MMSD4148 Description

Short technical summary and product information.

The MMSD4148 is a standard switching diode from ON Semiconductor designed for high-speed switching applications. It is housed in a compact SOD-123 surface mount package, making it suitable for automated assembly and space-constrained designs.

 

Key electrical specifications include a maximum continuous reverse voltage of 100V, forward current of 200mA, and a forward surge current capability of 1A for less than 1 second. The diode exhibits a fast reverse recovery time of 4ns at 10mA, enabling efficient switching in high-frequency circuits. Forward voltage is typically 1V at 10mA, and diode capacitance is 4pF at 0V.

 

The device operates over a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 425mW on an FR-5 board. It is Pb-Free, Halogen Free, and RoHS compliant, with automotive-grade variants (SMMSD4148) available.
