STMicroelectronics lists the STPS1545CG as obsolete. Sourcing this part today means going through the independent surplus and broker channel, where availability depends on what is left in inventory from past production runs. The 45 V reverse voltage rating sets the maximum DC bus voltage this diode can block — suitable for 24 V and 36 V rails with margin, but not for 48 V telecom supplies. Reverse leakage is specified at 100 µA at 45 V, which matters for standby power budgets in battery-powered or always-on equipment. The D2PAK (TO-263-3) package has two leads plus the tab, which is the cathode common terminal. The exposed metal tab must be soldered to the PCB copper pour for thermal management — without a good thermal connection, the junction temperature rises quickly above the 175°C limit under sustained load. The part ships in Tube form, not tape-and-reel, so plan for manual or tube-fed placement if you are setting up a production line.","metaTitle":"STPS1545CG Schottky Diode, 45V 7.5A Dual Common Cathode","metaDescription":"STPS1545CG dual Schottky rectifier: 45V Vr, 7.5A per diode, 570mV Vf, 175°C Tj.

For a drop-in replacement, look for a dual common-cathode Schottky in D2PAK with a 45 V reverse voltage and at least 7.5 A per diode rating. Parts like the MBRB1545CT or similar from other manufacturers may fit, but verify the footprint and thermal pad layout against the D2PAK package before committing the BOM."},{"question":"What is STPS1545CG's listed speed?","answer":"The part is a Schottky diode, so it is inherently a fast-recovery device — the specification lists a recovery time of ≤ 500 ns at > 200 mA forward current. That is typical for Schottky rectifiers and sufficient for switch-mode power supply output rectification up to several hundred kilohertz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS1545CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS1545CG when reusing this data.
