The MMBZ5249B is a 19V Zener diode designed for voltage regulation and protection applications. It features a nominal zener voltage of 19V with a tolerance of ±5%, ensuring precise voltage clamping. The diode can dissipate up to 350mW of power, making it suitable for low-power circuits. It has a maximum forward voltage of 900mV at 10mA and a reverse leakage current of 100nA at 14V. The device is offered in a compact SOT-23-3 surface-mount package, which is ideal for space-constrained designs. The operating temperature range spans from -55°C to 150°C, allowing use in harsh environments. Typical applications include voltage regulation, overvoltage protection, and reference voltage generation in consumer, industrial, and automotive electronics.
