Product details

Overview

ES2G-T from Taiwan Semiconductor is a 2 A, 400 V super fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 2 A and 25°C, and 50 A surge current capability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.

For engineers reviewing the ES2G-T datasheet, ES2G-T pinout, ES2G-T application, or ES2G-T equivalent, key selection criteria include its 400 V V_RRM, 35 ns trr, thermal resistance (R_θJL = 20 °C/W), RoHS/halogen-free compliance, and SMB footprint compatibility with automated SMT assembly.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve stable super-fast switching performance across -55°C to +150°C operating range. Its 35 ns reverse recovery time and low 20 pF junction capacitance enable efficient operation in DC-DC converters and SMPS circuits up to several hundred kHz.

The device is rated for 2 A average forward current with derating above 75°C ambient, supported by a 20 °C/W junction-to-lead thermal resistance and UL 94V-0 molded compound. Cathode polarity is marked by a visible band on the DO-214AA body.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 400 V-rated power rails
I_F	2 A - Continuous average forward current rating at 75°C lead temperature; sets baseline conduction capacity
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 switching loss
V_F (max)	1.30 V - At I_F = 2 A, T_J = 25°C; determines conduction loss and thermal load under full load
R_θJL	20 °C/W - Junction-to-lead thermal resistance; allows direct heatsinking via PCB copper or lead frame for thermal management
I_FSM	50 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance
C_J	20 pF - At 1 MHz, V_R = 4.0 V; limits capacitive coupling and EMI in high-dv/dt environments

Pinout & Package

DO-214AA (SMB) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R04	400 V V_RRM, 2 A I_F, 30 ns t_rr, TO-220AC package	Through-hole mounting; higher thermal mass but no SMT compatibility	Preferred where board-level thermal dissipation requires lead-frame heatsinking or legacy through-hole assembly
SS24H	40 V V_RRM, 2 A I_F, Schottky architecture, 0.55 V V_F	Lower voltage rating; unsuitable for 400 V blocking; zero reverse recovery	Only viable in low-voltage (<60 V) DC-DC outputs where ultra-low V_F outweighs voltage limitation

Compared with STTH2R04 and SS24H, the ES2G-T uniquely combines 400 V blocking, 35 ns recovery, SMB footprint, and 1.30 V forward drop-making it optimal for space-constrained, high-frequency SMT power supplies requiring balanced efficiency and voltage margin.

FAQ

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

The ES2G-T has a V_RRM rating of 400 V, verified per Taiwan Semiconductor's D2305 datasheet revision. This value defines the highest reverse voltage the device can block repeatedly without breakdown. Exceeding 400 V risks avalanche failure, especially at elevated junction temperatures. The ES2G-T is not interchangeable with ES2J-T (600 V) or ES2D-T (200 V) without circuit revalidation.

What is the forward voltage (V_F) of ES2G-T at full rated current?

At I_F = 2 A and T_J = 25°C, the ES2G-T exhibits a maximum forward voltage of 1.30 V, as specified in the Electrical Specifications table. This value increases with junction temperature and decreases slightly at lower currents. The typical V_F is lower, but design margins must use the 1.30 V max for worst-case thermal and loss calculations.

Does ES2G-T have a defined reverse recovery time (t_rr)?

Yes, the ES2G-T has a specified reverse recovery time of 35 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is critical for high-frequency switching efficiency and EMI control. The t_rr is confirmed in the Electrical Specifications section of the D2305 datasheet and distinguishes ES2G-T from standard fast rectifiers (>100 ns).

What package type does ES2G-T use, and is it compatible with automated assembly?

The ES2G-T uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads qualified per J-STD-002 for solderability. Its dimensions and lead finish are fully compatible with standard reflow profiles and automated pick-and-place equipment. The marking "ES2G" and cathode band provide clear orientation for vision-guided placement systems.

Is ES2G-T RoHS and halogen-free compliant?

Yes, the ES2G-T is both RoHS compliant and halogen-free, as explicitly stated in the FEATURES section of the D2305 datasheet. These compliance attributes are verified per JEDEC and IPC standards and apply to the entire device-including molding compound, die attach, and lead finish-ensuring suitability for environmentally regulated markets including EU and China RoHS.
