High-speed diodes
The 1N4148 and 1N4448 are high-speed switching diodes fabricated in planar technology, and encapsulated in hermetically sealed leaded glass SOD27 (DO-35) packages.
For efficiency and logistic reasons the manufacturing and selling of products of the glass-diode type family 1N4148 is taken over completely by TAK CHEONG under license of Nexperia, where it has been manufactured already since year 2003.
This includes also the complete customer support like product information, complaint issue handling, application support etc.

Longevity
The Nexperia Longevity Program is aimed to provide our customers information from time to time about the expected time that our products can be ordered. The NLP is reviewed and updated regularly by our Executive Management Team. View our longevity program here.
How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
