Description

BYW85C is Telefunken Silicon Mesa Rectifier. An avalanche diode is a type of diode that is designed to operate in a region of its voltage-current characteristic where a phenomenon known as “avalanche breakdown” occurs. Avalanche breakdown is a process in which a small initial current or voltage causes a rapid and self-sustaining increase in current. This breakdown phenomenon is a result of impact ionization, where energetic electrons collide with atoms in the semiconductor material, freeing additional electrons and leading to a rapid increase in current.

Description

FMGG26 is Ultra-Fast-Recovery Rectifier. ( Diode ). An Ultra Fast Recovery Rectifier (UFRR) is a type of semiconductor diode designed to have an extremely fast reverse recovery time compared to standard rectifier diodes. Reverse recovery time refers to the time it takes for a diode to switch from the conducting (forward-biased) state to the non-conducting (reverse-biased) state when the polarity of the voltage across the diode is reversed.

1. Fast Recovery Time: The defining feature of UFRRs is their exceptionally fast reverse recovery time, often measured in nanoseconds (ns) or less. This fast switching capability minimizes switching losses and reduces the potential for electromagnetic interference (EMI) in high-frequency applications.

2. High-Frequency Operation: UFRRs are well-suited for high-frequency applications where rapid switching is required. They are commonly used in switching power supplies, high-frequency inverters, and high-speed rectification circuits.

3. Low Forward Voltage Drop: UFRRs typically have a lower forward voltage drop (forward voltage) than standard rectifiers. This characteristic helps reduce conduction losses and improves overall efficiency in power conversion applications.
