12/3/2023 0 Comments S8050 pinout![]() They can't map an analog voltage from one max voltage to another. So you don’t have to change anything regarding to pins when replacing the in a circuit and you can put them in the place of each other. The first pin is Emitter, second is Base and the third is Collector. Keep in mind that these level shifters are purely digital. The pin configurations of both the transistors are identical. Use as many of these channels as your project requires. DESCRIPTION The UTC S8050 is a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications. Something sent in HV3 will be shifted down and sent out of LV3. ![]() The S8050 transistor has a maximum collector current rating of 700mA, a maximum collector-emitter voltage. It is manufactured by multiple semiconductor companies, including Fairchild, ON Semiconductor, and STMicroelectronics. The number at the end of each label designates the channel of the pin, and the HV or LV prefix determines whether it's on the high or low side of the channel.Ī low-voltage signal sent in to LV1, for example, will be shifted up to the higher voltage and sent out HV1. S8050 is a general-purpose NPN transistor commonly used in electronic circuits as a switching or amplifying device. For better performance of S8050 transistor, it must operate in forward bias condition otherwise. These pins are labeled HV1, LV1, HV2, LV2, HV3, LV3, HV4, and LV4. Its perfect for level-shifting between devices that are sharing a data wire, like I 2 C. This converter can pass data from high to low and/or low to high on all channels. There are four separate data channels on the BD-LLC, each capable of shifting data to and from high and low voltages. Though theyre share the same shape and size, this bi-directional logic level converter shouldnt be confused with the more 'uni-directional' version. For example, if you're interfacing from 5V to 3.3V, the voltage on the HV pin should be 5V, and the voltage on LV sould be 3.3V. ![]() Figure 3: S8050 Transistor Pinout S8050 transistor Equivalent Transistors Figure 4: Several Transistors There are other transistors with a similar amplification capacity to the S8050. 2W Output Amplifier of Portable Radios in Class B Push. Here is a simple table showcasing the S8050 transistor pinout. The voltage supplied to the HV and GND inputs should be higher than that supplied to the LV side. Pin No Pin Name 1: Emitter: 2: Base: 3: Collector: C8050 Key Features. Supplying a steady, regulated voltage to both of these inputs is required. The pins labeled HV, LV, and two GND's provide high and low voltage references to the board. ![]() Let's look closer at some of the pin groups: Voltage Inputs The pins are labeled on both the bottom and top sides of the board, and organized into groups. ![]()
