The TPSMB1505CA from Littelfuse is an AEC-Q101-Qualified Asymmetric TVS Diode that has been designed to protect automotive SiC MOSFET gate driver from overvoltage events. It has a breakdown voltage of 18.5 V and a maximum reverse leakage current of 1 µA. This AEC-Q101-qualified diode has a maximum clamping voltage of up to 24.6 V. It is designed to offer excellent clamping capability with low incremental surge resistance. This power diode undergoes rigorous whisker testing based on JEDEC JESD201A standards and follows ESD protection of data lines by IEC 61000-4-2 standards. It is built with a glass-passivated chip junction for high-reliability automotive applications. This RoHS-compliant power diode is available in a surface-mount package that measures 4.570 x 3.940 mm and is ideal for gate driver protection of SiC MOSFETs, onboard chargers (OBC), and traction inverter applications.
