Reverse leakage is 100 µA at 45 V rated reverse voltage — a typical Schottky trade-off: lower Vf comes with higher leakage at elevated junction temperature, so the leakage contribution to the thermal budget grows above 100°C. Housed in a TO-252-3 (DPAK) surface-mount package with two leads plus the tab — the tab is the cathode and the primary thermal path.","metaTitle":"STPS1045BY-TR Schottky Diode 45V 10A DPAK","metaDescription":"STPS1045BY-TR Schottky rectifier rated 45 V reverse, 10 A average, 630 mV Vf at 10 A.
