SK34 is an electronic part manufactured by DIYI that features Schottky Barrier Diodes (SBD). It has a DO-214AA form factor and is RoHS compliant. The SBD SMB package contains two opposing SBDs in a single package. The SBDs are useful in suppressing electromagnetic interference (EMI) and providing fast switching. They are also helpful in preventing inductive voltage spikes, especially for applications with higher currents. SBDs are typically used in diode bridge, high-speed switching, electrical isolation, signal line protection, and as a full-wave rectifier.
