Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end spc power amplifiers. It was produced exclusively by the Czechoslovakian electronics company Spe. The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell for less than one dollar, and became 23n955 industry workhorse standard.
