Product details

Overview

ES3A V6G from Taiwan Semiconductor is a 3A, 50V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 3A, and 100A peak surge current. It serves as a primary output rectifier in high-frequency AC/DC adapters for telecom power supplies.

For engineers reviewing the ES3A V6G datasheet, ES3A V6G pinout, ES3A V6G application, or ES3A V6G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (R_θJL = 12°C/W), junction temperature range (–55°C to +150°C), and moisture sensitivity level (MSL 1).

Technical Context

This single-die, unidirectional silicon rectifier uses glass-passivated junction technology to achieve stable switching performance under high dv/dt conditions. Its 35ns trr enables efficient operation in 100–500 kHz SMPS topologies without significant switching loss penalties.

The device operates with a maximum junction temperature of 150°C and exhibits low leakage-10 µA at 25°C and 500 µA at 100°C-ensuring reliability in thermally constrained PCB layouts. Thermal resistance values (R_θJL = 12°C/W, R_θJA = 47°C/W) confirm suitability for leaded thermal conduction in compact SMC footprints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits
I_F	3 A continuous - Rated average forward current at T_L = 75°C; determines heatsink-free power handling in 5–12V output rails
t_rr	35 ns - Measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables >300 kHz switching without excessive diode recovery loss
V_F	0.95 V max at I_F = 3A, T_J = 25°C - Directly impacts conduction loss and thermal rise in high-duty-cycle converters
R_θJL	12 °C/W - Junction-to-lead thermal resistance; supports direct copper pour thermal transfer to PCB ground plane
I_FSM	100 A - Peak surge rating for 8.3ms half-sine; withstands inrush and transient overloads in offline input stages
C_J	45 pF at 1 MHz, V_R = 4V - Low junction capacitance minimizes capacitive coupling noise in high-speed gate-drive isolation paths

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-3EYH01-M3/54	Same DO-214AB package, 50V V_RRM, but 50ns t_rr and 1.1V V_F at 3A	Higher conduction and switching loss; less suitable for >200 kHz designs	Acceptable where cost is prioritized over efficiency in low-frequency (<100 kHz) linear-regulated supplies
ON Semiconductor MUR350G	50V V_RRM, 3A I_F, but TO-220AC package (not SMT); 35ns t_rr, 0.92V V_F	Requires through-hole assembly and larger board area; higher R_θJA (50°C/W)	Only viable if legacy through-hole manufacturing is mandated and thermal margin allows

Compared with VS-3EYH01-M3/54 and MUR350G, ES3A V6G delivers superior high-frequency efficiency due to its 35ns t_rr and optimized SMC thermal path, while maintaining full compatibility with automated SMT lines and MSL-1 handling requirements.

FAQ

What is the maximum junction temperature rating for ES3A V6G?

The ES3A V6G has a maximum junction temperature (T_J) rating of +150°C, with a minimum storage temperature of –55°C. This wide operating range allows use in thermally demanding environments such as enclosed telecom power supplies or industrial control cabinets where ambient temperatures exceed 70°C. The ES3A V6G maintains specified electrical parameters within this full range when derated per the forward current derating curve.

Is ES3A V6G suitable for surface-mount reflow soldering?

Yes, ES3A V6G is qualified for standard lead-free reflow soldering per J-STD-020, with Moisture Sensitivity Level (MSL) 1-meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AB (SMC) package is compatible with IPC-7351B land patterns for reliable automated placement and solder joint formation.

What does the "V6G" suffix indicate in ES3A V6G?

The "V6G" suffix in ES3A V6G denotes Taiwan Semiconductor's internal revision and environmental compliance coding: "V" indicates halogen-free compound per IEC 61249-2-21, "6" specifies green molding compound (RoHS-compliant), and "G" confirms lead-free termination and J-STD-002 qualification. It does not affect electrical specifications-the core device remains identical to ES3A per N2102 datasheet version.

How does ES3A V6G compare to ES3B V6G in terms of reverse voltage rating?

ES3A V6G has a repetitive peak reverse voltage (V_RRM) of 50V, whereas ES3B V6G is rated for 100V. Both share identical forward current (3A), surge rating (100A), recovery time (35ns), and package (DO-214AB). The V6G suffix applies identically across the ES3x family, so the only functional difference between ES3A V6G and ES3B V6G is the V_RRM rating-making ES3A V6G appropriate for lower-voltage secondary-side rectification where tighter voltage margins exist.

Can ES3A V6G replace a standard FR304 in a 50V-rated circuit?

ES3A V6G can replace FR304 in 50V-rated circuits only if the application demands super fast recovery-ES3A V6G offers 35ns t_rr versus FR304's typical 500ns. However, FR304 is rated for 400V V_RRM, so direct substitution is unsafe in circuits where reverse voltage exceeds 50V. In verified 50V-clamped or low-V_R freewheeling roles, ES3A V6G provides lower V_F (0.95V vs ~1.3V) and faster switching, improving efficiency and reducing EMI.
