BAT17,235 Datasheet/PDFBAT17, 235 Application Field and Working Principle
BAT17,235 is a fast switching diode that can be used in many different applications. The device has a unidirectional blocking capability up to 200V. It can also handle up to 5A of current and is generally used in power supply and voltage regulator designs.
The main application areas of BAT17,235 are in power supplies, voltage regulators, protection and regulation circuits. The diode is also used in RF systems such as wireless data networks, wireless LANs, and CDMA systems. The BAT17,235 diode provides reliable protection against impulse noise, rectification of an AC signal, and many other useful applications.
Working Principle
BAT17,235 is an amplitude or frequency limited diode. It is a p-n-p-n type device comprising four diodes. The four diodes, each in series with a resistor, provide two resistive negative feedback loops. In most applications, the two feedback loops act as anti-saturation protection by quickly limiting reverse bias transfer characteristics, as well as providing EMI (Electro-Magnetic Interference) immunity.
The BAT17,235 diode is typically used in devices or circuits with alternating input signals such as a clock circuit or an active/passive filter. In these applications, the diode works as a voltage limiter and a low-impedance device which efficiently reduces the EMI (Electro-Magnetic Interference) caused by the large dV/dt and the high-frequency noise caused by the supply oscillations.
