Product details
Overview
ES2AA R3G from Taiwan Semiconductor is a 2A, 50V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 2A/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency DC-DC converters.
For engineers reviewing the ES2AA R3G datasheet, ES2AA R3G pinout, ES2AA R3G application, or ES2AA R3G equivalent, key selection criteria include VRRM = 50V, IF = 2A, trr = 35ns, thermal resistance RθJA = 75°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. Its low-profile DO-214AC package supports high-density PCB layouts while meeting J-STD-020 moisture sensitivity level 1 and JESD 201 Class 2 whisker resistance.
The device operates with 35ns reverse recovery time under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions, enabling efficient switching in 100–500kHz power topologies. Junction capacitance is 25pF at 1MHz/4V, supporting minimal capacitive loading in snubber networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines minimum input/output isolation margin in 24V DC-DC designs |
| IF | 2 A - Continuous average forward current; supports sustained conduction in 24V/48W converter outputs |
| trr | 35 ns - Measured reverse recovery time; enables operation up to ~3 MHz effective switching frequency without excessive switching loss |
| VF @ 2A, 25°C | ≤0.95 V - Forward voltage drop; contributes ≤1.9W conduction loss at full load, critical for thermal budget in sealed enclosures |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; requires ≥150 mm² copper pour for safe 2A operation at 70°C ambient |
| IFSM | 50 A - Non-repetitive peak surge current; withstands inrush during cold-start of buck-derived LED drivers |
| Junction Temp | -55°C to +150°C - Operating range; validated for industrial ambient environments without derating below 125°C |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case with matte tin-plated leads, cathode band marking polarity, UL 94V-0 rated compound, 0.060g mass. Lead finish complies with J-STD-002 solderability standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck freewheel path); must route with low-inductance trace |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or ground return; determines voltage reference for snubber placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage current (<10 µA @ 25°C, <350 µA @ 125°C) and long-term reliability in humid industrial environments |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) to <15 nC, minimizing EMI and switching loss in high-frequency SMPS |
| DO-214AC (SMA) package | Low-profile (2.2mm height), JEDEC-compliant footprint compatible with standard SMT pick-and-place nozzles and reflow profiles |
| Moisture sensitivity level 1 | Zero floor life limitation - can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR220RLG | VRRM = 200V, trr = 35ns, VF = 1.15V @ 2A - higher blocking voltage but higher forward drop | Suitable for 110VAC input front-end rectification where 50V is insufficient | Select ES2AA R3G when VRRM = 50V and minimal VF are required; choose MUR220RLG only if higher reverse margin is needed. |
| Vishay VS-2EYH01-M3/5AT | VRRM = 100V, trr = 25ns, VF = 0.92V @ 2A - faster recovery but higher cost and different marking | Better suited for >400kHz resonant LLC topologies requiring sub-30ns trr | ES2AA R3G remains optimal for cost-sensitive 200–300kHz flyback designs; VS-2EYH01-M3/5AT adds value only if trr reduction below 30ns is verified critical. |
Compared with MUR220RLG and VS-2EYH01-M3/5AT, ES2AA R3G delivers the lowest forward voltage (≤0.95V) at its 50V rating, making it uniquely suitable for low-voltage, high-efficiency DC-DC stages where conduction loss dominates thermal design - without over-specifying reverse voltage or paying premium for ultra-fast variants.

FAQ
What is the maximum junction temperature rating for ES2AA R3G?
The ES2AA R3G has a maximum junction temperature (TJ) rating of +150°C, with operational capability from -55°C to +150°C. This rating is validated per TSC's M2102 specification revision and supports use in enclosed industrial power supplies where ambient temperatures reach 70–85°C, provided PCB copper area and airflow meet thermal derating curves in the ES2AA R3G datasheet.
Does ES2AA R3G have a RoHS-compliant and halogen-free construction?
Yes, ES2AA R3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are confirmed in Taiwan Semiconductor's M2102 datasheet version and apply to all ES2AA R3G units shipped with green compound marking.
What is the reverse recovery time (trr) test condition for ES2AA R3G?
The reverse recovery time of 35ns for ES2AA R3G is measured under the condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, per the ES2AA R3G electrical specifications table in TSC's M2102 datasheet. This standardized test ensures consistent comparison across super fast rectifiers used in switching power applications.
Can ES2AA R3G replace a standard FR107 diode in existing designs?
ES2AA R3G can replace FR107 in designs where 50V VRRM is sufficient and faster recovery is beneficial. Unlike FR107 (trr ≈ 500ns), ES2AA R3G's 35ns trr reduces switching loss and EMI, but requires verification of layout parasitics and thermal interface due to higher-frequency operation. No PCB changes are needed if DO-214AC footprint matches.
What does the 'R3G' suffix indicate in ES2AA R3G?
The 'R3G' suffix in ES2AA R3G denotes Taiwan Semiconductor's tape-and-reel packaging variant: R3 = 7,500 units per reel, G = green compound molding material. This marking aligns with TSC's ordering code convention defined in the ES2AA R3G datasheet's "Ordering Information" section and confirms compliance with halogen-free and RoHS requirements.
