File No. 386 URC Solid State Division RF Power Transistors 2N3375 2N3553 2N3632 40665 40666 RCA 2N3632, 2N3553, 2N3375, 40665 and 40666 are epitaxial silicon n-p-n transistors of the overlay emitter electrode construction. They are intended for use in class A, B, and C amplifiers, frequency multipliers and oscillators, The 2N3375, 2N3553, and 40666 are es- pecially intended for VHF-UHF applications while the 2N3632 and 40665 are designed for use in VHF circuits. Ali the pins of the 2N3632 and 2N3375 are electri- cally isolated from the case. In the 40665 and 40666 (variants of types 2N3632 and 2N3375, respectively), the emitter is connected internally to the case.
