Product details

Overview

ES3F V7G from Taiwan Semiconductor is a 3A, 400V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 3A/25°C, and 100A peak surge current - used in high-frequency switching mode power supplies for telecom and computing.

For engineers reviewing the ES3F V7G datasheet, ES3F V7G pinout, ES3F V7G application, or ES3F V7G equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (R_θJA = 47°C/W), junction capacitance (30pF), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve super-fast recovery (trr ≤ 35ns) with low forward voltage drop and minimal stored charge - enabling high-efficiency operation in 100–500 kHz SMPS topologies. Its DO-214AB package supports automated placement and provides robust thermal dissipation via lead-frame conduction.

The device operates across –55°C to +150°C junction temperature range, with 12°C/W junction-to-lead thermal resistance and 47°C/W junction-to-ambient rating. Reverse leakage remains ≤10 µA at 25°C and ≤500 µA at 100°C under rated VR, ensuring stable blocking performance in thermally demanding environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in bridge or freewheeling configurations
I_F	3 A continuous - average forward current rating at 75°C case temperature; determines steady-state power handling capability
I_FSM	100 A - non-repetitive surge current tolerance for 8.3 ms half-sine; enables robustness against inrush and fault transients
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; critical for minimizing switching losses in high-frequency converters
V_F	≤1.30 V at I_F = 3 A, T_J = 25°C - forward voltage drop directly impacts conduction loss and thermal design margin
C_J	30 pF at 1 MHz, V_R = 4.0 V - junction capacitance affects high-frequency noise coupling and snubber sizing
R_θJA	47 °C/W - thermal resistance from junction to ambient under standard PCB mounting; used to calculate max allowable power dissipation

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-ES3FHM3	Same DO-214AB package, identical 400V V_RRM, but t_rr = 30 ns (5 ns faster); V_F = 1.25 V max	Slightly lower conduction and switching loss; preferred where <5 ns t_rr reduction justifies sourcing from alternate vendor	Select VS-ES3FHM3 when optimizing for lowest possible recovery-related EMI in ultra-high-frequency designs
ON Semiconductor MUR340G	Same 3A/400V rating, DO-214AC (SMA) package (smaller footprint), t_rr = 50 ns, V_F = 1.35 V max	Lower thermal performance (R_θJA ≈ 65°C/W) and slower recovery; suitable only for lower-power or lower-frequency use cases	Choose MUR340G only if board space is constrained and thermal budget permits higher junction rise

Compared with VS-ES3FHM3 and MUR340G, ES3F V7G delivers balanced performance: tighter thermal resistance than MUR340G and more cost-effective sourcing than VS-ES3FHM3, while meeting strict 35ns t_rr and 47°C/W R_θJA requirements for mainstream telecom and server PSUs.

FAQ

What is the maximum junction temperature rating for ES3F V7G?

The ES3F V7G has a maximum junction temperature (T_J) of +150°C and a minimum storage temperature of –55°C. This wide operating range allows reliable deployment in thermally aggressive environments such as enclosed telecom power modules or industrial motor drives. The device's 12°C/W junction-to-lead thermal resistance supports efficient heat transfer to the PCB, making ES3F V7G suitable for sustained 3A operation with proper copper layout.

Does ES3F V7G have a specified moisture sensitivity level (MSL)?

Yes, ES3F V7G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates yield risk from moisture-induced popcorning. The DO-214AB (SMC) package construction and glass passivation contribute to this robust MSL rating, confirming ES3F V7G's suitability for high-volume automated assembly lines.

What is the reverse recovery time (t_rr) specification for ES3F V7G?

The ES3F V7G has a maximum reverse recovery time (t_rr) of 35 ns, tested under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet and applies directly to ES3F V7G - not extrapolated from adjacent variants. The 35 ns t_rr enables efficient operation in 200–500 kHz switching converters, reducing switching loss and associated EMI compared to standard fast recovery diodes.

Is ES3F V7G RoHS and halogen-free compliant?

Yes, ES3F V7G meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating (matte tin on leads) complies with JEDEC J-STD-002 solderability standards. These certifications are documented in Taiwan Semiconductor's product compliance reports and apply to the full ES3x family, including ES3F V7G.

What does the 'V7G' suffix indicate in ES3F V7G?

The 'V7G' suffix in ES3F V7G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'V' indicates tape-and-reel packaging (3,000 pcs/reel), '7' specifies green molding compound (halogen-free), and 'G' confirms RoHS compliance. This suffix is consistent across the ES3x series and does not affect electrical parameters - ES3F V7G shares identical V_RRM, t_rr, V_F, and thermal specs with other ES3F-marked variants in DO-214AB (SMC) package.
