P4SMA20CAHE3/61 Circuit Protection

TVS - Diodes

Transient Voltage Suppressor (TVS) Diodes are a form of semiconductor-based voltage driven protection devices. They are primarily used to protect electronics and other sensitive circuits from damage due to lightning strikes, over-voltage occurrences, and electrostatic discharge (ESD).

The P4SMA20CAHE3/61 is one of the latest TVS diodes in the market. It is designed to provide ultra-low capacitance and low clamping voltage features. It has an insulated power storage element that helps to reduce power loss and maintain a higher surge current load. The diodes are also capable of supporting large 10/1000μs waveshapes.

The P4SMA20CAHE3/61 offers a wide protection range and offers high pulse power dissipation capability (PPM). The device has a wide operating temperature range of -55℃ to +150℃. It is also highly reliable and a major advantage associated with this TVS diode is that it does not suffer from latch up or multiple pulsing during periods of high surge.

Application Field and Working Principle

The P4SMA20CAHE3/61 TVS diode is commonly used in a wide range of electronic and electrical systems. It offers a wide operating voltage range of 2-20V and the device can be used to provide surge protection for cables carrying data between two devices or systems. The diode is also used in circuits with a wide variety of functions, such as motor controllers, IGBT inverters, and LED drivers.

The working principle of the P4SMA20CAHE3/61TVS diode is the same as most other TVS diodes. When a voltage greater than the breakdown voltage occurs in the system, the diode is activated and the voltage is redirected through the diode and dissipated as heat. This dissipated energy is then either released into the environment or dissolves into the ground plane, thus, protecting the sensitive circuits from damage.

In addition, this TVS diode also comes with a Reverse Standoff Voltage (RSV) feature. This feature ensures that the diode does not conduct current at normal operating voltage. The RSV voltage can be set to a specified level that matches the system\'s operating voltage.

The P4SMA20CAHE3/61 TVS diode is an ideal protection solution for a wide range of applications. It withstands high overvoltage and high capacitive transients with minimal power dissipation and a low temperature rise. It is also highly reliable and can handle multiple surge pulses with superior reliability and performance.
