| PN918 / MMBT918 Discrete POWER & Signal Technologies PN918 MMBT918 C E C B TO-92 E SOT-23 Mark: 3B B NPN RF Transistor This device is designed for use as RF amplifiers, oscillators and multipliers with collector currents in the 1.0 mA to 30 mA range. Sourced from Process 43. Absolute Maximum Ratings* Symbol VCEO VCBO VEBO IC TJ, Tstg Collector-Emitter Voltage Collector-Base Voltage Emitter-Base Voltage Collector Current - Continuous TA = 25C unless otherwise noted Parameter Value 15 30 3.0 50 -55 to +150 Units V V V mA 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 150 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
