Junction temperature is rated to 175°C, suiting it for thermally demanding environments like industrial power converters, welding equipment, and high-current OR-ing diode applications. ## Obsolete — sourcing this part now STMicroelectronics lists the STPS30170CFP as obsolete. Sourcing is limited to the independent market — excess inventory, surplus lots, and broker stock. Every unit we quote is screened for marking consistency, date-code traceability, and physical authenticity before it ships. The laser etch on the TO-220FP body is a fingerprint we check against known ST production runs. ## Key ratings for the BOM decision The 170 V reverse voltage rating puts this in the high-voltage Schottky class — not a 40 V or 60 V low-voltage OR-ing diode. The 15 A per diode average current, combined with the 920 mV forward drop at that current, tells you the conduction loss at full load: roughly 13.8 W per diode, which the TO-220FP full-pack must sink through the case. The 20 µA leakage at 170 V is a room-temperature spec; expect leakage to multiply with junction temperature, so the 175°C max junction rating is a hard ceiling for thermal design. The common-cathode pair is useful for full-wave center-tap rectifiers or as a single high-current rectifier with the two diodes paralleled.","metaTitle":"STPS30170CFP Schottky Rectifier","metaDescription":"STPS30170CFP dual Schottky rectifier: 170V Vr, 15A per diode, 920mV Vf, TO-220FP full-pack.
