Features of Zener Diode MM3Z27

The MM3Z27 zener diode is configured independently, allowing it to be used singularly in circuits without the need for complex networks with other components. Its nominal voltage regulation value is 27V, meaning under normal operating conditions, it stabilizes the circuit voltage around 27V. Moreover, the regulation range extends from 25.1V to 28.9V, providing circuit designers with greater flexibility and tolerance.

In addition to stable voltage output, MM3Z27 boasts excellent power handling capabilities, with a power rating of up to 300mW. This enables it to withstand substantial currents and voltage fluctuations without damage, making it widely applicable in circuits requiring stable high currents and voltages.

Regarding reverse voltage, MM3Z27 performs exceptionally well. With a reverse voltage of 21V, its reverse current is only 100nA, effectively reducing power consumption and heat accumulation in the circuit, thus enhancing stability and reliability.

Furthermore, MM3Z27 has an impedance (Zzt) of 70Ω, placing it in a moderate range suitable for electronic circuits. It prevents excessive currents while ensuring the diode effectively performs its voltage regulation function under normal operating conditions.
