Description:

The 1N4148 High Speed Fast Switching Diode – Pack of 50 is a general-purpose silicon switching diode known for its rapid response and reliability. With a reverse recovery time of just 4 nanoseconds, it is ideal for high-speed signal processing, logic circuits, waveform shaping, and protection applications. Frequently used in microcontroller inputs, signal lines, and small-signal switching systems, the 1N4148 offers excellent performance in both analogue and digital designs.

This diode can handle up to 300 mA of continuous forward current with a peak repetitive reverse voltage of 100V. Its small signal capability and high switching speed make it suitable for timing, clipping, and high-frequency applications. Encased in a DO-35 glass axial package, these diodes are compact and easy to solder on PCBs or insert into breadboards. With 50 units in each pack, it’s a cost-effective solution for rapid prototyping, repair work, or manufacturing runs.
