Its 30 ns reverse recovery time (trr) places it in the ultrafast class, well inside the Fast Recovery =< 500ns, > 200mA (Io) category — the 30 ns figure is the one that matters for a 70–150 kHz switching edge. ## 1.5 A continuous and 200 V blocking — where it fits the BOM A 1.5 A average rectified current (Io) with a 1 V forward drop at that current gives a 1.5 W conduction loss floor before any thermal derating. The 200 V reverse voltage (Vr) provides margin on 48 V and 100 V DC rails, but falls short for 230 VAC offline rectification (which peaks at ~325 V). The 3 µA reverse leakage at 200 V is tight enough to keep standby losses negligible in a bias supply. ## SMB footprint and 175 °C junction rating The SMB body is larger than the SMA sibling, which helps spread heat in a board with limited copper area. ## Active lifecycle and compliance status It is ROHS3 compliant, which clears it for EU and RoHS-restricted markets without an exemption review.","metaTitle":"STTH1R02U Fast Recovery Diode, 200V 1.5A SMB, 30ns trr","metaDescription":"STTH1R02U from STMicroelectronics: 200V 1.5A fast recovery rectifier, 30ns trr, DO-214AA SMB.
