Product details
Overview
ES2D-T from Taiwan Semiconductor is a 2 A, 200 V super fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 0.95 V max forward voltage at 2 A, and 50 A surge current capability - used in high-frequency DC/DC converters and switching inverters.
For engineers reviewing the ES2D-T datasheet, ES2D-T pinout, ES2D-T application, or ES2D-T 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-T employs a single-die, glass-passivated PN junction optimized for super-fast recovery (trr ≤ 35 ns), enabling efficient operation in high-frequency switching topologies. Its low forward voltage (VF ≤ 0.95 V @ 2 A, 25 °C) and low junction capacitance (CJ = 25 pF @ 1 MHz, 4 V) reduce conduction and switching losses.
Designed for surface-mount assembly with matte tin-plated leads (J-STD-002 compliant) and moisture sensitivity level 1 (J-STD-020), the ES2D-T supports automated placement and reflow soldering without derating. Polarity is marked by a cathode band on the DO-214AA molded body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 2 A - continuous forward current rating defines maximum steady-state power handling in rectification paths |
| VRRM | 200 V - peak reverse blocking voltage determines maximum AC input or flyback voltage it can safely withstand |
| trr | 35 ns - ultra-fast reverse recovery minimizes switching loss and EMI in >100 kHz SMPS designs |
| VF (max) | 0.95 V @ 2 A - low forward drop reduces conduction loss and thermal stress under full load |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance enables direct PCB copper pad heat sinking without heatsink |
| IR (max) | 10 µA @ 25 °C - low leakage ensures stable DC bus hold-up and minimal standby power loss |
Pinout & Package
Package: DO-214AA (SMB) - standardized surface-mount plastic package with cathode-indicated band, 0.090 g weight, UL 94V-0 rated molding compound, and JESD201 Class 1A whisker-resistant matte tin leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 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 | Marked by band; connects to output rail or capacitor positive; blocks 200 V reverse voltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in unsealed industrial environments |
| Super fast trr ≤ 35 ns | Enables use in 200–500 kHz DC/DC converters without snubber circuits or efficiency penalty |
| Moisture sensitivity level 1 | Eliminates bake requirement before reflow, reducing manufacturing cost and process complexity |

Applications
| DC/DC Converter Primary Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: High-efficiency isolated buck-boost converter operating at 250 kHz in telecom power supply. IC Role / Device Role / Timing Role: Output rectifier conducting 2 A average current with minimal VF-related loss and fast trr to suppress ringing. Use Value: 0.95 V VF and 35 ns trr directly reduce total power loss by ≥12% vs. standard fast recovery diodes in same layout. | Use Scenario: IGBT-based motor drive inverter leg with inductive load commutation. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT turn-off. Use Value: 50 A IFSM and 200 V VRRM ensure robust protection against transient overcurrents up to 8.3 ms half-sine surges. |

IC Role / Device Role / Timing Role: Output rectifier in high-frequency resonant LLC stage delivering regulated DC. Use Value: 10 µA IR at 25 °C prevents measurable current drift in precision current-sense feedback loop over temperature. |
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-ES2D-M3/5BT | Same DO-214AA package, identical 200 V VRRM and 2 A IF, but trr = 30 ns (5 ns faster), VF = 0.93 V max | Suitable for margin-critical 500 kHz+ designs where sub-35 ns trr improves EMI profile | Select when tighter trr tolerance or slightly lower VF justifies dual-source qualification |
| ON Semiconductor MUR220T3G | DO-214AC (SMA) package (smaller footprint), 200 V VRRM, 2 A IF, trr = 35 ns, VF = 0.92 V max, but RθJA = 100 °C/W (vs. 75 °C/W for ES2D-T) | Better for space-constrained boards; requires more careful thermal layout due to higher ambient thermal resistance | Prefer for compact designs where board area is limiting and thermal management is enhanced via copper fill |
Compared with VS-ES2D-M3/5BT and MUR220T3G, the ES2D-T offers balanced performance with industry-standard DO-214AA mechanical compatibility, superior thermal resistance (RθJL = 20 °C/W), and proven reliability in high-volume industrial power supplies - making it optimal for cost-sensitive, thermally demanding, and production-stable applications.

FAQ
What is the maximum junction temperature rating for the ES2D-T?
The ES2D-T has a maximum junction temperature (TJ) rating of +150 °C, with an operational range from –55 °C to +150 °C. This allows reliable operation in enclosed industrial enclosures or near heat-generating components. Derating curves in the ES2D-T datasheet specify usable current versus lead temperature, supporting thermal design validation without additional simulation.
Does the ES2D-T support lead-free reflow soldering per JEDEC J-STD-020?
Yes, the ES2D-T is qualified for lead-free reflow soldering and carries moisture sensitivity level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. Its matte tin-plated leads meet J-STD-002 for solderability, and the DO-214AA package withstands peak reflow temperatures up to 260 °C for 10 seconds.
What is the reverse recovery time (trr) test condition for the ES2D-T?
The ES2D-T reverse recovery time is measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per standard test circuit Figure 6 in the ES2D-T datasheet. The specified maximum trr is 35 ns under these conditions, confirming its classification as a super fast rectifier suitable for high-frequency switching applications.
Is the ES2D-T halogen-free and RoHS compliant?
Yes, the ES2D-T is both RoHS compliant and halogen-free, as confirmed in the official Taiwan Semiconductor product documentation (Version D2305). The molding compound contains no brominated flame retardants or chlorine-based additives, meeting IEC 61249-2-21 and JEDEC JS709C requirements for environmentally restricted substances.
How is polarity indicated on the ES2D-T package?
Polarity on the ES2D-T is indicated by a distinct cathode band printed on the DO-214AA (SMB) molded body - located at the cathode end of the device. This band aligns with the cathode terminal, which must be connected to the higher-potential node in forward-biased operation. The marking code "ES2D" appears adjacent to the band per the official package outline drawing.
