The forward voltage is specified at 760 mV at 3 A, and it carries a fast recovery time of ≤500 ns above 200 mA. This part is part of the ECOPACK2 series, indicating RoHS compliance and halogen-free construction. Typical applications include high-frequency DC-DC converters, freewheeling diodes, and polarity protection in power supplies that operate in elevated temperature environments such as industrial or automotive under-hood locations. ## Obsolete status and sourcing reality The STPS3H100UFN is listed as obsolete. This means STMicroelectronics has discontinued production, and no last-time-buy window is indicated in the available records. The 100 V reverse voltage and 3 A forward current define the primary selection envelope. The 760 mV forward drop at 3 A is typical for a 100 V Schottky at this current level — it affects thermal dissipation in the PCB layout, particularly in continuous-conduction designs. The fast recovery spec (≤500 ns above 200 mA) confirms this is a switching diode, not a slow-recovery rectifier, so it is suited for switching frequencies in the tens to low hundreds of kHz.","metaTitle":"STPS3H100UFN Schottky Diode, 100 V 3 A, SMA Flat Leads","metaDescription":"STPS3H100UFN Schottky rectifier, 100 V reverse, 3 A average, 760 mV Vf at 3 A.
