Technical Specifications

The CD214A-B120 typically features a maximum repetitive reverse voltage (Vrrm) of 20V and a forward current (If) rating of 1A. The forward voltage drop is typically around 0.45V at 1A. It comes in a standard SMA (DO-214AC) package. It is important to consult the official datasheet for detailed electrical characteristics, thermal resistance, and package dimensions. Because this is an end-of-life product, sourcing may be limited and alternative components should be considered for new designs. The Schottky barrier construction results in very fast switching speeds compared to standard silicon diodes.

The CD214A-B120 offers a balance of performance and size, making it suitable for various power rectification applications. However, due to its end-of-life status, careful consideration should be given to its availability and potential replacement options.
