There are different rules-of-thumb for amplifiers; one says that Ft should be five times the required upper frequency. On that basis the 2N3904 is suitable for up to about 60MHz whilst the SS9018 will serve at over 200MHz. 1996. 1. 28 1/3 semiconductor technical data kn3904 epitaxial planar npn transistor revision no : 0 general purpose application. switching application. 2N3705 Bipolar Transistors Page 3 09/05/08 V1.1 Specifications VCEO (V) VCBO Maximum (V) IC (mA) hFE Minimum at IC = 50mA fT Minimum (MHz) Ptot (mW) Pakage Part Number 30 50 0.8 50 100 625 TO-92 2N3705
