LL4148 Description

Short technical summary and product information.

The LL4148 is a standard switching diode manufactured by Diotec Semiconductor. It is designed for general-purpose switching applications requiring fast recovery times. With a reverse voltage rating of 100V and a forward current of 150mA, it is suitable for low-power signal switching. The diode exhibits a typical forward voltage of 1V at 10mA forward current and a reverse recovery time of 4ns, enabling efficient switching in high-speed circuits. The junction capacitance is 4pF at 0V bias and 1MHz, offering minimal signal distortion. Packaged in a surface mount SOD-80 (also known as DO-213AC or MINI-MELF), the LL4148 is compatible with automated assembly processes. It operates over a temperature range of -50°C to 175°C, providing reliable performance in demanding environments. This diode is commonly used in rectification, clamping, and protection circuits where small size and fast switching are required.
