7V Clamp 24A (8/20µs) Ipp Tvs Diode Surface Mount SOT-143

CD143A-SR70 Information

Description

Here's a concise introduction to the CD143A-SR70: The CD143A-SR70 is a unidirectional, four-element silicon transient voltage surge (TVS) diode product from Bourns. It features a TO-253-4 or TO-253AA package configuration, making it suitable for use in various electronic devices. As a TVS diode, its primary function is to protect sensitive components from voltage spikes and electromagnetic interference (EMI). The device's unidirectional design allows it to dissipate energy in one direction only, providing effective surge protection without creating unnecessary backflow of current. With its ability to withstand high-temperature and voltage stresses, the CD143A-SR70 is a reliable component for a wide range of applications, including consumer electronics, automotive systems, and industrial equipment.

Package

According to the product information, the package type of CD143A-SR70 is TO-253-4 or TO-253AA, which are both types of land-and-lead packages used for surface-mount devices.

Pinout

The CD143A-SR70 is a Unidirectional TVS Diode from Bourns, with a TO-253-4 or TO-253AA package.

Pin count: 4 pins

Functions:

  • Pin 1: Anode (positive)
