2N5179 datasheet



This is 12V, 50mA, NPN RF Transistor. The CENTRAL SEMICONDUCTOR 2N5179 type is a silicon NPN RF transistor, manufactured by the epitaxial  planar process, designed for VHF/UHF amplifier, oscillator, and converter applications.


1. It is a common and widely available transistor, which makes it easy to find and use in electronic projects.

2. It has a high gain, which is beneficial for amplification in RF applications.

3. The transistor is relatively inexpensive, which makes it a cost-effective option for various electronic projects.

4. It has a relatively low collector current rating of 50 mA, which limits its use in high-current applications.

5. It is not suitable for use in power amplifiers due to its low power dissipation rating.

6. The transistor has a limited voltage rating of 30 V, which may not be sufficient for some applications.
