SOD-80 0.5W 2.4-75V Zener Diode ZMM5221B Thru ZMM5267B Tape in reel
SMD Zener diodes are widely used as voltage references and as shunt regulators to regulate the
voltage across small circuits. When connected in parallel with a variable voltage source so that it
is reverse biased, a SMD Zener diode conducts when the voltage reaches the diode's reverse
breakdown voltage. From that point on, the low impedance of the diode keeps the voltage across
the diode at that value.
Features
1. High reliability
2. Very sharp reverse characteristic
3. Low reverse current level
4. VZ-tolerance±5%
