Its 4 ns reverse recovery time makes it a solid choice for high-frequency rectification, snubbing, and general-purpose switching up to the Vr and Io limits. The SOT-323 footprint is small enough for dense layouts but still hand-solderable for rework.
4 ns trr — where it earns its keep
The 1.25 V forward drop at 150 mA is typical for a 250 mA-rated silicon diode.
It is a current-production Infineon part, available through independent distribution. No imminent obsolescence risk for new designs.
