As the praxis has shown, both Technologies have their stable place in the production of electronics. This is also confirmed by a known fact, that the highest density of components on a single-sided PCB can be reached by a combination of SMT and THT components, when the THT components on the rear side also act as „PCB tracks“.
To many components, which we have in both SMT and THT version, we incorporated a well-known favorite diode 1N4148 in an SMT sod123 package - 1N4148W. It is a universal switching (small signal) diode with a small PN junction capacitancy, thus suitable even for fast circuits. Small leakage current ensures a minimum influence of surrounding circuitry, that´s why the 1N4148 is often used also as a protective diode for protection of digital circuits inputs. Next time, when you´ll design a device with a 1N4148, try to consider, whether an SMT version wouldn´t suit better to you - 1N4148W, LL4148 (miniMelf), TS4148 or other versions.
