Diodes - Rectifiers - Single

The BAT54J/ZLX is a single diode rectifier developed by ON Semiconductor, which is widely used in various electronic applications. It is classified as a compact surface-mount device that uses package sizes as small as the SOT-23 package, reducing the space needed for assembly on a printed circuit board and providing a cost-savings benefit when compared to larger packages. This device is used as a bridge rectifier in a variety of electronic products and is specified as a non-isolated rectifier due to its low isolation voltage (V isolation min = 5V).

Features

The BAT54J/ZLX offers several advantageous features that make it an attractive choice for designers in the electronics industry. The product offers a wide operating temperature range from -55°C to 150°C with a maximum forward voltage drop (VF) of 0.55V @ IF = 30mA. Additionally, the BAT54J/ZLX is a RoHS-compliant part, meaning it meets all criteria for being lead-free and halogen-free. Finally, the BAT54J/ZLX has superior surge capabilities and a low leakage current (IR) of 0.75 µA @ Vf = 5V.

Applications

The BAT54J/ZLX is commonly implemented in applications where space is at a premium, such as automobile electronic controlled applications, LCD display systems and cell phones. It is also used in power supplies, DC-DC converters and power inverters. The BAT54J/ZLX meets the needs of both high-voltage and low-voltage applications, making it appropriate for systems that require 4V to 30V operation.

Working Principle

A single diode rectifier like the BAT54J/ZLX is essentially a semiconductor device that uses a junction or pn junction to convert AC to DC. The diode acts as a one-way valve that only allows current to pass in one direction. If the voltage or current level is too high, the diode will not allow current to pass through and will become non-conductive. In the BAT54J/ZLX, the device consists of an anode, cathode, and junction, and when connected to a power source, an external electrical field will cause electrons to flow from the anode to the cathode.

The current flows from the anode to the junction and through the diode until it reaches the cathode, where the current flow stops and the circuit is said to be in its solution state. This process will continue until the current reaches the limit set by the device\'s junctions, at which point the circuit is said to be in the breakdown state. During this process, the diode will act as a rectifier and the incoming AC current will be converted to DC current.

Conclusion

The ON Semiconductor BAT54J/ZLX is a single diode rectifier that offers a host of features that make it attractive to designers in a variety of application areas. It offers a wide operating temperature range and low leakage current, while its small package size makes it perfect for applications where space is at a premium. Its ability to convert AC to DC has made it a valuable component in the electronics industry, and it is widely used in various electronic applications such as LCD displays, power supplies, and DC-DC converters.
