ZPY12-TAP Discrete Semiconductor Products

A ZPY12-TAP is a single Zener diode designed for applications in the telecommunications industry. It has a breakdown voltage of 12V and is capable of withstanding 15V reverse bias levels. This diode is used to provide protection against overvoltage and transient voltage spikes, which can be caused by power surges, lightning strikes, or other electrical equipment failures.

The Zener diode is a type of diode that has a reverse breakdown voltage, also known as a Zener Voltage. When the voltage across the diode increases beyond its Zener voltage, it conducts an electrical current in the opposite direction. This effectively clamps the voltage across the diode so that it doesn’t increase any further.

The Zener diode is a two-terminal device and is typically connected in parallel with the load (i.e., the device being protected). At voltages below the Zener voltage, the diode appears as an open circuit, thus it doesn’t affect the load. At voltages above the Zener voltage, the diode conducts current and limits the voltage across the load. The Zener diode also acts as a voltage regulator by ensuring that the output voltage of the power supply does not rise above the Zener voltage.

The ZPY12-TAP is designed to have a high surge capacity of 30A, a low thermal resistance of 0.7°C/W, and a low capacitance of 3.2pF. Additionally, its TAP coating ensures enhanced resistance to moisture, dust and vibration, making it suitable for a variety of harsh operating conditions.

Overall, the ZPY12-TAP diode is an excellent choice for systems that require reliable overvoltage protection in harsh environments. It is used in various applications such as in telecommunication systems, power supplies, industrial control systems and medical equipment.
