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.
