It is designed for high-current power rectification, OR-ing, and freewheeling applications where low forward voltage and fast switching are needed. Reverse leakage is specified at 10 µA at 100 V. ## Forward drop and thermal budget at 20 A In a 40 A total output (both diodes conducting), the combined forward power dissipation is roughly 32 W at full load, which the TO-220 package must shed through a heatsink. Reverse leakage at 10 µA at 100 V is typical for a 100 V Schottky at room temperature, but expect leakage to rise exponentially with junction temperature — a factor to budget in high-ambient or minimally cooled enclosures. ## Active production, no obsolescence watch No last-time-buy or substitution pressure applies.","metaTitle":"STPS41H100CT Schottky rectifier, 20 A per diode, 100 V","metaDescription":"STMicroelectronics STPS41H100CT dual Schottky rectifier, 20 A average per diode, 100 V reverse, 800 mV Vf at 20 A.
