Diodes - Rectifiers - Arrays encompass many diode and rectifier types each with specific application purposes, from high-speed signal switching to protection from overload and reverse polarity. One such device is the 1PS300/ZLX, a planar Schottky rectifier for power management.

The 1PS300/ZLX is an ultra-low-voltage rectifier diode produced by ON Semiconductor, and manufactured on a planar process optimized for increased efficiency, less power loss, and minimized thermal resistance. This device is designed to minimize switching and conduction loss while simultaneously providing fast switching speeds and low reverse recovery times with good thermal performance.

In terms of its application field, 1PS300/ZLX rectifiers are intended to package 1A of current with a maximum voltage rating of 250V. As mentioned previously, this device is particularly well-suited for power management applications such as DC/DC converters, switch mode power supplies, and voltage regulation. Additionally, this device is well-suited for ultra-high frequency applications, such as hand-held cordless phones, where low power consumption and a compact package are key requirements.

The 1PS300/ZLX features an ultra-low VF, which enables the device to operate with very little voltage drop. This reduces the overall power consumption of the circuit, making it particularly suitable for power management applications. The device also features a “softness” which helps to reduce the EMI emissions of the circuit, further improving the efficiency and reliability of the system.

The 1PS300/ZLX can be used in rectifier applications, making use of the diode’s low VF to decrease conduction losses. Additionally, the low capacitance of the device aids its use in high frequency applications. The diode can also be used in an array configuration, allowing for higher current and voltage ratings with minimal power loss.

The working principle of the 1PS300/ZLX is based on the same principles as other high-performance rectifiers. Under forward bias, current is allowed to flow from the anode (positive) to the cathode (negative). Under reverse bias, the device exhibits a very high breakdown voltage, blocking the flow of current. The device also features a low reverse leakage current, enabling it to effectively prevent reverse-polarity damage to the circuit.

In summary, the 1PS300/ZLX is a planar Schottky rectifier designed for use in power management applications. This device features an ultra-low VF and low capacitance properties, helping to reduce conduction and EMI losses while providing high-speed switching and low reverse recovery times. The device boasts a high voltage rating and can be used in both rectifier and array configurations depending on the required application.
