1PMT4621E3/TR7 Application Field and Working Principle

1PMT4621E3/TR7 is a single Zener diode component from NXP Semiconductor. It is used for a variety of applications, including power management and signal switching as well as input protection.

Zener diodes are a type of diode that is specifically designed to conduct current when its breakdown voltage, known as the Zener voltage, is exceeded. When forward bias is applied the diode acts like a regular diode, allowing current to flow in one polarity of the applied voltage. When the Zener voltage is reached, the diode changes its resistance levels from low to high and current begins to flow in the opposite direction. This characteristic allows Zener diodes to be used for voltage regulation, power management, and signal switching.

The 1PMT4621E3/TR7 diode\'s forward voltage is 250mV at a maximum of 500mA. Its maximum reverse voltage is 33V and it is able to handle a maximum power dissipation of 300mW. Its maximum current leakage at 5V is 500nA. Its Zener voltage ranges from 6.2V to 7.8V.

The 1PMT4621E3/TR7 can be used in a variety of applications, such as as input protection, signal switching and power management. It can be used to provide voltage regulation when the voltage exceeds the Zener voltage, or as a power switch in circuits that require an additional power source such as VCC. It can be used as ESD protection, overvoltage protection and RF noise suppression.

The 1PMT4621E3/TR7 diode is protected against electrical overstress (EOS) by a wave shaping network. This allows the diode to maintain its characteristics even when subjected to high frequency waveforms, ensuring steady, dependable operation. Its small size and low power consumption make it suitable for compact, mobile and handheld devices.

In summary, the 1PMT4621E3/TR7 is a single Zener diode from NXP semiconductors which is suitable for a variety of applications, ranging from voltage regulation to ESD protection. Its wave shaping network protection allows it to maintain its characteristics when subjected to high frequency waveforms, making it ideal for use in mobile and handheld devices.
