TVS (transient voltage suppressors) diodes are an increasingly important component in a wide range of electronic circuits. In many of these circuits, their primary role is to provide protection from voltage spikes and electrical surges that could cause permanent damage to the circuit components or degrade its performance. The 5KP43A-B TVS diodes provide this essential protection in a wide range of electronic circuits, making them ideal for a range of applications.

The 5KP43A-B family of TVS diodes is designed to protect against electrical transients, which typically range from a few volts up to several thousand volts. The peak pulse current rating of these devices is up to 6.5A and the breakover voltage ratings range from 6.8V to 26V. The clamping voltage ratings range from 17V to 35V. The surge capability of the 5KP43A-B devices is 4kA at 8/20us waveforms.

These devices provide line-to-line protection for three-phase AC power supplies, providing protection for components such as motors, transformers and power supplies from damaging transients. The 5KP43A-B devices are also suitable for protecting single and multiple circuit boards against EMC interference sources. These sources can include electrostatic discharges, radio-frequency interference (RFI) and other transient spikes.

The working principle of the 5KP43A-B TVS diodes is based on the Avalance breakdown effect. When subjected to a voltage above the device\'s breakover voltage rating, the TVS diode will begin to conduct. This allows the current to pass through the diode, and the excess voltage and energy to dissipate, thus providing the protection. As the current continues to rise, the diode\'s internal temperature increases, resulting in a temperature-dependent reduction in the diode\'s clamping voltage. The internal structure of the 5KP43A-B devices helps to limit the shielding effect of the breakdown voltage and to limit the temperature of the diode during operation.

The 5KP43A-B devices are available in both surface mount and through hole packages. The devices are suitable for use in a wide range of operating temperatures, ranging from -55°C to 125°C. The devices offer a low-resistance profile which allows them to dissipate high levels of energy without overheating.

The 5KP43A-B devices provide reliable protection from electrical transients and EMC interference sources. Their wide operating temperature range and low-resistance profiles make them suitable for a wide range of applications, including automotive, medical, industrial and military.
