Diotec‘s 3rd Generation Schottky Diode SK54-3G Offers Energy Savings and Temperature Reduction in LED Lightings

PublishTime： 2022-11-23 Article Source：Diotec News

Schottky Diode SK54-3G is using DIOTEC's 3rd Generation (-3G) Schottky chip technology. It comes in DO-214AA/SMB package and offers 5A/40V of nominal current and voltage rating. As such its ideally suited for the output rectifier stage of LED lamp drivers. Those devices are often built into suspended ceilings where heat removal is limited. This requires components with low power losses but also very good heat dissipation.

The SK54-3G offers a very low V_F of 250mV at 1A, and a low I_R of 500µA at 3V, both at 125℃ junction temperature and specified for typical operating parameters of Power LEDs. The low forward voltage and reverse current help to reduce power losses and thus save energy. The SMB package provides a very low thermal resistance junction to the terminal of 25K/W, which allows operation even at higher ambient temperatures.
