The 550 mV forward voltage at 30 A and fast switching speed (Fast Recovery =< 500 ns, > 200 mA Io) made it a standard choice for output rectification in switch-mode power supplies, flyback converters, and OR-ing diode applications in telecom rectifiers and industrial power systems. ## Key ratings and the decisions they drive The 40 V reverse voltage rating sets the maximum DC blocking voltage; in practice, derate by 20% for reliable operation in 24 V or 28 V rails. The 30 A per-diode average current is the thermal design anchor — junction temperature is limited to 150 °C max, so heatsink sizing must account for the 550 mV forward drop at full load, which produces about 16.5 W of dissipation per diode. The common-cathode configuration pairs two diodes in one package, saving board space and simplifying layout for center-tap secondary windings.","metaTitle":"STPS60L40CW Schottky Rectifier, 40V 30A Dual Common Cathode","metaDescription":"STPS60L40CW is an obsolete ST Schottky rectifier, 40V 30A per diode, 550mV Vf, TO-247-3.

A form-fit-function substitute would need to match the 40 V, 30 A per diode, common-cathode configuration in TO-247-3. Common alternatives from other manufacturers include the MBR6045WT or similar 45 V dual Schottky in the same package, but pinout and thermal performance must be verified against the original design."},{"question":"Where can I buy STPS60L40CW?","answer":"Submit an RFQ to confirm current availability and pricing — stock is quoted to order, not held on a shelf."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS60L40CW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS60L40CW when reusing this data.
