Note 3. | The internal Collector-to-Emitter diode can eliminate the need for an external diode to clamp inductive loads. Tests have shown that the Forward Recovery Voltage (Vf) of this diode is comparable to that of typical fast recovery rectifiers. |
Anmerkung zu den NTE/ECG Austauschhalbleiter:
NTE-Austauschhalbleiter (früher ECG Philips und Sylvania) sind sorgfältig
ausgesuchte und erprobte Halbleiter, die einen sicheren Ersatz
für Originaltypen verschiedenster Hersteller und Ursprünge für
fast alle Applikationsbereiche im Wartungsdienst bieten.
Alle NTE-Austausch-Halbleiter sind einzeln in durchsichtigen
Plastikbeuteln verpackt, auf welchen die wichtigsten Daten
vermerkt sind.
Falls Sie einen Halbleiter suchen, können Sie entweder die NTE QuickCross
Software bei uns als CD kaufen (Best.Nr. 08.NTE.CD) oder
sie gratis vom Internet runterladen.
