It carries a typical forward voltage of 450 mV at 2 A, which keeps conduction losses down in 5 V and 3.3 V rail rectification or freewheeling paths. ## 450 mV forward drop — the efficiency lever At 2 A forward current the Vf max is 450 mV — about 0.9 W dissipation at full load. That low drop matters most in low-output-voltage converters where every 100 mV of diode loss cuts efficiency by a couple of points. Reverse leakage is 200 µA at 30 V, typical for a 30 V Schottky at this current rating. ## DO-221AC SMA Flat Leads — hand-solderable SMD The SMA Flat Leads package (DO-221AC) is a surface-mount body with flat, exposed leads that sit flush on the pad. That geometry makes it easier to hand-solder than a standard SMA gull-wing — good for rework or small-batch assembly. The junction temperature ceiling is 150 °C, so keep the copper pad area generous under the cathode tab to pull heat away. STMicroelectronics lists the STPS2L30AFN as Obsolete.","metaTitle":"STPS2L30AFN Schottky Diode, 30V 2A, DO-221AC SMA Flat Leads","metaDescription":"STPS2L30AFN Schottky diode, 30V reverse, 2A average, 450mV Vf at 2A.
