The MMSZ5251B-7-F is a 22V Zener diode from Diodes Incorporated, designed for general purpose voltage regulation and clamping. It offers a power dissipation of 500mW at lead temperature +75°C and 370mW at ambient +25°C, with a junction-to-ambient thermal resistance of 338°C/W. The device features a maximum reverse leakage current of 100nA at 17V and a typical forward voltage of 900mV at 10mA. The Zener impedance is 29Ω at the specified test current. This diode is housed in a surface mount SOD-123 package, with a cathode band polarity marking. The package is molded plastic with UL 94V-0 flammability rating and is halogen-free, lead-free, and RoHS compliant. It is suitable for automated assembly processes and is available in tape and reel packaging of 3000 pieces. The operating temperature range is -65°C to +150°C. This component is commonly used in voltage reference applications, power supply regulation, and protection circuits.
