*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. 3) All voltages (V) and currents (A) are negative polarity for PNP transistors.

Frequently Asked Questions
What is the maximum continuous collector current rating?
The device has a nominal continuous collector current ($I_C$) of 200 mA.
Is this transistor suitable for life support systems?
No, its use as a critical component in life support devices requires express written approval from Fairchild Semiconductor Corporation.
How do I account for temperature changes when calculating power dissipation?
Above 25°C, the total device dissipation must be derated based on the rate of 2.8 mW/°C.
Can these absolute ratings be used if I operate it cyclically (pulsed operation)?
Engineers should consult the factory for applications involving pulsed or low duty cycle operations.
