SK1840D2

Single Diodes Overview

The SK1840D2 is a single-element silicon Schottky rectifier diode manufactured by Diotec Semiconductor. It features a D2PAK-3 (TO-263AB) surface-mount package with the cathode connected to the exposed thermal pad for efficient heat dissipation. The device is rated for a maximum repetitive reverse voltage of 40 V and an average forward rectified current of 18 A. Key electrical characteristics include a low forward voltage drop of 580 mV at full load, a non-repetitive peak surge current capability of 320 A, and a maximum reverse leakage current of 200 µA. It operates within a junction temperature range of -50°C to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix 'D2' against the manufacturer's official datasheet to confirm the exact tape-and-reel or tube packaging configuration intended for your assembly process. Ensure that the ordering documentation explicitly references the complete part number SK1840D2 to distinguish it from other variants within the SK18 series. Cross-reference the RoHS compliance status with the latest environmental declaration provided by Diotec Semiconductor prior to final procurement.

Single Diodes Selection Notes

Select this component when designing circuits requiring high current handling up to 18 A with a 40 V blocking voltage rating. The D2PAK-3 package is suitable for applications demanding superior thermal performance compared to smaller surface-mount packages. Consider the low forward voltage characteristic for efficiency optimization in low-voltage DC systems where conduction losses are critical.

Single Diodes Part Context

This component belongs to the SK1/2/3/4/5/8/L series of Schottky diodes produced by Diotec Semiconductor. The series offers various current and voltage ratings across different package types. The SK1840D2 specifically addresses the need for medium-to-high current rectification in a compact surface-mount form factor, bridging the gap between lower-current SMB/SMA packages and larger through-hole options.
