Product details

Overview

ES2J-T from Taiwan Semiconductor is a 2 A, 600 V super fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 1.70 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 ES2J-T datasheet, ES2J-T pinout, ES2J-T application, or ES2J-T equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop under load, thermal resistance (R_θJL = 20°C/W), reverse recovery performance, and SMB package compatibility with automated SMT assembly.

Technical Context

The ES2J-T employs a glass-passivated silicon junction optimized for super-fast recovery (trr ≤ 35 ns), enabling efficient operation in DC–DC converters and SMPS operating above 50 kHz. Its 600 V V_RRM and 1.70 V V_F (max at 2 A, 25°C) reflect a design trade-off favoring high-voltage blocking over ultra-low conduction loss.

Thermally, it delivers R_θJL = 20°C/W and R_θJA = 75°C/W, supporting continuous 2 A operation with appropriate PCB copper area. The DO-214AA (SMB) package provides polarity indication via cathode band and meets J-STD-020 moisture sensitivity level 1.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse voltage; defines safe blocking capability in high-voltage DC bus or flyback secondary circuits.
I_F	2 A - Continuous average forward current; determines usable output current in rectifier applications with adequate heatsinking.
t_rr	35 ns - Reverse recovery time; enables stable operation in 100–500 kHz switching topologies with minimal switching loss.
V_F (max)	1.70 V @ 2 A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal rise in high-duty-cycle rectification.
I_FSM	50 A - Non-repetitive surge current (8.3 ms sine); supports inrush and transient overload handling without failure.
R_θJL	20 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper or heatsink via soldered leads.

Pinout & Package

Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode indicated by molded band. Lead finish: matte tin, solderable per J-STD-002; flammability rating UL 94V-0.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES2J-M3/5BT	Same 600 V V_RRM, 2 A I_F, but t_rr = 30 ns (typ), V_F = 1.65 V (max); DO-214AA package.	Slightly faster recovery and lower V_F; identical mounting and thermal profile.	Preferred where <5 ns trr reduction improves system efficiency or EMI margin.
ON Semiconductor MUR260G	600 V V_RRM, 2 A I_F, t_rr = 50 ns (max), V_F = 1.75 V (max); same DO-214AA package.	Slower recovery increases switching loss in >150 kHz designs; higher V_F raises conduction loss.	Acceptable for lower-frequency (<100 kHz) or cost-constrained designs where 15 ns slower trr is tolerable.

Compared with ES2J-T, VS-ES2J-M3/5BT offers marginal improvement in speed and forward drop, while MUR260G trades recovery performance for broader legacy support and slightly higher conduction loss-selection depends on operating frequency, thermal budget, and supply chain preference.

FAQ

What is the maximum junction temperature rating for the ES2J-T?

The ES2J-T has a maximum junction temperature (T_J) of +150°C, with an operational range from –55°C to +150°C. This rating allows reliable continuous operation at full 2 A forward current when PCB thermal design maintains junction temperature below this limit, supported by its 20°C/W junction-to-lead thermal resistance. Derating curves in the ES2J-T datasheet specify reduced current above 75°C ambient.

Does the ES2J-T have a halogen-free and RoHS-compliant construction?

Yes, the ES2J-T is both halogen-free and RoHS compliant, as confirmed in the official Taiwan Semiconductor product documentation. The molding compound, lead finish (matte tin), and internal materials meet EU RoHS Directive 2011/65/EU requirements and contain no brominated flame retardants or chlorine-based compounds, ensuring environmental compliance for global electronics manufacturing.

What is the reverse recovery time (t_rr) specification for the ES2J-T, and under what test conditions is it measured?

The ES2J-T reverse recovery time is 35 ns maximum, measured under the conditions: I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A, using a standardized test circuit per JEDEC standards. This value reflects the device's ability to rapidly transition from conduction to blocking state, critical for minimizing switching losses in high-frequency power converters where the ES2J-T is commonly deployed.

Can the ES2J-T be used as a direct replacement for the ES2G-T in an existing design?

No, the ES2J-T is not a direct replacement for the ES2G-T due to its higher 600 V V_RRM (vs. 400 V) and higher 1.70 V V_F (vs. 1.30 V). While pin-compatible and same-package, the increased forward voltage raises conduction loss, and the higher voltage rating does not improve performance unless the circuit requires >400 V blocking. System-level validation is required before substitution.

What is the marking code printed on the ES2J-T device body?

The ES2J-T is marked with "ES2J" on the device body, per Taiwan Semiconductor's ordering information table. This marking appears adjacent to the cathode band on the DO-214AA (SMB) package and is used for visual identification and traceability during assembly and inspection. No additional date or factory codes are part of the primary device marking for this variant.
