The TP5KP45A is a TVS (Transient Voltage Suppressor) diode, designed to protect sensitive circuits from temporary over-voltage transients such as electrostatic discharge (ESD) and power disturbances. The TP5KP45A is a suppressor specifically developed for application in the ESD protection of data communication, automotive, and consumer electronic equipment. It is designed to clamp transients at low voltage without disturbing the normal operation of the monitored circuit.

The TP5KP45A transient protection diode features a low clamping voltage of 5.1 V and a low leakage current of 10 µA at 5 V. This fast-response device can clamp transients in less than 1 ns, and its reverse protection can prevent damages associated with ESD or electro-magnetic interference (EMI) up to 25 kV. It is available in a small SOD-323F package with 4 pins. The device is compliant with RoHS, and it has an operating temperature range of -55 ºC to +175 ºC.

The TP5KP45A TVS diode works through a diode-like process. The fast-reacting device has a gap of around 5 V when the voltage applied to its anode is low, and it will block any negative or positive potentials. When a transient goes beyond the breakdown voltage, current will flow across the gap, and the device will regulate the voltage of the active circuit back to a safe level. This process is uniformly operational in both positive and negative polarities.

The TP5KP45A TVS diode is suitable for applications in which over-voltage protection is necessary. Its low profile and low capacitance make it ideal for protecting any electronic circuit from sudden over-voltage transients. Its low leakage current makes it suitable for ESD protection in data lines, and its fast response allows it to protect from downtime associated with ESD failures.

The TP5KP45A TVS diode has a wide range of applications, including mobile phones, data lines, automotive, home automation, and consumer electronic equipment. This device is especially suitable for applications where a low-profile protectors are needed. With its fast response and low-clamping voltage, the TP5KP45A can be used to protect a wide range of circuits, including microcontrollers, buses, and power converters.
