Product details
Overview
ES2D from Taiwan Semiconductor is a 2 A, 200 V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and 10 µA reverse leakage at 25°C, used in DC-DC converters and snubber circuits.
For engineers reviewing the ES2D datasheet, ES2D pinout, ES2D application, or ES2D equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The ES2D operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its super fast recovery enables high-frequency switching in SMPS topologies without excessive switching loss.
Designed for automated SMT assembly, the DO-214AA (SMB) package supports reflow soldering per J-STD-002, with matte tin-plated leads and UL 94V-0 molding compound. Polarity is marked by cathode band; weight is 0.090 g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or boost converter output stages |
| IF | 2 A - Continuous average forward current; determines thermal sizing of PCB copper and heatsinking in 100 kHz+ DC-DC designs |
| trr | 35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz with minimal switching loss and EMI generation |
| VF | 0.95 V @ 2 A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal rise in high-duty-cycle freewheeling paths |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to copper pour or metal-core PCB for passive cooling |
| IFSM | 50 A @ 8.3 ms - Non-repetitive surge rating; withstands inrush and transient overloads in lighting ballasts and motor drives |
| CJ | 25 pF @ 1 MHz, 4 V - Junction capacitance; influences high-frequency noise coupling and snubber design in resonant converters |
Pinout & Package
DO-214AA (SMB) surface-mount package: cathode-indicated band on body; anode and cathode terminals only; no internal connections beyond diode junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate trace width for 2 A continuous |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or snubber network; polarity marking critical for correct orientation during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term performance under humid conditions and prevents junction corrosion in industrial environments |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) and associated switching losses in high-frequency SMPS above 200 kHz |
| Moisture sensitivity level 1 | Eliminates bake requirement before reflow; compatible with standard SMT lines without dry-pack handling |
| Halogen-free (IEC 61249-2-21) | Meets environmental compliance for automotive and EU industrial equipment without compromising flame retardancy (UL 94V-0) |
| Low profile SMB package | Height ≤ 2.6 mm enables compact layout in space-constrained LED drivers and AC-DC adapters |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/2 A flyback converter powering industrial I/O modules. IC Role / Device Role / Timing Role: Unidirectional power conversion element conducting during transformer reset phase; replaces slower 1N5822 to reduce switching loss. Use Value: 35 ns trr cuts reverse recovery loss by >40% vs. standard fast rectifiers, improving efficiency from 82% to 85.3% at full load. | Use Scenario: RCD clamp across MOSFET drain-source in 65 kHz PFC boost stage. IC Role / Device Role / Timing Role: Fast recovery diode capturing energy from leakage inductance; must turn off rapidly before next switching cycle. Use Value: 25 pF CJ and 35 ns trr minimize voltage overshoot and ringing, reducing stress on 600 V MOSFET. |
| Lighting Application | Freewheeling Application |
Use Scenario: Output rectifier in constant-current LED driver for streetlight luminaires (input 90–305 VAC). IC Role / Device Role / Timing Role: High-reliability rectifier handling 2 A continuous output with thermal cycling from ambient –40°C to +85°C. Use Value: 150°C TJMAX and J-STD-020 Level 1 allow uninterrupted operation in sealed outdoor enclosures without derating. | Use Scenario: Freewheeling path across solenoid coil in programmable logic controller (PLC) output module. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when 24 V DC coil is de-energized; suppresses inductive kick. Use Value: 0.95 V VF limits power dissipation to <1.9 W during 2 A freewheeling, avoiding thermal shutdown in dense PCB layouts. |
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-ES2D02-M3/5BT | Same VRRM (200 V), identical DO-214AA package, but trr = 30 ns (5 ns faster); VF = 0.92 V @ 2 A | Slightly lower conduction and switching loss; suitable where <5 ns trr reduction justifies cost premium | Preferred for high-efficiency 500 kHz+ resonant LLC designs requiring minimal Qrr |
| ON Semiconductor MUR220RLG | VRRM = 200 V, same IF, but DO-41 through-hole package; trr = 35 ns, VF = 0.97 V | Requires manual or wave-solder assembly; unsuitable for fully automated SMT production | Select only for legacy through-hole designs or prototyping where rework flexibility outweighs SMT efficiency |
Compared with VS-ES2D02-M3/5BT and MUR220RLG, the ES2D delivers optimal balance of SMT compatibility, thermal performance (RθJL = 20 °C/W), and cost for volume-manufactured industrial DC-DC and lighting systems.

FAQ
What is the maximum junction temperature rating for the ES2D?
The ES2D has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table in TSC's L2102 datasheet. This allows reliable operation in enclosed industrial environments where ambient temperatures reach +85°C and power dissipation generates additional thermal rise. The ES2D must be mounted on sufficient copper area to maintain TJ ≤ 150°C under worst-case IF = 2 A conditions.
Does the ES2D meet RoHS and halogen-free requirements?
Yes, the ES2D is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of TSC's official ES2A–ES2J datasheet (Version L2102). The molding compound is UL 94V-0 rated, and terminals are matte tin plated-fully compatible with lead-free reflow processes and environmentally regulated end equipment.
What is the reverse recovery time (trr) of the ES2D and how is it measured?
The ES2D has a reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in TSC's electrical characteristics table. This value is typical and guaranteed maximum; it reflects the diode's ability to transition from conduction to blocking state, directly impacting switching loss in high-frequency converters using the ES2D.
Can the ES2D replace the ES2C in an existing design?
Yes, the ES2D can replace the ES2C in most cases because both share identical package (DO-214AA), forward current (2 A), thermal specs, and pinout-but the ES2D has higher VRRM (200 V vs. 150 V) and slightly lower VF (0.95 V vs. 0.96 V). Review system-level reverse voltage stress to confirm 200 V margin is appropriate; no PCB or layout changes are needed for the ES2D substitution.
What is the junction-to-lead thermal resistance (RθJL) of the ES2D and why does it matter?
The ES2D has a junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from die to PCB copper via the cathode/anode leads. This parameter matters because it directly determines achievable power dissipation without exceeding TJMAX; for example, at 2 A and 0.95 V VF, the ES2D dissipates ~1.9 W, requiring ≤38°C temperature rise from lead to junction-achievable with ≥1 cm² of 2-oz copper connected to both terminals.
