The NTE384 is a multiple epitaxial silicon NPN power transistor in a TO66 type package utilizing a multipleemitter site structure. Multipleepitaxial construction maximizes the voltampere characteristic of the device and provides fast switching speeds. Multipleemitter design ensures uniform current flow throughout the structure, which produces a high IS/b and a large safeoperationarea. The NTE384 is characterized for use in inverters operating directly from a rectified 110V power line. The leakage current is specified at 450V; therefore the device can also be used in a series bridge configuration on a 220V line. The VEBO rating of 9V eases requirements on the drive transformer in inverter applications.
