Its key parametric for a design engineer is the forward voltage: 450 mV maximum at 2 A. The 30 V reverse rating covers most low-voltage DC rails with headroom for transients. Reverse leakage is 200 µA at 30 V, a figure to note if the circuit idles in standby with the diode reverse-biased. ## DO-214AC (SMA) — the footprint you already know The SMA footprint is a standard across many Schottky and rectifier diodes — if your board already has a land pattern for an SMA device, this part drops in without a layout change. Mounting is surface mount only. ## Where it is in the cycle — shortage desk view For a shortage-desk buyer, the STPS2L30AF sits in the post-production tail. It is obsolete, so the only stock in the channel is what was built before the EOL date. There is no allocation from ST — the part is simply not being made. The spot market carries what it carries; when that dries up, the only option is a substitute. If you are holding a BOM that still calls this out, now is the time to qualify an alternative or lock in whatever surplus is left. We can source it against an RFQ, but the window is closing.","metaTitle":"STPS2L30AF Schottky Diode, 2 A, 30 V, SMA Package, Obsolete","metaDescription":"STPS2L30AF is a 2 A, 30 V Schottky rectifier in DO-214AC (SMA) package.

A design engineer evaluating a replacement should look for a Schottky diode in the DO-214AC (SMA) package with a 2 A average current rating, 30 V reverse voltage, and a forward voltage at or below 450 mV at 2 A. Several ST Schottky parts in the same package family may fit, but pin-compatibility and parametric match must be verified against the original datasheet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS2L30AF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS2L30AF when reusing this data.
