MAPLAD7.5KP20CA Circuit Protection

Transient Voltage Suppression (TVS) Diodes are critical protection devices, and the MAPLAD 7.5KP20CA series are widely used for protecting equipment and circuitry from voltage transients. These devices are designed to compliment a broad range of applications where electrical overstress (EOS) is likely to occur.

The MAPLAD 7.5KP20CA series offers a wide range of voltage ratings to suit different application requirements. This makes them suitable for equipment and circuit protection against overvoltages generated by electrostatic discharge (ESD), inductive loads or lightning strikes.

The MAPLAD 7.5KP20CA consists of a rectifier diode connected with a Zener diode for bi-directional ESD protection. The main purpose of the series is to provide overvoltage and transient protection in electronic systems. They provide increased reverse leakage current capacity, low ESD coupling effectiveness and good clamping ratio in lesser footprint package.

The MAPLAD 7.5KP20CA series can protect a broad spectrum of circuit configurations where protection against high voltage transients is needed. This series is typically used in:

• Portable electronic devices
• Telephone and communication equipment
• Computers and peripherals
• Consumer electronics
• Appliances and industrial equipment
• Lightning protection

Working Principle

The MAPLAD 7.5KP20CA series works on the principle of a Zener diode. A Zener diode is a silicon diode specifically designed to breakdown when a specific voltage is reached. This diode is then connected in series with a rectifier diode. The function of the rectifier diode is to prevent the flow of current backward. This prevents the breakdown voltage from further increasing.

The operation of the MAPLAD 7.5KP20CA is simple but effective. This series is able to absorb high-voltage transients, suppressing them to a safe level for the equipment and circuitry. In cases of high-voltage transients, the MAPLAD 7.5KP20CA will begin to conduct, absorbing and redirecting the energy away from the protected devices. Once the transient voltage reduces, the MAPLAD 7.5KP20CA will stop conducting, and the device will reset itself automatically.

In summary, the MAPLAD 7.5KP20CA series are versatile and efficient protection devices suited to a wide range of applications. By providing constant, robust protection, these devices can help protect critical electronic systems from voltage transients and surges.
