Product details
Overview
SK16-13 from Diodes Incorporated is a surface-mount Schottky barrier rectifier with 60 V maximum recurrent peak reverse voltage, 1.0 A average forward rectified current at 75°C, and 0.70 V typical forward voltage at 1.0 A. It features low thermal resistance (25 °C/W), 110 pF junction capacitance at 1 MHz, and operates from –65 °C to +125 °C - used in DC-DC converter output stages and low-voltage AC/DC adapters.
For engineers reviewing the SK16-13 datasheet, SK16-13 pinout, SK16-13 application, or SK16-13 equivalent, key selection factors include its 60 V blocking rating, SMB package thermal performance, Schottky low VF advantage over PN diodes, and compatibility with high-frequency switching topologies requiring fast recovery and minimal conduction loss.
Technical Context
This Schottky rectifier employs a metallurgically bonded silicon junction optimized for low forward voltage drop and fast switching response. Its 60 V VRRM rating supports 48 V system inputs and PoE-powered devices, while the 25 °C/W junction-to-lead thermal resistance enables reliable operation on 6 mm² copper pads without forced airflow.
The device exhibits 10 mA maximum DC reverse current at 100 °C and rated blocking voltage, confirming stable leakage behavior under elevated ambient conditions. Its 110 pF capacitance at 1 MHz and 4 V reverse bias makes it suitable for <1 MHz SMPS outputs where capacitive loading must remain predictable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - supports 48 V nominal input rails with 25% margin for transients |
| I(AV) | 1.0 A at TA = 75 °C - usable in compact 5–12 V DC-DC outputs with 6 mm² copper pad layout |
| VF | 0.70 V at 1.0 A - reduces conduction loss by ~35% vs. comparable PN rectifiers |
| IFSM | 25 A (8.3 ms half-sine) - withstands inrush surges in offline adapter primary-side snubbers |
| RθJL | 25 °C/W - enables 1.0 A continuous operation with ≤25 °C temperature rise above lead |
| CT | 110 pF at 1 MHz / 4 V - limits high-frequency displacement current in flyback secondary networks |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case, UL 94V-0 rated, moisture sensitivity level 1. Cathode indicated by band or notch. Terminals are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to transformer secondary or switch node; requires low-inductance trace routing |
| Cathode | Current exit point during forward conduction | Connected to output capacitor and load; polarity marked by band; critical for EMI filter grounding |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF = 0.70 V @ 1.0 A - directly lowers power loss and improves efficiency in 5–12 V output stages |
| High surge capability | IFSM = 25 A - sustains repeated cold-start events in industrial power supplies without degradation |
| Thermal robustness | RθJL = 25 °C/W - allows full-rated current on standard PCB land patterns without heatsinking |
| RoHS-compliant plating | Matte tin finish available (-F suffix) - meets lead-free assembly requirements for IPC-J-STD-020C Level 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| B160B-13-F | Same SMB package, 60 V VRRM, but lower I(AV) = 1.0 A at 100 °C (vs. 75 °C for SK16-13); VF = 0.55 V @ 1.0 A | Better efficiency at high ambient; slightly reduced surge rating (IFSM = 20 A) | Preferred for thermally constrained designs above 75 °C ambient |
| SS16-E3/5AT | Vishay SMB Schottky; 60 V VRRM, I(AV) = 1.0 A @ 75 °C, VF = 0.75 V @ 1.0 A, RθJL = 30 °C/W | Higher thermal resistance limits power density; tighter IR distribution at 100 °C (max 5 mA) | Suitable when supply chain diversification is required and 5 °C/W higher thermal penalty is acceptable |
Compared with SK16-13, B160B-13-F offers lower forward voltage but reduced surge tolerance, while SS16-E3/5AT trades 5 °C/W higher thermal resistance for broader distributor availability - both require revalidation of thermal layout and surge margin in existing designs.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design centers across Asia and manufacturing in China, Taiwan, and the U.S.
The SK-series Schottky rectifiers target cost-sensitive, high-volume power conversion applications where low VF, SMB footprint, and JEDEC-compliant surge robustness are prioritized over ultra-low leakage or extended temperature grades.
FAQ
Is SK16-13 RoHS compliant?
Yes, SK16-13 is RoHS compliant per EU Directive 2011/65/EU, with exemptions applied for glass and high-temperature solder per Annexes 5 and 7. A lead-free matte tin finish version is available as SK16-13-F, qualified to J-STD-020C Level 1 moisture sensitivity.
What is the maximum operating junction temperature for SK16-13?
The maximum junction temperature is +125 °C, with storage temperature extending to +150 °C. Derating begins at 75 °C ambient for full 1.0 A average current; Fig. 1 in DS13003 Rev. 8 shows linear derating to zero at 160 °C ambient on 6 mm² copper pads.
Can SK16-13 replace SK15-13 in an existing design?
Yes - both share identical SMB package, pinout, and thermal characteristics. SK16-13 offers 60 V VRRM versus SK15-13's 50 V, providing 20% higher blocking margin. No layout or thermal changes are needed, though reverse leakage may increase slightly at high temperature due to higher VRRM process trade-off.
Does SK16-13 have a specified reverse recovery time (trr)?
No - as a Schottky barrier rectifier, SK16-13 has no minority-carrier storage and therefore no defined reverse recovery time. Its switching is limited only by junction capacitance (110 pF) and circuit inductance, making it inherently faster than PN diodes in high-frequency applications.
