Product details
Overview
ES3DH from Taiwan Semiconductor is a 3A, 200V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 3A/25°C, and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.
For engineers reviewing the ES3DH datasheet, ES3DH pinout, ES3DH application, or ES3DH equivalent, key selection criteria include repetitive peak reverse voltage (200V), junction-to-lead thermal resistance (12°C/W), moisture sensitivity level (J-STD-020 Level 1), and compatibility with automated placement in high-efficiency power supplies.
Technical Context
The ES3DH uses a single-die, glass-passivated silicon junction optimized for super-fast switching in unidirectional power conversion. Its 35ns trr and low 0.95V VF at rated current support high-frequency operation in compact DC-DC topologies while maintaining thermal stability up to 150°C junction temperature.
Designed for automotive-grade reliability, the ES3DH meets AEC-Q101 stress testing requirements and features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance - critical for under-hood lighting and snubber applications where long-term bias stability is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 3 A - continuous forward current rating; supports sustained conduction in 12–48V automotive power rails |
| trr | 35 ns - measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables >100 kHz switching without excessive switching loss |
| VF @ 3A, 25°C | 0.95 V - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| RθJL | 12 °C/W - junction-to-lead thermal resistance; allows direct PCB copper pour heat sinking without heatsink |
| IR @ 200V, 25°C | 10 µA - low leakage ensures minimal standby power loss in battery-backed systems |
| CJ @ 1MHz, 4V | 45 pF - junction capacitance affects high-frequency noise coupling and EMI filter design |

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-M3/57T | Same DO-214AB package, 200V VRRM, but VF = 1.05V @ 3A; trr = 30ns; no AEC-Q101 claim | Not certified for automotive; suitable for industrial/commercial SMPS only | Select if AEC-Q101 is not required and slightly faster trr is prioritized over VF |
| ON Semiconductor MUR320RLG | DO-214AB, 200V, VF = 0.93V @ 3A, trr = 35ns, AEC-Q101 qualified; lead finish differs (matte Sn vs Pb-free) | Identical electrical specs and qualification; different marking and traceability documentation | Drop-in alternative where ON Semi's supply chain or PPAP documentation is preferred |
Compared with VS-3EYH02-M3/57T and MUR320RLG, the ES3DH offers the lowest VF among AEC-Q101-qualified 200V 3A super fast rectifiers in DO-214AB, delivering optimal conduction efficiency in thermally constrained automotive modules without sacrificing recovery speed.

FAQ
What is the maximum junction temperature rating for ES3DH?
The ES3DH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 thermal cycling tests. This rating allows reliable operation in under-hood environments where ambient temperatures reach 125°C, provided thermal design maintains junction temperature below this limit using the specified RθJL of 12°C/W. The ES3DH datasheet confirms this value across all versions of the ES3xH series.
Is ES3DH compatible with lead-free reflow soldering processes?
Yes, ES3DH is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its DO-214AB package is rated for peak reflow temperatures up to 260°C per J-STD-020 Level 1. No pre-baking is required due to its moisture sensitivity level, making ES3DH suitable for standard high-volume SMT lines without process modification.
Does ES3DH have a specified reverse recovery charge (Qrr)?
The ES3DH datasheet does not publish a direct Qrr value; however, its reverse recovery time (trr = 35 ns) is measured under standardized conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), enabling estimation of Qrr using industry-standard formulas. For precise Qrr-dependent design (e.g., snubber sizing), engineers should refer to the ES3DH's trr curve in Figure 7 and validate with bench measurement, as Qrr is not guaranteed in the official specifications.
What is the marking code printed on the ES3DH device body?
The ES3DH is marked with "ES3D" on the device body, per the manufacturer's ordering code convention where "x" in ES3xH corresponds to the voltage grade (D = 200V). This marking appears adjacent to the cathode band on the DO-214AB package and is used for visual identification and traceability during assembly and inspection. No date code or factory code is included in the base marking.
How does ES3DH compare to ES3CH in terms of forward voltage and application suitability?
ES3DH (200V) and ES3CH (150V) share identical package, trr (35 ns), and thermal specs, but ES3DH exhibits 0.95V VF at 3A/25°C versus ES3CH's 0.93V - a negligible 20mV difference. The higher VRRM makes ES3DH preferable in 24V+ automotive systems where transient clamping headroom is critical, while ES3CH remains optimal for 12V-only applications with tighter VF budgets.
