Product details
Overview
ES3DB from Taiwan Semiconductor is a 3A, 200V super fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3.0A/25°C, and 100A surge current capability - deployed in high-frequency switching power supplies and LED lighting converters.
For engineers reviewing the ES3DB datasheet, ES3DB pinout, ES3DB application, or ES3DB equivalent, key selection criteria include its 200V VRRM, low VF at elevated temperature (0.73V @ 3A/125°C), junction-to-lead thermal resistance of 24°C/W, and RoHS/halogen-free compliance for industrial-grade SMPS designs.
Technical Context
The ES3DB is a single-die, glass-passivated silicon PN junction rectifier optimized for high-efficiency switching applications. Its super-fast recovery (trr ≤ 35ns) minimizes switching losses in 50–500kHz converters, while the DO-214AA package enables automated placement and meets J-STD-020 moisture sensitivity level 1.
Thermal performance is defined with 10mm × 10mm copper pad PCB mounting: RθJL = 24°C/W ensures effective heat transfer to the PCB lead frame, and TJ rating of –55°C to +150°C supports operation in thermally constrained environments such as enclosed LED drivers and compact adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; sets upper limit for DC bus or clamp voltage in flyback/foward converters |
| IF | 3 A - Continuous forward current rating; defines steady-state conduction capacity at TA = 25°C with derating above 75°C |
| IFSM | 100 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and transient overloads in AC-DC inputs |
| trr | ≤ 35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz without excessive switching loss or EMI |
| VF @ 3A/25°C | 0.86 V - Forward voltage drop; directly impacts conduction loss and thermal design in high-duty-cycle topologies |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance; determines temperature rise from die to solder joint under PCB-mounted conditions |
| CJ @ 1MHz/4V | 46 pF - Junction capacitance; influences high-frequency noise coupling and snubber design in resonant circuits |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band.

|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or filter capacitor positive; cathode band marks this terminal physically |
Key Features
| Feature | Design Value |

| Super fast recovery (≤35ns) | Reduces reverse recovery charge (Qrr) and associated switching loss - measurable efficiency gain in 200–500kHz SMPS |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without process modification |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance mandates for consumer, industrial, and commercial end equipment |
| DO-214AA mechanical robustness | Withstands >10g vibration and thermal cycling per JESD22-A108; suitable for non-hermetic, high-volume power modules |
Applications
| LED Lighting Driver | USB-C PD Adapter Output Rectification |
|---|---|
Use Scenario: Secondary-side rectification in constant-current LED drivers operating at 100–300kHz. IC Role / Device Role / Timing Role: High-efficiency unidirectional current path replacing slower FR/UF diodes to reduce heat and improve lumen maintenance. Use Value: 0.73V VF @ 3A/125°C lowers conduction loss by ~12% vs. legacy 1N5822, extending thermal margin in sealed luminaires. | Use Scenario: Output synchronous rectification replacement in 30–65W USB-C power adapters with active clamp or QR flyback. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode handling 3A continuous output current with minimal reverse recovery ringing. Use Value: 35ns trr suppresses high-frequency EMI spikes near 100MHz, easing EMC filter design and reducing common-mode noise. |

Use Scenario: Input rectification in 24V/48V isolated DC-DC modules for PLC I/O and sensor interfaces. IC Role / Device Role / Timing Role: Primary rectifier converting 100–240VAC-derived DC bus to intermediate rail; operates continuously at 75°C ambient. Use Value: RθJL = 24°C/W enables stable 150°C junction temperature with only 10mm×10mm Cu pad - no heatsink required. | Use Scenario: Standby supply rectification in main AC-DC power supplies powering microcontrollers and communication ICs. IC Role / Device Role / Timing Role: Low-leakage (≤10µA @ 25°C) and low-VF rectifier delivering 3A peak during wake-up events. Use Value: 0.86V VF at 3A reduces standby power dissipation by 0.26W vs. 1N5822, improving no-load efficiency by 0.4%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH02-M3/45 | Same DO-214AA package; 200V VRRM, 35ns trr, but higher VF = 0.92V @ 3A/25°C | Slightly higher conduction loss; less optimal for thermally tight LED drivers | Preferred where Vishay supply chain alignment or qualification history is required |
| ON Semiconductor MUR320RLG | DO-201AD (axial) package; 200V VRRM, 35ns trr, VF = 0.95V @ 3A/25°C; not SMT-compatible | Requires through-hole assembly; unsuitable for high-density SMT layouts | Only viable if board redesign for axial footprint is acceptable |
Compared with VS-3EYH02-M3/45 and MUR320RLG, the ES3DB delivers the lowest forward voltage in its class among DO-214AA-packaged 200V super fast rectifiers - yielding superior thermal performance and efficiency in space-constrained SMT power stages.

FAQ
What is the maximum junction temperature rating for the ES3DB?
The ES3DB has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed LED drivers and industrial converters where ambient temperatures exceed 75°C, provided thermal design respects the RθJL = 24°C/W specification on a 10mm × 10mm Cu pad.
Does the ES3DB have a specified reverse recovery time, and how is it measured?
Yes, the ES3DB has a reverse recovery time (trr) of ≤35ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table and reflects performance at room temperature; trr remains stable across the full operating junction temperature range.
What is the forward voltage of the ES3DB at 3A and 125°C junction temperature?
The ES3DB exhibits a forward voltage (VF) of 0.73V at 3.0A and 125°C junction temperature. This low VF at elevated temperature directly reduces conduction losses and improves thermal headroom compared to standard Schottky or general-purpose rectifiers in high-ambient applications.
Is the ES3DB compliant with RoHS and halogen-free standards?
Yes, the ES3DB is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and plating meet UL 94V-0 flammability requirements, and the device carries no restricted substances above threshold limits - verified in TSC's official compliance documentation for version C2102.
What packaging and reel quantity is offered for the ES3DB?
The ES3DB is supplied in DO-214AA (SMB) package on tape-and-reel format, with 3,000 units per reel. This configuration supports high-speed automated placement and is compatible with standard SMT pick-and-place equipment using industry-standard feeders and vision systems.
