Housed in a TO-247-3 through-hole package (MAX247), it suits designs where thermal mass and board-level heat sinking are needed — common in switch-mode power supply output stages and OR-ing circuits. STMicroelectronics lists the STPS80L15CY as obsolete. ## Parametric profile for the BOM check Fast recovery characteristic — ≤500 ns at >200 mA — makes it suitable for switching frequencies in the tens of kHz range typical of offline power converters. Reverse leakage is 16 mA at 15 V, a figure that rises with junction temperature; the maximum junction temperature is 125 °C. The dual-diode configuration in a single TO-247-3 package reduces component count and PCB area for center-tap full-wave rectification or dual-output OR-ing. Each diode handles 40 A continuously; the package thermal pad must be considered for full-load dissipation.","metaTitle":"STPS80L15CY Schottky Diode, 40A, 15V, TO-247-3, Obsolete","metaDescription":"STPS80L15CY dual common-cathode Schottky rectifier: 40A per diode, 15V Vr, 420mV Vf at 40A.
