AEC-Q101 qualification is the automotive industry's stress-test qualification for discrete semiconductors. For a procurement decision, that qualification is the difference between a part that can be specified into an ECU BOM without a separate qualification run and one that requires the OEM's PPAP approval cycle. The Automotive grade tag and the -GY suffix in the order code both signal this qualification level. The base product number STPS2045 also appears in non-automotive variants; verify the full code before committing the line. ## 10 A per diode, 570 mV Vf — the thermal budget At 10 A per diode, each junction dissipates roughly 5.7 W at full load. In the D2PAK package, that heat has to move through the exposed tab into the PCB copper. The 100 µA reverse leakage at 45 V is typical for a 45 V Schottky at elevated temperature; expect it to rise with junction temperature, which matters for standby-power budgets in always-on automotive modules. ## Sourcing and storage Store the reels in a dry cabinet — the D2PAK package is MSL-rated, and moisture exposure before reflow can cause package cracking at the soldering temperatures used for automotive-grade assemblies.","metaTitle":"STPS2045CGY-TR Schottky Diode, 45V 10A Dual Common Cathode","metaDescription":"STPS2045CGY-TR automotive Schottky rectifier: 45V Vr, 10A per diode, 570mV Vf, 175°C junction.
