FDLL4148 Description

Short technical summary and product information.

The FDLL4148 is a small signal switching diode from On Semiconductor, part of the industry-standard 1N4148 family. Housed in a surface mount SOD-80 (DO-213AC) package, it is designed for high-speed switching applications requiring low capacitance and fast recovery.

 

Key electrical specifications include a maximum repetitive reverse voltage (VRRM) of 100V, an average rectified forward current (Io) of 200mA, and a forward voltage drop of 1V maximum at 10mA. The reverse recovery time (trr) is a fast 4ns maximum, and the typical junction capacitance is 4pF at 0V and 1MHz.

 

Thermally, the FDLL4148 can dissipate up to 500mW and operate over a junction temperature range of -55°C to +175°C. It is supplied in tape and reel packaging, suitable for automated assembly.
