The SS34 is a 3A 40V Schottky Barrier Rectifier in the compact SMA (DO-214AC) surface-mount package. It is widely used in high-frequency DC-DC converters, polarity protection circuits, and freewheeling diode applications where low forward voltage drop and fast switching are required.
YINT Electronics offers the SS34 Schottky diode with a maximum forward voltage of only 0.55V at 3A, significantly reducing power loss in low-voltage circuits. The device delivers a peak forward surge current (IFSM) of 100A, providing excellent robustness during startup and transient events.
With an operating junction temperature range of -65°C to +125°C and SMA tape-and-reel packaging (5000 pcs/reel), the SS34 is suitable for automated high-volume assembly. It is a drop-in replacement for industry-standard SS34 diodes from other manufacturers.
