Product details

Overview

ES3B V6G 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 - deployed in high-frequency switching mode power supplies for telecom and computing equipment.

For engineers reviewing the ES3B V6G datasheet, ES3B V6G pinout, ES3B V6G application, or ES3B V6G equivalent, key selection criteria include repetitive peak reverse voltage (100V), thermal resistance (R_θJL = 12°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial-grade power conversion designs.

Technical Context

This discrete silicon rectifier uses a single-die glass-passivated PN junction optimized for high-efficiency freewheeling and output rectification in DC-DC converters and offline SMPS. Its super-fast trr ≤35ns minimizes switching losses during high-frequency operation up to several hundred kHz.

Designed for automated SMT assembly, ES3B V6G meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance. The matte tin-plated leads ensure reliable solderability, and the UL 94V-0 molding compound supports safety-critical board-level integration.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum non-repetitive reverse blocking voltage; defines safe operating margin in 48V-output SMPS secondary-side rectification
I_F	3 A continuous - rated average forward current at T_L = 75°C; supports sustained conduction in compact heatsinkless layouts
I_FSM	100 A - peak surge current for 8.3ms half-sine; withstands inrush and transient overloads without failure
t_rr	35 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables >300kHz switching with low recovery loss
V_F	0.95 V @ 3A, 25°C - forward drop directly impacts conduction loss and thermal rise in high-current paths
R_θJL	12 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without external heatsink
C_J	45 pF @ 1MHz, 4V - low junction capacitance reduces capacitive coupling 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-3EWH01-M3/54	V_RRM = 100V, t_rr = 25ns, V_F = 0.92V @ 3A - faster recovery but same package and current rating	Better suited for >500kHz designs where Q_rr reduction is critical; slightly tighter V_F tolerance	Select when minimizing recovery loss dominates over cost; verify layout compatibility with identical DO-214AB footprint
ON Semiconductor MUR3100E	V_RRM = 1000V, t_rr = 50ns, V_F = 1.25V @ 3A - higher voltage rating, slower recovery, higher V_F	Used in higher-voltage PFC stages or universal-input front-ends; not optimal for low-V_RRM, high-frequency secondary side	Choose only if system requires >600V blocking; otherwise ES3B V6G delivers superior efficiency and thermal performance at 100V

Compared with VS-3EWH01-M3/54 and MUR3100E, ES3B V6G offers the best balance of ultra-fast recovery (35ns), low forward drop (0.95V), and proven manufacturability in DO-214AB - making it ideal for cost-sensitive, high-volume telecom and server power supplies where 100V blocking suffices.

FAQ

What is the maximum junction temperature rating for ES3B V6G?

The ES3B V6G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows deployment in unventilated industrial enclosures and high-ambient telecom equipment. Thermal design must respect R_θJL = 12°C/W to avoid exceeding this limit under 3A continuous load. Derating curves in the ES3B V6G datasheet confirm usable current down to 75°C lead temperature.

Is ES3B V6G RoHS and halogen-free compliant?

Yes, ES3B V6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads meet J-STD-002 solderability requirements. This compliance is verified in Taiwan Semiconductor's material declarations and applies to all ES3B V6G production lots.

What does the 'V6G' suffix indicate in ES3B V6G?

The 'V6G' suffix in ES3B V6G denotes Taiwan Semiconductor's internal packaging and environmental code: 'V' = DO-214AB (SMC) package, '6' = green compound (halogen-free), and 'G' = lead-free, RoHS-compliant finish. It is not a voltage variant - the 'B' in ES3B already specifies 100V V_RRM; V6G confirms full environmental compliance and mechanical form factor.

Can ES3B V6G replace ES3B without suffix in existing designs?

Yes, ES3B V6G is a direct replacement for legacy ES3B variants in terms of electrical specs, package dimensions, and thermal performance. The V6G version adds halogen-free and enhanced RoHS compliance but retains identical V_RRM, I_F, t_rr, and R_θJL. No layout or thermal redesign is needed - only qualification of the new material set per J-STD-020 Level 1 handling.

What is the reverse recovery time test condition for ES3B V6G?

The reverse recovery time (t_rr) of 35ns for ES3B V6G is measured under standardized conditions: I_F = 0.5A forward bias, I_R = 1.0A reverse step, I_rr = 0.25A reverse recovery current threshold, with specified di/dt and voltage slew rate. This matches JEDEC JESD24-11 methodology and is validated across production lots per ES3B V6G datasheet revision N2102.
