The 1N4148 Zener Diode is a high-speed switching and protection diode widely used in electronic circuits for voltage regulation, clamping, and protection applications. With a maximum reverse voltage of 100V and a current handling capacity of 200mA (0.2A), it is ideal for low-power and precision electronics.
This diode is well-known for its fast switching speed (nanoseconds range), making it suitable for high-frequency applications such as signal processing, waveform shaping, and digital logic circuits. The 1N4148 provides reliable over-voltage protection by limiting the voltage across sensitive components, ensuring circuit stability and safety.
Its compact DO-35 glass package allows easy PCB mounting and long-term durability. This versatile diode is commonly found in power supplies, communication devices, testing equipment, and educational electronics projects.
