Product details
Overview
S2JA-13 from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode rated for 600 V peak repetitive reverse voltage (VRRM), 1.5 A average forward current (I(AV)) at 100°C terminal temperature, and 50 A non-repetitive surge current (IFSM), used as a primary AC/DC input rectifier in offline power supplies and DC link circuits.
For engineers reviewing the S2JA-13 datasheet, S2JA-13 pinout, S2JA-13 application, or S2JA-13 equivalent, key selection considerations include its 1.15 V forward voltage at 1.5 A, 5 µA max reverse leakage at 25°C, 20 pF junction capacitance, thermal resistance of 20 °C/W, and SMA package compatibility with automated reflow assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz line-frequency conditions with resistive or inductive loads; capacitive loads require 20% current derating. Its glass passivated die construction ensures stable reverse characteristics across -65°C to +150°C operating range.
The diode exhibits low forward conduction loss (VFM = 1.15 V @ IF = 1.5 A) and robust surge capability (50 A IFSM, 8.3 ms half-sine), making it suitable for transient-heavy industrial and appliance power inputs where thermal management relies on PCB copper pads per JEDEC mounting guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage rating (e.g., 400 VAC RMS systems). |
| I(AV) | 1.5 A @ TT = 100°C - Continuous DC output current capability when mounted on 5.0 mm² copper pad heat sink. |
| VFM | 1.15 V @ IF = 1.5 A - Forward conduction loss directly impacts efficiency and thermal rise in linear rectification stages. |
| IFSM | 50 A, 8.3 ms - Surge withstand level for cold-start inrush or lightning-induced transients in mains-connected equipment. |
| IRM | 5.0 µA @ 25°C, 600 V - Low leakage preserves hold-up capacitor charge and minimizes standby power loss. |
| RJT | 20 °C/W - Junction-to-terminal thermal resistance determines required PCB copper area for thermal compliance. |
| CT | 20 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency noise coupling and EMI filter design in switching converters. |
Pinout & Package
Package: SMA (Surface-Mount Axial), molded plastic case, UL 94V-0 rated, cathode marked by band or notch. Dimensions: A = 2.29–2.92 mm, B = 4.00–4.60 mm, C = 1.27–1.63 mm, E = 4.80–5.59 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for AC or positive half-cycle | Connected to transformer secondary or bridge input; must handle full surge current and RMS current. |
| Cathode | Output terminal for rectified DC | Marked with band; connects to bulk capacitor or downstream regulator; polarity critical for circuit function. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable reverse leakage performance and long-term reliability under humidity and thermal cycling. |
| Low VFM (1.15 V) | Reduces conduction loss by ~15% vs. standard 1N4007 in same 1.5 A load, lowering heatsink requirements. |
| 50 A IFSM rating | Supports direct connection to unfiltered AC mains without external NTC thermistor in cost-sensitive designs. |
| SMA package | Compatible with standard SMT reflow profiles and automated pick-and-place; footprint matches industry-standard DO-214AC. |
Applications
| Industrial Power Supply Input | Appliance Motor Control Rectification |
|---|---|
Use Scenario: AC line input stage of 24–48 V DC industrial power supply feeding PLC I/O modules. IC Role / Device Role / Timing Role: Primary rectifier converting 115/230 VAC to unregulated DC bus prior to buck converter regulation. Use Value: 600 V VRRM provides 2× safety margin over 230 VAC peak (325 V), while 1.5 A I(AV) supports up to 36 W continuous output. | Use Scenario: Half-wave rectification for speed control circuit in washing machine motor driver. IC Role / Device Role / Timing Role: Converts phase-controlled AC to pulsed DC for TRIAC gate drive or DC link charging. Use Value: 50 A IFSM withstands motor startup surges; glass passivation prevents leakage drift during high-humidity operation. |
| LED Driver Bulk Capacitor Charging | IoT Gateway AC-DC Adapter |
Use Scenario: Charging bulk electrolytic capacitor in non-isolated LED driver for street lighting. IC Role / Device Role / Timing Role: Rectifies 120 VAC input to maintain minimum hold-up voltage during line sags. Use Value: 20 pF CT minimizes high-frequency noise injection into sensitive LED current regulation loop. | Use Scenario: Compact wall adapter powering 5 V/1 A IoT gateway with space-constrained PCB layout. IC Role / Device Role / Timing Role: Input rectifier in flyback-derived SMPS with integrated controller. Use Value: SMA package enables 30% smaller footprint than SMB variant while maintaining 1.5 A thermal rating via optimized copper pour. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | Ultrafast recovery (75 ns), higher VRRM (600 V), same I(AV) (1.5 A), TO-220AC package | Requires through-hole mounting and heatsink; unsuitable for high-density SMT layouts | Select when fast recovery is needed to reduce EMI in high-frequency SMPS, not for basic rectification. |
| Vishay VS-1N5408TR | Standard recovery (2 µs), lower VRRM (1000 V), same I(AV) (3 A), DO-204AL axial lead | Through-hole only; higher current but larger size and no RoHS-compliant lead-free option | Choose for legacy repair or high-voltage, low-frequency applications where SMT is not required. |
Compared with S2JA-13, MUR160 offers faster switching at the cost of board space and assembly complexity, while VS-1N5408TR delivers higher voltage margin and current but lacks SMT compatibility and modern thermal performance on PCBs.

FAQ
What is the maximum allowable PCB copper pad area for thermal compliance of S2JA-13?
The datasheet specifies thermal resistance RJT = 20 °C/W when mounted on 5.0 mm² of 0.013 mm thick copper pad. Increasing pad area beyond this reduces thermal resistance incrementally, but 5.0 mm² is the validated baseline for 1.5 A continuous operation at 100°C terminal temperature.
Can S2JA-13 be used in full-wave bridge configurations?
Yes - S2JA-13 is a single diode and can be used in discrete full-wave bridge designs. Four units are required per bridge. It is not a pre-assembled bridge; each device must be placed individually with correct anode/cathode orientation per leg.
Does S2JA-13 have a lead-free finish?
Yes - S2JA-13 is supplied with a matte tin lead-free plating and complies with RoHS Directive 2002/95/EC (as revised March 13, 2003), including exemptions for glass passivation and high-temperature solder per EU Annex Notes 5 and 7.
How does capacitive loading affect S2JA-13's current rating?
Capacitive loading requires 20% derating of I(AV). For example, at full-rated 1.5 A average current with resistive load, the maximum allowable current drops to 1.2 A when charging large input capacitors, due to increased peak current stress and reduced conduction angle.
