Rated at 100V and 150mA with a 4 ns reverse recovery time, this diode is one of the most versatile components in electronics design. The SOD-323 package provides a compact footprint for automated SMT assembly while maintaining the electrical characteristics that have made the 1N4148 series ubiquitous. With low junction capacitance of 2 pF and low forward voltage of 1.0V at 10mA, the device is well-suited for general-purpose switching, signal clamping, and small signal rectification in virtually all categories of electronic products.","working_principle":"The 1N4148WX-TP is a silicon epitaxial planar diode that conducts current in the forward direction when the anode voltage exceeds the cathode by approximately 0.6-1.0V. In the reverse direction, the diode blocks current up to 100V with leakage below 1 uA. The fast 4 ns reverse recovery time results from the small junction area and optimized epitaxial structure, which minimizes stored charge that must be removed during switching transitions. When the diode transitions from forward conduction to reverse blocking, the reverse recovery current briefly flows as stored minority carriers are swept out of the junction region. The small junction area also results in low capacitance (2 pF), making the diode suitable for high-frequency signal applications.","pin_description":"\n
