The 1N4148 is a fast switching diode designed for high-speed switching applications. It features a maximum DC reverse voltage of 100V and an average rectified current of 150mA. The forward voltage is typically 1V at 10mA, and the reverse recovery time is 4ns, making it suitable for high-frequency circuits.
The diode is housed in a DO-35 axial leaded package, which is through-hole mountable. It has a junction capacitance of 4pF at 0V and 1MHz, and can operate over a junction temperature range of -65°C to 175°C. The device is Pb-Free as per the datasheet.
Typical applications include general purpose switching, signal rectification, and clamping circuits. The small signal rating (≤200mA) makes it ideal for low-power designs where fast switching is required.
The maximum DC reverse voltage is 100V.
The average rectified current is 150mA.
The forward voltage is 1V maximum at 10mA.
The reverse recovery time is 4ns.
The 1N4148 is available in a DO-35 through-hole package with axial leads.
