Product details

Overview

ES1J-T from Taiwan Semiconductor is a 1A, 600V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 1.70V max forward voltage at 1A and 35ns reverse recovery time. It serves as a freewheeling or output rectifier in high-frequency switching power supplies requiring low conduction loss and rapid turn-off.

For engineers reviewing the ES1J-T datasheet, ES1J-T pinout, ES1J-T application, or ES1J-T equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop at rated current, thermal resistance (R_θJA = 85°C/W), junction temperature limit (+150°C), and moisture sensitivity level (MSL 1).

Technical Context

The ES1J-T employs a glass-passivated silicon junction optimized for super-fast recovery (t_rr ≤ 35 ns), enabling efficient operation in DC–DC converters and SMPS operating above 50 kHz. Its single-die configuration and DO-214AC package support automated placement and reflow soldering per J-STD-002.

With V_RRM = 600 V, I_F = 1 A, and I_FSM = 30 A (8.3 ms half-sine), the device targets medium-power switching applications where reverse leakage (< 5 µA @ 25°C) and low junction capacitance (18 pF @ 1 MHz, 4 V) reduce switching losses and EMI.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse blocking voltage; defines usable input/output voltage range in flyback or boost topologies.
V_F (max)	1.70 V @ 1 A, 25°C - Directly impacts conduction loss and thermal rise in continuous-current rectification paths.
t_rr	35 ns - Enables high-frequency switching (>100 kHz) with minimal reverse recovery charge and associated switching loss.
I_FSM	30 A - Withstands short-duration surge currents during startup or fault conditions without permanent degradation.
R_θJA	85 °C/W - Determines required PCB copper area and airflow for thermal management at full load in enclosed environments.
Junction Temp	−55°C to +150°C - Supports operation in industrial ambient conditions and allows derating for reliability over lifetime.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry point during forward conduction	Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary center-tap).
Cathode	Current exit point during forward conduction; marked by band	Connected to output filter capacitor or load return; polarity must be observed to prevent reverse breakdown.

Key Features

Feature	Design Value
Glass passivated junction	Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in non-hermetic assemblies.
MSL Level 1	Zero floor life limitation-no baking required before SMT reflow, reducing manufacturing overhead and risk of moisture-induced popcorning.
RoHS & halogen-free	Complies with IEC 61249-2-21 and EU RoHS Directive; enables use in environmentally regulated industrial and consumer products.
Super fast t_rr	35 ns recovery minimizes reverse recovery current spikes, lowering EMI generation and improving efficiency in >50 kHz converters.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06U	Same 600 V V_RRM, but 1.25 V V_F (typ) at 1 A; t_rr = 30 ns; TO-277 package (smaller footprint than SMA)	Lower forward drop improves efficiency in thermally constrained designs; different thermal path due to DPAK-like leadframe	Preferred when board space is limited and thermal interface to copper pour is optimized for TO-277.
MBR160-E3/5BT	Schottky structure: 60 V V_RRM, 0.55 V V_F; no reverse recovery (t_rr ≈ 0); higher leakage (≤500 µA @ 25°C)	Not suitable for 600 V bus applications; only viable in low-voltage secondary-side or OR-ing circuits	Select only for sub-100 V systems where ultra-low V_F outweighs voltage limitation and leakage sensitivity.

Compared with STTH1R06U and MBR160-E3/5BT, the ES1J-T offers the highest voltage rating among the three, making it uniquely suitable for universal-input offline SMPS and industrial inverters-while trading off slightly higher V_F for robustness and cost-effective DO-214AC manufacturability.

FAQ

What is the maximum junction temperature rating for the ES1J-T?

The ES1J-T has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet F2111. This allows reliable operation in industrial ambient environments up to +85°C when properly mounted on ≥1 cm² of 2-oz copper with adequate airflow. Derating curves in Figure 1 confirm 1 A average current is sustainable at 100°C case temperature.

Does the ES1J-T have a specified reverse recovery time, and how is it measured?

Yes, the ES1J-T specifies a maximum reverse recovery time (t_rr) of 35 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, per the electrical specifications section of the TSC F2111 datasheet. This value reflects actual switching behavior in high-frequency converters and is not extrapolated from other variants in the ES1x-T series.

Is the ES1J-T compatible with lead-free reflow soldering processes?

Yes, the ES1J-T features matte tin-plated leads qualified per J-STD-002 for solderability and meets JEDEC JESD201 Class 1A whisker resistance requirements. Its DO-214AC package is rated for standard Pb-free reflow profiles (peak 260°C, 10 sec max), and its MSL Level 1 classification means no pre-bake is required prior to assembly.

What does the "J" in ES1J-T signify, and how does it differ from ES1G-T?

The "J" in ES1J-T designates its 600 V repetitive peak reverse voltage (V_RRM) rating, per TSC's ordering code convention where "x" maps to voltage grade (D=200V, G=400V, J=600V). Compared to ES1G-T (400 V), the ES1J-T provides 200 V higher blocking capability but exhibits higher forward voltage (1.70 V vs. 1.30 V max at 1 A) due to wider depletion region design.

Can the ES1J-T be used as a direct replacement for ES1D-T in an existing design?

No-the ES1J-T is not a direct replacement for ES1D-T due to its higher V_RRM (600 V vs. 200 V) and higher V_F (1.70 V vs. 0.95 V max). While both share DO-214AC packaging and pinout, substituting ES1J-T may increase conduction loss and alter thermal behavior; redesign validation-including voltage margin checks and thermal imaging-is required before implementation.
