Key Parameters:

VZTyp (Typical Zener Voltage): The typical zener voltage, VZTyp, for the MM5Z12V is specified as 12V. This parameter represents the expected voltage at which the zener diode begins conducting and provides a relatively constant voltage output.

VZ Range: The allowable zener voltage range for the MM5Z12V is specified as 11.4V to 12.7V. This range accounts for manufacturing tolerances and operating conditions, ensuring that the zener diode's actual voltage characteristics fall within this specified range.

Maximum Power Dissipation (PD): The maximum power dissipation specification of 200mW denotes the highest amount of power that the zener diode can handle without sustaining damage. This parameter is critical for determining the diode's thermal stability and safe operating limits in practical circuits.

Reverse Current (Ir) at 9V: The reverse current specification of 100nA at 9V indicates the small amount of current that flows through the diode in the reverse direction when a reverse bias voltage of 9V is applied. This low reverse current is integral for applications requiring minimal leakage current and high precision.

Dynamic Impedance (Zzt): The dynamic impedance of 25Ω represents the small-signal impedance of the zener diode when it is conducting. This parameter is essential for understanding the diode's behavior under varying AC or small-signal conditions, providing insights into its performance in dynamic circuits.
