Product details
Overview
ES1DV from Taiwan Semiconductor is a 1 A, 200 V ultra-fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 15 ns reverse recovery time, 0.92 V forward voltage at 1 A, and 30 A non-repetitive surge capability - used in DC/DC converters and snubber circuits for high-frequency switching efficiency.
For engineers reviewing the ES1DV datasheet, ES1DV pinout, ES1DV application, or ES1DV equivalent, key selection criteria include ultra-fast trr (≤15 ns), low VF (≤0.92 V @ 1 A), thermal resistance RθJA = 85 °C/W, RoHS/halogen-free compliance, and DO-214AC mechanical compatibility with automated SMT placement.
Technical Context
The ES1DV is a single-die, silicon planar junction rectifier optimized for high-frequency switching applications. Its ultra-fast recovery (trr ≤15 ns) minimizes switching losses in SMPS topologies, while glass passivation ensures stable junction performance under thermal cycling and humidity exposure.
Designed for surface-mount assembly, the device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band, and moisture sensitivity is rated Level 1 per J-STD-020 - eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage the device blocks without breakdown in normal operation |
| IF | 1 A - continuous average forward current rating at TA = 75°C with PCB heatsinking |
| trr | 15 ns - ultra-fast reverse recovery time enabling efficient operation up to ~1 MHz switching frequencies |
| VF | 0.92 V @ 1 A, 25°C - low forward voltage drop reduces conduction loss and thermal load in power stages |
| RθJA | 85 °C/W - junction-to-ambient thermal resistance defines required PCB copper area for thermal management |
| IFSM | 30 A - peak non-repetitive surge current handling capability during startup or fault transients |
| CJ | 17 pF @ 4 V - low junction capacitance minimizes displacement current and EMI in high-dV/dt environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | VRRM = 200 V, IF = 1 A, trr = 35 ns - slower recovery than ES1DV's 15 ns | Higher switching loss in >300 kHz designs; suitable for lower-frequency SMPS | Select when trr < 20 ns is not required and legacy qualification exists |
| Vishay VS-1EWH02-M3 | VRRM = 200 V, IF = 1 A, trr = 25 ns, VF = 0.95 V - slightly higher VF and trr vs. ES1DV | Marginally lower efficiency in high-density DC/DC modules | Prefer when dual-sourcing from Vishay-qualified supply chain is mandated |
Compared with MUR120 and VS-1EWH02-M3, the ES1DV delivers the fastest trr (15 ns) and lowest VF (0.92 V) in its class, making it optimal for compact, high-efficiency 1 A power stages where thermal headroom and switching loss are critical.

FAQ
What is the maximum junction temperature rating for the ES1DV?
The ES1DV has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in thermally demanding environments such as enclosed LED drivers or automotive under-hood modules. Derating curves in the ES1DV datasheet define safe average current versus ambient temperature and PCB copper area.
Does the ES1DV have a specified reverse recovery charge (Qrr)?
The ES1DV datasheet does not list Qrr directly, but Qrr can be estimated using trr = 15 ns, IF = 0.5 A, and Irr = 0.25 A per test conditions. Typical Qrr is <15 nC. For precise Qrr-dependent loss modeling in high-frequency designs, engineers should validate using bench measurements or SPICE models derived from ES1DV's published trr and CJ parameters.
Is the ES1DV suitable for use in automotive applications?
The ES1DV is not AEC-Q101 qualified and is not recommended for safety-critical automotive systems. However, it may be used in non-safety automotive auxiliary functions - such as interior lighting or infotainment power supplies - provided thermal derating, board layout, and system-level validation confirm reliability under real-world temperature and vibration conditions per the ES1DV's TJ = 150°C and storage specs.
What is the marking code printed on the ES1DV device body?
The ES1DV device body is laser-marked with "ES1DV" as the ordering code, per the manufacturer's marking diagram. No additional alphanumeric suffixes or date codes appear on the top surface - only the part number itself, along with a cathode band indicating polarity. This matches the official TSC documentation for Version C2102.
How does the ES1DV's thermal resistance compare to similar SMA-packaged rectifiers?
The ES1DV specifies RθJA = 85 °C/W and RθJL = 35 °C/W. These values are competitive with industry-standard ultra-fast SMA rectifiers (e.g., MUR120: RθJA ≈ 75–90 °C/W). The ES1DV's RθJL indicates efficient heat transfer to the PCB pad, supporting thermal performance when mounted on ≥1 cm² of 2-oz copper with thermal vias - critical for maintaining TJ < 150°C at full 1 A load.
