TVS (Transient Voltage Suppressors) diodes are specially designed components made to prevent electrical components from suffering damage due to overvoltage transients. P6KE20AE3/TR13 is one of such diodes. It is designed to protect signal lines and other circuits by providing a high surge capability and satisfying demanding transient pulse requirements.

Application Field

P6KE20AE3/TR13 comes with glass beads design that directly mounts on the board. It is designed to provide a peak power dissipation of 360W (10/1000μs) and a clamping voltage of 20V (7V typical). It is suitable for moderate surge application including:

• Automotive applications.
• Lighting.
• White goods.
• Industrial control equipment.
• Mains and line protection.
• Communication systems.

Working Principle

P6KE20AE3/TR13 is a movable-junction transient voltage suppressor. Its principle of action explains the way in which this device acts as a protector to electronic components. When the TVS is subjected to a voltage spike, typically due to a lightning strike or the discharge of electrostatic potential, it will switch from a normally non-conductive state to a conductive state, thus limiting the voltage of the system.

When the voltage reaches the breakdown voltage, the diode will switch from the non-conductive state to the conductive state. As a result, the excess voltage bleeds off to ground and the voltage at the input terminal will be limited. Once the voltage returns below the normal operating voltage, the diode will switch back to its non-conductive state, thus protecting the system from further voltage spikes.

P6KE20AE3/TR13 has very low leakage current and a fast response time to minimize the negative effects of voltage spikes. It is a surface-mount device and can be combined in a series or parallel configuration for higher voltage or current protection requirements.

Conclusion

P6KE20AE3/TR13 is a reliable transient voltage suppressor designed to protect sensitive electrical components from being damaged or destroyed due to voltage spikes. It is suitable for moderate surge applications such as lighting, white goods, industrial control equipment, mains and line protection, and communication systems. The fast switching feature helps minimize the negative effect of over-voltage transients by allowing the voltage to be bled off to ground quickly. The P6KE20AE3/TR13 is an effective TVS diode for reliable protection.
