MM3Z51VB Description

Short technical summary and product information.

The MM3Z51VB is a 51V Zener diode designed for voltage regulation and protection in low-power circuits. It features a nominal zener voltage of 51V with a tight ±2% tolerance. Power dissipation is rated at 200mW maximum. The device offers low reverse leakage current of 45nA at a reverse voltage of 35.7V, and a maximum forward voltage of 1V at 10mA. The maximum zener impedance is 169Ω at a test current of 5mA.

 

This Zener diode is housed in a compact SC-90 / SOD-323F surface mount package, making it suitable for space-constrained applications. The operating temperature range spans -65°C to 150°C, allowing use in extreme environments. Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in portable electronics, power supplies, and analog circuits.
