Product details
Overview
ES1DVH from Taiwan Semiconductor is a 1A, 200V 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 AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES1DVH datasheet, ES1DVH pinout, ES1DVH application, or ES1DVH equivalent, key selection criteria include ultra-fast switching performance (trr ≤ 15 ns), junction temperature range (–55°C to +150°C), moisture sensitivity level 1 compliance, and DO-214AC mechanical compatibility with automated SMT placement.
Technical Context
The ES1DVH is a single-die, silicon planar epitaxial ultra-fast rectifier optimized for high-frequency switching applications. Its glass-passivated junction ensures stable operation under thermal cycling, while the matte tin-plated leads meet J-STD-002 solderability requirements.
Designed for DC-DC converters and automotive lighting, the ES1DVH delivers low conduction loss (VF = 0.92 V @ 1 A, 25°C) and minimal stored charge (CJ = 17 pF @ 4 V), enabling efficient energy transfer and reduced EMI in compact power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02UF | Same 1 A / 200 V rating; trr = 12 ns (slightly faster); VF = 0.95 V; TO-277A package (3-lead, no lead bend) | Preferred where board space allows flat-lead SMD packages and tighter trr tolerance is critical | Select STTH1R02UF if layout supports TO-277A and sub-12 ns trr is required for >1 MHz operation |
| ON Semi MUR120E | Same DO-214AC package; trr = 35 ns (slower); VF = 0.93 V; not AEC-Q101 qualified | Suitable for industrial non-automotive DC-DC where qualification is not mandated | Choose MUR120E only for cost-sensitive non-automotive designs where 35 ns trr meets system timing budget |
Compared with STTH1R02UF and MUR120E, the ES1DVH uniquely combines AEC-Q101 qualification, 15 ns trr, and DO-214AC packaging-making it the only option among the three validated for automotive under-hood freewheeling and snubber use without package or reliability trade-offs.
