RLZTE-1139B Application Field and Working Principle

RLZTE-1139B is a single Zener diode that is used for many general applications. It is very popular with hobbyists and electronics engineers for its reliability, low cost, and unique features. This article will explain the application field, working principle, and advantages of the RLZTE-1139B.

Application Field

The RLZTE-1139B has many applications in various electronic devices. It is commonly used as a voltage regulator in consumer electronic devices, radios and televisions, medical equipment, and other industrial and automotive applications. It is also used in DC circuits to limit current and protect against excessive voltage surges. Additionally, the RLZTE-1139B is often employed in reverse polarity protection and voltage clamping.

Working Principle

The RLZTE-1139B is a Zener diode, meaning it has two distinct states of conductivity. At the forward biasing voltage, which is the current it sees when connected to a voltage source, the diode allows current to flow in a single direction. When the reverse bias voltage surpasses the Zener Voltage of the diode, it switches to its reverse conduction region and allows current to flow in both directions. This process is known as Zener breakdown and happens due to the silicon being able to create electron avalanche, a phenomenon where excess electrons in the junction create additional current.

The Zener Voltage is the most important factor in an RLZTE-1139B diode because it determines the voltage that can be applied to it. The higher the Zener Voltage, the higher voltage the diode can withstand before it reaches its reverse conduction region. A higher Zener Voltage ensures the diode will last longer and be more reliable.

Advantages

The RLZTE-1139B is one of the most reliable and robust Zener diodes available on the market. Its zener voltage is low, which ensures it is able to provide stable and reliable voltage regulation even under high current applications. The device is also highly temperature stable, so it can handle extreme temperature changes without losing its characteristics. Additionally, the RLZTE-1139B is inexpensive, which makes it a popular choice for enthusiasts and those on a budget.

In conclusion, the RLZTE-1139B is a single Zener diode that is used for a wide range of applications. It has many advantages, including low Zener Voltage, robust construction, and temperature stability. It can be used in consumer electronic devices, radios and televisions, medical equipment, and other industrial and automotive applications. The RLZTE-1139B is a reliable and cost-effective solution to voltage regulation and current protection.
