Product details
Overview
ES2DAHR3G from Taiwan Semiconductor is a 2 A, 200 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and 50 A peak surge current - used in DC-DC converters and snubber circuits for high-frequency switching efficiency.
For engineers reviewing the ES2DAHR3G datasheet, ES2DAHR3G pinout, ES2DAHR3G application, or ES2DAHR3G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), junction-to-lead thermal resistance (20 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and DO-214AC mechanical compatibility with automated placement.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses, while the glass-passivated junction ensures stable performance under thermal cycling and humidity stress.
The DO-214AC (SMA) package provides low profile mounting, matte tin-plated leads compliant with J-STD-002 solderability, and UL 94V-0 molding compound - supporting reflow and wave soldering in industrial power supply assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in flyback or buck-derived topologies |
| IF | 2 A continuous - average forward current rating at TA = 25°C; derates linearly above 25°C per forward current derating curve |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables operation up to ~3–5 MHz in resonant or quasi-resonant converters |
| VF | 0.95 V @ 2 A, TJ = 25°C - low conduction loss improves system efficiency; increases to ~1.1 V at TJ = 125°C |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; supports direct PCB copper pad heat sinking for compact layout |
| IR | 10 µA @ VR = 200 V, TJ = 25°C - low leakage preserves hold-up energy in standby mode and reduces standby power loss |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with cathode band marking; matte tin-plated leads; weight ≈ 0.060 g; polarity indicated by cathode band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node in boost/flyback); must be routed with low-inductance path |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or clamp node; cathode band identifies this terminal visually and in layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability under humidity and thermal stress; eliminates need for conformal coating in IPC Class 2 environments |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) and associated switching losses in high-frequency SMPS designs |
| J-STD-020 Level 1 moisture sensitivity | Enables standard SMT assembly without baking; supports immediate use after dry pack opening |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance requirements for industrial and consumer end equipment |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 200 kHz–1 MHz flyback or forward converters powering telecom or embedded systems. IC Role / Device Role / Timing Role: Unidirectional current steering and voltage clamping during transformer reset phase. Use Value: 35 ns trr and 0.95 V VF reduce conduction + switching losses, improving full-load efficiency by ~0.8–1.2% vs. standard fast rectifiers. | Use Scenario: RCD snubber network across MOSFET drain-source in hard-switched PFC or LLC primary-side circuits. IC Role / Device Role / Timing Role: Fast turn-off to absorb voltage spikes during MOSFET turn-off transitions. Use Value: Low Qrr and tight trr distribution minimize snubber energy dissipation and thermal rise in high-repetition switching. |
| Lighting Driver | Freewheeling Diode |
Use Scenario: Output rectification in constant-current LED drivers operating at 50–200 kHz with PWM dimming. IC Role / Device Role / Timing Role: High-efficiency AC/DC conversion stage delivering regulated DC to LED string. Use Value: Low VF maintains stable current regulation across line variations; DO-214AC footprint fits compact LED module PCBs. | Use Scenario: Inductive load freewheeling path in solenoid, relay, or motor driver H-bridge outputs. IC Role / Device Role / Timing Role: Provides low-impedance return path for stored inductor energy during switch off-time. Use Value: 50 A IFSM withstands transient surges from inductive kickback; 200 V VRRM covers typical 24–48 V industrial bus voltages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02U | 2 A, 200 V, trr = 30 ns, VF = 0.92 V @ 2 A, DO-214AC, same MSL Level 1 | Slightly faster trr and lower VF; identical package and thermal specs | Preferred where <5 ns trr reduction improves EMI or efficiency margin in >500 kHz designs |
| MBR220LSFT1G | 2 A, 200 V Schottky, VF = 0.52 V @ 2 A, trr not applicable, TJ max = 125°C, DO-214AC | Lower VF but limited to ≤125°C junction; no reverse recovery, but higher IR at elevated temperature | Consider only if ambient temperature stays below 85°C and reverse leakage tolerance allows |
Compared with STTH2R02U and MBR220LSFT1G, ES2DAHR3G offers balanced trade-offs: robust 150°C TJ rating, proven reliability in humid environments via glass passivation, and cost-effective performance for industrial DC-DC and snubber use - without Schottky's thermal limitations or ultra-fast Si's tighter process control requirements.

FAQ
What is the maximum junction temperature rating for ES2DAHR3G?
The ES2DAHR3G has a maximum junction temperature (TJ) rating of +150°C, with storage temperature ranging from –55°C to +150°C. This rating enables operation in high-ambient industrial environments when mounted on adequate copper area. Thermal design must account for RθJL = 20 °C/W and RθJA = 75 °C/W to avoid exceeding TJ max under full load.
Does ES2DAHR3G have a specified reverse recovery time (trr)?
Yes, ES2DAHR3G has a maximum reverse recovery time (trr) of 35 ns, tested under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet Version M2102 and is critical for minimizing switching losses in high-frequency converter topologies.
Is ES2DAHR3G RoHS and halogen-free compliant?
Yes, ES2DAHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses environmentally compliant molding compound and matte tin-plated leads, satisfying regulatory requirements for industrial and consumer electronics sold in EU, China, and North America markets.
What package type does ES2DAHR3G use, and is it compatible with automated assembly?
ES2DAHR3G uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads solderable per J-STD-002. Its low-profile design and J-STD-020 Level 1 moisture sensitivity make it fully compatible with standard pick-and-place and reflow processes without pre-baking.
How does the forward voltage (VF) of ES2DAHR3G vary with temperature and current?
ES2DAHR3G exhibits VF = 0.95 V at IF = 2 A and TJ = 25°C, rising to approximately 1.1 V at TJ = 125°C under same current. The device follows typical silicon diode VF vs. temperature behavior: VF decreases slightly with increasing temperature at fixed current, but overall conduction loss increases due to higher IR²R contribution at elevated junction temperatures.
