Normally this type of transistor will either be used as a switch or as an amplifier, both of which is discussed below. The ttransistor pin of the transistor has to be biased with a voltage; this voltage is provided by the potential divider network formed by the resistors R4 and R6.

Home Questions Tags Users Unanswered. TL — Programmable Reference Voltage. But there are two important features that distinguish both. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. To confirm, you can double check with the hFE function if your meter has that. Junkbots, bugbots, and bots on wheels: TL — Programmable Reference Voltage.

KSPA Transistor Pinout, Features, Equivalent & Datasheet

What do you think? To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Submitted by admin on 24 June Zuofu 3, 2 15 The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

Javier Loureiro 1 7 If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor.

Would I reuse it? Again the values of the resistor mentioned above are 222a2 for reference commonly used you have to design your own circuit based on the application and dataasheet you are using. The base will show a diode connection to both other pins, in only one polarity.

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. They’re listed together because they’re complementary transistors. Commercial transistors Bipolar transistors. KSPA can allow dataasheet current upto mA and also has power dissipation of mW which can be used to drive larger loads than compared with BC The value for this resistor can be calculated using the formula.

You can have up to 3 types of configurations. But there are two important features that distinguish both. Submitted by webmaster on 11 December Archived from the original on 14 April To make things simple I have shown a simplified circuit to make a transistor as switch.

Graf and William Sheets It is used in a variety of analog amplification and switching applications.

ST Microelectronics

Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors. 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. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

Retrieved from ” https: I don’t think so – throw it in the bin. From Wikipedia, the free encyclopedia. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. 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. Would you like to answer one of these unanswered questions instead?

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. 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 are still popular for experimenters.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. I am trying to figure out what is going on here.

The JEDEC registration of a device number ensures particular rated values will be met by all parts offered datashedt that number. I have used a base voltage of 5V and a value of 1K as current limiting resistor.

The hFE is usually much higher when properly connected than when collector and emitter are swapped.
