Slkor Medium Voltage MOSFET BSS138 specification
The Slkor Medium Voltage MOSFET BSS138 meets the voltage and current requirements of most LED driver circuits. With a maximum voltage rating of 50V, it's suitable for use in low to medium voltage applications, while its maximum continuous current rating of 220mA makes it suitable for driving medium-brightness LEDs. Additionally, its low on-state resistance results in minimal heat generation during conduction, thereby improving the overall efficiency of the LED driver circuit and showcasing its efficient current-carrying capability. Moreover, it features a low threshold voltage, which helps reduce power consumption in the driver circuit. Lastly, its maximum power dissipation during operation is 225mW, ensuring stability under normal operating conditions.
Parameters of Slkor Medium Voltage MOSFET BSS138
The Slkor Medium Voltage MOSFET BSS138 is highly suitable for LED driver circuits. The primary purpose of an LED driver circuit is to provide a stable current to the LED, ensuring its proper illumination. The medium voltage N-channel MOSFET, with its low on-state resistance and high efficiency characteristics, proves to be an ideal choice for achieving this objective. It functions as a switching device in the LED driver circuit, regulating the drain current by controlling the gate voltage, thereby enabling precise control of the LED current. When the gate voltage exceeds the threshold voltage, the MOSFET turns on, allowing current to flow from the source to the drain, thus driving the LED to emit light. Conversely, when the gate voltage falls below the threshold voltage, the MOSFET turns off, causing the LED to turn off as well.
