BZT52H-C18,115

Zener diodes are a type of diode designed to allow current to flow in the forward direction in the same manner as an ideal diode. However, it can also permit a small amount of reverse current (without greatly exceeding the rated reverse voltage of the diode) when the voltage across it exceeds the rated reverse voltage. This property can be used to stabilize a voltage under varying load and temperature conditions. The BZT52H-C18,115 is a silicon planar power Zener diode with a reverse voltage of 65 volts and a maximum power dissipation of 100mW.

Application field and working principle

BZT52H-C18,115 Zener diodes are best suited for low-power applications in which the circuit\'s input and output levels need to be precisely aligned. These diodes can be used as voltage clampers or shunts, or can be placed in series with a resistor to maintain a stable output voltage. These diodes are also often used in DC power regulation circuits due to their ability to regulate a output voltage within specific parameters.

When the voltage across the diode is less than the reverse breakdown voltage, the diode behaves like an ideal diode, operating in the forward-biased state and allowing current to flow in the forward direction. When the voltage across the diode exceeds the breakdown voltage, the excess current passes through the Zener diode in the reverse direction. This is referred to as the Zener effect and is the principle by which Zener diodes regulate voltage.

The BZT52H-C18,115 has a breakdown voltage of 65 volts and a maximum power dissipation of 100mW. Its maximum allowable power dissipation should not be exceeded in order to avoid overheating and damage to the diode. Its reverse leakage current ranges from 1uA to 10mA, or the current that the diode draws from its source when its reverse voltage is applied. It has a capacitance of 5pF and a maximum reverse surge current of 100mA.

Due to its low-power, high-voltage capabilities, the BZT52H-C18,115 is used in a wide variety of applications. These include DC power regulation, voltage reference, voltage clamping, and voltage shunt applications. It is also used in general-purpose circuits, such as logic gates and amplifiers, that require a precise voltage level. These diodes are also used in a variety of consumer electronics, such as voltage regulators, voltage converters, and motor drivers.

In conclusion, BZT52H-C18,115 Zener diodes are designed to stabilize a voltage under varying load and temperature conditions, making them ideal for applications that require precise voltage regulation. These diodes are also capable of operating at high voltages with low power dissipation, making them well-suited for a variety of low-power applications. They are used in a variety of consumer electronics and are also used in general-purpose circuits for logic gates and amplifiers that require a precise voltage level.
