MMBZ5229BLT1G Description

Short technical summary and product information.

The MMBZ5229BLT1G is a Zener voltage regulator diode from On Semiconductor, offering a nominal Zener voltage of 4.3V with ±5% tolerance. It is rated for 225mW power dissipation on FR-5 boards and 300mW on alumina substrates, making it suitable for low-power voltage regulation applications.

 

Key electrical specifications include a maximum impedance (Zzt) of 22Ω, reverse leakage current of 5µA at 1V, and forward voltage of 900mV at 10mA. The device also features an ESD rating of Class 3 (>16kV) per Human Body Model, enhancing robustness in portable electronics.

 

The diode is housed in a surface mount SOT-23-3 (TO-236-3, SC-59) package, supplied in tape and reel packaging with 3000 units per reel. It operates over a junction temperature range of -65°C to 150°C. The component is RoHS compliant, Pb-free, and halogen free, meeting modern environmental standards.
