PNP power bipolar transistor
High breakdown voltage VCEO = -230 V
Complementary to 2STC4793
High transition frequency, typical fT = 70 MHz
Audio power amplifier 2
Drive stage amplifier
This device is a PNP transistor manufactured
using new "PB-HDC" (power bipolar high density
current) technology. The resulting transistor Figure 1. Internal schematic diagram
shows good gain linearity behavior.
