Specification

Description

The 1N4148 is a popular small-signal switching diode, not a Zener diode. It's often used in applications where fast switching times and high switching speeds are required.

Here's a description of its features:

Type: The 1N4148 is a general-purpose small-signal diode.

Power Dissipation: It can handle up to 500 milliwatts (0.5 watts) of power dissipation under normal operating conditions.

Voltage Rating: While it is not a Zener diode, the 1N4148 has a maximum repetitive reverse voltage (VRRM) of 100 volts. This means it can withstand up to 100V in reverse bias without breaking down.

Forward Voltage Drop: The forward voltage drop across the diode is typically around 0.7 volts when conducting current in the forward direction.

Fast Switching Speed: The 1N4148 is known for its fast switching times, making it suitable for applications where rapid switching between on and off states is required.

Package Type: It is available in various through-hole and surface-mount packages, making it versatile for different circuit designs.

Construction: The 1N4148 is constructed using silicon semiconductor material and is typically housed in a small glass or plastic package with two leads (anode and cathode).

Applications:

Common applications for the 1N4148 include signal rectification, small-signal switching, voltage clamping, and protection circuits in electronic devices such as amplifiers, oscillators, and digital circuits.
