ER RACEMIC TRS 2N4124 MMBT4124 c B SOT-23 B Mark: ZC E NPN General Purpose Amplifier This device is designed as a general purpose amplifier and switch. The useful dynamic range extends to 100 mA as a switch and to 100 MHz as an amplifier. Sourced from Process 23. See 2N3904 for characteristics. TA = 25C unless otherwise noted Absolute Maximum Ratings* Discrete POWER & Signal Technologies Symbol Parameter Value Units Voeo Collector-Emitter Voltage 25 Vv Veso Collector- Base Voltage 30 Vv VeBo Emitter-Base Voltage 5.0 Vv Io Collector Current - Continuous 200 mA Ty, 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.
