| FZT749 Discrete Power & Signal Technologies July 1998 FZT749 C E B C SOT-223 PNP Low Saturation Transistor These devices are designed with high current gain and low saturation voltage with collector currents up to 3A continuous. Absolute Maximum Ratings* Symbol VCEO VCBO VEBO IC TJ, Tstg Parameter Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25C unless otherwise noted FZT749 25 35 5 3 -55 to +150 Units V V V A C Operating and Storage Junction Temperature Range *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 150C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
