BZW03D120-TR

The BZW03D120-TR device is a single Zener diode made from a wide variety of materials. It is often used as a protective element in a wide range of electrical and electronic applications.

The BZW03D120-TR diode offers a low-voltage, high-speed switching performance with low capacitance resulting in improved performance and reliability. With an operating junction temperature range from -65°C to +150°C, it can be used in a variety of applications, from automotive to consumer.

The BZW03D120-TR diode is designed for use as a protective element in a wide range of electronic applications, such as protection against voltage surges, voltage transients caused by inductive loads, and Electrostatic Discharge (ESD) protection, as well as in the protection of pulse generators. The diode also offers excellent thermal and power dissipation capabilities, withstanding up to 4500mA of continuous current.

The BZW03D120-TR Zener diode works on the principle of a Zener breakdown, where a reverse-bias voltage across the diode\'s junction causes electrons to be accelerated and disperse into the surrounding depletion region, creating electron-hole pairs. This raises the conductivity of the diode, allowing a current to flow, known as the Zener current. As the voltage across the diode\'s junction rises further, more electron-hole pairs are created, increasing the Zener current further, thus forming a voltage-current relationship.

The Zener current is a function of the device\'s junction temperature, voltage breakdown level, power dissipation, and build quality. It is highly temperature dependent, due to the thermal characteristics of the semiconductor material used in the device. It is also affected by the device\'s power dissipation and build quality.

The Zener current of the BZW03D120-TR Zener diode starts off at a very low level and increases exponentially with the rise in the reverse-bias voltage across the diode’s junction. This allows the diode to efficiently limit the applied voltage with a very low increase in power dissipation, making it an ideal choice for many applications where power dissipation is a major concern.

The BZW03D120-TR Zener diode is a versatile and reliable device suitable for many applications in the automotive, consumer, and industrial sectors. Its high switching speed, low capacitance, and voltage-current relationship make it an ideal choice for a wide range of applications. It can be used as a protective element to guard against high surge voltages, transients caused by inductive loads, and Electrostatic Discharge (ESD) protection, as well as in the protection of pulse generators.
