Product details
Overview
ES2GA R3G from Taiwan Semiconductor is a 2A, 400V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 2A/25°C, and 50A peak surge current - deployed in DC-DC converters and snubber circuits for high-frequency switching efficiency.
For engineers reviewing the ES2GA R3G datasheet, ES2GA R3G pinout, ES2GA R3G application, or ES2GA R3G equivalent, key selection criteria include VRRM = 400V, IF = 2A, trr = 35ns, 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 thermal performance up to 150°C junction temperature and low leakage (<10µA @ 25°C, <350µA @ 125°C). Its 35ns recovery time enables operation in high-frequency SMPS topologies where diode switching loss must be minimized.
The DO-214AC (SMA) package provides 20°C/W junction-to-lead thermal resistance and supports reflow soldering per J-STD-002; polarity is marked by cathode band, and moisture sensitivity is rated Level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage; defines safe blocking capability in 400V-rated power rails |
| IF | 2 A - continuous average forward current; sets thermal design baseline for PCB copper area and ambient conditions |
| trr | 35 ns - reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables >100 kHz switching without excessive diode turn-off loss |
| VF max | 1.30 V @ 2A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| IFSM | 50 A - non-repetitive peak surge current (8.3ms sine); supports inrush and transient overload handling in power supplies |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; determines required heatsinking or board layout for TJ ≤ 150°C |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case meeting UL 94V-0, matte tin-plated leads, cathode indicated by band, weight ≈ 0.060g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires low-inductance trace routing |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or snubber network; critical for EMI control in high-dI/dt paths |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under thermal cycling and humidity exposure per J-STD-020 Level 1 |
| Super fast recovery (35 ns) | Reduces switching loss and EMI generation in 100–500 kHz DC-DC converters compared to standard rectifiers |
| Low profile DO-214AC (SMA) | Supports automated pick-and-place and compact board layouts; height ≤ 2.3 mm per JEDEC outline |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained industrial and consumer designs |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters operating at 100–300 kHz. IC Role / Device Role / Timing Role: Output rectifier handling continuous 2A load with minimal conduction and switching loss. Use Value: 35ns trr and 1.30V VF reduce total power loss versus slower 1N5822-class diodes, improving efficiency by ~0.8% at full load. | Use Scenario: RC snubber across MOSFET drain-source in hard-switched PFC or LLC stages. IC Role / Device Role / Timing Role: Fast clamping diode absorbing voltage spikes during MOSFET turn-off. Use Value: Sub-40ns recovery ensures rapid recombination, minimizing energy dissipation in the snubber resistor and improving spike suppression fidelity. |
| Lighting Driver | Freewheeling Diode |
Use Scenario: Output rectification in constant-current LED drivers for commercial lighting with 400V bus. IC Role / Device Role / Timing Role: High-voltage rectifier delivering regulated current to LED strings while surviving line transients. Use Value: 400V VRRM provides 2× margin over 230VAC-derived 280V DC bus, ensuring robustness against surge events per IEC 61000-4-5. | Use Scenario: Inductive load freewheeling path in solenoid or relay driver circuits. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when inductive load is de-energized. Use Value: 50A IFSM withstands high-energy back-EMF pulses without degradation, extending system lifetime in industrial control modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | VRRM = 400V, trr = 30ns, VF = 1.25V @ 2A - slightly faster but higher cost | Better suited for >300 kHz designs requiring minimal reverse recovery charge | Select STTH2R04 if trr reduction below 35ns is critical and budget allows premium pricing |
| MBR240 | VRRM = 40V, Schottky architecture, VF = 0.52V - lower VF but insufficient voltage rating | Only viable in sub-40V systems; cannot replace ES2GA R3G in 400V applications | Reject MBR240 for 400V use; consider only for low-voltage, ultra-low-loss scenarios where VRRM ≤ 40V |
Compared with STTH2R04 and MBR240, ES2GA R3G delivers optimal balance of 400V blocking, 35ns recovery, and cost-effective DO-214AC packaging - making it the preferred choice for mainstream 100–250 kHz industrial and lighting power supplies where voltage rating and thermal robustness are primary constraints.

FAQ
What is the maximum junction temperature rating for ES2GA R3G?
The ES2GA R3G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version M2102). This allows reliable operation in enclosed industrial enclosures with ambient temperatures up to 85°C when mounted on 1-in² 2-oz copper with thermal vias. The ES2GA R3G must not exceed this limit during steady-state or transient conditions.
Does ES2GA R3G have a RoHS and halogen-free certification?
Yes, ES2GA R3G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor ES2AA–ES2JA datasheet (Version M2102). The molding compound and plating meet these requirements without exception, and full compliance documentation is available upon request from Aetrix Electronics.
What is the reverse recovery time (trr) test condition for ES2GA R3G?
The reverse recovery time of 35 ns for ES2GA R3G is measured under the standardized condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version M2102). This test setup reflects real-world switching behavior in flyback and forward converters and is not extrapolated from other variants in the ES2x family.
Can ES2GA R3G replace ES2FA in an existing design?
Yes, ES2GA R3G can directly replace ES2FA because both share identical DO-214AC (SMA) packaging, pinout, thermal characteristics, and electrical parameters except VRRM: ES2FA = 300V, ES2GA R3G = 400V. The higher voltage rating of ES2GA R3G provides additional margin without altering layout, thermal design, or drive circuitry - making it a safe upgrade for improved surge immunity.
What is the moisture sensitivity level (MSL) of ES2GA R3G?
ES2GA R3G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates floor-life constraints and simplifies SMT line logistics - confirmed in the "Features" section of the Taiwan Semiconductor ES2AA–ES2JA datasheet (Version M2102).
