SMAF Package Ultrafast Recovery Diodes for High-Frequency Rectification and Fast-Switching Power Applications, 50V–800V, Up to 3A
The SMAF (Surface Mount Flat) package ultrafast recovery diodes feature compact profiles, low thermal resistance, and fast reverse recovery time as low as 25ns. Designed for surface-mount high-frequency applications, the series supports average forward currents from 1A to 3A and reverse voltage ratings from 50V up to 800V. Key advantages include minimized switching loss, reduced EMI, and reliable thermal stability across -55°C to +150°C.
