BZW03C20-TR Application Field and Working Principle

When it comes to diodes, Zener Single can be characterized as a low-power 200mW voltage regulator. The BZW03C20-TR is one of the many Zener Single diodes. It operates within a range of 1.4V to 78V, has a maximum current of 500mA, and can handle up to 200mW of power. In terms of their application field and working principle, BZW03C20-TR diodes can be used in power supply circuits, logic circuits, and memory circuits. They are also used in audio equipment and appliances.

These diodes operate on the principle of reverse bias. This means that when electricity flows in a reverse direction to the circuitry, it creates a weak reverse current which leads to a drop in the forward voltage. This is the Zener breakdown voltage. As this voltage is reached, an avalanche effect occurs, leading to a sudden increase in current. The Zener diode is then able to limit the voltage across its junction to a specific value, referred to as the Zener voltage.

The characteristic features of the BZW03C20-TR include low power consumption, low thermal resistance, low capacitance, and reverse leakage current as low as 0.5mA. It also features a high breakdown voltage. The diode also has low surge power loss characteristics, a low noise factor, and a low minimum operating voltage.

Unlike other diodes, Zener Single diodes can be used in a regulating circuit to maintain a constant voltage. This is because when the viewing voltage fluctuates, the current across the diode changes instantly. The current depends on the difference between the viewing voltage and Zener voltage, so when the viewing voltage is higher than the Zener voltage, no current will flow. On the other hand, when the viewing voltage is lower than the Zener voltage, current will be established.

BZW03C20-TR diodes can also be used to protect against over-voltage. When a device is subjected to voltage larger than the rating, the current that can flow through the device exceeds the rating. This causes damage to the device. By using the BZW03C20-TR diode, the over-voltage can be limited to a safe level through the use of a Zener diode.

In conclusion, Zener Single diodes such as the BZW03C20-TR are mainly used in applications where a low-power voltage regulator is required. They can also be used in power supply, logic, and memory circuits, audio equipment, and as over-voltage protection. The BZW03C20-TR in particular has an operating range of 1.4V to 78V, a maximum current capacity of 500mA, and can handle up to 200mW of power. It also features low power consumption, low thermal resistance, low capacitance, and low noise factor.
