SMBG4736E3/TR13

Diodes are two-terminal electrical components that can act as both a rectifier and an electrical switch. Zener diodes are special types of diodes that are designed to operate in reverse biased circumstances and hence the electrical current passes in reverse within the diode. A single zener diode is a diode that is capable of regulating the voltage over a single terminal. The SMBG4736E3/TR13 is an example of a single zener diode.

The SMBG4736E3/TR13 application fields include power supplies, transistors, and other semiconductor devices where a regulated voltage is required. The main difference of this kind of diode in comparison to the regular Zener diodes is its ability to provide an improved electromagnetic compatibility (EMC) which increases the safety in operation and prevents the potential interference or signal failure caused by the EMI. Due to the hermetic sealed package and encapsulated body, this diode is also capable of remaining stable in harsh environments such as industrial or military applications.

In terms of its working principle, this diode is based on the principle of the avalanche effect. When the voltage level of a Zener diode reaches a given value, the resistance of the diode starts decreasing and the current flowing through it increases. This continuous increase of the current flowing through the diode, results in an avalanche effect that is able to regulate the voltage level (avoiding spikes and other forms of fluctuations). The SMBG4736E3/TR13 has a relatively high value for the Zener voltage, meaning that it is capable of providing a relatively high level of voltage that is maintained over a single terminal.

In conclusion, the SMBG4736E3/TR13 is a single zener diode capable of providing a voltage regulation over a single terminal. This diode is mainly used in power supplies, transistors, and other semiconductor devices. In terms of its working principle, the diode is based on the principle of the avalanche effect, whereby the voltage level of the diode reaches a certain threshold that triggers an avalanche effect. This effect can then help maintain a regulated voltage in the circuit.
