THERMAL RESISTANCE
SYMBOL
PARAMETER
Rth j-s
thermal resistance from junction to
soldering point
CONDITIONS
up to Ts = 135 °C (note 1)
Note
1. Ts is the temperature at the soldering point of the collector tab.

Tj = 25 °C unless otherwise specified.
SYMBOL
PARAMETER
ICBO
collector cut-off current
hFE
DC current gain
fT
transition frequency
Cc
collector capacitance
Ce

Cre
feedback capacitance
GUM
maximum unilateral power gain
(note 1)
F
noise figure
CONDITIONS
IE = 0; VCB = −10 V;
IC = −70 mA; VCE = −10 V
IC = −70 mA; VCE = −10 V;
f = 500 MHz; Tamb = 25 °C
IE = 0; VCB = −10 V; f = 1 MHz
IC = 0; VEB = −0.5 V; f = 1 MHz
IC = 0; VCE = −10 V; f = 1 MHz
IC = −50 mA; VCE = −10 V;
f = 500 MHz; Tamb = 25 °C
IC = −50 mA; VCE = −10 V;
