SMF05-B is a 4-channel unidirectional ESD protection diode array manufactured by Slkor, encapsulated in tiny SOT-353 surface-mount plastic package. It is designed to protect voltage-sensitive ICs and high-speed interfaces from damage caused by ESD and electrical transient surges. Featuring excellent clamping performance, ultra-low leakage current, low junction capacitance and nanosecond-level fast response speed, this component can replace multi-layer varistors (MLV) in mainstream consumer electronics. It delivers reliable ESD suppression for HDMI, DisplayPort, MDDI and other high-speed signal ports, and fits compact portable devices such as mobile phones, notebooks, tablets and set-top boxes.
