Working Principle

The TZQ5221B-GS08 consists of a semiconductor junction between n-type and p-type semiconductor layers. When a voltage is applied that exceeds the diode\'s breakdown voltage, current begins to flow through it. The diode functions as a short circuit in this state and all of the applied voltage drops across the diode. This voltage is known as the zener voltage.

A zener diode typically performs two different functions in an electrical circuit. First, it acts as a regular silicon diode which conducts current in the forward direction, allowing current to flow in one direction only. Second, it behaves as a voltage regulator, allowing current to flow in the reverse direction when the voltage across it exceeds its zener voltage. This action, known as zener breakdown, provides regulated voltage at the output.

The TZQ5221B-GS08 is designed to be used in a variety of applications, including reverse-polarity protection, overvoltage protection, EMI filtering, current limiting, transient suppression and voltage clamping. Its low-profile SOT-23 package makes it suitable for high-density surface mounting on printed circuit boards.
