The TZQ5264B-GS18 is suitable for use in a variety of electronic equipment, including but not limited to industrial control and AC/DC adapters.

General Characteristics:

The TZQ5264B-GS18 is a single Zener diode with a voltage rating of 5.6-18V, thus suitable for providing a steady, reliable voltage in a wide range of applications. For example, the device can be used as a surge suppressor, reverse polarity protection, clamp, voltage reference, and EMI filter.The device has an operating temperature range of -65°C to 125°C and a forward voltage of 2V at 100mA. It also has a total capacitance of 7 pF, a reverse current of 150mA, and a power dissipation of 500mW.

Working Principle:

The TZQ5264B-GS18 is a Zener diode, which means it works on the principle of electric breakdown. When the applied voltage exceeds the breakdown voltage of the diode, the diode starts to conduct and dissipate the electric energy. As a result, the voltage across the diode is limited to the breakdown voltage, regardless of the applied voltage. This is useful in applications where a stable voltage is required, such as voltage regulation and EMI suppression.The TZQ5264B-GS18 also acts as a capacitive filter. As electric current passes through the diode, electric charge is accumulated and stored on the device’s capacitance. This capacitance serves as a filter; undesirable signals are reduced as they pass through the device.

Applications:

The TZQ5264B-GS18 is suitable for use in a variety of applications, including:

• Surge suppresors
• Reverse polarity protection
• Clamps
• Voltage references
• EMI filters
• Industrial control
• AC/DC adapters

Conclusion:

The TZQ5264B-GS18 is a single Zener diode from Tsinghua Unigraphics, useful in a variety of applications due to its wide operating voltage range, low capacitance, and high reverse current. It is suitable for use in applications such as surge suppression, reverse polarity protection, voltage referencing, and EMI filtering.
