SMBJ5929C/TR13 Zener Diode Equivalent & Substitute Parts Reference

Part Overview

SMBJ5929C/TR13 is a Zener diode manufactured by Microchip Technology, category Diodes, Zener, offered in a surface-mount DO-214AA (SMBJ) package. It features a nominal Zener voltage of 15 V, a maximum power dissipation of 2 W, and a tight tolerance of ±2%. The diode offers high reliability with a wide operating temperature range of -65°C to 150°C. The product is active and is available as tape & reel packaging for automated assembly. Alternative models are necessary when specific inventory, compliance (such as RoHS or MSL status), or higher power ratings are required for engineering and logistics purposes.
