Product details

Overview

ES3GHM6G from Taiwan Semiconductor is a 3A, 400V super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 3A/25°C, and 100A peak surge current capability; used in high-frequency switching mode power supplies for computer and telecom systems.

For engineers reviewing the ES3GHM6G datasheet, ES3GHM6G pinout, ES3GHM6G application, or ES3GHM6G equivalent, key selection criteria include V_RRM = 400V, I_F = 3A, t_rr = 35ns, thermal resistance R_θJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT placement.

Technical Context

This single-die, unidirectional silicon rectifier employs glass-passivated junction technology to achieve stable performance across -55°C to +150°C operating temperature range. Its super-fast recovery enables efficient operation in SMPS operating above 100kHz, minimizing switching losses during freewheeling and output rectification phases.

The device exhibits low junction capacitance (30pF at 1MHz/4V), enabling reduced capacitive coupling in high-speed circuits, and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements for robust reflow compatibility.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 400V-rated DC bus or flyback clamp applications.
I_F	3 A - Continuous average forward current rating at T_L = 75°C; determines steady-state power delivery capacity in rectifier legs.
t_rr	35 ns - Measured reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables high-frequency switching (>200kHz) with minimal commutation loss.
V_F (max)	1.30 V - Forward voltage drop at 3A/25°C; directly impacts conduction loss and thermal design in high-current output stages.
R_θJA	47 °C/W - Junction-to-ambient thermal resistance; sets baseline for heatsinking requirements on standard FR-4 PCB with 1-inch² copper pad.
I_FSM	100 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush current handling during cold-start of AC-DC converters.

Pinout & Package

Package: DO-214AB (SMC), surface-mount, molded plastic case with matte tin-plated leads; polarity indicated by cathode band; weight ≈ 0.210g; UL 94V-0 rated compound.

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 = 35ns, but uses DO-214AC (SMA) package (smaller footprint, lower thermal mass)	Lower R_θJA (65°C/W) limits usable current in high-ambient environments; unsuitable where board space allows DO-214AB but thermal headroom is constrained.	Select when PCB area is critical and peak current < 2.2A; verify thermal derating using actual layout.
ON Semiconductor MUR340G	V_RRM = 400V, I_F = 3A, t_rr = 50ns, DO-201AD axial package - not surface-mount compatible	Requires through-hole assembly and manual rework; incompatible with automated SMT lines and high-density layouts.	Use only for prototyping or legacy repair where DO-214AB footprint is unavailable; avoid for volume production.

Compared with VS-3EYH04-M3/45 and MUR340G, ES3GHM6G delivers identical electrical performance in a DO-214AB package optimized for automated placement, higher thermal mass, and J-STD-020 Level 1 compliance-making it preferred for high-volume, RoHS-compliant industrial and telecom power designs.

FAQ

What is the maximum junction temperature rating for ES3GHM6G?

The ES3GHM6G has a maximum junction temperature (T_J) of +150°C and a minimum storage temperature of –55°C. This rating allows reliable operation in industrial ambient conditions up to +85°C when mounted on a standard FR-4 PCB with adequate copper area. The thermal performance is validated per JEDEC JESD51-2, with R_θJA = 47°C/W under defined test conditions.

Does ES3GHM6G meet RoHS and halogen-free requirements?

Yes, ES3GHM6G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminals are matte tin-plated to satisfy both environmental and solderability standards (J-STD-002). Certificate of Compliance is available upon request from Aetrix Electronics.

What is the reverse recovery time test condition for ES3GHM6G?

The reverse recovery time (t_rr) of 35ns for ES3GHM6G is measured under standardized conditions: forward current I_F = 0.5A, reverse current I_R = 1.0A, and reverse recovery current I_rr = 0.25A, per JEDEC JESD24-11. This value reflects real-world behavior in high-frequency switching circuits and is guaranteed across the full operating temperature range.

Can ES3GHM6G be used as a direct replacement for ES3G in existing designs?

Yes, ES3GHM6G is the same electrical and mechanical specification as ES3G - both are 400V, 3A super-fast rectifiers in DO-214AB (SMC) package with identical marking (ES3G), thermal characteristics, and pinout. The "HM6G" suffix denotes tape-and-reel packaging (3,000 pcs/reel) and green compound; no design changes are required when substituting ES3GHM6G for ES3G.

What is the typical junction capacitance of ES3GHM6G and how does it affect circuit performance?

The typical junction capacitance (C_J) of ES3GHM6G is 30pF at 1MHz and 4.0V reverse bias. This low capacitance minimizes displacement current during voltage transitions, reducing EMI in high-frequency converters and improving noise immunity in sensitive analog sections sharing the same ground plane as the ES3GHM6G rectifier stage.
