SK2545YD2-3G

Single Diodes Overview

The SK2545YD2-3G is a surface-mount Schottky barrier rectifier diode manufactured by Diotec Semiconductor. It features a TO-263AB (D²PAK) package and is rated for a repetitive peak reverse voltage of 45 V and a maximum average forward rectified current of 25 A at a case temperature of 125°C. The device exhibits a low forward voltage, typically 0.44 V at 10 A and 25°C, with a maximum rating of less than 0.56 V at 25 A. Peak forward surge currents are specified as 290 A for a 50 Hz half-sine wave and 330 A for a 60 Hz waveform. The junction-to-case thermal resistance is 1.5 K/W, supporting operation within a junction temperature range of -50°C to +150°C.

Single Diodes Feature Summary

• Low forward voltage drop, particularly at lower forward currents
• Very low leakage current characteristics
• Low thermal resistance between junction and case
• Compliant with RoHS directives and REACH regulations

Single Diodes Applications

Single Diodes Procurement Notes

Verify the specific ordering suffix when procuring this component. The standard version lacks automotive qualification, whereas suffixes such as -Q indicate AEC-Q101 compliance and -AQ indicates active qualification. Confirm that the required grade matches the application's reliability standards before finalizing orders.

Single Diodes Selection Notes

Select this component for applications requiring high current handling in a compact surface-mount form factor. Ensure the design accommodates the 25 A average current limit at elevated case temperatures. Verify that the 45 V reverse voltage rating provides adequate margin for the circuit's operating conditions and transient spikes.
