Sourced from Process 23 and 66. See FFB3904 (NPN) and FFB3906 (PNP) for characteristics. Absolute Maximum Ratings* Symbol TA = 25°C unless otherwise noted Parameter Value Units VCEO Collector-Emitter Voltage 40 V VCBO Collector-Base Voltage 40 V VEBO Emitter-Base Voltage 5.0 V IC Collector Current - Continuous 200 mA TJ, Tstg Operating and Storage Junction Temperature Range -55 to +150 °C *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.
