The Slkor Voltage Regulator Diode ZMM3V9 has a maximum power dissipation of 500mW and a stable voltage value of 3.9V. Its operating voltage range is from 3.7V to 4.1V, with a reverse leakage current of 2μA. This Voltage Regulator Diode features boasts excellent voltage stability, capable of maintaining a stable output voltage under various operating conditions, thereby ensuring stable illumination of the LED.
Slkor Voltage Regulator Diode ZMM3V9 specification
The Slkor Voltage Regulator Diode ZMM3V9 particularly in MiniMELF packaging, is well-suited for automatic insertion. When packaged in MiniMELF, the ZMM3V9 can be more accurately positioned and aligned in automatic insertion equipment, significantly improving production efficiency and assembly precision. Furthermore, its zener voltage is graded according to the international E24 standard. The E24 standard is a widely used standard for resistor values, specifying a series of preferred values that can be achieved more precisely during manufacturing, thereby ensuring product performance consistency. A smaller voltage tolerance and higher zener voltage indicate a more stable output voltage for this diode, making it suitable for applications with high demands on power supply accuracy. Additionally, it can meet the requirements of some special applications that need high voltages, such as high-voltage power supplies and high-power circuits.
Parameters of Slkor Voltage Regulator Diode ZMM3V9
The application of the Slkor Voltage Regulator Diode ZMM3V9 in LED drivers encompasses several aspects. Firstly, it enables current stabilization control. In LED driver circuits, this diode can be utilized to create a constant current source, achieving high-precision control of LED operating current. This ensures the LED operates under a constant current, thereby enhancing its luminous stability and lifespan. Secondly, it provides overvoltage protection. When the power supply voltage exceeds the LED's tolerance range, the device conducts, diverting the excess voltage to ground, thus safeguarding the LED from damage. Lastly, it simplifies circuit design. By leveraging its stable voltage characteristics, the design of LED driver circuits can be simplified, eliminating the need for complex circuitry to achieve voltage stabilization and ensuring stable voltage output.
