Product details

Overview

ES3HBHM4G from Taiwan Semiconductor is a 3A, 600V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 1.11V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 34pF junction capacitance - deployed in high-frequency SMPS output stages for efficiency-critical AC/DC adapters.

For engineers reviewing the ES3HBHM4G datasheet, ES3HBHM4G pinout, ES3HBHM4G application, or ES3HBHM4G equivalent, key selection criteria include V_RRM=600V, I_F=3A, 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 uses a glass-passivated single-die PN junction optimized for high-speed switching. Its 35ns reverse recovery time enables operation in 100–500kHz SMPS topologies without excessive switching loss or EMI generation.

The device operates across -55°C to +150°C junction temperature range with 100A surge rating (8.3ms half-sine), and achieves low forward conduction loss via optimized doping profile - evidenced by VF=1.24V max at 3A/25°C and VF=0.99V at 3A/125°C.

Key Specifications

V_RRM	600 V - supports input rectification in universal-input (85–265VAC) offline SMPS with ≥2× safety margin
I_F	3 A continuous - delivers sufficient output current for 30–40W adapter designs without forced cooling
t_rr	35 ns - enables high-frequency operation up to 500 kHz while limiting switching loss and diode-induced ringing
V_F @ 3A, 25°C	1.24 V max - reduces conduction loss to <0.37 W per diode at full load, improving system efficiency
C_J @ 1MHz, 4V	34 pF - minimizes capacitive coupling noise and improves EMI filter design margin in compact layouts
R_θJA	84 °C/W - allows 3A operation on standard 10mm × 10mm Cu pad PCB without heatsink in ambient ≤50°C

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES3HB-M3/5BT	Identical V_RRM=600V, I_F=3A, t_rr=35ns; same SMB package but different marking and tape/reel orientation	No functional difference in SMPS or adapter use; compatible with same footprint and thermal pad layout	Select for dual-sourcing where Vishay supply chain preference applies
ON Semiconductor MUR360RLG	Higher V_RRM=600V, same I_F=3A, but t_rr=60ns (vs. 35ns) and V_F=1.45V max at 3A - higher conduction and switching loss	Suitable for lower-frequency (<150kHz) converters; less optimal for high-efficiency USB PD or thin adapters	Choose only if ES3HBHM4G lead time exceeds 12 weeks and frequency requirements permit higher t_rr

FAQ

What is the maximum junction temperature rating for ES3HBHM4G?

The ES3HBHM4G has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version C2102. This rating allows reliable operation in enclosed industrial power supplies and high-ambient LED drivers. Derating curves confirm 3A continuous current is sustainable up to 75°C ambient when mounted on a 10mm × 10mm copper pad - essential for thermal design validation of the ES3HBHM4G.

Does ES3HBHM4G meet RoHS and halogen-free requirements?

Yes, ES3HBHM4G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated per J-STD-002. These certifications are confirmed for the ES3HBHM4G variant and apply to all units shipped under this part number.

What is the reverse recovery time (t_rr) specification for ES3HBHM4G?

The reverse recovery time for ES3HBHM4G is specified as ≤35ns under test conditions of I_F=0.5A, I_R=1.0A, and I_RR=0.25A, per the Electrical Specifications table on page 2 of the Taiwan Semiconductor datasheet. This value is measured at 25°C and remains stable across the full operating temperature range, making ES3HBHM4G suitable for high-frequency SMPS designs above 200kHz.

Is ES3HBHM4G pin-compatible with other devices in the ES3x series?

Yes, all ES3AB–ES3JB variants, including ES3HBHM4G, share identical DO-214AA (SMB) package dimensions, pinout, and thermal pad layout. The anode and cathode terminals are fixed across the family, enabling direct substitution within the same voltage grade - provided V_RRM, V_F, and t_rr meet circuit requirements. No PCB redesign is needed when upgrading from ES3GB to ES3HBHM4G.

What is the forward voltage (V_F) of ES3HBHM4G at 3A and 125°C?

At 3A forward current and 125°C junction temperature, the ES3HBHM4G exhibits a maximum forward voltage of 1.13V, as specified in the Electrical Specifications table (page 2). This elevated V_F reflects silicon behavior under thermal stress and is critical for worst-case power loss calculation - resulting in ≤3.4W dissipation per device at full load and high ambient, informing heatsink and airflow decisions for the ES3HBHM4G.
