Product details
Overview
ES3B V7G from Taiwan Semiconductor is a 3A, 100V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 3A/25°C, and 100A peak surge current - used for high-frequency freewheeling in switching-mode power supplies.
For engineers reviewing the ES3B V7G datasheet, ES3B V7G pinout, ES3B V7G application, or ES3B V7G equivalent, key selection criteria include repetitive peak reverse voltage (100V), thermal resistance (RθJL = 12°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This single-die, glass-passivated super fast rectifier delivers low forward voltage drop and minimal reverse recovery charge, enabling high-efficiency operation in DC-DC converters and offline SMPS where switching frequencies exceed 100 kHz. Its DO-214AB package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
The device operates across –55°C to +150°C junction temperature, with 12°C/W junction-to-lead thermal resistance ensuring stable thermal performance under sustained 3A conduction. Reverse leakage remains ≤10 µA at 25°C and ≤500 µA at 100°C, supporting reliable blocking in high-temperature 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-3EYH01-M3/54 | Same DO-214AB package, 100V VRRM, but VF = 1.05V (max) at 3A; trr = 35ns typical | Slightly higher conduction loss; identical thermal and surge ratings | Preferred where Vishay supply chain alignment is required; verify layout compatibility for cathode band orientation |
| ON Semiconductor MUR3100CT | TO-220AC package (not SMD); dual common-cathode configuration; 100V VRRM, VF = 1.2V (max) | Requires through-hole assembly and larger board area; not drop-in compatible | Consider only when higher surge margin or heatsink mounting is needed; not suitable for space-constrained SMT designs |
Compared with VS-3EYH01-M3/54 and MUR3100CT, the ES3B V7G offers superior SMT manufacturability, lowest VF in its voltage class, and tighter thermal resistance - making it optimal for high-density, high-efficiency power supplies where board space and thermal budget are constrained.

FAQ
What is the maximum junction temperature rating for ES3B V7G?
The ES3B V7G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in thermally demanding environments such as enclosed power supplies and industrial control units. The ES3B V7G maintains specified electrical parameters within this full range, and its 12°C/W junction-to-lead thermal resistance supports effective heat dissipation into the PCB.
Does ES3B V7G meet RoHS and halogen-free requirements?
Yes, the ES3B V7G is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms this in the official datasheet revision N2102. The molding compound is UL 94V-0 rated, and terminals are matte tin plated per J-STD-002. These certifications make the ES3B V7G suitable for consumer, enterprise, and industrial end equipment subject to strict environmental regulations.
What is the reverse recovery time (trr) specification for ES3B V7G?
The ES3B V7G has a reverse recovery time (trr) of 35 ns maximum, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed in the Electrical Specifications table of the official TSC datasheet. The fast trr directly contributes to reduced switching losses and lower EMI in high-frequency power converters using the ES3B V7G as a freewheeling or output rectifier.
Is ES3B V7G pin-compatible with other ES3x family members?
Yes, all ES3x devices including ES3B V7G share identical DO-214AB (SMC) package dimensions, pinout, and terminal configuration - anode and cathode are fixed per standard SMC polarity marking. However, VRRM, VF, and CJ vary across the family; therefore, substitution requires verification of voltage, loss, and capacitance requirements. The ES3B V7G is mechanically interchangeable but electrically distinct from ES3F or ES3J.
What packaging and reel quantity is offered for ES3B V7G?
The ES3B V7G is supplied in DO-214AB (SMC) package on tape-and-reel format, with 3,000 units per reel. This packaging supports automated pick-and-place assembly and complies with J-STD-020 moisture sensitivity level 1, eliminating the need for pre-baking before reflow. The reel specification is documented in the Ordering Information section of the Taiwan Semiconductor ES3A–ES3J datasheet (Rev. N2102).
