The 1N5995B-TP is a Zener diode from the single diodes category, designed for use as a part regulator in situations where the output voltage stays within a certain range. The basic idea behind Zener diodes is to use the breakdown voltage of silicon to form a circuit with a “stable” voltage on both sides. The breakdown voltage can be varied by changing the amount of dopant implanted in the diode.

The 1N5995B-TP is a silicon planar zinc oxide diode chip packaged in a DO-41 or SOD-123 package. The maximum current rating is 5.0 A, with a typical power dissipation of 400 mW. The breakdown voltage of the diode is between 17.6 and 19.6 V, with a reverse current equal to the zener rating. The zener voltage is factory determined, so the voltage rating of the diode remains the same regardless of the current it is carrying.

This diode is actually intended for use in linear voltage regulators, but has a few other applications as well. One of them is to limit the current in isolated materials connected to a device such as a transformer. This can be used, for example, to limit the current in large transformers used in switching power supplies.

The 1N5995B-TP is also used as a short-circuit protection device. When a short-circuit occurs, the diode will limit the current, and the voltage will drop. This limits the amount of energy that can be lost due to the short-circuit. In combination with other components such as resistors and inductors, it can be used as a current protection circuit to limit over-currents in certain circuits.

The working principle behind the 1N5995B-TP is relatively simple. When a reverse voltage is applied to the diode, electrons move from the N-type region, across the gap and into the P-type region. As the voltage increases, more electrons move across the gap and start to build up a depletion region. At a certain point, the depletion region can no longer hold the electrons and the voltage increases suddenly, creating a negative voltage spike and a subsequent reverse current.

When a forward voltage is applied, the electrons in the depletion region start to move in the same direction, creating a current flow. The diode has a low forward voltage drop, so the voltage on the N-type side is always slightly lower than the voltage on the P-type side. This creates a voltage drop across the diode, which helps regulate the voltage on the N-type side, keeping it within a certain range.

The 1N5995B-TP is a small, inexpensive, and reliable Zener diode that can be used in a wide range of applications. Its low forward voltage drop and stable breakdown voltage make it ideal for use as a voltage regulator, current protection, and short-circuit protection device.
