Product details
Overview
ES3DBH from Taiwan Semiconductor is a 3A, 200V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3.0A/25°C, and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.
For engineers reviewing the ES3DBH datasheet, ES3DBH pinout, ES3DBH application, or ES3DBH equivalent, key selection criteria include peak repetitive reverse voltage (200V), surge current capability (100A), thermal resistance (RθJL = 24°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance.
Technical Context
The ES3DBH is a single-die, glass-passivated silicon junction rectifier optimized for high-frequency switching applications. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses in hard-switched topologies, while low forward voltage (VF = 0.86 V @ 3A, 25°C) improves conduction efficiency.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and features moisture sensitivity level 1 (J-STD-020), matte tin-plated leads per J-STD-002, and JESD201 Class 2 whisker resistance - all validated for under-hood environments with thermal cycling and vibration exposure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in snubber or freewheeling paths. |
| IF | 3 A continuous - Rated average forward current; supports compact PCB layouts without forced air cooling. |
| trr | ≤35 ns - Ultra-fast recovery enables operation up to ~1 MHz in DC-DC converters without excessive ringing. |
| VF @ 3A, 25°C | 0.86 V - Low conduction loss reduces power dissipation by ~25% vs. standard fast rectifiers at same current. |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance measured on 10 mm × 10 mm Cu pad; enables direct thermal coupling to PCB ground plane. |
| IFSM | 100 A - Non-repetitive surge rating allows robust handling of inductive turn-off transients in motor drives. |
| Junction Temp | –55°C to +150°C - Full automotive temperature range ensures reliability in engine compartment and lighting modules. |

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-M3/45 | Same DO-214AA package, 200V VRRM, but trr = 50 ns (vs. 35 ns); VF = 0.95 V @ 3A. | Higher recovery time increases switching loss in >500 kHz designs; suitable for lower-frequency industrial SMPS. | Select ES3DBH where trr ≤ 35 ns is required for EMI reduction or high-frequency efficiency. |
| ON Semiconductor MUR320HE3/A | DO-214AC (SMA) package (smaller footprint), 200V, trr = 35 ns, but IF = 3A derated to 2.1A at 100°C ambient. | SMA package limits thermal dissipation; not recommended for sustained 3A operation above 70°C ambient. | Choose ES3DBH for full 3A continuous current capability with SMB thermal performance and automotive qualification. |
Compared with VS-3EYH02-M3/45 and MUR320HE3/A, ES3DBH delivers superior high-frequency efficiency via faster recovery and maintains full 3A rating at elevated temperatures due to lower RθJA (84°C/W) and AEC-Q101 validation for automotive deployment.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES3DBH?
The ES3DBH has a maximum repetitive peak reverse voltage (VRRM) of 200 V, as confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2102). This rating defines the highest reverse voltage the device can block continuously without breakdown under specified thermal conditions and is strictly applicable to ES3DBH - not extrapolated from adjacent variants like ES3CBH (150 V) or ES3FBH (300 V).
Is ES3DBH suitable for automotive applications?
Yes, ES3DBH is AEC-Q101 qualified per the manufacturer's documentation, with validation across temperature cycling, humidity, mechanical shock, and board-level reliability tests. Its DO-214AA (SMB) package, matte tin-plated leads, and –55°C to +150°C junction temperature range make ES3DBH appropriate for under-hood and interior automotive systems including LED lighting drivers and DC-DC converters.
What is the forward voltage drop of ES3DBH at 3.0A and 25°C?
The forward voltage (VF) of ES3DBH is 0.86 V at 3.0 A and 25°C junction temperature, as specified in the Electrical Specifications table under "ES3ABH – ES3DBH" grouping. This value is measured with a 0.3 ms pulse width and is distinct from higher-voltage variants (e.g., ES3FBH shows 0.98 V at same conditions).
Does ES3DBH have a defined reverse recovery time?
Yes, ES3DBH has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications section for the ES3ABH–ES3DBH subgroup and confirms its classification as a super fast recovery rectifier suitable for high-frequency switching.
What package type does ES3DBH use, and is it lead-free?
ES3DBH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability standards. It is RoHS-compliant and halogen-free per IEC 61249-2-21, with no lead content - verified in the Mechanical Data and Ordering Information sections of the TSC datasheet.
