概述
Description
P6SMB30CA is a high‑power transient-voltage-suppressor (TVS) diode in the SMB package (DO-214AB), part of the P6SMB family. It protects circuits from voltage transients on power and signal lines (surges, load dumps, ESD). The “30” denotes a ~30 V rating (standoff voltage), and the device handles about 600 W peak pulse power (10/1000 µs). It’s a surface-mount component suitable for board-level surge protection in automotive, telecom, and industrial applications. The “CA” suffix indicates a specific variant; exact polarity and electrical specs (V_R, V_C, I_PP) are defined in the datasheet and should be consulted for precise use.
