Product details
Overview
ES3GBH from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 3 A average forward current super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35 ns reverse recovery time and 41 pF junction capacitance at 1 MHz / 4 V, used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the ES3GBH datasheet, ES3GBH pinout, ES3GBH application, or ES3GBH equivalent, key selection criteria include its AEC-Q101 qualification, glass passivated junction, low-profile SMB package, TJ = –55°C to +150°C operating range, and 100 A surge rating for transient robustness.
Technical Context
The ES3GBH is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications requiring fast recovery and low forward voltage. Its 35 ns trr and 0.98 V typical VF at 3 A / 25°C enable reduced switching losses in compact power supplies.
Thermally, it delivers RθJL = 24°C/W and RθJA = 84°C/W on a 10 mm × 10 mm Cu pad PCB, supporting continuous 3 A operation with appropriate board-level heat sinking. Polarity is marked by a cathode band on the DO-214AA case.
Key Specifications

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-3EYH04-M3/45 | Same DO-214AA package; VRRM = 400 V, trr = 35 ns, but VF = 1.15 V (max) at 3 A - higher conduction loss | Not AEC-Q101 qualified; limited to industrial/commercial automotive peripherals | Select when cost sensitivity outweighs automotive qualification requirements |
| ON Semiconductor MUR340G | DO-204AL (DO-41) through-hole package; VRRM = 400 V, trr = 50 ns - slower recovery and incompatible mounting | Requires PCB redesign; unsuitable for automated SMT lines or space-constrained modules | Select only for legacy through-hole designs where rework is acceptable |
Compared with VS-3EYH04-M3/45 and MUR340G, the ES3GBH offers AEC-Q101 compliance, lower forward voltage, and SMT-ready DO-214AA packaging-making it the preferred choice for new automotive power designs requiring reliability, efficiency, and manufacturability.

FAQ
What is the peak repetitive reverse voltage rating of the ES3GBH?
The ES3GBH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is explicitly specified in the Absolute Maximum Ratings table for the ES3GBH variant in the official Taiwan Semiconductor datasheet (Version A2102). It defines the maximum reverse-biased voltage the device can block continuously without breakdown under normal operating conditions.
Is the ES3GBH qualified for automotive applications?
Yes, the ES3GBH is AEC-Q101 qualified. This qualification is confirmed in the FEATURES section of the Taiwan Semiconductor datasheet and applies specifically to the ES3ABH–ES3JBH family, including ES3GBH. It validates performance across temperature cycling, high-temperature reverse bias, and mechanical shock tests required for automotive under-hood and cabin use.
What is the forward voltage drop of the ES3GBH at 3 A and 25°C?
The typical forward voltage drop (VF) of the ES3GBH is 0.98 V at 3 A and 25°C, with a maximum of 1.13 V under the same conditions. These values are listed in the ELECTRICAL SPECIFICATIONS table for the ES3FBH/ES3GBH group in the official datasheet, measured using pulse testing (PW = 0.3 ms).
What package type does the ES3GBH use, and what are its key mechanical features?
The ES3GBH uses the DO-214AA (SMB) surface-mount package. Key mechanical features include a low profile (≤2.6 mm height), matte tin-plated solderable leads compliant with J-STD-002, UL 94V-0 molding compound, cathode polarity indicated by a band, and a weight of approximately 0.110 g - all verified in the MECHANICAL DATA section of the Taiwan Semiconductor datasheet.
What is the reverse recovery time (trr) of the ES3GBH, and how is it measured?
The reverse recovery time (trr) of the ES3GBH is 35 ns maximum, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the ELECTRICAL SPECIFICATIONS table. This parameter reflects the time required for the device to transition from forward conduction to reverse blocking, directly impacting switching loss in high-frequency power converters.
