It is built for medium-voltage, high-current rectification and freewheeling in switch-mode power supplies, DC-DC converters, and polarity protection circuits where low forward drop and fast switching are needed. Forward voltage is specified at 840 mV maximum at 30 A — roughly double the rated average current — which gives the designer a realistic conduction-loss ceiling under surge or start-up conditions. At the 15 A average rating the actual Vf will be lower, but the 30 A figure is the one to use for worst-case thermal budgeting. Reverse leakage is 200 µA at 45 V. Leakage doubles with every 10 °C rise in junction temperature, so in a hot environment — say 125 °C ambient inside a sealed power supply — the standby loss can climb significantly. STMicroelectronics no longer manufactures this device, and no official last-time-buy window or successor order code is recorded in the available lifecycle data. Procurement for this part runs through the independent distribution channel — surplus inventory, factory overruns, and broker-sourced stock. Availability and pricing vary by lot and are confirmed only at quote time against the specific BOM quantity. There is no factory lead time to quote because the line is closed. For a new design or a production line that requires a guaranteed supply chain, a currently-manufactured Schottky in the same voltage and current class should be evaluated for pin-compatibility and electrical fit. ## Package and thermal — D2PAK footprint notes The D2PAK (TO-263-3) package has a large exposed copper tab on the bottom — the cathode connection. Reflow profile follows standard lead-free soldering; the tab solder joint is the critical one for both electrical and thermal performance.","metaTitle":"STPS1545G-TR Schottky Diode, 45 V, 15 A, D2PAK – Obsolete","metaDescription":"STPS1545G-TR Schottky rectifier: 45 V reverse, 15 A average, 840 mV forward drop at 30 A.
