Product details
Overview
S2J from Taiwan Semiconductor is a 600 V, 2 A standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 50 A surge capability, 1.15 V max forward voltage at 2 A, and 1 µA max reverse leakage at 25°C - used in AC/DC front-end rectification for industrial SMPS and LED drivers.
For engineers reviewing the S2J datasheet, S2J pinout, S2J application, or S2J equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (RθJL = 16 °C/W), junction capacitance (30 pF), reverse recovery time (1500 ns), and moisture sensitivity level (MSL 1).
Technical Context
The S2J is a single-die, glass-passivated standard recovery rectifier optimized for cost-sensitive, medium-voltage power conversion. Its 600 V VRRM rating and 50 A IFSM support robust line-input rectification under transient overloads.
Designed for automated placement and reflow soldering, it meets J-STD-002 for solderability and JESD 201 Class 2 for tin whisker resistance. Polarity is marked by a cathode band on the DO-214AA body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage before breakdown; defines safe AC input voltage derating margin in bridge or single-phase rectifiers |
| IF | 2 A continuous - average forward current rating at TL = 75°C; determines heatsink-free operation in low-power adapters |
| IFSM | 50 A (8.3 ms half-sine) - surge withstand capability; enables reliable startup into capacitive loads without fuse tripping |
| VF | ≤1.15 V @ 2 A, 25°C - forward conduction loss directly impacts efficiency and thermal rise in high-duty-cycle applications |
| RθJL | 16 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour cooling without external heatsink |
| trr | 1500 ns - reverse recovery time; limits switching frequency suitability to ≤100 kHz in hard-switched topologies |
Pinout & Package
DO-214AA (SMB) surface-mount package with molded epoxy case (UL 94V-0), matte tin-plated leads, and cathode polarity indicated by a band on the cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal | Connected to AC source or transformer secondary; must handle full RMS current and surge peaks |
| Cathode | Rectified output terminal | Feeds bulk capacitor or downstream converter; polarity band ensures correct orientation during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in unsealed industrial enclosures |
| MSL Level 1 rating | Enables unlimited floor life and standard reflow without baking prior to assembly |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives for green manufacturing and end-of-life recycling |
| Low RθJL (16 °C/W) | Permits >1.5 W power dissipation with minimal PCB copper area, reducing layout cost |
Applications
| Industrial SMPS Input Rectification | LED Driver Bulk Rectification |
|---|---|
Use Scenario: Single-phase AC input stage of 30–60 W industrial switch-mode power supplies operating at 50/60 Hz. IC Role / Device Role / Timing Role: Standard recovery rectifier converting AC line to DC bus; not a timing or control device. Use Value: 600 V VRRM provides 2× safety margin over 230 VAC RMS, while 50 A IFSM handles cold-start surges without degradation. | Use Scenario: Off-line LED driver for street lighting or commercial fixtures with universal AC input (90–305 VAC). IC Role / Device Role / Timing Role: Primary-side rectifier feeding bulk capacitor; operates in continuous conduction mode. Use Value: 1.15 V VF minimizes conduction loss at 2 A average current, improving system efficiency by ~0.8% vs. higher-VF alternatives. |
| AC/DC Adapter Output Stage | DC-DC Converter Input Protection |
Use Scenario: Secondary-side rectification in 12–24 V, 2 A wall adapters for industrial sensors and controllers. IC Role / Device Role / Timing Role: Uncontrolled rectifier in center-tapped or voltage-doubler configuration. Use Value: DO-214AA footprint enables compact board layout; MSL Level 1 eliminates pre-bake steps in high-volume SMT lines. | Use Scenario: Reverse-polarity and back-EMF protection at input of isolated DC-DC modules in battery-powered equipment. IC Role / Device Role / Timing Role: Blocking diode preventing damage from accidental reverse connection or inductive kickback. Use Value: 1 µA max IR at 25°C ensures negligible standby leakage; 150°C TJMAX supports operation in sealed enclosures up to 85°C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06U (STMicroelectronics) | Same VRRM (600 V), lower VF (0.95 V typ), faster trr (75 ns), TO-277A package | Better efficiency and EMI in high-frequency PFC stages; requires different footprint and thermal pad design | Select when optimizing for <100 kHz switching or tighter thermal constraints |
| ES2J (ON Semiconductor) | Identical VRRM, IF, package (DO-214AA), but higher VF (1.7 V max) and slower trr (2.5 µs) | Higher conduction loss and greater switching noise; suitable only where cost is primary constraint | Select only if legacy BOM compatibility or lowest unit cost is mandatory |
Compared with STTH2R06U and ES2J, the S2J delivers balanced performance: lower VF than ES2J for better efficiency, and superior surge rating (50 A vs. 30 A) versus STTH2R06U - making it optimal for ruggedized, medium-frequency industrial rectification where reliability and thermal margin outweigh ultra-low-loss requirements.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the S2J?
The S2J has a VRRM of 600 V, verified per Taiwan Semiconductor's N2102 datasheet. This rating defines the highest instantaneous reverse voltage the diode can block repeatedly without breakdown. It supports safe operation across 230 VAC mains with appropriate derating and is confirmed in the Absolute Maximum Ratings table for the S2J marking code row.
Does the S2J have a specified reverse recovery time (trr)?
Yes, the S2J has a typical reverse recovery time of 1500 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is explicitly listed in the Electrical Specifications table and confirms its classification as a standard (not fast or ultrafast) recovery rectifier, limiting its use to frequencies below ~100 kHz.
Is the S2J compliant with RoHS and halogen-free standards?
Yes, the S2J is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. These compliance statements apply specifically to the S2J variant and are verified through TSC's material declarations and third-party testing reports.
What is the thermal resistance from junction to lead (RθJL) for the S2J?
The S2J has a typical junction-to-lead thermal resistance (RθJL) of 16 °C/W, published in the Thermal Performance section. This parameter enables accurate thermal modeling when using PCB copper as a heatsink and is measured under standardized test conditions per JESD51-14.
What does the "S2J" marking code indicate on the device body?
The "S2J" marking code identifies the specific voltage grade within the S2x family - corresponding to 600 V VRRM. Per the Absolute Maximum Ratings table, S2J is the only variant assigned 600 V in the S2A–S2V series, and this marking is laser-etched or printed on the DO-214AA package body per JEDEC standards.
