Product details
Overview
ES2DV from Taiwan Semiconductor is a 2A, 200V ultra-fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, designed for high-frequency switching applications including SMPS, adapters, and display power supplies. It features 20 ns reverse recovery time, 0.9 V max forward voltage at 2 A, and 50 A surge current capability.
For engineers reviewing the ES2DV datasheet, ES2DV pinout, ES2DV application, or ES2DV equivalent, key selection criteria include its ultra-fast trr (20 ns), low VF (≤0.9 V @ 2 A), J-STD-020 Level 1 moisture sensitivity, RoHS/halogen-free compliance, and SMB package thermal performance (RθJA = 75 °C/W).
Technical Context
The ES2DV is a single-die, silicon planar junction rectifier with glass passivated chip construction, enabling stable operation up to 150 °C junction temperature. Its ultra-fast recovery (trr ≤ 20 ns) minimizes switching losses in high-frequency converters operating above 50 kHz.
Designed for automated SMT placement, the device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AA (SMB) body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines safe blocking capability in AC/DC front-end and flyback clamp circuits. |
| IF | 2 A - Continuous average forward current; supports compact 20–30 W adapter and monitor auxiliary supply designs. |
| trr | 20 ns - Ultra-fast reverse recovery time; reduces switching loss and EMI in 100–500 kHz SMPS topologies. |
| VF (max) | 0.9 V @ 2 A, 25°C - Low conduction loss; improves efficiency and thermal margin vs. standard fast rectifiers. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; enables PCB-level thermal design without heatsink in low-power applications. |
| IFSM | 50 A - Non-repetitive surge rating; withstands inrush and transient overloads in AC input stages. |
| IR (max) | 10 μA @ 25°C, 350 μA @ 150°C - Low leakage ensures stable DC bus hold-up and reduced standby loss. |
Pinout & Package

Applications
| SMPS Secondary Rectification | AC-DC Adapter Output Stage |
|---|---|
Use Scenario: High-efficiency 24–48 W offline flyback converter delivering regulated 5 V/12 V output. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer secondary AC to DC; operates at 65–130 kHz switching frequency. Use Value: 20 ns trr and 0.9 V VF reduce conduction + switching losses, improving full-load efficiency by ≥0.8% vs. standard fast diodes. | Use Scenario: Compact wall-mounted USB-C PD adapter with dual-output (5 V/3 A, 9 V/2.2 A) using active-clamp flyback. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in cost-sensitive designs where MOSFET control complexity is avoided. Use Value: SMB footprint and Level 1 MSL enable direct integration into dense, reflow-only layouts without moisture bake delays. |
| Monitor Power Supply | TV Standby & Auxiliary Rail |
Use Scenario: 19-inch LCD monitor with integrated 12 V/1 A main rail and 5 V/0.5 A logic rail powered from single flyback transformer. IC Role / Device Role / Timing Role: Primary output rectifier handling continuous 1.2 A load with intermittent 2 A peaks during backlight ramp-up. Use Value: 150 °C TJ max and 75 °C/W RθJA allow reliable operation on minimal 1 oz copper without thermal vias. | Use Scenario: Smart TV auxiliary power stage supplying 3.3 V/0.3 A always-on circuitry (remote receiver, RTC, network wake-up). IC Role / Device Role / Timing Role: Low-leakage (≤10 μA @ 25°C) rectifier maintaining stable 3.3 V rail during extended standby (>1 year). Use Value: Sub-μA leakage at elevated temperature ensures <5 mW no-load consumption, meeting Energy Star Tier 2 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | Same 2 A / 200 V rating; trr = 25 ns (5 ns slower); VF = 0.95 V max; DO-214AA package. | Slightly higher conduction loss and longer recovery increase EMI filtering burden in >200 kHz designs. | Acceptable for cost-sensitive 65–100 kHz adapters where 5 ns trr margin is non-critical. |
| SS220 | 2 A / 200 V Schottky; VF = 0.55 V typ but VR = only 20 V; not a voltage-compatible alternative. | Cannot replace ES2DV in 200 V blocking applications; limited to low-VF, low-voltage (<30 V) outputs. | Only suitable where system topology allows lower reverse voltage - not a functional substitute for ES2DV's 200 V rating. |
Compared with STTH2R02DJF and SS220, the ES2DV delivers superior trr (20 ns) and full 200 V blocking in a standard SMB footprint, making it optimal for high-frequency, high-reliability 20–50 W SMPS where leakage, thermal robustness, and RoHS/halogen-free compliance are mandatory.

FAQ
What is the maximum junction temperature rating for the ES2DV?
The ES2DV has a maximum junction temperature (TJ) rating of +150 °C, with a minimum of –55 °C. This wide operating range supports use in thermally demanding environments such as enclosed monitor or TV power supplies. The device's RθJA of 75 °C/W and RθJL of 25 °C/W allow accurate thermal modeling when designing PCB copper area and layout. Derating curves in the ES2DV datasheet confirm sustained 2 A operation up to 100 °C ambient with standard 1 oz copper.
Is the ES2DV compatible with lead-free reflow soldering processes?
Yes, the ES2DV is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its DO-214AA (SMB) package is rated for peak reflow temperatures up to 260 °C per JEDEC J-STD-020. With J-STD-020 Level 1 moisture sensitivity, the ES2DV does not require baking before reflow - enabling direct placement into standard SMT lines without process modification.
What does the "ES2DV" marking code indicate on the device body?
The "ES2DV" marking code printed on the cathode band side of the ES2DV identifies the exact device variant per Taiwan Semiconductor's ordering nomenclature. It confirms the 2 A / 200 V ultra-fast rectifier specification, DO-214AA (SMB) package, and green molding compound (per marking diagram). This code is used for traceability, counterfeit detection, and alignment with the official ES2DV datasheet revision C2102.
How does the ES2DV's reverse recovery time compare to standard fast rectifiers?
The ES2DV achieves a typical reverse recovery time (trr) of 20 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions - significantly faster than standard fast rectifiers (typically 50–100 ns). This ultra-fast trr reduces switching losses and EMI generation in high-frequency SMPS, especially above 100 kHz. The ES2DV's trr consistency across temperature and current ensures predictable performance in dynamic load scenarios encountered in adapters and monitors.
Can the ES2DV be used as a direct replacement for the ES1D or ES3D in existing designs?
No - the ES2DV is not a direct replacement for ES1D (1 A / 200 V) or ES3D (3 A / 200 V), due to differences in forward current rating and thermal performance. While all three share the DO-214AA package and 200 V VRRM, the ES2DV's 2 A IF and 50 A IFSM sit between them. Substituting requires verifying thermal margin (RθJA = 75 °C/W), layout copper, and peak current demands. Use ES2DV only where 2 A continuous rating is explicitly required and validated.
