Diodes - Rectifiers - Arrays: FST12080 Application Field and Working Principle

The FST12080 is a high-temperature, high-efficiency diode rectifier array in a hermetically sealed and industry-standard, three-lead package. The FST12080 is designed for bi-directional, high-frequency radio frequency (RFI) and EMI filtering in applications such as power supplies, cell phones, notebook systems, cameras, and other small electronics devices, especially those that need to operate in high-temperature, top-notch performance.

The products realize lowest output ripple amplitude and good temperature stability with their high temperature, large junction-to-case thermal resistance and wide operating temperature range of -55 °C to 200 °C. This device is suitable for use in harsh environments and meet all necessary requirements for industrial, military and aerospace applications.

Application Areas

The FST12080 has a wide range of applications, including consumer and industrial electronics, such as power supplies, LED driver circuits, and wireless communications. The device can be used for high-efficiency rectification of AC/DC, signal conditioning, and other special purpose filtering applications. The FST12080 is also suitable for off-line synchronous rectification control and active power factor correction applications.

Working Principle

The FST12080 is a three-terminal device with two possible input sources supported. The inputs can be either direct current (DC) or alternating current (AC). The device can be used to rectify both AC and DC signals, providing the necessary electrical characteristics to deliver a steady and reliable voltage output.The FST12080 consists of an anode, a cathode, and a gate, which provide bi-directional current rectification for ridliebs and high-efficiency conversion. It has two diodes, one in an anode-cathode configuration and the other in a cathode-gate configuration. The anode-cathode diode is turned on to allow current to flow from the anode to the cathode, while the cathode-gate diode is turned off to block any current from flowing from cathode to gate.

The FST12080 also offers a number of features that make it a must-have device in application designs. It has a low reverse leakage current, low zero voltage switching, high thermal resistance, and an adjustable current-blocking capability. Additionally, the FST12080 is rated for use in temperatures between -55 °C and 200 °C.

Conclusion

The FST12080 provides an effective and efficient solution for rectification and filtering applications in consumer and industrial electronics products. Its bi-directional function produces high-quality DC output, its low leakage current ensures clean power, and its wide operating temperature range makes it suitable for harsh environments. In addition, the device is rated for use in challenging atmospheres, making it a reliable and durable choice for various applications.
