SZMMBZ5252ELT1G Description

Short technical summary and product information.

The SZMMBZ5252ELT1G is a Zener voltage regulator diode from On Semiconductor designed for voltage regulation in space-constrained applications. It provides a nominal Zener voltage of 24V with a tolerance of ±5%. The device offers a maximum power dissipation of 225mW on FR-4 or FR-5 board at 25°C ambient temperature, and up to 300mW on an alumina substrate.

Key electrical characteristics include a maximum Zener impedance of 33 Ω, a typical forward voltage of 900mV at 10mA, and a maximum reverse leakage current of 100nA at 18V. The diode is rated for an operating temperature range of -55°C to 150°C and a storage temperature range of -65°C to 150°C.

The device is housed in a surface-mount SOT-23-3 (TO-236) package and is supplied in tape and reel packaging with a standard quantity of 3000 pieces. It features an ESD rating of Class 3 (>16 kV) per the Human Body Model and is Pb-free (RoHS3 compliant verified per datasheet). The package is designed for automated board assembly and is suited for high-density PCBs.
