A simple circuit diagram of the Class B amplifier with the using the S8050 is shown below. Like here the NPN transistor will be S8050 and its equivalent PNP transistor will be S8550. By complimentary it means that we need a NPN transistor and its equivalent PNP transistor. It is very simple to construct and requires two identical complimentary transistors operate. So let us discuss how that is done.Ī push pull amplifier, commonly known as Class B amplifier is type of multistage amplifier commonly used for audio amplification of loudspeakers. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region.Īs mentioned in the features the S8050 transistor is commonly used in push pull configuration with Class B amplifier. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (VCE) or Collector-Base (VCB) could be 20V and 30V respectively. When this transistor is fully biased then it can allow a maximum of 700mA to flow across the collector and emitter. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is 700mA, hence we cannot drive loads that consume more than 700mA using this transistor. However at a normal operating collector current the typical value of gain will be 110. See other products in this category: NPN SMD transistors YANGJIE TECHNOLOGY. Features: Collector-base voltage (VCBO): 40 V Collector-emitter voltage (VCEO): 25 V Emitter-base voltage (VEBO): 5 V Collector current (Ic): 0. It has a maximum gain value of 400 this value determines the. S8050 is a NPN surface mount epitaxial silicon transistor with low voltage, high current small signal.The device is designed for audio amplifier and general purpose applications. Since it is very high it is normally used for amplification purposes. YANGJIE TECHNOLOGY S8050-H Transistor: NPN bipolar 25V 0.5A 300mW. Reviews (0) The S8050 is an NPN transistor, so the collector and emitter will be left open (reverse polarized) when the base pin is held in the ground and closed (forward polarized) when a signal is provided to the base pin. It has a maximum gain value of 400 this value determines the amplification capacity of the transistor normally S8050. Operating Junction Temperature (Tj): 150 C Transition Frequency (ft): 150 MHz Forward Current Transfer. S8050 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.

Don't be stupid like me and assume everything is correct. ![]() So when adding a component in Kicad, please make sure that the pinout matches the datasheet, even if Kicad already seems to have the right component in the library. So I would've needed to use a BEC conponent.Īnd now i need to figure out how to either solder the transistor upside down or connect a THT transitor to SMD pads. But the SOT-23 ("J3Y") version of the transistor has the pins in BEC order. The S8050 THT transistor has the pins in EBC order, which is what the S8050 Kicad component uses. Yesterday I assembled it, and it doesn't work.Īfter a lot of stupid testing, I noticed that the transistor is connected incorrectly. I added a S8050 component in the schema and assigned the SOT-23 footprint and ordered the pcb. ![]() So I designed a PCB, which contains a S8050 transistor. ![]()
