ZMY4V7-GS18 Discrete Semiconductor Products

ZMY4V7-GS18 is a type of single Zener diode, a diode which incorporates the special property of electrical breakdown, referred to as Zener breakdown. A Zener diode has a unique voltage-current characteristic, the diode is reverse biased, but behaves like a voltage regulator when reverse voltage is above the Zener breakdown voltage, regulating the reversed current and maintaining a constant voltage at the anode.The ZMY4V7-GS18 is built with a glasspassivated junction and has a maximum reverse leakage current of 5 microamps when operating at 7.5 volts. It has a maximum peak power rating of 500 mW and is usually used in voltage-regulation circuits.In general, the working principle of a Zener diode can be summarized by its voltage-current characteristic. It looks like a diode in forward bias. That is, when a positive level of voltage is applied to the Zener diode, the current starts flowing through the diode, controlling the voltage drop across it, and the current gradually increases as the voltage increases. At some point, the breakdown voltage is attained when the reverse voltage is applied and the Zener diode starts to work as a voltage regulator.The principle of the application field of the ZMY4V7-GS18 can be further summarized as it provides a stabilized power supply to electronic circuits which require a certain fixed voltage and current. It also applies to circuits which require transient voltage suppression, which is when the voltage is responsible for a maximum current that is safe for other components in the circuit.In order to provide the stabilized power supply, the ZMY4V7-GS18 is generally connected in series with the circuit, with its cathode attached to the positive line of the circuit, and its anode (which is the regulated output) connected to the negative line. The current passing through the diode then begins to flow through the circuit, and eventually reaches the regulated voltage.Finally, the ZMY4V7-GS18 can also be used in protection circuits to protect a circuit from over-voltage transients, by limiting the voltage to a safe level, and also in voltage reduction circuits, where it is used to convert high input voltages to low output voltages.In conclusion, the ZMY4V7-GS18 is a single Zener diode which has a specific application field and working principle. It can be used to provide a stabilized power supply to electronic circuits, and to protect them from over-voltage transients or to convert high input voltages to low output voltages. It is built with a glasspassivated junction and has a maximum reverse leakage current of 5 microamps when operating at 7.5 volts, with a maximum peak power rating of 500 mW.
