Schottky rectifier — 60 V, 2 A, SMAflat Notch
The STPS2L60AFN is a 60 V, 2 A Schottky rectifier from STMicroelectronics in the SMAflat Notch surface-mount package. It carries a forward voltage of 600 mV at the rated 2 A forward current and a reverse leakage of 100 µA at 60 V. The fast recovery spec (≤500 ns, >200 mA) confirms this is a switching-grade Schottky, not a standard 50/60 Hz rectifier — it handles the reverse-recovery demands of a DC-DC converter or OR-ing diode without the stored-charge tail of a PN-junction part.
Obsolete — plan a replacement now
STMicroelectronics lists the STPS2L60AFN as obsolete. That means no factory orders, no last-time-buy window — the only channel left is independent distribution. If you are stocking a spare-parts bin or supporting a legacy board, buy enough to cover the remaining service life in one pass. The SMAflat Notch footprint is shared with other 2 A Schottkys in the STPS2 family, so a pin-compatible drop-in is the cleanest path.
The 2 A average rectified current is the DC load limit; in a switching supply the RMS current through the diode will be higher, so check the thermal derating curve. The 600 mV forward drop at 2 A is typical for a 60 V Schottky of this die size — expect it to run warm at full load in a small SMAflat package without good board copper to sink heat.
