RS1M SMD Diode SMAFn 46 MIL

RS1M SMD Fast Recovery Diode — SMA DO-214AC | 1A 1000V

The RS1M is a high-performance Surface Mount Fast Recovery Rectifier Diode housed in the compact SMA (DO-214AC) package. Rated at 1A forward current and 1000V peak reverse voltage, it is engineered for demanding high-frequency rectification tasks in modern electronics.

With a reverse recovery time of 500ns and a glass-passivated chip junction, the RS1M dramatically reduces switching losses in high-speed circuits — making it the go-to component for SMPS (switched-mode power supplies), flyback converters, freewheeling diode circuits, and pulse rectification applications.

Unlike general-purpose diodes like the 1N4007 (max 1KHz), the RS1M operates up to 1MHz, giving design engineers a critical performance edge in compact, miniaturized PCB designs where space and efficiency both matter.
