TVS – Diodes

TVS – Diodes (Transient Voltage Suppression Diodes) are designed to protect sensitive electronic components from voltage spikes. They are used in a variety of electronic devices, ranging from mobile phones to automobiles. The M5KP85CA is a type of TVS-Diode used to protect circuits from electrostatic discharge (ESD).

M5KP85CA Application Field and Working Principle

The M5KP85CA is an axial leaded Uni-directional TVS Diode designed for use with +12V DC lines. It has an 8.0mm physical size, allowing for easy installation in tight spaces. It is rated for a maximum power of 20W. This TVS grows conductive when the voltage applied to its terminals exceeds its breakdown voltage. The device conducts current without breakdown until its peak power is reached.The M5KP85CA is used in various devices, such as:

• Automotive applications, providing surge protection for electronic components.
• Telecommunications systems, providing protection for high speed data lines.
• Computer systems, providing protection for PC motherboards.
• Industrial control systems, providing protection for automation systems.

The M5KP85CA is designed to provide protection against ESD strikes up to 4,500V, which is the industry standard for efficient ESD protection. It also provides a fast reaction time to suppress transient overvoltages. The maximum clamping voltage of the device is 11.5V, which ensures a safe operating environment for the attached circuits.

Circuit Design Considerations

When designing a circuit with the M5KP85CA, there are several considerations that must be taken into account. These include:

• The maximum peak pulse power rating should be lower than the 20W maximum limit of the device.
• The peak pulse current should not exceed the current rating of the device.
• The device should be connected directly to the lines it is intended to protect.
• The device should not be used in a switching application.
• The device should not be connected in parallel with other protection devices.
• The device should be operated within its ambient temperature range.

Conclusion

The M5KP85CA offers excellent protection agains ESD strikes, with a fast reaction time and reliable protection. By following the design considerations outlined above, a reliable and robust protection solution can be achieved. This device is suitable for use in a variety of applications, where reliable protection against ESD spikes is required.
