Diodes are important components in a wide range of electronics applications. Diodes used for radio-frequency (RF) applications, including the HSMs-282K-TR1G, operate differently than standard diodes. This article seeks to explain the application field and working principle of the HSMS-282K-TR1G diode.

Overview

The HSMS-282K-TR1G diode is a surface-mount, double-ended, planar structure Schottky diode. It is available in an SOT-143 package with a maximum junction temperature of +125°C. This diode finds use in RF applications, such as RF harmonic filtering, limiting, switching, and rectification.

Application Field

The HSMS-282K-TR1G diode is designed for commercial applications. It can be used in Bluetooth/Wi-Fi applications at frequencies up to 5 GHz. In addition, the diode can be used in automotive infotainment systems, consumer electronics, navigation equipment, and multimedia devices.

Working Principle

The HSMS-282K-TR1G diode is composed of a metal-semiconductor (Schottky) junction. When a forward voltage is applied to the diode, a current is generated as a result of the junction\'s barrier capacitance. This current is very fast and thus, is often used in high-speed switching applications. In addition, the diode exhibits very low forward voltage drop, making it ideal for RF rectification.

When a reverse voltage is applied to this diode, the junction capacitance is reversed and the diode behaves like an open circuit. This makes it ideal for applications such as harmonic filtering, where a very low level of current must be present. The low level of reverse current also ensures that oscillation is reduced, which can be a problem in some RF applications.

Conclusion

The HSMS-282K-TR1G diode is a surface-mount, double-ended, planar structure Schottky diode designed for commercial applications in RF applications such as RF harmonic filtering, limiting, switching, and rectification. It has a fast switching speed, low forward voltage drop, and low level of reverse current, making it ideal for these applications.
