High power NPN epitaxial planar bipolar transistor
High breakdown voltage VCEO = 140 V
Complementary to 2STW1695
Typical ft = 20 MHz
Fully characterized at 125 oC
Audio power amplifier TO-247
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.
