The 1N5955E3/TR13 is a zener diode typically used for voltage regulation. It has a power dissipation of 500mW, a zener voltage of 6.8V, and a breakdown voltage of 12V. In this article, we will take a look at the application field and working principles of the 1N5955E3/TR13.

When it comes to application, the 1N5955E3/TR13 is best used for voltage regulation in industrial, automotive and home circuits. It can also be used to create a reference voltage for circuits, as well as for EMI filtering, surge protection, and voltage regulation. Because of its low reverse leakage and small size, it is also suitable for use in portable electronic devices. As a transient voltage suppressor, it helps protect circuits from transients caused by high voltages or electrical arcs.

Now that we’ve explored its applications, let’s take a look at the inner workings of a 1N5955E3/TR13. It consists of an aluminum electrode and a silicon layer sandwiched together to form a diode structure. When the diode is reverse-biased, the voltage applied across the diode causes a depletion region to form at the junction. The depleted region consists of positive charge carriers (holes) and negative charge carriers (electrons). When the diode is forward-biased, the depletion region disappears allowing current to flow freely.

As a zener diode, the 1N5955E3/TR13 has two distinct working modes. When it is reverse-biased, the voltage applied to it causes minority carrier injection, causing the depleted region to expand and allow current to flow. This is the so-called “zener breakdown” phenomenon. When the diode is forward-biased, the current flows until it is limited by the diode’s circuit resistance. This allows it to act as a voltage regulator.

In summary, we have discussed the application field and working principles of the 1N5955E3/TR13. It is a zener diode typically used for voltage regulation, but can also be used for other tasks such as EMI filtering, surge protection, and voltage regulation. It works by forming a depletion region at the junction, which is then reversed by minority carrier injection. This allows current to flow and acts as a voltage regulator.
