3.0 Watt Surface Mount Silicon Zener Diode 3SMBJ5918B Thru
3SMBJ5956B With SMB Case
The Zener diodes are primarily used as voltage regulator devices
providing a reference voltage
for voltage regulators or to protect other semiconductor devices
from momentary voltage pulses.
These devices are specific type diodes designed to be operated in
the reverse breakdown region.
It allows current to flow in the forward direction in the same
manner as an ideal diode, but will also
permit it to flow in the reverse direction when the voltage is
above a certain value known as the
breakdown voltage, "zener knee voltage" or "zener voltage".
