12 A Schottky in a TO-277A footprint
The STPS1230SF is a 30 V, 12 A Schottky rectifier from STMicroelectronics in the ECOPACK®2 series, housed in a TO-277A (SMPC) surface-mount package. With a fast recovery speed under 500 ns, it handles the reverse-recovery losses in a switched-mode power supply or a DC-DC converter output stage without forcing a slower diode's thermal penalty.
Reverse leakage and junction temperature
Reverse leakage is 360 µA at the rated 30 V blocking voltage. At 150°C maximum junction temperature, the leakage current rises exponentially — the thermal design must budget this self-heating, especially in a compact TO-277A pad where the copper area under the cathode tab sets the thermal resistance to ambient.
Active lifecycle and compliance
ROHS3 compliant, which covers the full RoHS exemption scope including lead-free soldering profiles. The ECOPACK®2 designation confirms the package is halogen-free per ST's internal specification.
