Product details

Overview

ES3G V7G from Taiwan Semiconductor is a 400V, 3A 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 - deployed in high-frequency switching mode power supplies for telecom infrastructure.

For engineers reviewing the ES3G V7G datasheet, ES3G V7G pinout, ES3G V7G application, or ES3G V7G equivalent, key selection criteria include repetitive peak reverse voltage (400V), 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 super-fast recovery (t_rr ≤ 35 ns) under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions. Its DO-214AB (SMC) package supports automated placement and meets JESD201 Class 2 whisker resistance.

The device operates across –55°C to +150°C junction temperature range with R_θJA = 47°C/W and R_θJL = 12°C/W. Reverse leakage is limited to 10 µA at 25°C and 500 µA at 100°C under rated V_RRM, and junction capacitance is 30 pF at 1 MHz / 4.0 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum non-repetitive reverse voltage the device blocks without breakdown
I_F	3 A continuous - average forward current rating at case temperature ≤ 75°C
t_rr	≤ 35 ns - enables high-frequency operation up to ~3 MHz in SMPS topologies
V_F (max)	1.30 V @ 3 A, 25°C - determines conduction loss and thermal load in high-duty-cycle rectification
R_θJL	12 °C/W - critical for heatsinkless PCB layout where lead-to-board thermal path dominates cooling
I_FSM	100 A @ 8.3 ms - withstands inrush and transient surges in AC-DC front-end stages
C_J	30 pF @ 1 MHz, 4 V - low capacitance minimizes switching noise and EMI in high-dV/dt environments

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-ES3GHE3/5BT	Same DO-214AB package, 400 V V_RRM, but t_rr = 25 ns (typ), V_F = 1.25 V (max)	Lower t_rr enables marginally higher frequency use; tighter V_F tolerance aids parallel operation	Preferred where <25 ns t_rr is required or when paralleling multiple units for >3 A average current
ON Semiconductor ES3G	Identical V_RRM, I_F, and t_rr specs; differs in marking (no "V7G"), RoHS/halogen status per batch	No functional difference in circuit operation; may require qualification for legacy BOM migration	Suitable for drop-in replacement if existing design qualified with ON's ES3G and no date-code or green compound traceability is mandated

Compared with VS-ES3GHE3/5BT and ON Semiconductor ES3G, the ES3G V7G offers identical core electrical performance but adds explicit MSL Level 1 compliance and halogen-free certification per IEC 61249-2-21 - critical for high-reliability telecom and industrial production programs requiring full material declarations.

FAQ

What is the maximum junction temperature rating for ES3G V7G?

The ES3G V7G has a maximum junction temperature (T_JMAX) of +150°C and a minimum of –55°C. This rating allows reliable operation in high-ambient environments such as enclosed telecom power shelves or industrial motor drive cabinets. The ES3G V7G maintains specified electrical parameters within this full range, provided thermal design respects R_θJL = 12°C/W and R_θJA = 47°C/W limits.

Does ES3G V7G support lead-free reflow soldering?

Yes, ES3G V7G supports lead-free reflow soldering per J-STD-002. Its matte tin-plated leads are compatible with Pb-free SAC305 profiles, and its MSL Level 1 classification means it can be stored indefinitely before assembly without baking. The ES3G V7G also complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21.

What is the reverse recovery time specification for ES3G V7G?

The ES3G V7G has a maximum reverse recovery time (t_rr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor N2102 datasheet. The ES3G V7G's 35 ns t_rr enables efficient operation in switching power supplies operating up to approximately 3 MHz, reducing switching losses relative to standard fast rectifiers.

Is ES3G V7G pin-compatible with other ES3x series devices?

Yes, all ES3x devices including ES3G V7G share the same DO-214AB (SMC) package, anode/cathode pinout, and mechanical footprint. However, V_RRM, V_F, and C_J vary across the series (e.g., ES3A = 50 V, ES3J = 600 V). The ES3G V7G is electrically optimized for 400 V applications and must not be substituted with lower-voltage variants without derating analysis.

What packaging format is offered for ES3G V7G?

The ES3G V7G is supplied in tape-and-reel format, 3,000 units per reel, compatible with standard SMT pick-and-place equipment. The DO-214AB (SMC) carrier tape meets EIA-481 standards, and the reel labeling includes full part number, date code (YW), factory code (F), and green compound indicator (G) per Taiwan Semiconductor's marking diagram.
