TN6728A / NZT6728
TN6728A
PNP General Purpose Amplifier
This device is designed for general purpose medium power
amplifiers and switches requiring collector currents to 1.0 A.
Sourced from Process 78.
Absolute Maximum Ratings*
TA = 25C unless otherwise noted
*
These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
