Overview
The onsemi 1N4148 is a ubiquitous small-signal switching diode, fundamentally designed for rapid signal rectification and switching applications. Its critical operational characteristic lies in its exceptionally fast reverse recovery time (trr) of 4 ns, enabling efficient high-frequency signal modulation and demodulation. A key design consideration when employing the 1N4148 in high-speed circuits is managing its inherent junction capacitance (4pF @ 0V, 1MHz), which can introduce parasitic phase shifts or signal attenuation if not properly accounted for in impedance matching and layout.
Key Features
- 100V DC Reverse Voltage (Vr)
- 200mA Average Rectified Current (Io)
- 1V Maximum Forward Voltage (Vf) @ 10mA
- 4ns Reverse Recovery Time (trr)
- 5µA Reverse Leakage Current (Ir) @ 75V
- 4pF Junction Capacitance (Cj) @ 0V, 1MHz
- Axial, DO-35 Package (5.2mm L x 2.7mm Dia)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
