Mr. Song Shiqiang, the General Manager of Slkor (www.slkoric.com), stated that social progress is driven by successive advancements in technology, which in turn promote changes in production relations and propel socio-economic development. Leveraging the vast domestic market and internal economic circulation, there lies a favorable opportunity for domestic substitution in the field of electronic components and electronic information products. For the Chinese nation to rise again and achieve great rejuvenation, it is essential to seize the upcoming new wave of "Kangbo cycles" and strengthen the development of the electronic information industry to achieve "indigenous controllability" at critical technological nodes. As a well-known semiconductor company, Slkor offers a variety of products such as voltage regulator diodes to meet the diverse needs of different applications.

The Slkor Voltage Regulator Diode 1SMA4728A features a maximum power dissipation of 1W and a stable voltage value of 3.3V. The device operates within a voltage stability range of 3.1V to 3.5V, with a reverse leakage current of 100μA.The voltage regulator diode plays a crucial role in battery chargers, providing functions such as over-voltage protection, voltage regulation, and current limiting. This enhances the safety and efficiency of the charger.

Slkor Voltage Regulator Diode 1SMA4728A specification

The power limit of the Slkor Voltage Regulator Diode 1SMA4728A is 1W, ensuring that the diode does not overheat under normal operating conditions. This reduces the need for additional cooling devices such as heat sinks and fans, simplifying the thermal design of the circuit. Featuring a small plastic package suitable for surface mount designs, this diode can be easily integrated into compact electronic devices. Surface mount design is a common approach in modern electronics assembly, improving assembly density and reliability while saving space and reducing weight, making it particularly suitable for applications with strict size and weight requirements. The plastic package offers good insulation and corrosion resistance, protecting the internal voltage regulator diode from external environmental factors and prolonging its lifespan.

Parameters of Slkor Voltage Regulator Diode 1SMA4728A

The application of the Slkor Voltage Regulator Diode 1SMA4728A in battery chargers primarily involves over-voltage protection. In the circuit of a battery charger, the voltage regulator diode can serve as an over-voltage protection component. When the output voltage exceeds a certain threshold, the voltage regulator diode undergoes reverse breakdown, stabilizing the voltage at a preset level to safeguard the battery from over-voltage damage. Additionally, it provides voltage regulation by ensuring a stable output voltage, thereby enhancing charging efficiency and prolonging battery life. Lastly, it offers current limiting functionality, reducing the current in the circuit when it exceeds safe levels to protect both the battery and the charger.
