TVS-Diodes are a type of semiconductor device that offers protection from accidental electrostatic discharges (ESD). The 5KP51A-HR is a unidirectional over-voltage protector diode particularly suited for Automotive, Consumer electronics and Industrial applications. It is specially designed to protect voltage sensitive components against transient voltage spikes.

The 5KP51A-HR is a low-capacity TVS diode that offers enhanced ESD protection than traditional TVS diodes. It provides unidirectional ESD protection up to 4kV (HBM), while the repetitive peak pulse power capacity rating for the device is WH H-700mW. It is also equipped with protection against the highest rated discharge current at 8A (8/20μs).

The 5KP51A-HR ensures fast transient response time with a peak pulse current of Ipp=80A (8/20μs) at operating junction temperature of -55 degrees to 125 degrees Celsius. The device is designed to be exposed to potentially harmful voltages without damage, and has a transient voltage clamping capability of 28V peak.

The 5KP51A-HR is specifically designed for Automotive, Consumer electronics and Industrial applications. It can be used in cars, trucks, SUVs, motorcycles, ATVs, and RV\'s for voltage derating, fault protection, and ESD protection. It is particularly suited for line protection and LAN interface applications in consumer electronics, as well as for surge protection in industrial applications.

The 5KP51A-HR works on the principle of fail-safe snapback. This means that when an electrostatic discharge (ESD) or electrical surge causes the input voltage to exceed its safe operating limits, the TVS diode diverts the electrical current to a safe path. It redirects this excess voltage until the voltage returns to its normal operating level.

The 5KP51A-HR, being a unidirectional TVS diode, can be used to protect internal devices from external surges or ESDs which could cause damage or disruption of optical, electrical and digital signals. It is suitable for both linear and switching power supply protection, and has a wide operating temperature range of -55 degrees Celsius to 125 degrees Celsius.

The 5KP51A-HR is a popular device for providing reliable and effective protection from electrostatic discharges, transients, and surges. It is a robust device with an operational life time extension in the event of excess voltage or ESD, making it the perfect choice for Automotive, Consumer electronics and Industrial applications.
