What does the "M2G" suffix indicate in RS2AA M2G?
The "M2G" suffix in RS2AA M2G denotes Taiwan Semiconductor's internal packaging and environmental coding: "M" indicates tape-and-reel packaging (7,500 pcs/reel), "2" specifies green (halogen-free) molding compound, and "G" confirms RoHS compliance. This matches ordering code conventions defined in the RS2AA–RS2MA datasheet Version I2304.
How does RS2AA M2G compare to standard recovery rectifiers in switching applications?
RS2AA M2G delivers 150 ns reverse recovery time versus >1 µs for standard recovery diodes, reducing switching losses and EMI in DC-DC converters above 50 kHz. Its 1.3 V VF at 1.5 A also lowers conduction loss compared to legacy 1N400x series, making RS2AA M2G suitable for modern high-efficiency power supplies where thermal and electrical performance are critical.
Can RS2AA M2G be used in place of RS2BA or RS2DA in a design?
No - RS2AA M2G is rated for 50 V VRRM, whereas RS2BA and RS2DA are rated for 100 V and 200 V respectively. Substituting RS2AA M2G in circuits with higher reverse voltage stress risks premature breakdown. Always match VRRM to the peak reverse voltage seen in the application; RS2AA M2G is only appropriate for ≤50 V blocking requirements.
