Substitute Part Grouping Explanation

Substitute devices for SMBJ5381C/TR13 are selected solely according to the following strictly matched parameters: Zener voltage (130 V), package (DO-214AA, SMB), mounting type (Surface Mount), and diode category (Zener Diode). Other tabulated values that influence interchangeability include maximum power dissipation, tolerance, maximum impedance, reverse leakage current, forward voltage, operating temperature range, RoHS/REACH compliance, and Moisture Sensitivity Level. Substitution does not consider any unlisted or inferred attributes.
