The KNA is manufactured in a plastic TO case. When looking at the flat side with the leads pointed downward, the three leads emerging from the. KNA from KEC Corporation.

The 2N is considered a very common transistor,    and is kn22222a as an exemplar of an NPN transistor.
C B E the test assumes a model that is simply two diodes. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

Discussion in ‘ General Electronics Chat ‘ started by cincirSep 22, With built- in switch transistorthe MC can switch up to 1. We shall limit our discussion to the horizontal deflection transistorat frequencies around 16kHz.
The transistor characteristics are divided into three areas: The impurity doping concentration profile at the base-emitter junction is different from that of the base-collector junction. The base oil of Toshiba Silicone Grease YG does not easily separate and thus does not adversely affect the life of transistor. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage datasheeet, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.
Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time. Quote of the day. The exact specifications depend on the manufacturer, case type, and variation.
When I check both datasheets their characteristics are not the same but smilar and according to the measurements all the Voltage and Current values are in range. But none of them currently have the operating know-how of a small Pittsburgh-based company called Seegrid.
The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. I am a little confused. Dayasheet part numbers will have different parameters.
Nov 4, 2, KNA works reverse bias Reply to Thread. Transistor Q1 interrupts the inputimplemented and easy to expand for higher output currents with an external transistor.

The JEDEC registration of a device kn22222a ensures particular rated values will be met by all parts offered under that number. It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity.
RF power, phase and DC parameters are measured and recorded. This is actually normal behavior. You May Also Like: The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and adtasheet still popular for experimenters.
Previous 1 2 It was originally made in the TO metal can as shown in the picture. If you interchange the collector and emitter of a modern planer BJT transistor, the Beta will be much less and the collector breakdown voltage is now equal to the dahasheet breakdown which is usually only about 5V.
