The 1PMT4621E3/TR13 is a single Zener diode. This component functions as a voltage regulator that serves to protect against overvoltage by shunting unwanted voltage away from sensitive components and circuits.

Designed for use in audio, video and data communications applications, the primary component of the 1PMT4621E3/TR13 contains both a Zener diode, responsible for regulating voltage, and a transient suppression diode, responsible for controlling high voltage spikes.

Application Field

The 1PMT4621E3/TR13 is designed for a variety of applications. In fact, it is well-suited for use in almost any electronic system that requires an active component capable of regulating voltage while limiting transient voltages. Typical applications include:

• DC power supplies
• Audio amplifiers
• Computers
• Automotive systems
• Telecommunications equipment
• RF/microwave systems

Working Principle

The 1PMT4621E3/TR13 operates on the principle of Zener diode breakdown. A Zener diode is a special type of diode that is characterized by having a high reverse breakdown voltage. This voltage is typically 5-6 times higher than the device’s rated forward breakdown voltage.

When forward biased, the power supply voltage across the pins of the device is increased up to the Zener breakdown voltage, thus regulating the voltage across the pins of the device and protecting against overvoltage.

The 1PMT4621E3/TR13 also features a transient protection diode that is designed to protect against sudden voltage spikes. When a voltage spike occurs, the diode will conduct current to protect against the sudden increase in voltage.

The 1PMT4621E3/TR13 is designed to be robust and reliable. It is able to withstand very high temperatures as well as long-term exposure to vibration, shocks and static electricity. It has a wide operating temperature range and is capable of handling a wide range of voltages and current.

Conclusion

The 1PMT4621E3/TR13 is a single Zener diode specifically designed for use in audio, video, and data communications applications. It operates on the principle of Zener diode breakdown and is able to protect against both overvoltage and high voltage transients.

The device is designed to be robust and reliable and offers a wide operating temperature range and is capable of handling a wide range of voltages and current. It is also able to withstand very high temperatures as well as long-term exposure to vibration, shocks and static electricity.
