Product details
Overview
RS2DA R3G from Taiwan Semiconductor is a 1.5A, 200V 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. It serves as a primary output rectifier in DC-DC converters and snubber circuits requiring high efficiency and thermal robustness.
For engineers reviewing the RS2DA R3G datasheet, RS2DA R3G pinout, RS2DA R3G application, or RS2DA R3G equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 50 A surge rating, 175°C maximum junction temperature, DO-214AC mechanical compatibility, and RoHS/halogen-free compliance for industrial power designs.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve stable switching performance across -55°C to +175°C operating range. Its 150 ns trr and low 50 pF junction capacitance support high-frequency operation in SMPS topologies without excessive switching loss.
The device exhibits 18°C/W junction-to-lead thermal resistance and 55°C/W junction-to-ambient rating, enabling reliable conduction at full 1.5 A average current with appropriate PCB copper area. Polarity is unambiguously indicated by cathode band per JEDEC DO-214AC standard.

Applications
| DC-DC Converter Output Rectification | Snubber Network Clamp Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/1.5 A buck-derived flyback converter powering industrial PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; conducts during positive half-cycle only. Use Value: 150 ns trr minimizes overlap loss with synchronous MOSFET gate drive; 1.3 V VF limits conduction loss to <0.5 W at full load. | Use Scenario: RCD snubber across primary-side MOSFET in 65 kHz offline SMPS for LED driver. IC Role / Device Role / Timing Role: Fast clamp diode capturing inductive energy spike during MOSFET turn-off; must recover before next switching cycle. Use Value: 150 ns trr ensures full recovery within 15.4 µs (1/65 kHz period), preventing voltage doubling and MOSFET overstress. |
| Switching Inverter Freewheeling | Lighting Ballast Rectification |
Use Scenario: Freewheeling path in 3-phase IGBT inverter driving HVAC compressor motor. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when IGBTs are off; handles bidirectional reactive current. Use Value: 50 A IFSM withstands motor startup surges; 175°C TJ max allows operation near heatsink baseplate. | Use Scenario: Input rectification stage in electronic ballast for T8 fluorescent lamp (220 V AC input). IC Role / Device Role / Timing Role: Converts line AC to pulsating DC for high-frequency inverter stage; operates at 50/60 Hz with high peak current margin. Use Value: 200 V VRRM provides 2× safety margin over 220 V RMS line; 5 µA IR prevents capacitor discharge in standby mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L20U (STMicroelectronics) | 1.2 A IF, 200 V VRRM, 110 ns trr, DO-214AC package | Lower average current rating; tighter trr spec but reduced thermal margin | Preferred where space-constrained layout demands lowest possible trr and board-level thermal management is optimized |
| ES1D (ON Semiconductor) | 1.0 A IF, 200 V VRRM, 35 ns trr, DO-214AC package | Higher speed but 33% lower IF; not suitable for sustained 1.5 A loads | Applicable only in low-duty-cycle or pulsed-current snubber roles where peak current dominates average rating |
Compared with STTH1L20U and ES1D, RS2DA R3G delivers higher continuous current capability (1.5 A vs. 1.2 A/1.0 A) and superior thermal resilience (175°C TJ max), making it optimal for thermally demanding industrial DC-DC and inverter freewheeling where reliability outweighs marginal trr reduction.

FAQ
What is the maximum junction temperature rating for RS2DA R3G?
The RS2DA R3G has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating allows the RS2DA R3G to operate reliably in sealed industrial enclosures or near heat-generating components without derating at ambient temperatures up to 75°C when mounted on ≥1 cm² 2-oz copper.
Does RS2DA R3G meet RoHS and halogen-free requirements?
Yes, RS2DA R3G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The device uses bromine-free flame-retardant molding compound meeting UL 94V-0, and matte tin-plated leads free of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE.
What is the reverse recovery time (trr) specification for RS2DA R3G?
The RS2DA R3G has a maximum reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the Taiwan Semiconductor RS2AA–RS2MA datasheet (Version I2304) and applies specifically to the RS2DA variant.
Is RS2DA R3G suitable for use in snubber circuits?
Yes, RS2DA R3G is explicitly listed in the Applications section of its datasheet for snubber use. Its 150 ns trr, 50 A IFSM, and low 5 µA reverse leakage at 25°C make it effective in RCD snubbers for MOSFET/IGBT protection in switching inverters and SMPS, where fast recovery and surge tolerance are critical.
What package type does RS2DA R3G use, and what are its key mechanical features?
RS2DA R3G uses the DO-214AC (SMA) surface-mount package. Key mechanical features include UL 94V-0 flammability-rated molding compound, matte tin-plated solderable leads compliant with J-STD-002, cathode polarity indicated by visible band, and JESD201 Class 2 whisker resistance - all confirmed in the Mechanical Data section of the official datasheet.
