Description

The DS20S is a silicon Schottky rectifier diode made by IPRS Băneasa [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the DS20S20, DS20S30, DS20S35, DS20S40 and DS20S45 among the „Schottky rectifiers” of its „Rectifiers” section [1]. Their values are under Variants [1]. In this table VF and IR are maximum values (at the IF and TJ given), VF0 is a typical value, trr is a maximum (in µs) and i²t is printed in kA²s [1].
