Product details

Overview

ES2JAL from Taiwan Semiconductor is a 2A, 600V super fast surface-mount rectifier in a Thin SMA package, featuring 1.24V forward voltage at 2A/25°C, 35ns reverse recovery time, and 21pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies requiring low conduction loss and fast recovery.

For engineers reviewing the ES2JAL datasheet, ES2JAL pinout, ES2JAL application, or ES2JAL equivalent, key selection criteria include its 600V V_RRM, 50A I_FSM surge rating, 150°C maximum junction temperature, and compatibility with automated SMT assembly on standard PCB pads.

Technical Context

The ES2JAL is a single-die, unidirectional silicon rectifier optimized for high-frequency operation up to several hundred kHz. Its super-fast recovery (t_rr ≤ 35ns) minimizes switching losses in DC-DC converters and inverters, while its glass-passivated junction ensures stable performance under thermal cycling and humidity stress.

Thermal design is supported by R_θJL = 24°C/W and R_θJA = 72°C/W (on 5mm × 5mm Cu pad), enabling reliable 2A continuous conduction at ambient temperatures up to 85°C without forced airflow. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

Applications

DC-DC Converter Output Rectification	Switching Inverter Freewheeling
Use Scenario: Secondary-side rectification in isolated 48V–60V output DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Unidirectional current steering diode converting transformer AC output to regulated DC; operates at 200–300 kHz switching frequency. Use Value: 600V V_RRM provides 2× safety margin over 300V reflected transient spikes; 1.24V V_F limits conduction loss to <1.5W at 2A.	Use Scenario: Freewheeling path across inductive loads (e.g., motor windings or PFC chokes) in half-bridge inverters. IC Role / Device Role / Timing Role: Clamp-inductive kickback during MOSFET turn-off; conducts only during dead-time intervals with sub-50ns transition. Use Value: 35ns t_rr prevents reverse recovery current overlap with high-side switch, reducing shoot-through risk and EMI.
High-Voltage Auxiliary Supply	Industrial AC-DC Adapter Input Stage
Use Scenario: Bias supply rectification in >400V DC-link auxiliary rails for gate drivers and controllers in EV chargers. IC Role / Device Role / Timing Role: Primary rectifier feeding linear or buck regulator for control IC bias; operates continuously at 1–2A. Use Value: 150°C T_JMAX and 24°C/W R_θJL allow stable 2A operation on minimal copper, reducing heatsink dependency.	Use Scenario: Input bridge rectifier replacement in universal-input (90–264V AC) industrial adapters targeting 600V system derating. IC Role / Device Role / Timing Role: Single-diode element in discrete bridge configuration; handles peak line voltages up to 375V DC after rectification. Use Value: 600V V_RRM exceeds 375V peak + 100V margin; 50A I_FSM withstands cold-start inrush surges without degradation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES2J-M3/5BT	Same 600V V_RRM, 2A I_F, but t_rr = 30ns (5ns faster); VF = 1.25V @ 2A/25°C; Thin SMA package.	Slightly lower switching loss in >300kHz designs; identical mounting and footprint.	Preferred where minimum t_rr is prioritized over cost; no PCB change required.
ON Semiconductor MUR260RLG	600V V_RRM, 2A I_F, but t_rr = 50ns (15ns slower); VF = 1.2V @ 2A/25°C; DO-204AC (SMA) package, not Thin SMA.	Higher reverse recovery loss; larger package height (2.7mm vs. 2.3mm) may affect board clearance.	Acceptable where layout tolerates taller profile and 50ns t_rr meets system EMI targets.

Compared with VS-ES2J-M3/5BT and MUR260RLG, the ES2JAL offers balanced trade-offs: tighter t_rr than MUR260RLG for better high-frequency efficiency, and lower VF than VS-ES2J-M3/5BT at elevated temperature-making it optimal for thermally constrained 200–250kHz industrial converters.

FAQ

What is the maximum junction temperature rating for ES2JAL?

The ES2JAL has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings in the official TSC datasheet Version D2103. This rating allows continuous 2A operation in ambient temperatures up to 85°C when mounted on a 5mm × 5mm copper pad, leveraging its 24°C/W junction-to-lead thermal resistance. Derating curves confirm usable current down to 0A at 150°C ambient.

Does ES2JAL support automated SMT assembly?

Yes, ES2JAL supports automated surface-mount assembly. Its Thin SMA package features matte tin-plated leads compliant with J-STD-002 solderability standards, and its moisture sensitivity level is rated Class 1 per J-STD-020-meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. The low-profile geometry also ensures stable placement during high-speed pick-and-place.

What is the reverse recovery time (t_rr) specification for ES2JAL?

The ES2JAL reverse recovery time is specified as ≤35 ns under test conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A, per the Electrical Specifications table in the TSC ES2xAL datasheet. This value is measured at 25°C and remains stable across the –55°C to +125°C junction temperature range, making ES2JAL suitable for high-frequency switching applications above 100 kHz.

How does the forward voltage of ES2JAL compare at elevated temperature?

At 2A and 125°C junction temperature, the ES2JAL forward voltage is 1.01V (typ) and 1.14V (max), which is significantly lower than its 25°C value of 1.24V (typ)/1.70V (max). This negative temperature coefficient improves thermal stability in high-power-density designs, reducing runaway risk and enabling higher current capability at elevated operating temperatures.

Is ES2JAL RoHS and halogen-free compliant?

Yes, ES2JAL is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These compliance statements are explicitly confirmed in the FEATURES section of the official TSC ES2xAL datasheet (Version D2103), and the device carries appropriate markings and documentation for use in environmentally regulated industrial and computing equipment.
