   Audio power amplifier                                                     TO-247


Description
                                                          Figure 1.   Internal schematic diagram
The device is a NPN transistor manufactured
using new BiT-LA (Bipolar transistor for linear
amplifier) technology. The resulting transistor
shows good gain linearity behaviour.
Recommended for 70 W to 100 W high fidelity
audio frequency amplifier output stage.
