The 1.04 V forward drop at 2 A is typical for this voltage class — not the lowest Vf on the market, but the trr is the spec that matters for a hard-switched converter. ## Automotive-grade pedigree and junction temperature The ECOPACK2 label confirms the device is halogen-free and RoHS-compliant per ST's green-molding compound. The DO-214AC body is the same pad layout as the standard SMB/SMC diodes but with a lower profile — reflow profile per JEDEC MSL level 1 (no bake required if the bag seal is intact). The cathode band is marked on the body; verify orientation before pick-and-place because a reversed diode in an automotive ECU means a failed board-level test.","metaTitle":"STTH2R02AY 2A 200V Fast Recovery Diode, SMA, AEC-Q101","metaDescription":"STTH2R02AY 2A 200V fast recovery diode in SMA package. 30 ns trr, AEC-Q101 automotive qualified.
