These types differ in voltage ratings and in the current at which the parameters are controlled. The 40542 is intended as a complement to p-n-p type 40051 in complementry-symmetry output stages of audio-amplifier circuits. The 40543 was designed specifically for amplifier applications. *Data for type 40051 appears in File No. 67. ·*"HOMETAXIAL" was coined by RCA from two words, "homogeneous" and "axial," to provide a name for a transistor structure in which the base region comprises homogeneous resistivity silicon material in the axial direction {emitter...to-collector}. Hometaxial types provide greater power-han.
