SL1M - when one diode can replace several types

If you have in your „drawer“ a universal 1000V diode in a miniature SOD123FL package, you have a solution for many circuits.

Small/ bigger, with a lower- or rather with a higher cut-off voltage, solderable by wave or by reflow … these are for example some of the criteria when selecting a universal rectifying diode. However if you already know, that 1A current and a middle speed are sufficient for you, then we can say, that only one type will be sufficient for you in majority of cases - SL1M from company Diotec.

Standard silicon diodes show only a minimal dependency of VF from a cut-off voltage - in opposite to Schottky diodes, where a choice according a cut-off voltage is important in order to reach low losses (as a forward voltage - VF is noticeably higher at types with a higher cut-off voltage).

In other words, if a Schottky diode transfers for example 1A current, there´s a significant difference in a VF between types with a lower cut-off voltage in comparison to types with a higher cut-off voltage. However common silicon diodes don´t have this dependency, thus in general it dosen´t matter, whether we´ll use a „100V“ diode or a „1000V“ diode on a given place (if we don´t use a possible breakdown intentionally). So if can choose between a 400V and 1000V type for a similar price, nothing prevents us to better buy a 1000V type and to have a surety of universal usage - for example even for a direct rectification of a mains voltage. As a result we´ll gain for example a higher resistance to various overvoltages.

SL1M offers such versatility thanks to a very good price and also thanks to its dimensions, because it belongs to the smallest 1A diodes in the market. The only requirement if we want to use a maximum current of 1A is, that it´s necessary to observe a minimal pad dimensions (copper area) of approx. 5x5mm at both sides. This won´t be a problem for the most of applications, as to this area also contribute surrounding solder pads of other components (if they don´t generate heat). Naturally, in this case we mustn´t use at the PCB design a thermal isolation of pads (so called thermals), but only a non-solderable layer (solder resist).
