Product details
Overview
ES2JA-T from Taiwan Semiconductor is a 2 A, 600 V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 1.44 V forward voltage at 2 A and 25°C, 35 ns reverse recovery time, and 11 pF junction capacitance - optimized for high-frequency switching in DC/DC converters and freewheeling paths.
For engineers reviewing the ES2JA-T datasheet, ES2JA-T pinout, ES2JA-T application, or ES2JA-T equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 14 °C/W), low leakage (<5 µA @ 25°C), and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
The ES2JA-T employs a single-die, glass-passivated silicon junction to achieve super-fast recovery (trr ≤ 35 ns) while sustaining 600 V repetitive peak reverse voltage (VRRM). Its low junction capacitance (11 pF at 1 MHz, 4 V) minimizes switching losses in high-frequency topologies.
Thermally, it delivers RθJL = 14 °C/W and RθJA = 86 °C/W when mounted on a 5 mm × 5 mm Cu pad, enabling reliable operation up to TJ = 150 °C under continuous 2 A forward current with appropriate board layout.
Key Specifications

| VRRM | 600 V - supports primary-side rectification in offline SMPS with ≥340 V DC bus |
| IF | 2 A continuous - rated for sustained conduction in compact power stages |
| trr | ≤35 ns - enables efficient operation at ≥100 kHz switching frequencies |
| VF @ 2 A, 25°C | 1.44 V (max 1.70 V) - defines conduction loss and thermal load in high-current paths |
| CJ | 11 pF @ 1 MHz, 4 V - reduces capacitive coupling and EMI in fast-switching nodes |
| IR @ VR, 25°C | ≤5 µA - ensures minimal leakage in high-impedance hold-up or sensing circuits |
| RθJL | 14 °C/W - allows direct thermal path to PCB copper, simplifying heatsinking |

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 | Same 2 A / 600 V rating; trr = 30 ns (slightly faster); VF = 1.55 V @ 2 A, 25°C (higher) | Marginally better recovery but higher conduction loss; requires identical DO-214AC layout | Prefer when minimizing switching loss dominates over thermal budget |
| MBR260 | Schottky type, 2 A / 60 V max - not voltage-compatible; VF = 0.72 V @ 2 A | Limited to low-voltage DC/DC; unsuitable for 600 V applications like offline SMPS | Select only for sub-100 V systems where ultra-low VF outweighs voltage limitation |
Compared with STTH2R06 and MBR260, the ES2JA-T offers optimal balance of 600 V capability, 35 ns recovery, and manufacturability in high-volume SMT lines - making it preferred for cost-sensitive, thermally constrained industrial power supplies where voltage rating and reliability are non-negotiable.

FAQ
What is the maximum junction temperature rating for the ES2JA-T?
The ES2JA-T has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings in the official datasheet. This allows continuous operation in demanding environments such as enclosed industrial power supplies or motor drives. Derating curves confirm usable current capacity down to 1.2 A at 125 °C ambient with standard PCB cooling. The ES2JA-T must be operated within this limit to ensure long-term reliability and avoid parametric shift.
Does the ES2JA-T support automated pick-and-place assembly?
Yes, the ES2JA-T is explicitly designed for automated placement, as confirmed in its features list and mechanical data. Its DO-214AC (SMA) package, matte tin-plated leads, and MSL Level 1 rating per J-STD-020 enable compatibility with standard SMT reflow processes without pre-baking. The device's 0.060 g weight and symmetrical geometry further ensure stable feeding and placement accuracy in high-speed pick-and-place machines used in volume manufacturing of the ES2JA-T.
What is the reverse recovery time (trr) specification for the ES2JA-T?
The ES2JA-T has a reverse recovery time (trr) of ≤35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is specified in the Electrical Specifications table and confirmed across multiple test points in the Characteristics Curves section. The 35 ns trr directly enables efficient operation in switching power supplies above 100 kHz, distinguishing the ES2JA-T from standard recovery diodes and supporting reduced EMI and improved efficiency in the ES2JA-T's target applications.
Is the ES2JA-T halogen-free and RoHS compliant?
Yes, the ES2JA-T is both halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the FEATURES section of the official documentation. These compliance statements apply specifically to the ES2JA-T variant and are verified through material declarations and third-party testing. This makes the ES2JA-T suitable for export to EU, China, and other regulated markets where substance restrictions apply, and aligns with environmental policies for industrial and commercial electronics using the ES2JA-T.
What is the marking code printed on the ES2JA-T device body?
The ES2JA-T is marked with "ES2JA" on its body, as shown in the Marking Diagram and confirmed in the Absolute Maximum Ratings table where "Marking code on the device" is explicitly listed as ES2JA for the ES2JA-T variant. This marking is laser-etched or molded onto the DO-214AC package and serves as the primary visual identifier for traceability, counterfeit prevention, and field verification - ensuring unambiguous identification of the ES2JA-T in production and repair workflows.
