Product details
Overview
ES2JAHR3G 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 ES2JAHR3G datasheet, ES2JAHR3G pinout, ES2JAHR3G application, or ES2JAHR3G 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 single-die silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. 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), enabling minimal switching loss in high-frequency snubber networks. Reverse leakage remains ≤350µA at 125°C, supporting reliable operation in thermally demanding industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines upper limit for use in 400V DC bus systems with safety margin |
| IF | 2 A - Continuous average forward current; supports sustained conduction in 24–48V output DC-DC stages |
| trr | 35 ns - Measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables >200kHz switching without excessive turn-off loss |
| VF (max) | 1.70 V @ 2A, 25°C - Directly impacts conduction loss and thermal rise in compact power layouts |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; determines heatsinking requirements on standard FR-4 PCB with 1in² copper pour |
| IFSM | 50 A - Non-repetitive peak surge rating; withstands inrush during cold-start of SMPS with bulk capacitors |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case meeting UL 94V-0, matte tin-plated leads compliant with J-STD-002 solderability, 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 higher-potential rail (e.g., output capacitor positive); critical for snubber placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in non-condensing environments |
| Super fast 35ns recovery | Reduces switching loss by >40% vs. standard rectifiers in 100–500kHz converters, improving efficiency by 0.8–1.5% |
| DO-214AC (SMA) package | Enables automated pick-and-place at >15,000 UPH; compatible with IPC-7351B footprint for seamless board integration |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; supports standard JEDEC J-STD-020 handling without dry pack or MSL management |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters delivering 12–48V outputs. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; handles 2A continuous current with minimal VF-induced loss.

IC Role / Device Role / Timing Role: Snubber diode clamping voltage spikes across IGBTs during turn-off transitions. Use Value: 35ns trr ensures clean clamping without oscillation, preventing false triggering of overvoltage protection. |
| LED Driver | Industrial Power Supply |
Use Scenario: Constant-current regulation loop in offline LED drivers using buck-boost topology. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC from transformer secondary to regulated DC for LED strings. Use Value: 600V VRRM accommodates line-voltage transients up to 450VAC, meeting IEC 61347-2-13 surge immunity. | Use Scenario: Auxiliary bias supply in programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Input rectifier feeding 24V DC-DC stage from 24–48V DC input rails with transient tolerance. Use Value: 50A IFSM sustains repeated cold-start surges without degradation, ensuring field reliability over 10-year service life. |
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 | VF = 1.75V (max), trr = 30ns, same DO-214AC package | Slightly faster recovery but higher forward drop; better for ultra-high-frequency designs where turn-off loss dominates | Prefer when optimizing for <100ns transition times in resonant topologies |
| MBR260 | Schottky type, VF = 0.72V (typ), VRRM = 60V only, same IF | Lower conduction loss but insufficient for 600V blocking; limited to low-voltage DC-DC outputs | Select only for secondary-side rectification below 100V; not suitable as direct replacement for ES2JAHR3G |
Compared with STTH2R06 and MBR260, ES2JAHR3G delivers optimal balance of 600V blocking, 35ns recovery, and 1.70V VF for primary-side and mid-voltage auxiliary rectification-making it uniquely suited for universal-input industrial SMPS where both voltage headroom and switching efficiency matter.

FAQ
What is the maximum junction temperature rating for ES2JAHR3G?
The ES2JAHR3G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in enclosed industrial enclosures with ambient temperatures up to +85°C when mounted on standard FR-4 PCB with 1in² copper pour. Derating begins at 25°C ambient per Fig.1 in the datasheet.
Does ES2JAHR3G meet RoHS and halogen-free requirements?
Yes, ES2JAHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. Full compliance documentation is available upon request from Taiwan Semiconductor's quality portal.
What is the reverse recovery time test condition for ES2JAHR3G?
The reverse recovery time (trr) of 35ns for ES2JAHR3G is measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, with specified pulse waveform per JEDEC JESD24-10. This value is guaranteed maximum and applies across the full -55°C to +125°C operating junction temperature range.
Is ES2JAHR3G suitable for use in automotive applications?
No, ES2JAHR3G is not qualified to AEC-Q101 or automotive-grade reliability standards. Taiwan Semiconductor explicitly states these devices are not designed for medical, life-saving, or life-sustaining applications-including automotive safety-critical systems. Use only in industrial, commercial, or lighting equipment.
What does the 'HR3G' suffix indicate in ES2JAHR3G?
The 'HR3G' suffix denotes Taiwan Semiconductor's tape-and-reel packaging: H = halogen-free, R3 = 7,500 units per reel, G = green compound (RoHS-compliant epoxy). This matches the ordering code ES2JA in DO-214AC (SMA) package with standard MSL-1 handling per J-STD-020.
