Reverse leakage is specified at 125 µA at the 45 V reverse voltage rating. Leakage rises sharply with temperature; at sustained high junction temperatures the leakage contribution to self-heating needs to be factored into the thermal derating. ## Dual common-cathode in a single D2PAK The two Schottky diodes share a common cathode connection (pin 2 and the exposed tab), with the anodes on pins 1 and 3. This configuration is a direct fit for center-tapped secondary rectification, OR-ing diodes in redundant power feeds, or as a freewheeling pair in a half-bridge leg — all in one surface-mount package instead of two discrete parts.","metaTitle":"STPS2545CG Schottky Diode, 45V 12.5A Dual Common Cathode","metaDescription":"STPS2545CG Schottky rectifier, 45V 12.5A per diode, 570mV Vf, 125µA leakage.
