Additional Details

The MTZJ2.2A has a nominal Zener voltage of 2.2V. Zener voltage tolerance is typically +/-5%. It is commonly available in a small surface mount package such as SOD-323. Power dissipation is typically 500mW. The operating temperature range is typically -55°C to +150°C. It is constructed using a silicon PN junction designed to operate in the reverse breakdown region. When the reverse voltage across the diode exceeds the Zener voltage, the diode conducts, maintaining a nearly constant voltage across its terminals. The surge current rating specifies the maximum current the diode can withstand during a transient overvoltage event. Care should be taken not to exceed the maximum power dissipation of the diode to prevent overheating and damage.
