Product details
Overview
RS2GFL from Taiwan Semiconductor is a 2 A, 400 V fast recovery surface-mount rectifier diode in SOD-123FL package, featuring 150 ns reverse recovery time, 0.94 V forward voltage at 2 A/25°C, and 81 °C/W junction-to-lead thermal resistance. It serves as primary output rectifier in DC-DC converters and switching-mode power supplies.
For engineers reviewing the RS2GFL datasheet, RS2GFL pinout, RS2GFL application, or RS2GFL equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, low 5 µA max reverse leakage at 25°C, fast 150 ns trr, SOD-123FL footprint compatibility, and suitability for automated placement in high-efficiency SMPS designs.
Technical Context
The RS2GFL integrates a glass-passivated silicon junction optimized for fast recovery (trr ≤ 150 ns) and low conduction loss, with VF = 0.94 V at 2 A/25°C and VF = 0.84 V at 2 A/125°C. Its thermal design supports 150°C maximum junction temperature and 81 °C/W RθJL when mounted on a 5 mm × 5 mm copper pad.
It operates as a single-die, unidirectional, cathode-banded rectifier with polarity indicated by a visible band. The device meets JESD201 Class 1 whisker resistance, J-STD-020 Level 1 moisture sensitivity, RoHS, and halogen-free (IEC 61249-2-21) requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| AC-DC Adapter Secondary Rectification | Isolated DC-DC Converter Output Stage |
|---|---|
Use Scenario: 12 V/2 A output stage in 24 V input wall adapter with 250 kHz flyback topology. IC Role / Device Role / Timing Role: Unidirectional power conversion element; conducts only during positive half-cycle of transformer secondary voltage. Use Value: 0.94 V VF at 2 A reduces conduction loss to <1.9 W, enabling thermally robust layout without heatsink. | Use Scenario: 5 V/2 A isolated rail in industrial PLC power module using active-clamp forward converter. IC Role / Device Role / Timing Role: Synchronous rectifier replacement alternative; provides fixed-timing uncontrolled rectification with 150 ns trr. Use Value: 150 ns trr limits reverse recovery charge (Qrr) to <15 nC, minimizing switching node ringing and EMI filter burden. |
| USB PD Power Delivery Interface | Telecom DC Power Distribution |
Use Scenario: Input rectification for 20 V/3 A USB PD 3.0 buck-boost controller supply rail. IC Role / Device Role / Timing Role: Front-end AC/DC or HV DC rectifier; blocks reverse current during transient overvoltage events. Use Value: 400 V VRRM provides 100% margin over 20 V × 1.5× safety factor + line transients, ensuring long-term reliability. | Use Scenario: -48 V backup power feed rectification in telecom shelf management unit. IC Role / Device Role / Timing Role: Reverse-polarity protection and DC bus isolation diode; prevents backfeed from redundant supplies. Use Value: ≤5 µA IR at 25°C and ≤150 µA at 125°C ensures negligible standby current drain across wide ambient range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR240 | Same 2 A / 400 V rating, but TO-220AC package (larger footprint, higher RθJA = 50 °C/W) | Requires heatsink for >1 A continuous; unsuitable for ultra-thin or space-constrained layouts | Choose MUR240 only if board-level thermal mass is insufficient for SOD-123FL mounting |
| Vishay VS-2EYH04-M3 | Same SOD-123FL package, but 400 V VRRM, 1.15 V VF @ 2 A/25°C, 200 ns trr | Higher conduction loss (+0.21 V) and slower recovery increase losses in >300 kHz designs | Accept VS-2EYH04-M3 only if VF and trr margins allow 5–8% efficiency reduction at full load |
Compared with MUR240 and VS-2EYH04-M3, RS2GFL delivers superior power density via SOD-123FL packaging, lower VF (0.94 V), and faster trr (150 ns), making it optimal for compact, high-frequency, thermally constrained 2 A rectification tasks.

FAQ
What is the maximum junction temperature rating for RS2GFL?
The RS2GFL has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed power supplies or industrial enclosures. Derating begins above 75°C ambient, per the forward current derating curve in the RS2GFL datasheet. Thermal design must maintain TJ ≤ 150°C under worst-case load and ambient conditions.
Does RS2GFL support lead-free reflow soldering?
Yes, RS2GFL supports lead-free reflow soldering per J-STD-002. Its matte tin-plated leads are fully compatible with standard Pb-free reflow profiles (peak 260°C, 10 s max). The device is rated J-STD-020 Level 1 for moisture sensitivity, eliminating the need for baking prior to assembly-reducing process complexity and cost in high-volume manufacturing of RS2GFL-based power stages.
What is the reverse recovery time (trr) specification for RS2GFL?
The RS2GFL reverse recovery time is specified as ≤150 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table and applies across the full operating temperature range. The 150 ns trr directly contributes to reduced switching losses and lower EMI generation in high-frequency SMPS designs where RS2GFL is deployed.
How does RS2GFL compare to RS2DFL in terms of voltage rating and forward voltage?
RS2GFL has a 400 V VRRM rating versus RS2DFL's 200 V, while both share identical 2 A IF and SOD-123FL packaging. At 2 A/25°C, RS2GFL exhibits VF = 0.94 V, slightly higher than RS2DFL's 0.94 V (same typ value), but RS2GFL's VF at 125°C is 0.84 V-matching RS2DFL's performance under thermal stress. This makes RS2GFL the preferred choice for 400 V-class applications without sacrificing thermal robustness.
Is RS2GFL halogen-free and RoHS compliant?
Yes, RS2GFL is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are explicitly confirmed in the FEATURES section of the official RS2GFL datasheet. The molding compound, plating, and internal construction meet both regulatory requirements, supporting environmentally conscious design and global market access for products incorporating RS2GFL.
