2N3904 / MMBT3904 / PZT3904
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.
Absolute Maximum Ratings* Ta = 25°C unless otherwise noted
Collector Current - Continuous
Operating and Storage Junction Temperature Range
-55 to +150
* These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
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
