Product details
Overview
RS2JA R3G from Taiwan Semiconductor is a 1.5A, 600V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 250 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 offline DC-DC converters and snubber circuits.
For engineers reviewing the RS2JA R3G datasheet, RS2JA R3G pinout, RS2JA R3G application, or RS2JA R3G equivalent, key selection criteria include repetitive peak reverse voltage (600 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 SMT placement.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve stable switching performance across -55°C to +175°C junction temperature range. Its 250 ns trr and low 50 pF junction capacitance support high-frequency operation in switch-mode power supplies up to several hundred kHz.
The device operates with 50 A non-repetitive surge current capability and exhibits 18 °C/W junction-to-lead thermal resistance, enabling efficient heat transfer to PCB copper when mounted per recommended pad layout. Polarity is unambiguously indicated by cathode band marking.

Applications
| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–24 V at ≤1.5 A. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC output. Use Value: 250 ns trr and 1.3 V VF minimize conduction and switching losses, improving efficiency by ~0.8% over slower 600 V alternatives. | Use Scenario: Clamp diode in RCD snubber networks across MOSFETs or transformers in high-voltage switching stages. IC Role / Device Role / Timing Role: Fast turn-off path for transient energy dissipation during MOSFET turn-off events. Use Value: Low Qrr and 600 V VRRM enable reliable clamping of 400–600 V spikes without oscillation or secondary breakdown. |
| Lighting Power Supply | Switching Mode Inverter |
Use Scenario: Input bridge or output rectifier in LED driver modules for commercial lighting (e.g., T8 retrofit, panel lights). IC Role / Device Role / Timing Role: High-reliability rectification element operating continuously at elevated ambient temperatures (≥70°C). Use Value: 175°C TJ max and 18 °C/W RθJL allow sustained operation at full current in compact, thermally constrained enclosures. | Use Scenario: Freewheeling or commutation diode in half-bridge inverters for HVAC blowers or small motor drives. IC Role / Device Role / Timing Role: Provides controlled current recirculation path during PWM dead-time intervals. Use Value: Consistent 250 ns trr ensures predictable timing margin between high-side and low-side switching, preventing shoot-through. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | 1.2 A IF, 600 V VRRM, 150 ns trr, TO-277 package | Lower current rating; requires derating above 1.2 A; different footprint | Select if faster recovery is prioritized and current demand stays ≤1.2 A |
| ES1J | 1 A IF, 600 V VRRM, 35 ns trr, DO-214AC package | Lower current rating; significantly faster but unsuitable for 1.5 A continuous loads | Choose only for signal-level or low-current snubbing where speed dominates |
Compared with STTH1L60S and ES1J, RS2JA R3G uniquely balances 1.5 A continuous current, 600 V blocking, 250 ns recovery, and DO-214AC compatibility-making it optimal for cost-sensitive, medium-power industrial and lighting SMPS where both current and speed matter.

FAQ
What is the maximum junction temperature rating for RS2JA R3G?
The RS2JA R3G has a maximum junction temperature (TJ MAX) of +175°C, allowing operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. This rating is validated per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2304. Derating curves confirm usable current capacity down to 0.8 A at 125°C ambient with standard PCB copper area.
Does RS2JA R3G meet RoHS and halogen-free requirements?
Yes, RS2JA R3G is RoHS compliant and halogen-free per Taiwan Semiconductor's product documentation (Version I2304). The molding compound and lead finish satisfy EU Directive 2011/65/EU and JEDEC JS709B definitions for halogen-free materials (<900 ppm bromine, <900 ppm chlorine, total halogens <1500 ppm). Full material declarations are available upon request.
What is the reverse recovery time (trr) specification for RS2JA R3G?
The RS2JA R3G has a maximum reverse recovery time (trr) of 250 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions per the official electrical specifications table. This value is confirmed across the RS2JA variant group and distinguishes it from RS2GA (150 ns) and RS2KA (500 ns) within the same family.
Is RS2JA R3G pin-compatible with other DO-214AC rectifiers like RS2AA or RS2MA?
Yes, RS2JA R3G shares identical DO-214AC (SMA) package dimensions, anode/cathode terminal configuration, and polarity marking (cathode band) with all RS2xx series devices including RS2AA and RS2MA. Mechanical compatibility is guaranteed per JEDEC DO-214AC standard and verified in the package outline drawing (HQ2SD07-DO214SMC-034 REV A).
What is the forward voltage drop of RS2JA R3G at rated current?
The RS2JA R3G exhibits a maximum forward voltage (VF) of 1.3 V at 1.5 A and 25°C junction temperature, as specified in the electrical characteristics table. At 125°C, VF decreases slightly due to negative temperature coefficient of silicon PN junctions, remaining below 1.25 V under typical operating conditions.
