CD214A-B340LF Datasheet/PDFDiodes - Rectifiers - Single
The CD214A-B340LF is a single phase, 1200V blocking, 8A average rectifier diode from Central Semiconductor Corporation. It is commonly used in high speed rectification in switched mode power supplies, input/output for utility meters, converters, rectification and freewheeling applications. When used in DC-to-DC converters, it is most effective for achieving higher frequency operation with low losses. With its excellent power dissipation capability and surge immunity, it is especially ideal for pulse-width modulation control and noise reduction.
Working Principle of CD214A-B340LF
The CD214A-B340LF diode is a voltage-controlled semiconductor device that works as an electronic switch. The device consists of a N-type semiconductor layer connected to a P-type semiconductor layer. When a high voltage is applied across the junction of the two layers, the diode will turn on, or “forward bias,” and current can flow in a single direction. When the voltage across the junction reverses, the diode will turn off, or “reverse bias,” and the current will stop.
The unique and beneficial characteristic of this rectifier diode is that it can handle large and sudden voltage spikes with ease. This means it can be used as an efficient noise reduction and surge protection component as well. The CD214A-B340LF can handle up to 3kV of transient voltage without any safety hazard.
