The TP5KP48A is a thyristor-protected transient voltage suppressor (TVS) diode. It has a working voltage of 5KV and a peak pulse current of 48A. It is designed for use in high voltage transient protection circuits, and is used in a variety of applications, including power surge and load protection, lightning protection, transient and induced isolation, and surge current suppression.

The TP5KP48A is a low-power, nearly zero-operating voltage, bidirectional protection component. It consists of a thyristor and a PN-junction diode, both of which are connected in parallel. The thyristor serves as the main switch to regulate the flow of current, while the PN junction diode serves as a current-limiting device. When a sudden surge of voltage is detected, the thyristor will act as a switch by conducting current in both directions. The PN junction diode will then start to conduct current from the lower voltage side and limit the surge current.

The TP5KP48A is available in both surface mount and through-hole packages. The surface mount package is offered in a standard DIP 8-pin or SOIC8 packages. It is designed for use in a wide variety of applications, including industrial automation, automotive, and consumer electronics. One key feature of the TP5KP48A is its low capacitance, which provides excellent transient protection performance. It has a low capacitive noise figure of 8pF (QC=2.9pF, DC=5.1pF) and a response time of less than 1nS. This ensures that the diode will effectively suppress long-duration transients with fast response times.

The TP5KP48A also provides a wide operating temperature range. It can handle temperatures from -55°C to 125°C. This ensures that it will continue to provide protection in a variety of applications, even when exposed to extreme environmental conditions. The TP5KP48A is designed for use in circuits that require reliable high-voltage transient protection. It is a bi-directional protection component that provides excellent performance in suppressing long-duration transients. Its low capacitance ensures fast response times and its wide temperature range makes it suitable for use in a wide variety of applications.
