It is a straightforward replacement for common 5 A Schottky diodes in low-voltage power supplies, freewheeling diodes in DC-DC converters, and OR-ing diodes in redundant power systems. The through-hole package makes it a field-serviceable part — you can swap it on site with a standard soldering iron and a pair of cutters, no hot-air station required. At 5 A forward current the typical forward voltage is 500 mV. The reverse leakage is 200 µA at the rated 40 V reverse voltage. For production BOMs this means no imminent supply risk from obsolescence. The base product number is STPS5, so if you need a higher current or voltage variant within the same family the pinout and package footprint are consistent across the series.","metaTitle":"STPS5L40 Schottky Diode, 40V 5A DO-201AD","metaDescription":"STPS5L40 Schottky rectifier: 40V reverse, 5A average, 500mV forward drop at 5A, DO-201AD axial package.
