Product details

What this Schottky does in the circuit

The STPS2L25UF is a 2 A, 25 V Schottky rectifier from STMicroelectronics, housed in the low-profile SMBflat package. It is designed for low-voltage, high-frequency rectification in switch-mode power supplies, DC-DC converters, and freewheeling diodes. The fast recovery spec (≤500 ns, >200 mA) is explicitly called out, though Schottky diodes are majority-carrier devices with inherently fast switching — this rating confirms it is characterized for higher-frequency operation where reverse-recovery charge matters.

Package and mounting note

The SMBflat package is a surface-mount, flat-lead design that saves board height compared to a standard SMB. The leads are formed flush with the body, which helps with automatic optical inspection.

Frequently asked questions

Is STPS2L25UF obsolete?

Yes, STMicroelectronics lists the STPS2L25UF as obsolete. There is no official replacement part number from ST.

What package does STPS2L25UF come in?

It is supplied in the SMBflat package (DO-221AA), a surface-mount flat-lead design. The supplier device package is SMBflat.

What is the reverse leakage current of STPS2L25UF?

The reverse leakage at 25 V is 90 µA maximum. This is typical for a 2 A Schottky at rated voltage; expect higher leakage at elevated junction temperature.
