SZMMBZ5226BLT1G Description

Short technical summary and product information.

The SZMMBZ5226BLT1G is a Zener voltage regulator diode from On Semiconductor, part of the MMBZ52xxBLT1G series with automotive qualification (AEC-Q101). It offers a nominal Zener voltage of 3.3V with ±5% tolerance and a maximum power dissipation of 225mW on FR-5 board. The device features a low forward voltage of 900mV at 10mA and a maximum impedance of 28Ω at Zzt. Reverse leakage current is limited to 25µA at 1V. Designed for surface mount assembly, it comes in a compact SOT-23-3 package, ideal for high-density PCB applications. The diode is ESD rated Class 3 (>16kV) per Human Body Model, ensuring robust protection. It is Pb-free, halogen free/BFR free, and RoHS compliant, suitable for environmentally conscious designs. The operating temperature range spans -65°C to 150°C, with thermal resistance of 556°C/W on FR-5 and 417°C/W on alumina substrate.
