It is a standard-recovery Schottky (not ultrafast) with a forward drop of 840 mV at 15 A — twice the average rating, which gives a realistic conduction loss figure for surge or inrush conditions. ## Junction temperature and thermal headroom Rated for a maximum junction temperature of 175°C, this diode can operate in confined or high-ambient enclosures — think sealed power supplies, motor drives, or industrial converters — without derating the current prematurely. The TO-220AC tab is the primary heat path; a heatsink or chassis mount is expected at 7.5 A continuous.","metaTitle":"STPS745D Schottky Diode, 45V 7.5A, TO-220AC, Active","metaDescription":"STPS745D Schottky diode, 45 V reverse, 7.5 A average, 840 mV Vf at 15 A, 175°C Tj max.
