Its fast recovery speed (≤500 ns) makes it suitable for high-frequency switching in power supplies, DC-DC converters, and freewheeling diodes where reverse-recovery losses matter. ## Obsolete — plan your BOM transition STPS2170AFN carries an Obsolete lifecycle status. For new designs or production continuity, identify a pin-compatible replacement from ST's current Schottky portfolio. The base product number STPS2170 suggests a family of 2 A, 170 V devices; check the STPS2170 series for active variants in the same SMAflat Notch package. ## Package and assembly fit Housed in a DO-221AC SMA Flat Leads package (SMAflat Notch), this is a surface-mount device suited for automated pick-and-place.","metaTitle":"STPS2170AFN Schottky Rectifier, 170V 2A, SMAflat Notch","metaDescription":"STPS2170AFN Schottky rectifier: 170 V reverse, 2 A average, 820 mV forward drop, fast recovery ≤500 ns.
