MMSD4148 – FSC

The MMSD4148, manufactured by Fairchild Semiconductor (FSC), is a silicon epitaxial planar switching diode encapsulated in a SOD-123 surface-mount package. This diode features a maximum repetitive peak reverse voltage (VRRM) of 100V and a continuous forward current (IF) rating of 200mA. Its forward voltage (VF) is typically 0.8V at IF = 10mA, with a maximum of 1.0V at IF = 100mA. The reverse recovery time (trr) is specified as a maximum of 4 ns, making it suitable for high-speed switching applications. The junction capacitance (CJ) is typically 4 pF at VR = 0V and f = 1MHz. The MMSD4148 is designed for general-purpose switching and signal applications where low capacitance and fast switching speeds are required.
