MMSZ5231B-7-F zener voltage regulator diode
The MMSZ5231B-7-F, a surface-mount zener voltage regulator diode from Diodes Incorporated, is housed in a compact SOD-123 package, engineered to provide precise voltage regulation, voltage clamping and transient suppression in a wide range of low-power circuits such as power management, signal conditioning and protection applications. This zener diode features a nominal zener voltage (Vz) of 5.1V with a tight tolerance of ±5%, a maximum zener impedance (Zzt) of 10Ω at Izt = 20mA, and a maximum reverse leakage current of 5µA at Vr = 1V, ensuring stable regulation characteristics under varying load conditions. Its key electrical specifications include a continuous power dissipation of 500mW at an ambient temperature of 25°C, a low thermal resistance of 350°C/W junction-to-ambient that allows effective heat dissipation, and a typical voltage temperature coefficient of +5 mV/°C that provides relatively stable performance across temperature variations. The device is designed for general-purpose voltage regulation, offering a sharp breakdown characteristic and low dynamic impedance, making it suitable for precision voltage reference, overvoltage protection and clipping circuits in portable electronics. It is widely deployed in voltage regulator feedback loops, microcontroller I/O protection, battery-powered devices, sensor interfaces and consumer electronics where space-efficient, reliable voltage regulation and transient suppression are required.
