Product details
Overview
S2K-13 from Diodes Incorporated is a glass passivated surface-mount silicon rectifier diode in SMB package, rated for 800 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 primary AC/DC input rectifier in offline power supplies and DC link protection circuits.
For engineers reviewing the S2K-13 datasheet, S2K-13 pinout, S2K-13 application, or S2K-13 equivalent, key selection criteria include its 1.15 V forward voltage at 1.5 A, 5.0 µA reverse leakage at 25°C, 20 pF junction capacitance, 20 °C/W thermal resistance (junction-to-terminal), and compatibility with automated SMT assembly on PCBs with 5.0 mm² copper pads.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz AC line 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 SMB-packaged S2K-13 exhibits a typical thermal resistance of 20 °C/W when mounted on specified PCB copper pads, enabling reliable conduction at full 1.5 A average current only when terminal temperature is maintained ≤100°C per the derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse voltage the diode blocks without breakdown in repetitive operation. |
| I(AV) | 1.5 A at TT = 100°C - Continuous DC output current capability with proper PCB heatsinking. |
| IFSM | 50 A (8.3 ms half-sine) - Surge withstand for cold-start inrush or transient overloads. |
| VFM | 1.15 V @ IF = 1.5 A - Forward conduction loss directly impacting efficiency and thermal design. |
| IRM | 5.0 µA @ 25°C, rated VR - Reverse leakage determining standby power and high-impedance circuit integrity. |
| RJT | 20 °C/W - Thermal path resistance from junction to PCB pad, critical for thermal management layout. |
| CT | 20 pF @ 1 MHz, 4 V - Junction capacitance affecting high-frequency switching noise and EMI filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | Ultrafast recovery (75 ns), lower VFM (1.0 V), same 800 V VRRM and 1.5 A I(AV). | Better suited for higher-frequency switching topologies requiring reduced reverse recovery loss. | Select when operating above 20 kHz or minimizing EMI from reverse recovery spikes. |
| Vishay VS-1N5408 | Through-hole DO-201AD package, 1000 V VRRM, 3 A I(AV), higher VFM (1.2 V). | Designed for legacy through-hole manufacturing and higher current margin at cost of board space. | Select for manual assembly, prototyping, or designs requiring >1.5 A headroom with no SMT constraints. |
Compared with MUR160 and VS-1N5408, S2K-13 offers optimal balance of SMT compatibility, 800 V rating, and thermal performance on PCBs-making it preferred for space-constrained, automated production of mid-power offline converters.

FAQ
What is the maximum allowable PCB copper pad area for thermal performance validation?
The datasheet specifies thermal resistance (RJT = 20 °C/W) is measured using 5.0 mm² of 0.013 mm thick copper pad per terminal. Using smaller pads increases thermal resistance nonlinearly; pad dimensions must match this reference for guaranteed 1.5 A I(AV) rating at 100°C terminal temperature.
Can S2K-13 be used in full-wave bridge configurations?
Yes-S2K-13 is a single diode intended for use in discrete full-wave bridge assemblies. Four units can form a standard bridge rectifier; ensure matching VFM and thermal layout symmetry across all four devices to prevent current imbalance and localized overheating.
Is the -13 suffix indicative of tape-and-reel packaging?
Yes-the "-13" suffix denotes SMB-packaged S2K devices supplied in 3000-unit tape-and-reel format per JEDEC standard, compatible with automated pick-and-place equipment. The alternate SMA version uses "-13" with "AA" prefix (e.g., S2KA-13).
Does S2K-13 meet automotive AEC-Q101 requirements?
No-S2K-13 is not AEC-Q101 qualified. It is rated for industrial and commercial temperature ranges (–65°C to +150°C), but lacks the stress testing, failure analysis, and traceability documentation required for automotive under-hood applications.
