TZX3V3B-TR

The TZX3V3B-TR is a single Zener diode with an operating current of 500mA maximum. It provides reverse breakdown voltage from 3.3V to 3.5V. It is available in a DO-214AC (AKA SMA) package, which is tiny and solution-free from the interference problem faced by through-hole products.

Application field: The TZX3V3B-TR is used for voltage regulating and reference for electronic circuits, especially high-frequency and low-voltage circuits. It is also used in current limiting, voltage surge protection, temperature compensation, high frequency filters, and other circuits.

Working principle: The basic working principle of the TZX3V3B-TR Zener diode is rectification and breakdown. Rectification refers to how the diode changes an alternating (AC) current into a direct (DC) current. When an AC current is applied, the diode will allow current to flow through it and prevent it from reversing. As a result, the AC current is changed into a DC current.

The breakdown of the diode refers to what happens when the reverse voltage is beyond the breakdown voltage. The diode no longer acts like a rectifier but rather begins to conduct current in both directions as a Zener diode. In other words, when the reverse voltage across the diode is greater than its breakdown voltage, the diode will become a Zener diode and begin to conduct current in both directions equally.

The TZX3V3B-TR operates with a 3.3V to 3.5V reverse voltage and a 500mA maximum operating current. It will provide a stable voltage supply to the circuit when the current is higher than the maximum operating current. Additionally, it can provide a reliable over-voltage protection on the circuit as it will clamp the voltage when the input is greater than the maximum operating voltage.

In conclusion, the application field of the TZX3V3B-TR Zener diode includes voltage regulating and reference for electronic circuits, current limiting, voltage surge protection, temperature compensation, high frequency filters and other circuits. It operates with a 3.3V to 3.5V reverse voltage and a 500mA maximum operating current.
