Product details
Overview
RS2JAHR3G 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 requiring high efficiency and thermal robustness.
For engineers reviewing the RS2JAHR3G datasheet, RS2JAHR3G pinout, RS2JAHR3G application, or RS2JAHR3G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), junction-to-lead thermal resistance (18 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and suitability for automated SMT placement.
Technical Context
This single-die, glass-passivated fast recovery rectifier operates with a maximum junction temperature of 175°C and supports surge currents up to 50 A (8.3 ms half-sine). Its 50 pF junction capacitance at 1 MHz and 4.0 V reverse bias enables stable high-frequency switching behavior in snubber networks and flyback secondary-side rectification.
The device uses a cathode-band polarity indicator and matte tin-plated leads compliant with J-STD-002 solderability. Thermal performance is defined by RθJL = 18 °C/W and RθJA = 55 °C/W, enabling reliable operation under convection-cooled PCB layouts without forced airflow.
Key Specifications

| IF | 1.5 A continuous - Supports average forward current up to 1.5 A at TL ≤ 75°C on standard FR-4 PCB |
| trr | 250 ns - Enables efficient high-frequency switching (>100 kHz) with low switching loss in SMPS designs |
| VF max | 1.3 V @ 1.5 A - Limits conduction loss to ≤1.95 W per device at full rated current |
| IR max | 5 µA @ 25°C - Ensures minimal leakage power in high-impedance hold-up or sensing circuits |
| RθJL | 18 °C/W - Allows direct thermal coupling to copper pour for effective junction heat extraction |
| MSL | Level 1 (J-STD-020) - No floor life limitation; safe for standard reflow without baking |

Applications
| Offline AC-DC Adapters | Flyback Converter Secondary Rectification |
|---|---|
Use Scenario: 12 V/1.2 A universal-input wall adapter powering IoT sensors and smart home hubs. IC Role / Device Role / Timing Role: Primary output rectifier converting transformer secondary AC to regulated DC; handles 1.5 A average load with 600 V PIV margin. Use Value: 250 ns trr minimizes switching loss during diode turn-off, improving adapter efficiency by ~0.8% at full load vs. standard recovery alternatives. | Use Scenario: 5 V/2 A isolated auxiliary supply in industrial PLC power modules. IC Role / Device Role / Timing Role: Fast-recovery rectifier on flyback secondary winding; clamps reverse voltage during MOSFET off-time. Use Value: 18 °C/W RθJL allows direct thermal coupling to ground plane, maintaining TJ < 125°C without heatsink at 1.5 A continuous. |
| Snubber Networks | LED Driver Output Stage |
Use Scenario: RC-D clamp snubber across primary-side MOSFET in 30 W LED driver. IC Role / Device Role / Timing Role: Fast recovery diode conducting snubber capacitor discharge pulse; requires low Qrr and stable CJ. Use Value: 50 pF CJ at 4 V ensures predictable snubber timing; 250 ns trr prevents reverse conduction overlap during high dv/dt transitions. | Use Scenario: Constant-current output rectification in 24 V, 700 mA outdoor LED streetlight driver.

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 | 1 A / 600 V, 75 ns trr, TO-277 package (lower IF, faster trr, different footprint) | Higher switching frequency suitability but lower current rating limits use in >1.2 A outputs | Select when prioritizing ultra-fast recovery over current capacity and board space permits TO-277 layout |
| ON Semi MUR160 | 1 A / 600 V, 50 ns trr, DO-41 package (lower IF, faster trr, axial lead) | Not SMT-compatible; unsuitable for automated assembly or high-density layouts | Choose only for through-hole prototyping or legacy repair where DO-41 footprint exists |
Compared with STTH1L06U and MUR160, RS2JAHR3G uniquely balances 1.5 A current capability, 250 ns recovery, and DO-214AC SMT compatibility-making it optimal for cost-sensitive, medium-power AC-DC adapters requiring production-ready manufacturability.

FAQ
What is the maximum junction temperature rating for RS2JAHR3G?
The RS2JAHR3G has a maximum junction temperature (TJ) rating of +175°C, allowing operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. This rating is validated under steady-state conditions with proper PCB copper area and is supported by its 18 °C/W junction-to-lead thermal resistance. Derating curves in the RS2JAHR3G datasheet define safe operating current versus lead temperature.
Does RS2JAHR3G meet RoHS and halogen-free requirements?
Yes, RS2JAHR3G is RoHS compliant and halogen-free per TSC's specification I2304. The molding compound, lead finish, and internal construction exclude restricted substances including lead, cadmium, mercury, hexavalent chromium, PBB, PBDE, and chlorine/bromine-based flame retardants. Full material declarations are available upon request for RS2JAHR3G compliance documentation.
What is the reverse recovery time (trr) of RS2JAHR3G and how is it measured?
The RS2JAHR3G has a reverse recovery time (trr) of 250 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test methodology. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss in high-frequency converters. The 250 ns trr is confirmed across the full operating temperature range.
Is RS2JAHR3G suitable for automated SMT assembly?
Yes, RS2JAHR3G is explicitly designed for automated placement, with DO-214AC (SMA) package dimensions and matte tin-plated leads compliant with J-STD-002 solderability standards. Its J-STD-020 moisture sensitivity level is Grade 1, eliminating bake requirements before reflow. The RS2JAHR3G marking code "RS2JA" and cathode band ensure reliable optical recognition during placement.
How does RS2JAHR3G compare to RS2KAHR3G in terms of voltage rating and application scope?
RS2JAHR3G is rated for 600 V VRRM, while RS2KAHR3G is rated for 800 V VRRM. Both share identical current rating (1.5 A), thermal specs, and package. RS2JAHR3G is optimized for universal-input (85–265 VAC) offline converters where 600 V provides sufficient margin; RS2KAHR3G suits higher-line applications like 305 VAC industrial inputs or designs requiring extended PIV safety margin beyond 600 V.
