Its key parametric is a forward voltage of 395 mV at the full 1 A rated current, which keeps conduction losses low in low-voltage rails. The fast recovery characteristic — ≤500 ns above 200 mA — makes it suitable for switching power supplies where reverse-recovery charge matters, unlike a standard Schottky that is already majority-carrier fast. This part targets secondary-side rectification in AC-DC converters, freewheeling diodes in DC-DC stages, and polarity protection in battery-powered equipment where every millivolt of drop counts. That means STMicroelectronics has stopped production, and no further factory orders are accepted. The 150°C junction temperature rating is standard for this class and does not limit replacement options. ## Package and mounting — SMA Flat Leads The DO-221AC SMA Flat Leads package is a low-profile surface-mount form factor. The leads are flat rather than formed into a J-bend or gull-wing, which reduces the package height above the board. This is a standard footprint for automated pick-and-place assembly.","metaTitle":"STPS1L30AFN Schottky Diode, 30V 1A Fast Recovery","metaDescription":"STPS1L30AFN Schottky rectifier, 30V 1A, 395 mV Vf, fast recovery <500ns.

The STPS1L30 family in the standard SMA (non-flat-lead) package is a parametric match but has a different footprint. For a pin-compatible drop-in, check the DO-221AC package from other manufacturers — the 30 V, 1 A Schottky in SMA Flat Leads is a common cross-reference target."},{"question":"Is STPS1L30AFN RoHS compliant?","answer":"The evidence does not carry a RoHS compliance statement for this part. Most ST Schottky diodes from this era are RoHS-compliant, but the specific status should be verified against the date code on the reel or the manufacturer's compliance document. If RoHS is a hard requirement for your BOM, request a compliance declaration at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS1L30AFN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS1L30AFN when reusing this data.
