TZM5231B-GS18

The TZM5231B-GS18 Zener diode is a single, low-power device designed to regulate voltage in circuits that require a steady voltage output. It is used in applications where the input voltage may vary significantly, and the output must be kept steady. The TZM5231B-GS18 has a variety of applications in low-voltage circuit designs, including power supplies and voltage regulators.

Device Characteristics

The TZM5231B-GS18 is a low-power Zener diode with a Power Dissipation rating of 1/4 Watt (mW). It has a maximum Reverse Current of 2.0mA, a Maximum Voltage rating of 18V, and a Maximum Reverse Voltage of 5V. The package is a SOT-323, which is a small surface mount package. Other characteristics of the TZM5231B-GS18 include an Operating Temperature range of -65oC to +200oC and a Storage Temperature range of -65oC to +150oC.

Working Principle

A Zener diode works by taking advantage of the properties of diodes, which conduct current in one direction and block it in the other. When a reverse voltage is applied to the diode, it will allow current to flow in the opposite direction compared to normal current. This property is called a “Zener breakdown” and it is what allows the TZM5231B-GS18 to regulate voltage. The Zener diode works by allowing current to flow in the opposite direction when the input voltage is greater than the Zener breakdown voltage. This will drop the voltage across the diode to the Zener voltage, setting the voltage output.

Example Applications

The primary application for the TZM5231B-GS18 diode is in low-voltage circuit designs. It can be used in power supplies to regulate the output voltage, which is useful in applications where the input voltage may vary due to fluctuations or other environmental factors. The TZM5231B-GS18 can also be used in voltage regulators, which are used to regulate the amount of current or voltage in a circuit. Another application is in over-voltage protection circuits, where the TZM5231B-GS18 can be used to help keep voltage levels in check.

Conclusion

The TZM5231B-GS18 Zener diode is a low-power device designed to regulate voltage in low-voltage circuit designs. It has a variety of applications, including in power supplies, voltage regulators and over-voltage protection circuits. Because of its low-power rating, the TZM5231B-GS18 is ideal for applications where the input voltage may vary and the output voltage must be kept steady.
