P6KE91AE3/TR13

The P6KE91AE3/TR13 is a special type of Transient Voltage Suppression (TVS) diode that is highly suitable for protecting circuits from voltage transients. It is often chosen as the most reliable component for this purpose due to its capability to absorb large electrical surges. This TVS diode is designed to work in a wide variety of applications and offer superior protection from these dangerous events.

Applications

The P6KE91AE3/TR13 can be used in a wide range of applications and industries. It can be used in automotive systems, medical devices, power semiconductor circuits, RF/microwave circuits, dynamic random access memory (DRAM) circuits and DC-to-DC converters. It can also be used for protecting various electrical assemblies and displays, as well as in industrial applications including welding equipment, spacecrafts, vehicle navigation systems and solar power systems among many others.

Working Principle

This TVS diode uses the avalanche breakdown phenomena, or the P-N junction breakdown, to protect circuits from voltage transients. When the voltage exceeds the diode’s breakdown rating, the current will start to surge and it creates an avalanche of electric carrier multiplication. This further increases the current, resulting in the protection of the circuit. The breakdown rating of the diode is matched with the clamping voltage so that the current will not damage the circuit.

The P6KE91AE3/TR13 does not require a line regulation and has an ability to clamp transients up to 800W peak per line. It also meets the requirements of the IEC 61000-4-2 level 4 electrostatic discharge testing. The high speed response time of this TVS diode is between 1.5 – 6 ns, ensuring that it is able to protect circuits from voltage transients quickly.

Conclusion

The P6KE91AE3/TR13 is a reliable TVS diode which is widely used for circuit protection from voltage transients. Its wide range of applications and its ability to protect and clamp transients quickly and safely makes it highly effective in many applications. The avalanche breakdown technology also ensures that the circuit is not damaged if the voltage transient exceeds the breakdown voltage.
