BYV28/ is an ultra fast avalanche sintered glass diode produced by Vishay Semiconductors. It features controlled avalanche characteristic, low forward voltage, ultra fast recovery time, glass passivated junction, hermetically sealed package, lead (Pb)-free component, and it is in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC. It is mainly used for very fast rectification applications.
The BYV28 series are ultra‑fast avalanche sinterglass diodes with controlled avalanche characteristics, low forward voltage, and hermetically sealed, lead‑free packages. They are intended for very fast rectification in switch‑mode power supplies and similar applications.
The datasheet lists mechanical data (SOD‑64 case, 858 mg weight), electrical characteristics such as peak reverse voltage, forward current, forward voltage, reverse recovery time (30 ns), and thermal resistance. Compliance notes include RoHS and WEEE conformity, and a legal disclaimer limits liability for medical or life‑sustaining uses. This manual is written in Chinese.
