TVS diodes, or transient voltage suppressor diodes, are a type of solid-state P-N junction, specifically designed for protecting sensitive electronic equipment against high voltage spikes. P6KE250AHR0G is a TVS diode from PAN JIT of Taiwan. In this article, we\'ll analyze the application field and working principle of P6KE250AH0G.

Application Field

P6KE250AHR0G is an ultra wide-bandwidth bi-directional diode, designed to offer more reliable protection from lightning strikes and electrical transients. It comes in SMA (surface mount), DO-15, D2PAK, and other package styles. The datasheet of P6KE250AH0G indicates that it has the following application fields:

• Power Supplies
• Telecom Applications
• Medical Systems
• Computer Systems
• Automotive Electronics
• Portable Electronics
• Industrial Equipment

This TVS diode can also be used for other ESD (electrostatic discharge) protection applications, as it can absorb large surge currents and complete high surge current test requirements. Hence, it is a great choice for applications where both safety and reliability are required.

Working Principle

TVS diodes usually use a simple, P-N junction structure. This type of structure allows a certain voltage and current to pass through, while blocking higher voltages and currents. For example, when the voltage applied to a P-N junction diode is within its reverse breakdown voltage range (VBR), only a small reverse current (Io) will flow through it. When the voltage exceeds the VBR, the excess voltage will be dissipated as heat and the reverse current will increase exponentially. This process is called "avalanche breakdown".

The working principle of P6KE250AHR0G is basically the same. Its datasheet indicates that this TVS diode has a reverse standoff voltage (VRWM) of 250V, meaning it can suppress voltage up to 250V. It also has a surge current capability of 12.5A, meaning it can absorb up to 12.5A of current. In other words, this TVS diode can effectively protect circuits from transients up to 250V and 12.5A. This makes the P6KE250AHR0G an ideal choice for applications such as data ports protection, medical device, and automotive electronics.

Conclusion

The P6KE250AHR0G TVS Diode from PAN JIT of Taiwan is a great choice for a wide range of applications. Its application fields include power supplies, telecom applications, medical systems, industrial equipment, computer systems, automotive electronics, and portable electronics. Its working principle is based on P-N junction structure, which offers reliable protection from transients up to 250V and 12.5A. Hence, P6KE250AHR0G is an ideal choice for applications requiring both safety and reliability.
