Retrieved 26 March To confirm, you can double check with the hFE function if your meter has that. KSPA has a gain value of tothis value determines the amplification capacity of the transistor.
The Base-Emitter voltage of this transistor is 6V so you just have to supply 2222a voltage across the base and emitter of the transistor to induce a base current into the transistor.
Would you like to answer one of these unanswered questions instead? Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. Would I reuse it? It is designed for low to medium currenttranaistor powermedium voltageand can operate at moderately high speeds. They’re listed together because they’re complementary transistors. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.
KSPA Transistor Pinout, Features, Equivalent & Datasheet
The base will show a diode connection to both other pins, in only one polarity. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Every transistor has a gain h FE associated with it, which can be used to amplify voltage or current.
The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.
The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. The exact specifications depend on the manufacturer, case type, and variation. The 2N, 2N, and 2N devices, for hransistor, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.
This page was last edited on 25 Octoberat To distinguish collector from dtasheet, you look at the voltage shown in the diode function with the one successful test that found the base.
How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce.
In actual circuit modifications might be required. Hence the 2N pin-out is sadly not standardized. This transistor like all can be used either as a switch or as an amplifier. TL — Programmable Reference Voltage. There are many types of amplifier circuits that are possible with transistor but this is the most commonly used one because it is very good in amplifying low frequency voltage signals like audio signals. No other pin will show that.
The value for this resistor can be calculated using the formula. However one important thing to notice is the Base resistor a. Again the values of the resistor mentioned above datashedt only for reference commonly used you have to design your own circuit based on the application and transistor you are using.

Learn tdansistor keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: This is the picture of the datasheet for the pins: When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.
From Wikipedia, the free encyclopedia. But there are two important features that distinguish both.
