BZW03D220-TR

Diodes - Zener - Single

BZW03D220-TR is a single zener diode ideal for applications in user-space-limited designs such as mobile phones, digital cameras, hard disk drives and other consumer electronics. The diode has a total power dissipation of 220mW and features a low voltage drop of 1.3V at 25mA. The diode’s low forward voltage drop of 0.7V at 25mA allows for excellent efficiency. The diode can be used as a voltage reference or protection circuit in consumer electronics.

Application Field

The BZW03D220-TR single zener diode provides regulated voltage as a reference for many consumer electronic devices such as mobile phones, digital cameras, hard disk drives, and other consumer electronic products. The diode is widely used in consumer electronic devices as a voltage reference or protection circuit. Its low voltage drop of 1.3V at 25mA and 0.7V at 25mA enable efficient operation.

The diode’s low power consumption, small size, and rugged construction make it an ideal choice for user space limited designs. Its voltage drop is suitable for many applications including surge protection, over-voltage protection, and power supply linear regulation. Additionally, its low voltage drop is also suitable for voltage clamp circuits in memory devices and other power supplies.

Working Principle

Zener diodes operate slightly differently than a normal diode. When the full forward current is applied to the zener diode, the applied voltage remains constant regardless of changes in load current, thus providing a constant voltage source. This voltage source, called the zener voltage, is determined by the zener diode’s physical characteristics. The Zener diode is so named because of the characteristic voltage control when the reverse current flows through the diode.

The BZW03D220-TR works by allowing a low current to pass through the diode when forward voltage is applied and then maintaining a constant voltage when the reverse voltage increases. This constant voltage, or zener voltage, is determined by the characteristics of the diode. This zener voltage, or breakdown voltage, is determined by the physical design of the diode and the doping of the semiconductor material used to construct the diode.

The BZW03D220-TR is designed to provide a low voltage drop of 1.3V at 25mA and 0.7V at 25mA. These voltage drops enable efficient operation of the diode and make the BZW03D220-TR ideal for applications that require a low voltage drop such as surge protection, over-voltage protection, power supplies and memory devices.
