824500851 Circuit Protection

TVS (Transient Voltage Suppressor) diodes are a type of protective device typically used for over-voltage and surge protection. They are unidirectional devices that protect against electrical transients in frequencies from transient line interferences to high-speed data transmission lines. The 825500851 is a TVS diode designed to protect electronic equipment against voltage spikes that can occur during power-up or brown-out events. This diode is also ideal for protecting devices with high current or high voltage applications, such as those used in automotive applications.A TVS diode consists of an epitaxial PN junction, which works by diverting electrical transients away from an electrical circuit and into the diode. This works in a similar way to a diode bridge, where an electrical current is diverted in one direction when the voltage is greater than the diode\'s breakdown voltage. The 824500851 is designed with a breakdown voltage of 64V, and is capable of handling up to 8 A of current.When the voltage across the diode exceeds its breakdown voltage, it becomes a low-impedance connection, allowing electrical transients to travel through it and away from the protected circuit. This same process also happens when the voltage across the diode falls below its reverse breakdown voltage. The 824500851 is designed with both a reverse breakdown voltage of 30V and a reverse-leakage current of 150 nA (nan amperes). The leakage current is the amount of current flowing through the diode when it is in the reverse-biased state.Other features of the 824500851 include its clutch function, which prevents the diode from shorting out when the voltage surge is greater than the diode\'s breakdown voltage. The diode is also protected against reverse polarity, thanks to its SOT-23 packaging. This packaging also helps to reduce the diode\'s thermal resistance, and helps to keep it from heating up due to its own current drain.In addition to protecting circuits from over-voltage and transient voltage surges, the 824500851 can also help to suppress noise in high-speed data transmissions, thereby reducing the chance of errors in the data. This TVS diode is suitable for use in various automotive and communications applications, and is available in a variety of package sizes and configurations.
