Product details

Overview

ES2J from Taiwan Semiconductor is a 2 A, 600 V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 1.70 V forward voltage at 2 A and 25°C, and 50 A surge current capability - deployed in snubber networks and high-frequency DC/DC converters.

For engineers reviewing the ES2J datasheet, ES2J pinout, ES2J application, or ES2J equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop at rated current, thermal resistance (R_θJL = 20°C/W), junction capacitance (20 pF), and moisture sensitivity level (MSL 1).

Technical Context

The ES2J is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency switching applications. Its 600 V V_RRM, 35 ns trr, and low Q_rr enable reduced switching losses in SMPS operating above 50 kHz.

Designed for automated SMT assembly, it uses matte tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AA (SMB) molded case.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 VAC line-fed offline converters without derating
I_F	2 A continuous - suitable for mid-power secondary-side rectification in 25–50 W DC/DC stages
t_rr	35 ns - enables operation up to ~300 kHz with minimal reverse recovery loss
V_F	1.70 V @ 2 A, 25°C - contributes ~3.4 W conduction loss at full load, requiring thermal management
R_θJL	20 °C/W - allows direct heat transfer to PCB copper, supporting >1.5 W dissipation with 30 mm² 2-oz copper pad
C_J	20 pF @ 4 V - limits capacitive coupling noise in high-dv/dt snubber and freewheeling paths

Pinout & Package

DO-214AA (SMB) surface-mount package: 2-terminal, single-anode/cathode configuration; molded UL 94V-0 compound; cathode indicated by band; weight ≈ 0.090 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Positive input terminal for forward conduction	Connected to lower-potential node (e.g., switch node in buck freewheel path)
Cathode	Negative output / reverse-blocking terminal	Marked by band; ties to output rail or ground return; blocks 600 V reverse stress

Key Features

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	V_F = 1.7 V @ 2 A (same); t_rr = 30 ns (5 ns faster); R_θJA = 65°C/W (vs. 75°C/W)	Slightly better thermal performance and marginally faster recovery	Preferred where board space permits TO-220AC or where tighter t_rr tolerance is required
SS26	V_RRM = 60 V only; Schottky architecture; V_F = 0.75 V; no reverse recovery	Lower loss but unsuitable for 600 V blocking - limited to low-voltage DC/DC	Only viable in sub-100 V systems where ultra-low V_F outweighs voltage limitation

Compared with STTH2R06 and SS26, the ES2J uniquely balances 600 V capability, SMB footprint, and MSL 1 compatibility - making it optimal for cost-sensitive, high-volume SMT designs requiring robust 600 V super fast rectification without leaded packages or voltage compromise.

FAQ

What is the maximum junction temperature rating for ES2J?

The ES2J has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings in the official TSC datasheet (Version L2102). This rating applies under steady-state conditions with appropriate PCB thermal design. Operation beyond this limit risks permanent degradation of the glass-passivated junction. Derating curves in Figure 1 confirm usable current drops to ~1.2 A at 125°C ambient with standard SMB pad layout.

Does ES2J have a halogen-free construction?

Yes, the ES2J is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the "Features" section of the TSC datasheet (Version L2102). The molding compound contains no bromine, chlorine, or other regulated halogens, supporting compliance with environmental directives for industrial and consumer end equipment shipped globally.

What is the reverse recovery time (t_rr) specification for ES2J?

The ES2J has a reverse recovery time (t_rr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table in the TSC ES2A–ES2J datasheet (Version L2102). This value is typical and guaranteed not to exceed 35 ns, enabling reliable use in 200–300 kHz switching applications.

Is ES2J compatible with lead-free reflow soldering processes?

Yes, the ES2J features matte tin-plated leads qualified per J-STD-002 for solderability and is rated MSL Level 1 per J-STD-020 - meaning it has unlimited floor life and withstands standard lead-free reflow profiles (peak 260°C) without baking. The DO-214AA (SMB) package is fully compatible with Type 3 and Type 4 solder pastes.

What does the "J" suffix indicate in ES2J?

The "J" suffix in ES2J denotes the 600 V repetitive peak reverse voltage (V_RRM) rating, as defined in the Absolute Maximum Ratings table of the TSC ES2A–ES2J datasheet (Version L2102). Within the ES2x family, "J" is the highest-voltage variant, distinguishing it from ES2A (50 V), ES2B (100 V), and others - all sharing identical package, current rating, and recovery characteristics.
