The TPSMB2818CA from Littelfuse is an Automotive-Grade TVS Power Diode that is designed to protect sensitive electronic equipment from lightning and other transient voltage events. It has a breakdown voltage rating between 31.1-34.4 V and a maximum reverse leakage current of less than 1 µA. This AEC-Q101-qualified diode has a maximum clamping voltage of up to 42.5 V and has a power rating of 600 W. It has undergone whisker testing based on JESD201A’s specified procedures for reliable operation and follows ESD protection of data lines as per IEC 61000-4-2 standards. This UL-recognized TVS diode offers clamping capability with low incremental surge resistance to provide enhanced reliability. It is available in a surface-mount package that measures 4.570 x 3.940 mm and is ideal for the protection of I/O interfaces, VCC bus, on-board charging (OBC) driving circuits, traction inverters, and other battery-related vulnerable circuits used in automotive applications.
