TVS - Diodes

Transient-voltage-suppression (TVS) diodes are vital components for the protection of electronic and electrical equipment, especially those used in harsh environments. TVS-diodes are semiconductor devices specifically designed to protect against high voltages and currents caused by electrostatic discharges, inductive switching operations, lightning strikes and other power anomalies.

5KP43CA-TP is one kind of TVS-diode. Its application field covers consumer electronics, industrial control equipment, telecoms equipment, and so on. The 5KP43CA-TP is also used in automotive and aviation-related applications, and in medical devices.

The TVS-diode works by clamping voltage or current to a safe level when abnormal voltage or current conditions arise. When a voltage or current that exceeds the normal tolerance level is encountered, the TVS-diode instantly activates, redirecting the flow of current away from sensitive components and helping to protect them from a surge or voltage spike. TVS diodes also provide protection from high-frequency noise that may cause system malfunctions, such as from voltage transients induced by lightning or switching operations.

5KP43CA-TP TVS-diode typically employs large integrated ESD protection diodes. The device is composed of a single diode in a SOD-523 package and it is designed to limit the voltage encountered when subjected to ESD, lightning and inductive switching transients. The device is rated for +45V, ±23V, and +60V and offers low on-state resistance, providing superior diode performance.

The 5KP43CA-TP TVS-diode device offers industry-leading performance for suppressing transient voltage spikes, with a peak pulse power of 450W. It incorporates body-diode technology and patented high-temperature avalanche diode technology, providing optimal protection against ESD, EOS and other transients.

The 5KP43CA-TP TVS-diode’s working principle is that it uses a semiconductor junction to clamp the voltage or current to a specific safe level when high values of overvoltage or overcurrent are found. The device is designed in such a way that when an overvoltage situation occurs, the device conducts current, redirecting the current away from sensitive components and protecting it from surge or voltage spikes. Similarly, in the case of overcurrent, the device restricts the current flow to a safe level by triggering its avalanche breakdown mechanism.

The 5KP43CA-TP TVS-diode is designed for applications that require peak pulse power protection in a small package. Its low on-state resistance provides superior diode performance, allowing the device to protect sensitive electronic components from ESD, EOS, and other transient voltage surges. The device is widely used in consumer electronics, industrial control equipment, telecoms equipment, automotive and aviation-related applications, and medical devices.
