This is the 25°C figure; Schottky leakage rises exponentially with junction temperature, so at 125°C junction the leakage current can be an order of magnitude higher. For a 45 V rail in a hot engine bay, the leakage contribution to the thermal budget should be checked against the diode's total power dissipation. ## Common-cathode topology — where it fits The 1 Pair Common Cathode arrangement is the standard choice for center-tapped full-wave rectifiers, OR-ing diodes in redundant automotive power supplies, and freewheeling clamp networks where the cathodes share a common output node. The two anodes are independent, so the part can also serve as two separate Schottky diodes if the circuit layout accommodates the shared cathode pin. For a production BOM line, this part can be committed without near-term obsolescence risk.","metaTitle":"STPS15L45CBY-TR Schottky Diode Array, 45V 7.5A, AEC-Q101","metaDescription":"STPS15L45CBY-TR automotive Schottky diode array, 45V reverse, 7.5A per diode, 520mV Vf, common cathode pair in DPAK.
