Dimensions 1N4448 diode. Datasheet: Small Signal Diode Rev. I found some diode comparison charts online. A diode is a device which allows current flow through only one direction. The term switching and rectifier refer to how the didoe is normally used in a cicuit. The recommended largest reverse working voltage is given as 75 VDC. Looking at the Fairchild datasheet , the guaranteed max capacitance is less for the 916A/B and 4448 than the 914A/B/4184 (2pF vs. 4pF), and the forward voltage min/max ratings differ, but there's nothing I see that prevents them all from being made with a single die . I hope you will be absolutely fine and having fun. Only difference is that 1n4148 has low leakage current than 1n914, but even for some manufacturers the leakage current is same for both the diodes. Dear all, Given the success in the last thread on transistors, I thought I would ask about SMT variants of the venerable 1N4148 diode..

GENERAL RULE: The Reverse Current of a diode will approximately double for every ten (10) Degree C increase in Temperature Figure 2. Thanks. I got as far as the MMSD4148, but I suspect there are other "common" old-school diodes that have been converted to SMT.. Hello everyone! 1N914 diode, which is compatible with the 1N4148 diode ;) So the 1S2374 is a plain normal diode and couldn't even be a Schottki diode, as I learned the reverse current leakage of those diodes would ruin the non-chargeable Lithium cell when used in a battery backup circuit.
