Product details

Overview

ES3GBHR5G from Taiwan Semiconductor is a 400V, 3A super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.98V forward voltage at 3A/25°C, and 100A surge current capability-designed for high-frequency switching power supplies in compact AC/DC adapters.

For engineers reviewing the ES3GBHR5G datasheet, ES3GBHR5G pinout, ES3GBHR5G application, or ES3GBHR5G equivalent, key selection criteria include V_RRM = 400V, I_F = 3A continuous, t_rr ≤ 35ns, thermal resistance R_θJA = 84°C/W, and SMB package compatibility with automated SMT assembly lines.

Technical Context

This discrete silicon rectifier employs a glass-passivated PN junction to achieve super-fast recovery (t_rr ≤ 35ns) and low forward voltage drop (V_F = 0.98V @ 3A, 25°C), enabling high-efficiency operation in 50–500kHz SMPS topologies. Its single-die configuration and cathode-band polarity marking support unidirectional DC output generation.

Thermal performance is characterized by R_θJL = 24°C/W and R_θJC = 26°C/W on a 10mm × 10mm Cu pad PCB, allowing reliable operation up to T_J = 150°C. Moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to reflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 380V_AC input rectification stages.
I_F	3 A - Continuous forward current rating; supports sustained 36W output in 12V/3A SMPS designs with margin.
t_rr	35 ns - Reverse recovery time; minimizes switching losses and EMI in high-frequency converters (>200kHz).
V_F @ 3A, 25°C	0.98 V - Forward voltage drop; contributes to <1.5W conduction loss at full load, reducing heatsink requirements.
I_FSM	100 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush currents during cold-start of offline PSUs.
R_θJA	84 °C/W - Junction-to-ambient thermal resistance on standard FR-4 PCB; enables natural-convection cooling in space-constrained adapters.

Pinout & Package

Package: DO-214AA (SMB), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity indicated by cathode band.

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	V_RRM = 400V, I_F = 3A, t_rr = 30ns, VF = 0.92V @ 3A - slightly faster but higher cost.	Better suited for >300kHz resonant converters where Q_rr reduction is critical.	Select when optimizing for minimum switching loss over cost-sensitive volume production.
ON Semiconductor MUR340RLG	V_RRM = 400V, I_F = 3A, t_rr = 50ns, VF = 1.05V @ 3A - slower recovery, higher V_F.	Acceptable for 60–150kHz flyback designs where EMI filtering budget permits longer t_rr.	Choose for legacy designs requiring second-source availability with relaxed efficiency targets.

Compared with VS-3EYH04-M3/45 and MUR340RLG, ES3GBHR5G delivers balanced performance: lower cost than Vishay's part while offering superior t_rr and V_F versus ON Semi's MUR340RLG-making it optimal for mid-frequency (150–250kHz), cost-performance-sensitive AC/DC systems.

FAQ

What is the maximum junction temperature rating for ES3GBHR5G?

The ES3GBHR5G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows reliable operation in enclosed, convection-cooled environments up to 75°C ambient when mounted on a 10mm × 10mm copper pad. Derating curves confirm 3A continuous current is sustainable at T_J = 150°C.

Does ES3GBHR5G meet RoHS and halogen-free compliance standards?

Yes, ES3GBHR5G is RoHS-compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. Certificate of Compliance is available upon request from Aetrix Electronics for full BOM validation.

What is the reverse recovery time (t_rr) specification for ES3GBHR5G, and under what test conditions?

The reverse recovery time for ES3GBHR5G is specified as ≤35ns, measured under conditions of I_F = 0.5A, I_R = 1.0A, and I_RR = 0.25A per the Taiwan Semiconductor datasheet. This value is typical across the ES3FB–ES3GB subgroup and confirmed in Characteristic Curve Fig.5, supporting high-frequency switching up to 500kHz with minimal turn-off loss.

Is ES3GBHR5G suitable for use in automotive applications?

No, ES3GBHR5G is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the datasheet notice that "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." It lacks AEC-Q101 qualification, extended temperature screening, and automotive-grade traceability-making it appropriate only for industrial, commercial, and consumer power supplies.

What is the moisture sensitivity level (MSL) and reflow profile guidance for ES3GBHR5G?

ES3GBHR5G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not moisture-sensitive and requires no baking prior to reflow soldering. Standard Pb-free reflow profiles (peak 260°C, 30 seconds max) apply. The device uses matte tin-plated leads compliant with J-STD-002, ensuring robust wetting and intermetallic formation during standard SMT assembly.
