5KP75CA-HRA

TVS (transient protection diode) is an important device for circuit protection and reliability. The 5KP75CA-HRA is a type of TVS diode with exceptional performance and can protect a variety of circuits from over-voltage and transient events. 

The 5KP75CA-HRA has an operating voltage range of 5.8V to 75V and comes in the commercial and industrial grade. It features Glass-Passivated Junction for reliable operation, low Vf at surge currents and excellent clamping capability. The reverse leakage current is 100uA at 85V, making it perfectly suitable for high power DC-DC converters.

The 5KP75CA-HRA application field is mainly in automotive and industrial systems. Due to its reverse leakage current being low, it is beneficial in preventing reverse current flow in automotive, especially in DC-DC converters. It also works effectively in high power industrial systems such as HVAC systems where there is a need to protect from over-voltage as well as transient events. The manufacturer also offers a thermal shut-off feature that will disable the diode when the junction temperature rises above 150°C, which protects the system from any further damage.

The working principle of the 5KP75CA-HRA device is very simple. When an over-voltage or ESD transient event is detected, the diode is triggered and the current will be diverted to its drain and source terminal. The current is then redirected to the ground via an external resistor. This helps to suppress the voltage spikes and minimize the effect on the rest of the circuit.

The 5KP75CA-HRA is an excellent choice for most types of industrial and automotive applications. It has a wide operating voltage range and low leakage current, making it an ideal choice for protection against voltage variations and transient events. It is also equipped with a thermal shut-off feature, which helps to protect circuits from further damage when temperature rises above the set limit.
