Die Spannungs- und Stromangaben sind als Betrag aufzufassen.
Vorzeichen müssen entsprechend Betriebsart und Polarität des Halbleitermaterials gesetzt werden.
Voltage and current ratings are given as magnitude, where the sign has to be set according to operating condition and polarity of the semiconductor material.
