HISTORIC NOTES

Sylvania introduced the first commercial germanium crystal diode in 1946, with the famous 1N34.  This was a general purpose diode that found widespread use in numerous commercial and hobbyist applications.  Sylvania expanded this successful line of devices with additional types, such as the 1N38, 1N39, 1N40 thru 1N42, and 1N54 thru 1N58.  These first Sylvania diodes used large white ceramic cases.  By 1949, Sylvania began to offer smaller, lighter weight versions of these diodes with hermetically sealed glass cases – these newer devices were designated with the letter “A” following the original device number, so that the 1N34A was the glass-cased version of the original ceramic-cased 1N34.  The glass diodes were a commercial success, and Sylvania continued to produce even smaller devices throughout the 1950s.  The 1N34A is a rugged, high performing germanium diode, electrically equivalent to the original 1946 1N34 diode, and useful in a wide variety of historic and modern applications.  Although manufactured over 50 years ago, most 1N34A Sylvania diodes are still functional, and will provide quite excellent results when used in circuit applications of the time, such as the classic crystal diode AM radio receiver built by thousands of engineers and hobbyists since the 1950s.
