Product details
Overview
ES2JA R3G from Taiwan Semiconductor is a 2A, 600V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 1.70V max forward voltage at 2A/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency switching power supplies.
For engineers reviewing the ES2JA R3G datasheet, ES2JA R3G pinout, ES2JA R3G application, or ES2JA R3G equivalent, key selection criteria include VRRM = 600V, IF = 2A, trr = 35ns, thermal resistance RθJA = 75°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
This discrete rectifier uses a glass-passivated silicon junction for stable operation up to 150°C junction temperature and supports repetitive peak reverse voltages up to 600V. Its super-fast recovery enables efficient operation in DC-DC converters and switching inverters operating above 50kHz.
The device exhibits low junction capacitance (20pF at 1MHz/4V), low leakage (≤10µA at 25°C, ≤350µA at 125°C), and meets J-STD-020 moisture sensitivity level 1 - enabling standard reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in snubber or freewheeling circuits. |
| IF | 2 A continuous - Rated average forward current at TL = 75°C; determines heatsink-free power handling in compact layouts. |
| trr | 35 ns - Measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables high-frequency switching with minimal switching loss. |
| VF (max) | 1.70 V at 2A/25°C - Forward voltage drop directly impacts conduction loss and thermal rise in DC-DC output stages. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance under standard PCB mounting; used to calculate max ambient temperature for 150°C TJ. |
| IFSM | 50 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush and transient overload tolerance. |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case with matte tin-plated leads, polarity indicated by cathode band, UL 94V-0 rated compound, 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); must handle full IF and IFSM. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); blocks 600V reverse during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr ≤ 35 ns) | Reduces switching losses and EMI generation in >100kHz SMPS designs compared to standard fast recovery diodes. |
| Glass passivated junction | Ensures long-term reliability and stable leakage performance across temperature and humidity stress conditions. |
| Moisture sensitivity level 1 | Eliminates pre-bake requirement before reflow soldering, reducing manufacturing cycle time and cost. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS directives for environmentally restricted substances in industrial and consumer products. |
Applications
| DC-DC Converter Output Stage | Snubber Network in Flyback Converters |
|---|---|
Use Scenario: Used as secondary-side rectifier in isolated 24–48V output DC-DC modules delivering up to 48W. IC Role / Device Role / Timing Role: Freewheeling rectifier conducting during transformer reset phase; handles bidirectional energy transfer. Use Value: 35ns trr minimizes reverse recovery charge (Qrr) and associated switching loss, improving efficiency by ~0.8% at 250kHz. | Use Scenario: Placed across primary-side MOSFET and transformer in flyback topology to clamp voltage spikes. IC Role / Device Role / Timing Role: Transient voltage clamping diode absorbing leakage inductance energy during MOSFET turn-off. Use Value: 600V VRRM ensures reliable clamping margin above reflected output voltage + spike overshoot in 24V-input systems. |
| LED Driver Secondary Rectification | Industrial Inverter Freewheeling Path |
Use Scenario: Rectifies high-frequency AC from resonant LLC transformer in constant-current LED drivers. IC Role / Device Role / Timing Role: Output rectifier synchronizing with transformer zero-voltage switching transitions. Use Value: Low CJ (20pF) reduces capacitive loading on transformer secondary, preserving ZVS timing integrity. | Use Scenario: Provides freewheeling path for inductive motor current during PWM dead-time in 3-phase VFDs. IC Role / Device Role / Timing Role: Bidirectional conduction path enabling smooth current decay when IGBTs are off. Use Value: 150°C TJMAX and 50A IFSM support short-circuit robustness and thermal cycling in 40°C ambient industrial enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | VRRM = 600V, trr = 35ns, VF = 1.7V @ 2A, but RθJA = 80°C/W vs. 75°C/W for ES2JA R3G | Same DO-214AC footprint; slightly higher thermal resistance requires marginally larger copper pour | Preferred where STMicroelectronics supply chain alignment is required |
| MBR260 | VRRM = 60V only; Schottky construction yields VF ≈ 0.75V but no 600V capability | Not suitable for 600V blocking; limited to low-voltage (<100V) DC-DC outputs | Only viable if system VRRM requirement is ≤60V and ultra-low VF is critical |
Compared with STTH2R06, ES2JA R3G offers lower thermal resistance for identical board area; versus MBR260, ES2JA R3G provides six times higher reverse voltage rating at the cost of higher forward drop - making it the sole valid option for 600V-class snubbers and flyback primaries.

FAQ
What is the maximum junction temperature rating for ES2JA R3G?
The ES2JA R3G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in Taiwan Semiconductor's M2102 datasheet. This allows operation in high-ambient environments such as enclosed industrial drives or LED luminaires, provided thermal design maintains TJ ≤ 150°C under worst-case load and ambient conditions. The ES2JA R3G's RθJA = 75°C/W enables this with appropriate PCB copper area.
Does ES2JA R3G meet RoHS and halogen-free requirements?
Yes, ES2JA R3G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the official Taiwan Semiconductor datasheet (Version M2102). The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm - satisfying both EU RoHS Directive 2011/65/EU and major OEM green material specifications.
What is the reverse recovery time (trr) test condition for ES2JA R3G?
The reverse recovery time of 35ns for ES2JA R3G is measured under the standardized condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, as specified in the "ELECTRICAL SPECIFICATIONS" table of the M2102 datasheet. This test reflects real-world switching behavior in hard-commutated topologies like flyback and forward converters, and the ES2JA R3G consistently meets this value across its qualified lot range.
Is ES2JA R3G suitable for use in automotive-grade power supplies?
ES2JA R3G is not AEC-Q101 qualified and is not recommended for automotive powertrain or safety-critical applications. While it operates reliably from –55°C to +150°C and meets J-STD-020 level 1 moisture sensitivity, Taiwan Semiconductor does not specify automotive qualification testing for the ES2JA R3G. For automotive use, designers should select AEC-Q101-certified alternatives unless the application is non-safety-related and fully validated per OEM requirements.
What packaging format is available for ES2JA R3G?
ES2JA R3G is supplied in 7,500-piece tape-and-reel packaging per the "ORDERING INFORMATION" section of the M2102 datasheet, using standard DO-214AC (SMA) carrier tape compatible with all major SMT pick-and-place equipment. The reel conforms to EIA-481-D standards, and the device marking code "ES2JA" is laser-etched on the cathode-band side for automated optical inspection compatibility.
