It targets PFC boost stages, flyback snubbers, and secondary-side freewheeling in offline power supplies where the bus voltage exceeds 400 V. ## 175°C junction — thermal headroom for sealed supplies Rated for a maximum junction temperature of 175°C, the STTH108A can deliver its full 1 A forward current in a high-ambient environment inside a sealed power supply enclosure where the board temperature reaches 85-100°C. A 150°C-rated diode would need derating or a larger package at those ambients.","metaTitle":"STTH108A 800V 1A Fast Recovery Diode, SMA, 75ns trr","metaDescription":"STTH108A: 800V 1A standard fast recovery diode in DO-214AC (SMA). 75ns trr, 1.65V Vf, 175°C Tj.
