Product details

Overview

ES2G from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 2 A average forward current, super fast recovery (35 ns) surface-mount rectifier in DO-214AA (SMB) package, featuring 1.30 V max forward voltage at 2 A and 20 pF junction capacitance - used in snubber networks and DC-DC converter freewheeling paths.

For engineers reviewing the ES2G datasheet, ES2G pinout, ES2G application, or ES2G equivalent, key selection criteria include its 400 V V_RRM, 35 ns trr, 1.30 V V_F @ 2 A, DO-214AA thermal performance (R_θJL = 20 °C/W), and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

The ES2G is a single-die, silicon planar super fast rectifier with glass-passivated junction, optimized for high-frequency switching applications where low forward voltage and rapid reverse recovery minimize conduction and switching losses. Its 35 ns reverse recovery time enables efficient operation in 100–500 kHz SMPS topologies.

Thermally, the DO-214AA (SMB) package delivers R_θJL = 20 °C/W and R_θJA = 75 °C/W, supporting 2 A continuous forward current up to 150 °C junction temperature. Polarity is marked by cathode band; leads are matte tin-plated per J-STD-002.

Key Specifications

V_RRM	400 V - maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback/clamp circuits
I_F	2 A - continuous average forward current at T_A = 75 °C; sets baseline conduction capability
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables high-frequency switching with low recovery loss
V_F	1.30 V max @ 2 A, 25 °C - directly impacts conduction loss and thermal rise in high-duty-cycle operation
C_J	20 pF @ 1 MHz, 4 V - low junction capacitance reduces capacitive switching loss and EMI in hard-switched converters
I_FSM	50 A @ 8.3 ms half-sine - supports surge immunity during startup or fault conditions without bond-wire failure

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR240	Same DO-214AA package, 400 V V_RRM, but 50 ns t_rr and 1.35 V V_F @ 2 A	Higher recovery time increases switching loss in >200 kHz designs	Prefer ES2G where t_rr ≤ 35 ns is critical for efficiency

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for ES2G?

The ES2G has a maximum repetitive peak reverse voltage (V_RRM) of 400 V, verified per Taiwan Semiconductor's L2102 datasheet. This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is critical for selecting appropriate voltage margin in clamp and output rectifier circuits. The ES2G is part of the ES2A–ES2J series, where 'G' explicitly denotes the 400 V grade.

What is the forward voltage (V_F) specification for ES2G at rated current?

The ES2G exhibits a maximum forward voltage (V_F) of 1.30 V at 2 A forward current and 25 °C junction temperature, as specified in the electrical characteristics table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly determines conduction loss and thermal dissipation in continuous operation. It is higher than ES2A–ES2D (0.95 V) due to higher voltage-grade process optimization.

Does ES2G have a defined reverse recovery time (t_rr) and how is it measured?

Yes, the ES2G 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 parameter reflects the time required for the device to transition from conduction to blocking state and is essential for minimizing switching loss in high-frequency converters. The 35 ns value places ES2G in the super fast recovery category, distinct from standard or fast recovery rectifiers.

What package type and mounting style does ES2G use?

The ES2G uses the DO-214AA (SMB) surface-mount package, confirmed by mechanical data and ordering information. It features matte tin-plated leads compliant with J-STD-002 solderability, a cathode band for polarity identification, and a UL 94V-0 rated molding compound. The SMB footprint supports automated placement and offers superior thermal resistance (R_θJL = 20 °C/W) compared to smaller packages like SMA.

Is ES2G RoHS and halogen-free compliant?

Yes, the ES2G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This compliance ensures suitability for environmentally regulated end equipment including consumer electronics, industrial controls, and LED lighting systems where restricted substance restrictions apply.
