Product details
Overview
ES2DA-T from Taiwan Semiconductor is a 2 A, 200 V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.91 V forward voltage at 2 A/25°C, and 5 µA max reverse leakage at 25°C. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES2DA-T datasheet, ES2DA-T pinout, ES2DA-T application, or ES2DA-T equivalent, key selection criteria include its 200 V VRRM, low VF at elevated current, thermal resistance of 14 °C/W (junction-to-lead), and compatibility with automated SMT assembly per J-STD-020 Level 1 moisture sensitivity.
Technical Context
This device is a single-die, silicon planar junction rectifier with glass passivated chip construction, optimized for high-speed switching operation. Its 35 ns reverse recovery time and 26 pF junction capacitance at 4 V enable efficient performance in DC–DC converters operating up to several hundred kHz.
The ES2DA-T operates across –55°C to +150°C junction temperature range and delivers 2 A average forward current with derating above 75°C ambient. Thermal design is supported by verified RθJL = 14 °C/W on 5 mm × 5 mm Cu pad PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; defines safe operating ceiling in flyback or boost topologies. |
| IF | 2 A - Continuous average forward current rating at TA = 75°C; supports compact 2 A power rail rectification. |
| trr | 35 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency switching with low switching loss. |
| VF @ 2 A, 25°C | 0.91 V - Forward voltage drop at rated current; directly determines conduction loss and thermal load in continuous operation. |
| IR @ VRRM, 25°C | 5 µA max - Low reverse leakage ensures minimal standby power loss in offline SMPS and battery-isolated circuits. |
| CJ @ 4 V, 1 MHz | 26 pF - Junction capacitance affects high-frequency noise coupling and snubber design in resonant converters. |
| RθJL | 14 °C/W - Junction-to-lead thermal resistance measured on standard PCB; enables accurate thermal modeling for board-level heatsinking. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration. Cathode identified by molded band. Matte tin-plated leads, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| DC–DC Converter | Switching Mode Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 12 V → 3.3 V/5 V flyback or forward converters. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC from transformer secondary to regulated DC. Use Value: 0.91 V VF at 2 A reduces conduction loss vs. standard FR diodes, improving efficiency by ~0.8% at full load. | Use Scenario: Freewheeling path in H-bridge motor drive inverters for HVAC blowers or industrial pumps. IC Role / Device Role / Timing Role: Clamp inductive kickback during MOSFET turn-off; conducts only during dead-time intervals. Use Value: 35 ns trr minimizes cross-conduction risk and EMI generation during rapid polarity reversal. |
| AC–DC Adapter | Industrial Power Supply |
Use Scenario: Output rectification in compact 24 W USB-C PD adapters with active clamp flyback topology. IC Role / Device Role / Timing Role: Primary output rectifier delivering 3 A peak current pulses at 100–200 kHz switching frequency. Use Value: 26 pF CJ limits capacitive coupling noise into feedback loop, easing EMI filter design. | Use Scenario: Auxiliary bias supply rectification in programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Isolated 15 V/100 mA auxiliary rail rectifier powered from main transformer auxiliary winding. Use Value: –55°C to +150°C TJ range ensures uninterrupted operation in uncooled control cabinets exposed to wide ambient swings. |
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 (STMicroelectronics) | Same 200 V VRRM, 2 A IF, but trr = 30 ns and VF = 0.95 V @ 2 A/25°C; DO-214AC package. | Slightly faster recovery supports marginally higher switching frequencies; higher VF increases conduction loss by ~45 mW at 2 A. | Prefer when trr-critical timing dominates over thermal budget in ultra-high-frequency designs. |
| MBR220 (ON Semiconductor) | 200 V Schottky rectifier; VF = 0.52 V @ 2 A/25°C, but IR = 100 µA @ 25°C and TJmax = 125°C. | Lower forward loss improves light-load efficiency, but higher leakage and lower temperature rating limit use in high-ambient or high-reliability systems. | Select only where ambient stays below 60°C and reverse leakage is non-critical (e.g., non-isolated buck converters). |
Compared with STTH2R02U and MBR220, the ES2DA-T offers the best balance of low VF, ultra-low IR, and extended temperature capability-making it optimal for industrial and telecom power supplies requiring robustness across full thermal and electrical stress profiles.

FAQ
What is the maximum junction temperature rating for the ES2DA-T?
The ES2DA-T has a maximum junction temperature (TJ) rating of +150°C, with operational range spanning –55°C to +150°C. This allows reliable deployment in sealed enclosures or high-ambient environments such as industrial control panels. Derating curves in the official datasheet specify allowable IF reduction above 75°C ambient, and thermal design must account for RθJL = 14 °C/W on standard 5 mm × 5 mm copper pads. The ES2DA-T maintains full specification compliance across this full range when properly mounted.
Does the ES2DA-T have a specified reverse recovery time, and how is it measured?
Yes, the ES2DA-T has a specified reverse recovery time (trr) of 35 ns maximum, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss and EMI in high-frequency topologies. The test uses pulse conditions defined in JEDEC standards, and the ES2DA-T's trr is validated across temperature and current ranges documented in the TSC D2111 datasheet revision.
Is the ES2DA-T compatible with lead-free reflow soldering processes?
Yes, the ES2DA-T features matte tin-plated leads compliant with J-STD-002 for solderability and is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its moisture sensitivity level is rated Class 1, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard Pb-free reflow profiles (peak 260°C) without baking. The DO-214AC package body meets UL 94V-0 flammability requirements, supporting process compatibility and end-equipment safety certification.
How does the forward voltage of the ES2DA-T vary with temperature and current?
The ES2DA-T exhibits negative temperature coefficient for forward voltage: VF decreases as junction temperature rises-e.g., from 0.91 V at 2 A/25°C to 0.78 V at 2 A/125°C. This behavior reduces conduction loss at elevated temperatures but requires thermal-aware layout to avoid thermal runaway in parallel configurations. The datasheet provides full VF vs. IF and TJ curves (Fig.4 and Fig.6), confirming stable operation across its rated range. Designers should reference these curves-not just room-temperature values-when calculating worst-case losses.
What packaging and reel quantity is offered for the ES2DA-T?
The ES2DA-T is supplied in DO-214AC (SMA) package on 7,500-unit tape-and-reel format, per the official ordering code ES2xA-T (where "x" = D for 200 V). Reels comply with EIA-481 standards and are compatible with standard SMT pick-and-place equipment. Each reel includes traceable lot coding per TSC's quality system, and packaging documentation confirms J-STD-020 Level 1 moisture sensitivity-enabling immediate placement without dry-pack intervention. Aetrix Electronics stocks full reels and offers cut-tape options for prototyping.
