Radio CompanyThe LMSZ5248BT1G is a RoHS (Restriction of Hazardous Substances) compliant SMD Zener diode housed in a SOD-123 package and manufactured by the Leshan Radio Company. It has a power dissipation of 300mW and maintains a 5.2V Zener voltage with a maximum Zener impedance of 4.5 O. It is characterized by its low noise, low leakage current, stable performance and high thermal shock endurance. The temperature range for application is -65 to +175°C. It is designed to be used for Zener voltage regulation, transient protection, and current limiting. It has very good surge strength, and is regularly used in automotive, military, and consumer electronics applications.
