Product details
Overview
ES2JA from Taiwan Semiconductor is a 2A, 600V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 1.70V max forward voltage at 2A/25°C, 35ns reverse recovery time, and 20pF junction capacitance - deployed in high-frequency snubber and freewheeling circuits within DC-DC converters.
For engineers reviewing the ES2JA datasheet, ES2JA pinout, ES2JA application, or ES2JA equivalent, key selection criteria include peak repetitive reverse voltage (600V), surge current rating (50A), thermal resistance (RθJL = 20°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for automated SMT assembly in industrial power supplies.
Technical Context
The ES2JA operates as a single-die, unidirectional silicon rectifier optimized for high-switching-frequency power conversion. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in flyback and forward converter topologies, while the glass-passivated junction ensures stable leakage performance up to 125°C (IR ≤ 350µA).
Thermally, the DO-214AC (SMA) package delivers RθJL = 20°C/W and RθJA = 75°C/W, enabling 2A continuous conduction with minimal heatsinking in compact layouts. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications

|---|---|
| VRRM | 600 V - supports primary-side rectification in offline 400VDC bus applications without derating |
| IF | 2 A - rated average forward current at TL = 75°C, suitable for continuous conduction mode (CCM) operation |
| IFSM | 50 A - withstands 8.3ms half-sine surge, enabling robust startup and fault transient handling |
| VF @ 2A, 25°C | ≤1.70 V - low conduction loss improves efficiency in high-duty-cycle DC-DC stages |
| trr | ≤35 ns - reduces reverse recovery charge (Qrr) and EMI generation in >100kHz switching designs |
| CJ @ 1MHz, 4V | 20 pF - limits capacitive coupling noise in high-dv/dt gate-drive or snubber networks |
| TJ max | +150°C - allows operation in thermally constrained enclosures without active cooling |

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 2A/600V rating; trr = 35ns; VF = 1.7V; DO-214AC package; higher RθJA (85°C/W) | Slightly higher thermal resistance requires larger copper area for same power dissipation | Preferred where STMicroelectronics supply chain alignment is required; identical electrical interface |
| SS26 | Lower VRRM (60V); VF = 0.55V; Schottky architecture; no reverse recovery | Not suitable for 600V applications; limited to low-voltage DC-DC outputs | Only viable for sub-100V secondary-side rectification where ultra-low VF outweighs voltage limitation |
Compared with STTH2R06, ES2JA offers better thermal performance (RθJA = 75°C/W vs. 85°C/W) and tighter VF consistency; versus SS26, ES2JA enables 600V primary-side use but lacks Schottky's zero-recovery advantage below 100V.

FAQ
What is the maximum junction temperature rating for ES2JA?
The ES2JA has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows sustained operation in high-ambient environments such as enclosed industrial power supplies. Derating curves in the ES2JA datasheet confirm 2A average current remains valid up to 75°C lead temperature, supporting conduction in thermally dense PCB layouts without forced air cooling.
Does ES2JA have a specified reverse recovery time, and how is it measured?
Yes, ES2JA specifies a maximum reverse recovery time (trr) of 35ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per JEDEC test conditions. This value is confirmed across all production lots and is critical for minimizing switching losses in high-frequency converters. The 35ns trr is consistent with its super fast rectifier classification and distinguishes ES2JA from standard or fast recovery alternatives.
Is ES2JA compatible with lead-free reflow soldering processes?
Yes, ES2JA is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its MSL Level 1 rating per J-STD-020 permits unlimited exposure to ambient conditions before reflow. The DO-214AC (SMA) package withstands peak reflow temperatures up to 260°C for 10 seconds, satisfying IPC-J-STD-020D profile requirements for Pb-free assembly.
What does the "JA" suffix indicate in ES2JA?
The "JA" suffix in ES2JA designates the 600V repetitive peak reverse voltage (VRRM) variant within the ES2x family. Per Taiwan Semiconductor's ordering code, "x" maps to voltage grade: AA = 50V, BA = 100V, … JA = 600V. This suffix is laser-marked on the device body and corresponds to the exact VRRM, VR(RMS), and thermal performance data published for ES2JA in the official datasheet.
How does ES2JA's junction capacitance affect high-frequency circuit performance?
ES2JA exhibits a typical junction capacitance (CJ) of 20pF at 1MHz and 4V reverse bias. This low capacitance minimizes displacement current and dv/dt-induced turn-on in snubber and gate-drive isolation circuits. In practice, it reduces high-frequency ringing amplitude by ≥15% compared to rectifiers with >35pF CJ, improving EMI compliance in Class B power supplies without additional filtering.
