Product details
Overview
RS2JFS from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in SOD-128 package, featuring 250 ns reverse recovery time, 1.01 V forward voltage at 2 A/25°C, and 175°C maximum junction temperature. It serves as a primary output rectifier in high-frequency DC–DC converters requiring low conduction loss and thermal robustness.
For engineers reviewing the RS2JFS datasheet, RS2JFS pinout, RS2JFS application, or RS2JFS equivalent, key selection criteria include its 600 V VRRM, 250 ns trr for switching efficiency, SOD-128 thermal performance (RθJL = 16°C/W), and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
The RS2JFS employs a glass-passivated silicon die optimized for fast recovery in high-frequency power conversion topologies. Its single-die configuration delivers stable forward conduction with VF drift <0.25 V from 25°C to 125°C at 2 A, and IR remains ≤40 µA at 125°C under rated reverse voltage.
Thermal design leverages the SOD-128 package's low RθJL (16°C/W) when mounted on a 5 mm × 5 mm copper pad, enabling reliable operation up to 175°C junction temperature without derating in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input/output isolation in 48 V–400 V bus systems with 2× safety margin |
| IF | 2 A continuous - sustains steady-state current in mid-power SMPS outputs |
| trr | 250 ns - reduces switching losses in 100–500 kHz converters |
| VF @ 2 A, 25°C | 1.01 V - limits conduction loss to ~2.02 W at full load |
| RθJL | 16 °C/W - enables direct thermal coupling to PCB copper for passive cooling |
| Junction temp. max | 175 °C - allows operation in sealed industrial enclosures without forced air |

Applications
| AC–DC Adapter Output Rectification | Industrial DC–DC Converter Primary Side |
|---|---|
Use Scenario: 24 V/2 A isolated flyback adapter for factory automation I/O modules. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer secondary AC to regulated DC. Use Value: 250 ns trr and 1.01 V VF reduce output ripple and thermal rise vs. standard recovery diodes. | Use Scenario: 48 V input, 12 V/2 A half-bridge DC–DC converter in motor drive control boards. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement where gate drive complexity is avoided. Use Value: 600 V VRRM withstands reflected transients during MOSFET switching; RθJL = 16°C/W maintains <125°C junction under full load. |
| Telecom Power Supply Hold-up Rectification | LED Driver Constant-Current Stage |
Use Scenario: 48 V telecom shelf power with 10 ms hold-up requirement using bulk capacitors. IC Role / Device Role / Timing Role: Input bridge leg rectifier handling 2 A average current with 50 A surge tolerance. Use Value: 140 A IFSM (1 ms) ensures survival during line surges; 175°C TJMAX supports extended life at elevated ambient. | Use Scenario: Constant-current LED driver for street lighting with 36 V string voltage. IC Role / Device Role / Timing Role: Freewheeling path for buck regulator inductor current during off-cycle. Use Value: Low CJ (11 pF) minimizes capacitive coupling noise into current-sense circuitry; 250 ns trr prevents cross-conduction in high-frequency PWM dimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; trr = 150 ns (faster), VF = 1.15 V @ 2 A (higher) | Better for >300 kHz designs needing lower Qrr; higher VF increases conduction loss | Prefer STTH2R06 if switching frequency exceeds 250 kHz and thermal headroom permits higher VF |
| ES2J | Same SOD-128 package; trr = 35 ns (much faster), VF = 0.95 V @ 2 A (lower), but VRRM = 600 V identical | Superior for ultra-fast ZVS/ZCS topologies; tighter VF tolerance improves current sharing in parallel | Select ES2J only when trr <100 ns is mandatory and cost premium is acceptable |
Compared with STTH2R06 and ES2J, the RS2JFS offers balanced trade-offs: moderate trr (250 ns) with lowest VF among 600 V 2 A SOD-128 rectifiers, making it optimal for cost-sensitive 100–200 kHz industrial SMPS where thermal management prioritizes low conduction loss over minimal recovery charge.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the RS2JFS?
The RS2JFS has a maximum repetitive peak reverse voltage (VRRM) of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2304). This rating defines the highest reverse voltage the RS2JFS can block continuously without breakdown under specified thermal conditions, making it suitable for 400 V DC bus applications with safety margin.
Does the RS2JFS have a defined reverse recovery time (trr) and what is its value?
Yes, the RS2JFS specifies a reverse recovery time (trr) of 250 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as documented in the Electrical Specifications section of the Taiwan Semiconductor datasheet. This parameter directly impacts switching loss and EMI in high-frequency converters, and the RS2JFS uses this value to target 100–250 kHz power stages.
What package type does the RS2JFS use and what are its key mechanical features?
The RS2JFS uses the SOD-128 surface-mount package per JEDEC DO-221AD. Key mechanical features include a low profile (max height 1.20 mm), matte tin-plated leads compliant with J-STD-002 solderability, cathode polarity indicated by a band, and moisture sensitivity level 1-enabling unlimited floor life before reflow. The RS2JFS also meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
What is the forward voltage (VF) of the RS2JFS at 2 A and 25°C, and how does it change at elevated temperature?
The RS2JFS exhibits a typical forward voltage (VF) of 1.01 V at 2 A and 25°C, rising to 0.88 V at 2 A and 125°C per the Electrical Specifications table. This negative temperature coefficient reduces thermal runaway risk in parallel configurations, and the RS2JFS maintains stable conduction across its full operating range (−55°C to +175°C junction).
Is the RS2JFS RoHS compliant and halogen-free, and what certifications support this claim?
Yes, the RS2JFS is RoHS compliant and halogen-free, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version C2304). These attributes are verified per IPC-1752A material declarations and align with EU Directive 2011/65/EU and IEC 61249-2-21:2011, ensuring suitability for environmentally regulated industrial and telecom equipment where the RS2JFS is deployed.
