Product details
Overview
S2J-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 conversion element in offline power supplies and auxiliary power rails.
For engineers reviewing the S2J-13 datasheet, S2J-13 pinout, S2J-13 application, or S2J-13 equivalent, key selection criteria include its 1.15 V forward voltage at 1.5 A, 5 µA 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 thermal resistance (20 °C/W) when mounted on 5.0 mm² copper pads, enabling reliable conduction at full 1.5 A average current up to 100°C terminal temperature, and maintains <125 µA reverse current at 125°C under rated blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage the diode blocks without breakdown during normal AC line operation. |
| I(AV) | 1.5 A at TT = 100°C - Continuous DC output current capability with adequate PCB copper heatsinking. |
| IFSM | 50 A (8.3 ms half-sine) - Surge withstand for cold-start inrush or transient overloads in SMPS input stages. |
| VFM | 1.15 V @ IF = 1.5 A - Forward conduction loss directly impacting efficiency and thermal design in 12–24 V auxiliary supplies. |
| IRM | 5.0 µA @ 25°C, 125 µA @ 125°C - Reverse leakage defining standby power loss and high-temperature reliability margin. |
| CT | 20 pF @ 1 MHz, 4 V - Junction capacitance affecting EMI filtering design and high-frequency switching noise coupling. |
| RJT | 20 °C/W - Thermal resistance from junction to terminal, dictating minimum required PCB copper area for thermal management. |
Pinout & Package
Package: SMA (Surface-Mount Axial), molded plastic case per UL 94V-0, cathode identified by band marking. 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 | AC input connection point | Accepts incoming AC waveform; must be routed with clearance for 600 V working voltage. |
| Cathode | DC output connection point | Delivers rectified unidirectional current; polarity marking (band) ensures correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term stability of reverse leakage and breakdown voltage under humidity and thermal cycling. |
| Low VFM (1.15 V) | Reduces conduction loss by ~15% vs. standard 1N4007 in 1.5 A applications, lowering heatsink requirements. |
| 50 A IFSM rating | Supports robust startup in flyback and buck-derived auxiliary supplies without fuse coordination issues. |
| RoHS-compliant lead-free finish | Enables compliance with EU Directive 2011/65/EU without process change in lead-free reflow profiles. |

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), but higher VFM (1.3 V) | Better suited for high-frequency PFC or snubberless flyback where reverse recovery matters | Select when reducing switching losses outweighs conduction loss penalty |
| Vishay VS-1N4007TR | Through-hole DO-41, 1 A I(AV), 1000 V VRRM, higher VFM (1.1 V @ 1 A), no RoHS lead-free option standard | Legacy replacement in repair or low-volume through-hole designs only | Use only if board redesign for SMT is not feasible; not recommended for new designs |
Compared with MUR160 and 1N4007TR, S2J-13 delivers optimal balance of low conduction loss, surface-mount manufacturability, and RoHS compliance for cost-sensitive 60 Hz rectification-without ultrafast timing overhead or legacy packaging constraints.

FAQ
What is the maximum allowable PCB copper pad area for thermal performance validation?
The datasheet specifies thermal resistance (RJT = 20 °C/W) measured using 5.0 mm² of 0.013 mm thick copper as heatsink. Increasing pad area beyond this improves thermal performance incrementally, but 5.0 mm² is the validated baseline for achieving full 1.5 A I(AV) rating at 100°C terminal temperature.
Can S2J-13 be used in full-wave bridge configurations?
No-S2J-13 is a single diode in SMA package. Full-wave rectification requires four such diodes arranged in a bridge topology. Diodes Incorporated offers dedicated bridge rectifiers (e.g., DB107S) for that purpose; S2J-13 is intended only for half-wave or single-diode applications.
Does the "-13" suffix indicate tape-and-reel packaging?
Yes-the "-13" suffix denotes 5000-piece tape-and-reel packaging per the ordering information on page 2 of DS16004. This format is optimized for automated pick-and-place assembly and matches standard SMT feeder specifications.
Is there a lead-free version of S2J-13, and how is it designated?
Yes-Diodes Incorporated offers a RoHS-compliant, lead-free version designated S2J-13-F, featuring matte tin plating. It shares identical electrical and thermal specifications and is qualified for the same reflow profiles as the standard part.
