The 5.0SMDJ24CA-Q is a bidirectional Transient Voltage Suppressor (TVS) diode designed for surge and overvoltage protection. It features a working peak reverse voltage of 24 V and a breakdown voltage between 26.7 V and 29.5 V. This device is rated for a peak pulse power of 5000 W and provides a maximum clamping voltage of 38.9 V at a peak pulse current of 129.0 A. As an AEC-Q101 compliant component in a surface-mount SMC (DO-214AB) package, it is well-suited for protecting power buses and I/O interfaces in automotive, industrial, and consumer electronics applications.
