Product details
Overview
RS2GA R3G from Taiwan Semiconductor is a 1.5A, 400V 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 5 µA max reverse leakage at 25°C. It serves as primary output rectifier in DC-DC converters and snubber diodes in switching inverters.
For engineers reviewing the RS2GA R3G datasheet, RS2GA R3G pinout, RS2GA R3G application, or RS2GA R3G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (18 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and DO-214AC mechanical compatibility with automated placement.
Technical Context
This discrete silicon rectifier uses glass-passivated PN junction technology optimized for high-frequency switching operation. Its 150 ns trr and low 50 pF junction capacitance enable efficient performance in 50–500 kHz SMPS topologies while maintaining robust surge capability (50 A IFSM).
The device operates across –55°C to +175°C junction temperature range with 18 °C/W junction-to-lead thermal resistance, supporting thermally constrained PCB layouts. Cathode band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits |
| IF | 1.5 A continuous - Average forward current rating at TA = 75°C; sets conduction loss and heatsink requirements |
| trr | 150 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; critical for minimizing switching losses in high-frequency converters |
| VF | ≤1.3 V @ 1.5 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design |
| IR | ≤5 µA @ 400 V, 25°C - Low leakage preserves efficiency in high-impedance bias networks and snubbers |
| RθJL | 18 °C/W - Junction-to-lead thermal resistance enables direct thermal path to copper pour or heatsink pad |
| MSL | Level 1 (J-STD-020) - No floor life limitation; suitable for standard SMT reflow without dry pack handling |

Applications
| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/24 V offline flyback or forward converters delivering up to 18 W. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; handles 1.5 A average forward current and 50 A surge transients. Use Value: 150 ns trr minimizes switching loss overlap; 1.3 V VF limits conduction loss to ≤1.95 W at full load, easing thermal management. | Use Scenario: Clamp diode in RCD snubber across MOSFET drain-source in 65–130 kHz half-bridge inverters for LED drivers. IC Role / Device Role / Timing Role: Fast turn-on/turn-off path for transient energy dissipation; blocks 400 V DC bus during normal operation. Use Value: Low 5 µA IR prevents DC leakage into snubber capacitor; 50 pF CJ avoids resonance with snubber inductance at switching frequencies. |
| Switching Inverter Freewheeling | Lighting Ballast Rectification |
Use Scenario: Freewheeling path for inductive loads in 20–50 kHz resonant inverters used in induction heating control modules. IC Role / Device Role / Timing Role: Provides low-loss return path during MOSFET off-time; withstands repetitive 400 V reverse stress with minimal recovery tail. Use Value: 175°C TJ max rating allows operation in sealed enclosures; 18 °C/W RθJL supports direct thermal coupling to metal-core PCB. | Use Scenario: Input bridge rectifier in 100–200 W electronic ballasts for HID lamps, operating continuously at 75°C ambient. IC Role / Device Role / Timing Role: Converts 230 VAC line to pulsating DC; endures 50 A IFSM surges during cold-start inrush. Use Value: Glass passivation ensures stable VF and IR over 10-year lifetime; UL 94V-0 molding compound resists arc tracking in high-voltage lamp compartments. |
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 75 ns trr; higher VF (1.7 V) at 1.5 A; TO-277 package | Lower trr suits >500 kHz designs; TO-277 requires different footprint and thermal pad layout | Select when faster recovery outweighs VF penalty and board redesign is acceptable |
| ES1J (ON Semiconductor) | 1 A / 600 V; 35 ns trr; DO-214AA (SMB) package; VF = 1.7 V @ 1 A | Lower current rating limits to ≤12 W outputs; SMB footprint incompatible with SMA land pattern | Use only in space-constrained, lower-power (<10 W) designs where ultra-fast recovery is mandatory |
Compared with STTH1L06U and ES1J, RS2GA R3G offers optimal balance of 400 V blocking, 1.5 A current, 150 ns trr, and DO-214AC compatibility-making it ideal for cost-sensitive, thermally moderate 15–25 W industrial DC-DC and lighting applications without requiring layout changes.

FAQ
What is the maximum junction temperature rating for RS2GA R3G?
The RS2GA R3G has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official TSC datasheet Version I2304. This allows operation in sealed enclosures or high-ambient environments common in industrial motor drives and LED lighting housings. Derating curves confirm usable current down to –55°C storage, making RS2GA R3G suitable for wide-temperature-range deployments.
Is RS2GA R3G pin-compatible with other devices in the RS2xx family?
Yes, all RS2xx devices-including RS2GA R3G-share identical DO-214AC (SMA) package dimensions, anode/cathode pinout, and polarity marking (cathode band). Voltage variants (RS2AA to RS2MA) are mechanically interchangeable; only VRRM and trr differ. RS2GA R3G may be substituted for RS2DA or RS2JA on the same footprint if voltage and recovery time requirements align.
Does RS2GA R3G meet lead-free soldering requirements?
Yes, RS2GA R3G features matte tin-plated leads qualified per J-STD-002 for solderability and complies with RoHS Directive 2011/65/EU. Its DO-214AC package withstands standard Pb-free reflow profiles (peak 260°C, 10 sec), and its Level 1 moisture sensitivity eliminates pre-bake requirements-enabling direct placement in high-throughput SMT lines.
What is the reverse recovery time (trr) test condition for RS2GA R3G?
The reverse recovery time for RS2GA R3G is specified as ≤150 ns under conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, measured per JEDEC JESD24-11. This test setup reflects real-world commutation in flyback and forward converters. The value appears in the Electrical Specifications table on page 2 of the TSC RS2AA–RS2MA datasheet (Version I2304).
Can RS2GA R3G be used in snubber circuits?
Yes, RS2GA R3G is explicitly recommended for snubber applications per its official Applications section. Its 150 ns trr, 5 µA IR at 25°C, and 50 pF junction capacitance provide predictable, low-loss clamping behavior. The glass-passivated junction ensures stable performance under repeated voltage transients, and the DO-214AC package supports direct mounting near high-dv/dt nodes on power PCBs.
