1N5229BTA

The 1N5229BTA is one of the types of zener diodes which are widely used in applications such as voltage regulation, clamping, rectification and signal-limiting. A zener diode operates in the breakdown region and relies on the Zener effect to govern the flow of current. Unlike a conventional diode, a zener diode has the ability to function in the reverse biased direction.

The 1N5229BTA is a single type of zener diode with a nominal Zener voltage of 7.5V and a maximum power dissipation of 200mW. It is made of glass passivated junction which ensures that the diode meets the most stringent requirements for surge and ESD immunity. The 1N5229BTA has a maximum working temperature of 85°C and an operating current range of -2.2mA to 0.93mA. It has a Zener impedance of 550 Ohms and a reverse leakage current of 5uA. The device comes in a DO-35 package and is available in various temperature grades.

The 1N5229BTA is generally used in applications where a low level of regulation is required. It can be used in voltage regulators circuits, A/D converters and other low noise control circuits where tight voltage regulation is needed. It is also used to clamp transients and for signal limiting applications. Additionally, the device can be used in polarity protection circuits, over-voltage protection circuits, voltage doubling circuits, current limiting circuits and in any other circuit where a reverse voltage needs to be regulated.

In operation, the 1N5229BTA works by allowing an increased current flow in the reverse biased region without the voltage increasing above the Zener voltage. For example, when the device is in its off state, the reversed biased voltage is above the breakdown voltage, so current is blocked. When the current reaches a certain level, the voltage drops and allows for current to flow. This process is known as the Zener effect. The breakdown voltage is determined by the type of material used in the diode and is generally constant over a certain temperature range.

At the same time, the 1N5229BTA has a voltage regulating property. This means that the device regulates the output voltage from the input voltage. The regulation process is based on the Zener voltage and the internal resistance of the diode. When the input voltage is lower than the Zener voltage, the device does not conduct. As the input voltage exceeds the Zener voltage, the diode conducts and regulates the output voltage at a constant level.

The 1N5229BTA is one of the most widely used zener diodes due to its simple and reliable operation. It is an ideal component for applications requiring a regulated source of power and is available in various temperature grades, making it suitable for a wide variety of uses. With its low leakage current and low operating temperature, the 1N5229BTA is a great choice for any application requiring reliable regulation of voltage.
