Product details
Overview
RS2JFL from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in SOD-123FL package, featuring 1.09 V forward voltage at 2 A/25°C, 250 ns reverse recovery time, and 9 pF junction capacitance. It serves as a primary output rectifier in DC–DC converters and switching-mode power supplies operating up to 150°C junction temperature.
For engineers reviewing the RS2JFL datasheet, RS2JFL pinout, RS2JFL application, or RS2JFL equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, low leakage (≤5 µA @ 25°C), thermal resistance (RθJA = 116 °C/W), and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
The RS2JFL uses a glass-passivated silicon die optimized for fast recovery (trr ≤ 250 ns) and low forward conduction loss at elevated temperatures. Its single-die configuration and SOD-123FL package support high-density board layouts while maintaining reliable thermal dissipation under continuous 2 A DC load.
Designed for operation across –55°C to +150°C, the device delivers stable reverse leakage (<150 µA @ 125°C) and maintains VF < 1.02 V at 2 A/125°C - critical for efficiency retention in thermally constrained switch-mode power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input/output isolation in 48 V–400 V bus applications without derating |
| IF | 2 A continuous - enables use in compact 10–30 W SMPS without heatsinking |
| trr | 250 ns - reduces switching losses and EMI in 100–500 kHz converters |
| VF @ 2 A, 25°C | 1.09 V - limits conduction loss to ~2.2 W at full load, easing thermal management |
| CJ | 9 pF - minimizes capacitive coupling noise in high-frequency gate-drive or sensing paths |
| RθJA | 116 °C/W - allows ~75°C rise above ambient at 2 A on 5 mm × 5 mm Cu pad |
Pinout & Package
SOD-123FL surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 1 whisker resistance.

Applications
| AC–DC Adapter Output Rectification | DC–DC Converter Secondary Side |
|---|---|
Use Scenario: 12 V/2 A isolated flyback adapter powering network routers or set-top boxes. IC Role / Device Role / Timing Role: Primary unidirectional current path converting transformer AC output to regulated DC, absorbing reverse recovery energy during MOSFET turn-on. Use Value: 600 V VRRM provides margin against reflected transients; 250 ns trr limits cross-conduction loss with synchronous rectifiers. | Use Scenario: 5 V/2 A buck-derived auxiliary rail in telecom base station power modules. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductor current during high-side switch off-time in non-synchronous topologies. Use Value: 1.09 V VF at 2 A ensures <2.2 W conduction loss; SOD-123FL footprint enables dense layout near controller IC. |
| Industrial Sensor Power Supply | LED Driver Flyback Output |
Use Scenario: 24 V input, 5 V/1.5 A isolated sensor interface module operating in factory ambient (70°C). IC Role / Device Role / Timing Role: Output rectifier delivering stable low-noise DC to analog signal conditioning circuitry. Use Value: 9 pF CJ minimizes capacitive feedthrough of switching noise into sensitive analog ground; 150°C TJMAX supports extended life at elevated ambient. | Use Scenario: Constant-current LED driver for commercial lighting with 36 V string voltage. IC Role / Device Role / Timing Role: High-efficiency output rectifier handling pulsed LED current with minimal forward drop-induced dimming variation. Use Value: Stable VF < 1.02 V at 125°C prevents thermal runaway in enclosed fixtures; 2 A rating covers 150% surge during soft-start. |
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 600 V VRRM, 2 A IF, but TO-220AC package (larger footprint, RθJA ≈ 65 °C/W) | Requires heatsink for >1 A continuous; unsuitable for ultra-thin or space-constrained designs | Choose when higher thermal mass or legacy through-hole compatibility is required |
| MBR260 | 60 V VRRM, Schottky architecture - zero trr, but higher leakage (>100 µA @ 125°C) | Only viable in low-voltage DC–DC outputs; cannot replace RS2JFL in 48 V+ input systems | Consider only for <40 V output rails where ultra-low VF (<0.6 V) outweighs reverse voltage limitation |
Compared with STTH2R06 and MBR260, the RS2JFL uniquely balances 600 V capability, SOD-123FL compactness, and 250 ns recovery in a moisture-resistant, halogen-free package - making it optimal for modern SMT-based mid-power SMPS where board area and thermal profile are tightly constrained.

FAQ
What is the maximum junction temperature rating for RS2JFL?
The RS2JFL has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version B2103. This allows continuous operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. Derating curves confirm usable current capacity down to 1.2 A at 125°C ambient on standard PCB mounting.
Does RS2JFL have a specified reverse recovery time, and how is it measured?
Yes, RS2JFL has a specified 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 the Taiwan Semiconductor datasheet. This parameter is critical for minimizing switching losses in high-frequency converters and is validated across the full temperature range (25°C to 125°C).
What is the marking code printed on the RS2JFL device body?
The RS2JFL is marked with "R2JF" on its cathode-banded surface, as confirmed in the Absolute Maximum Ratings table of the Taiwan Semiconductor datasheet. This 4-character laser marking distinguishes it from other variants in the RS2xFL series (e.g., RS2DFL = R2DF, RS2KFL = R2KF) and aligns with industry-standard SOD-123FL identification practices.
Is RS2JFL compatible with lead-free reflow soldering processes?
Yes, RS2JFL is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device is rated for MSL Level 1 per J-STD-020 - meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. The SOD-123FL package withstands peak reflow temperatures up to 260°C.
How does the junction capacitance of RS2JFL affect EMI performance in high-frequency designs?
RS2JFL exhibits a typical junction capacitance (CJ) of 9 pF at 1 MHz and 4.0 V reverse bias. This low value reduces high-frequency displacement current during switching transitions, directly lowering common-mode EMI generation in flyback and forward converters operating above 250 kHz. Measured data confirms CJ remains stable across temperature, supporting consistent noise filtering behavior.
