BF556A,215 Discrete Semiconductor Products

BF556A,215 is an N-channel Enhancement-mode Silicon Gate MOSFET used in wide range of RF applications. It is designed for high-frequency applications from 10 to 110GHz and is manufactured using the Ion Implanted Metal Oxide Semiconductor (IIMOS process). This device features high reliability, low thermal resistance and low power consumption, as well as low on-resistance and high breakdown voltage.

The working principle of BF556A,215 is based on the application of electric field in the junction between the gate and the source electrode. When an electric field is applied, electrons in the gate and the source electrode interact, creating an electric charge distribution imbalance within the MOSFET, allowing current to flow through the device. This electric field is created by applying a gate voltage which controls the amount of charge that can flow through the MOSFET.

The low gate-drain capacitance and low capacitance density of BF556A,215 make it suitable for high-frequency applications like radio-frequency (RF) applications. These applications include amplifier circuits for radio receivers, Wireless local area networks (WLANs), Direct-sequence Spread-spectrum (DSSS) systems, and other high-frequency applications such as radar, communication systems, and biomedical applications. The capability of this device to handle large signal-to-noise ratios, with high switching rates and low power consumption, without sacrificing performance make it ideal for these applications, where the efficiency of the system is a criterion.

Overall, BF556A,215 is an ideal device for RF applications, as it offers high reliability, low thermal resistance, low power consumption, low on-resistance, and high breakdown voltage. It is also suitable for high-frequency applications such as radio receivers and wireless local area networks, as it features low capacitance density and low gate-drain capacitance.
