Reverse Current (Ir): 10μA@6V

Under a reverse voltage of 6V, the reverse current of the ZM4738A is only 10μA. This extremely low reverse current value indicates that the ZM4738A conducts almost no current under reverse voltage, helping to reduce circuit power consumption and heat generation.

Impedance (Zzt): 4.5Ω

The impedance of the ZM4738A is 4.5Ω, enabling it to act as a good current limiter in the circuit. Through proper circuit design, the impedance characteristics of the ZM4738A can be utilized to limit the current size in the circuit, thereby protecting other components from damage due to excessive current.
