Zener diodes, like any other diode, contain two junctions — the anode (A) and the cathode (K) — joined together to form a single semiconductor device. Generally, the anode is positively charged and the cathode is negatively charged. In a Zener diode, the anode and cathode are not the same. Instead, a Zener diode has an anode and a Zener (or reverse bias) junction.

The SZMM3Z36VT1G is one of many Zener diodes available on the market, with a breakdown voltage of 33 volts and a power rating of 1W. It is designed for a range of applications, from powering devices such as laptops and smartphones, to providing protection against voltage spikes and surges.

The SZMM3Z36VT1G works on a simple principle. When the voltage across the diode reaches the breakdown voltage (33 volts), the reverse bias begins to conduct current, creating a Zener effect. This Zener effect will continue as long as the voltages remain within the breakdown range.

In a typical application, the SZMM3Z36VT1G is connected in series with a power supply, with the anode connected to the positive supply, and the cathode connected to the negative (ground) supply. When a voltage spike occurs, the current in the circuit is diverted to the negative terminal, preventing damaging voltage surges from reaching the device or component being powered or protected.

Another application of the SZMM3Z36VT1G is as a voltage regulator. In this application, the diode is connected in series with a low-impedance load, with the anode connected to the load, and the cathode connected to the positive power supply. When the voltage across the diode reaches the breakdown voltage, the voltage regulator kicks in, keeping the voltage across the load constant, regardless of the input voltage.

Finally, the SZMM3Z36VT1G can also be used as a voltage reference. In this application, the diode is connected in series with a high-impedance load, with the anode connected to the load, and the cathode connected to the positive power supply. The voltage across the diode will remain constant as long as the voltage at the positive supply remains within the breakdown range. This constant voltage can be used to reference other voltages in the circuit, allowing for easy voltage setting and control.

In summary, the SZMM3Z36VT1G is a Zener diode with a breakdown voltage of 33 volts and a power rating of 1W. It can be used in a variety of applications, including voltage regulation, voltage reference, and protection against voltage spikes. The principle of operation is simple: when the voltage across the diode reaches the breakdown voltage, the current in the circuit is diverted to the negative terminal, preventing damaging voltage surges from reaching the device or component being powered or protected.
