P4KA33HE3/73

TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are widely used in many electronic devices today. They are used to protect sensitive components, such as microcontrollers, memories, logic gates, and other integrated circuits, from surging voltages and other anomalies. TVS diodes have a wide range of applications, ranging from consumer electronics to industrial and automotive applications. The P4KA33HE3/73 is one such device.

P4KA33HE3/73 Application Field and Working Principle

The P4KA33HE3/73 is a unidirectional TVS diode that offers an excellent combination of low capacitance, ultra-low leakage, and small package size, as well as low typical junction capacitance of 1.6 pF. It is designed to protect voltage sensitive components such as batteries, USB ports, and other high speed circuits from electrical transients due to electrostatic discharge (ESD). Moreover, the device offers a high surge current tolerance that can withstand up to 150A of 8/20 microseconds lightning discharge currents, and is available in an industry standard SOT23-5 package.

The P4KA33HE3/73 diode is designed to protect against transients and provides excellent clamping and ESD protection. It works by sensing the voltage across its terminals and quickly turning it on when it exceeds a certain threshold, effectively clamping the voltage. In addition, it features a low leakage current and very low capacitance, which enable it to provide fast response times while still having minimal effects on signal integrity.

The P4KA33HE3/73 is ideal for use in a variety of applications such as industrial and automotive electronics, high speed USB ports and data lines, LCD TVs, smartphones, and tablets. Additionally, the device provides excellent EMI/RFI protection, and is RoHS compliant.
