نظرة عامة على المنتج
The 1N4148WS is a high-speed switching diode from ON Semiconductor in a compact SOD-323 surface-mount package. It is the SMD equivalent of the classic 1N4148 through-hole diode, offering 100V reverse voltage, 150 mA average forward current, and fast reverse recovery time of 4 ns. Ideal for general-purpose switching, signal routing, and protection in space-constrained PCB designs.
