1N4148WT

1N4148WT Description

The 1N4148WT from SMC Diode Solutions is a high-performance, surface-mount general-purpose switching diode designed for small-signal applications. With a 75V DC reverse voltage (Vr) and 150mA average rectified current (Io), it offers reliable performance in fast-switching circuits. The diode features a low forward voltage drop (1.25V max @ 150mA) and ultra-fast reverse recovery time (4 ns), making it ideal for high-speed signal processing. Its 2pF low junction capacitance (@ 0V, 1MHz) minimizes signal distortion, while the automotive-grade qualification ensures robustness in harsh environments. Packaged in SOD-523 (Tape & Reel), it is optimized for automated PCB assembly.

1N4148WT Features

• High-Speed Switching: 4 ns reverse recovery time (trr) for fast signal processing.
• Low Leakage: 1 µA max reverse leakage (@ 100V) ensures power efficiency.
