That 170 V reverse rating puts it into the 48–72 V bus converter space and PFC boost stages where a standard 100 V Schottky would leave no headroom for transients. The 8 A average forward current is continuous-rated, not surge — the die is sized for steady-state conduction in a 175°C junction environment. At 8 A the forward voltage is 900 mV max — higher than a low-Vf 100 V Schottky, but that is the price of 170 V blocking. The reverse leakage at rated voltage is 15 µA, which at 175°C junction climbs significantly (the datasheet curve shows the typical rise). ## Package and mounting — PowerFlat 3.3x3.3 The 8-PowerTDFN package (ST calls it PowerFlat 3.3x3.3) is a leadless surface-mount with an exposed die pad on the bottom. The pad carries the cathode current and is the primary thermal path — the PCB land pattern must match the recommended footprint in the datasheet, with thermal vias to an inner-layer copper pour. ROHS3 compliant. No official second-source or cross-reference is listed; the part is sole-sourced to ST.","metaTitle":"STPS8170DEE-TR Schottky Diode, 170V 8A, PowerFlat 3.3x3.3","metaDescription":"STPS8170DEE-TR Schottky rectifier: 170V reverse, 8A forward, 900mV Vf at 8A, 175°C Tj max, PowerFlat 3.3x3.3 surface-mount.
