SMBJ5369C/TR13 Equivalent & Substitute Zener Diode Parts Reference

Part Overview

The Microchip Technology SMBJ5369C/TR13 is a surface-mount Zener diode categorized under Diodes, Zener. Key parameters include a Zener voltage of 51 V, maximum power dissipation of 5 W, ±2% voltage tolerance, and an SMBJ (DO-214AA) package. The product is active and available in tape & reel (TR) packaging.

Finding alternative models is necessary due to considerations such as RoHS non-compliance of the SMBJ5369C/TR13, supply chain management, or requirements for differing tolerances, power ratings, and compliance statuses. Substitution ensures flexibility in manufacturing and maintenance when the original part is unavailable or does not meet compliance requirements.
