1SMB5944 R5G

Diodes - Zener - Single

1SMB5944 R5G is a single Zener Diode. It is a semiconductor device that is used to control current flow in one direction while allowing current flow in the opposite direction. The diode\'s junction is made up of two types of material: an N-type semiconductor and a P-type semiconductor. This junction allows current flow from the P-type to the N-type semiconductor. When the material is reversed, current flow stops.

A zener diode is a special type of diode that is used as a voltage reference. When the zener diode is reverse biased, it operates in a region called the zener region. In this region, the diode pinches off and requires a very small voltage difference to begin conducting current. The voltage at which it begins to conduct is known as the zener voltage. The zener diode will remain in conduction until the reverse voltage across it is larger than the zener voltage. Zener diodes are commonly used to regulate voltage in a circuit.

The 1SMB5944 R5G has a nominal zener voltage of 5.0 volts with a maximum voltage of 5.4 volts. It is rated for up to 400 mW power dissipation with a maximum surge current of 150mA. The forward current at a = 200mA is approximately 0.7V. The 1SMB5944 R5G has a breakdown voltage of 5.4V at an operating temperature between -65 and +175 degrees Celsius. The diode features an operating capacitance of 0.1pF, a reverse recovery time of 0.7ns, a leakage current at a reverse voltage of 5.4V of 15μA, and a breakdown voltage temperature coefficient of -2.3mV/°C.

1SMB5944 R5G diodes are used in a variety of applications such as power supplies, low power DC-DC converters, voltage regulation, and spike suppression. Zener diodes are also often used to protect electrical devices from damage due to voltage fluctuations caused by ambient temperature, power supply fluctuations, or other factors. In addition, they can be used as input and output protection devices in digital circuits or as temperature sensing protection devices in an LED system.

In conclusion, the 1SMB5944 R5G is a single Zener Diode that can be used for a variety of applications. It has a relatively low breakdown voltage, low capacitance, and fast reverse recovery time, making it a suitable choice for voltage regulation and protection applications. The diode can also be used in power supplies, DC-DC converters, and LED systems.
