1N4148 Description

Short technical summary and product information.

The 1N4148 is a fast switching diode from SMC Diode Solutions, designed for general-purpose switching applications. It features a peak repetitive reverse voltage of 75V, a forward continuous current of 300mA, and a reverse recovery time of 4ns, making it suitable for high-speed switching circuits.

 

Electrical characteristics include a forward voltage of 1V at 10mA, a reverse current of 5µA at 75V, and a junction capacitance of 4pF. The device can handle non-repetitive peak forward surge currents of 1A for 1 second and 2A for 1 microsecond. Power dissipation is rated at 500mW with a thermal resistance of 300°C/W junction-to-ambient.

 

The diode is housed in a DO-35 (DO-204AH) axial-lead glass package, suitable for through-hole mounting. It operates over a junction temperature range of -65°C to +175°C. The part is RoHS3 compliant (Pb-Free) and has an MSL of 1 (unlimited).
