Note 1. The intristic standoff ratio, η, is essentially constant with temperature and interbase volt-
age. It is defined by the following equation:
Where
200
VP = η VBB + Tj
VP = Peak point emitter voltage
VBB = Interbase voltage
Tj = Junction Temperature (Degrees Kelvin)
Note 2. The interbase resistance is nearly ohmic and increases with temperature in a well–defined
manner. The temperature coefficient at +25°C is approximately 0.8%/°C.
