SZMMBZ5229BLT1G Description

Short technical summary and product information.

The SZMMBZ5229BLT1G is a Zener voltage regulator diode from On Semiconductor, part of the MMBZ52xxBLT1G series. It offers a nominal Zener voltage of 4.3V with a tolerance of ±5% and a maximum power dissipation of 225mW on FR-5 board. The device features a forward voltage of 900mV at 10mA, reverse leakage current of 5µA at 1V, and a maximum Zener impedance of 22Ω. It is designed for surface mount assembly in the compact SOT-23-3 package (TO-236).

 

The part operates over a junction temperature range of -65°C to 150°C and has a thermal resistance of 556°C/W (junction-to-ambient on FR-5 board). It is rated for ESD protection over 16kV (Class 3, Human Body Model) and meets UL 94 V-0 flammability rating. The SZ prefix indicates automotive qualification (AEC-Q101) and PPAP capability.

 

The component is Pb-Free, Halogen Free/BFR Free, and RoHS3 compliant. It is supplied in tape and reel packaging with 3,000 pieces per reel. Typical applications include voltage regulation in cellular phones, handheld portables, and high-density PC boards where space is critical.
