The 1N5944BPE3/TR12 is typically used up to a reverse voltage of 9V, and it has a low series resistance for reverse conduction. The maximum power dissipation for this diode is 500mW, and it can operate in high speed switching applications up to 150°C. It is a RoHS compliant device, and it has been designed with a small, low profile surface mount package that is ideal for limited space applications.

Working Principle

The working principle of the 1N5944BPE3/TR12 is fairly simple. When the diode is connected up to a voltage source and the reverse bias voltage is greater than the Zener voltage, the diode is then said to be in “breakdown”. The Zener voltage is typically denoted by Vz, and it is the maximum reverse voltage that the diode can withstand before it reaches breakdown. When breakdown occurs, the diode can conduct current in the reverse direction.

Once breakdown has been achieved, a large amount of current is passed through the diode, and the Zener voltage remains the same even as the current passes. This is what makes Zener diodes so useful; they provide a stable voltage reference throughout a variety of conditions. Since the 1N5944BPE3/TR12 operates up to 9V and it is a single diode, it can be used in an array of applications such as computer power supplies, automotive systems, and consumer electronics.

When the reverse voltage of the diode is lower than the Zener voltage, it will not be ‘on’ and it will not conduct current in the reverse direction. This allows the diode to be used for voltage regulation in circuits, since it is able to maintain a stable voltage over a variety of operating conditions.

The 1N5944BPE3/TR12 is an excellent example of the modern Zener diode. With its robust construction, high performance, and reliable operation, it is an ideal choice for a broad range of commercial and industrial applications. It offers excellent stability, low cost, and a variety of useful features for many different purposes.
