Product details
Overview
S2JA-T from Taiwan Semiconductor is a 2 A, 600 V standard surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, low reverse leakage (≤5 µA at 25°C), and 150°C maximum junction temperature. It is used in DC-DC converters and switching-mode inverters requiring reliable mid-voltage rectification.
For engineers reviewing the S2JA-T datasheet, S2JA-T pinout, S2JA-T application, or S2JA-T equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage (0.96 V max at 2 A, 25°C), thermal resistance (RθJL = 14 °C/W), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The S2JA-T is a single-die, unidirectional standard recovery rectifier with a glass-passivated PN junction optimized for automated SMT assembly. Its 600 V VRRM rating and 50 A IFSM (8.3 ms) support robust surge handling in switching power supplies.
Thermal performance is characterized on a 5 mm × 5 mm copper pad PCB: RθJA = 86 °C/W and RθJC = 23 °C/W confirm suitability for moderate-power board-level thermal management without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 400–600 V DC bus applications. |
| IF | 2 A continuous - Rated average forward current at case temperature ≤75°C; supports sustained conduction in compact SMPS designs. |
| VF | 0.96 V max at 2 A, 25°C - Low forward drop reduces conduction loss and improves efficiency in high-frequency rectification stages. |
| IR | 5 µA max at 600 V, 25°C - Minimal leakage preserves regulation stability and minimizes standby power loss. |
| TJ max | +150°C - Enables operation in thermally constrained environments such as enclosed power adapters or motor drives. |
| CJ | 30 pF at 4 V - Junction capacitance impacts high-frequency switching noise and EMI filter design in >100 kHz converters. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration. Cathode indicated by molded band. Matte tin-plated leads, J-STD-002 solderable, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to lower-potential side of AC input or transformer secondary; must withstand full surge current (IFSM = 50 A). |
| Cathode (K) | Forward current exit point | Connected to output capacitor or load; polarity marking ensures correct orientation during automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial-grade assemblies. |
| Low IR (≤5 µA @ 25°C) | Reduces standby power dissipation and prevents unintended biasing in multi-rail systems with shared ground references. |
| RoHS & halogen-free | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; enables compliance in export-oriented consumer and industrial products. |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; supports direct use in standard SMT lines without process modification. |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–48 V output. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer secondary into regulated DC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; faster recovery time (trr = 50 ns vs. ~1.5 µs for S2JA-T); higher VF (1.15 V typ) | Better suited for high-frequency (>100 kHz) SMPS where reverse recovery loss dominates | Select STTH2R06 when minimizing switching loss is critical; S2JA-T preferred for cost-sensitive, thermally constrained 20–60 kHz designs |
| ES2J | Same DO-214AC package; identical VRRM and IF; slightly higher VF (0.98 V max) and IR (10 µA) | Functionally interchangeable in general-purpose rectification with minor efficiency trade-off | ES2J offers second-source availability; S2JA-T provides lower leakage and tighter VF tolerance for precision regulation |
Compared with STTH2R06 and ES2J, the S2JA-T delivers the lowest reverse leakage and best thermal resistance (RθJL = 14 °C/W), making it optimal for ambient-temperature-sensitive industrial power supplies where long-term reliability outweighs ultra-fast switching needs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S2JA-T?
The S2JA-T has a VRRM of 600 V, verified per Taiwan Semiconductor's D2111 datasheet. This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is confirmed across all production lots. The S2JA-T must not be operated above this voltage in continuous or repetitive conditions to ensure long-term reliability.
Does the S2JA-T meet RoHS and halogen-free requirements?
Yes, the S2JA-T is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the official Taiwan Semiconductor documentation. These compliance attributes are built into the molding compound and plating process, and full test reports are available upon request for S2JA-T production lots.
What is the forward voltage (VF) of the S2JA-T at 2 A and 25°C?
The S2JA-T exhibits a maximum forward voltage of 0.96 V at 2 A and 25°C, with typical value of 0.90 V. This specification is measured under pulsed conditions (PW = 0.3 ms) and is critical for calculating conduction losses in power supply designs using the S2JA-T.
Is the S2JA-T suitable for automated SMT assembly?
Yes, the S2JA-T is explicitly designed for automated placement, with moisture sensitivity level 1 (per J-STD-020), matte tin-plated leads compliant with J-STD-002, and DO-214AC (SMA) package geometry optimized for pick-and-place accuracy. No pre-bake is required before reflow soldering of the S2JA-T.
What is the junction-to-lead thermal resistance (RθJL) of the S2JA-T?
The S2JA-T has a typical junction-to-lead thermal resistance of 14 °C/W, measured on a standard 5 mm × 5 mm copper pad PCB. This value enables accurate thermal modeling when the S2JA-T is mounted directly to a PCB without additional heatsinking, supporting thermal design validation for the S2JA-T in real-world layouts.
