LL4148-7 Description

Short technical summary and product information.

The LL4148-7 is a fast switching surface mount diode manufactured by Diodes Incorporated. It utilizes silicon epitaxial planar construction for high-speed switching applications. The diode has a maximum DC blocking voltage of 75V and an average rectified output current of 150mA. Forward voltage is 1V at 10mA, and reverse recovery time is 4ns, making it suitable for high-speed circuits.

 

The device is packaged in a Mini MELF (DO-213AC) surface mount package, ideal for automated assembly. It can handle a non-repetitive peak forward surge current of 1.0A for 1 second. Power dissipation is 500mW, and operating temperature range is -65°C to 175°C. The diode features a lead-free finish and is RoHS3 compliant, with MSL Level 1 moisture sensitivity.

 

Typical applications include general purpose rectification, switching power supplies, and signal demodulation. The Mini MELF package offers a compact design with low thermal resistance (300 K/W junction-to-ambient).
