PN412211 application field and working principle

P412211 is a diode array composed of three reverse connected PN junction diodes. It has direct current and surge current withstanding capabilities, fast reverse recovery time and excellent high temperature performance, making it suitable for telecom systems and other applications.

The application field of PN412211 includes rectification, switching, regulation and protection, etc. In the application, PN412211 can effectively prevent system from being damaged by transient surge current, two-way over voltage and photovoltaic cells reverse current, thus providing affective protection for a system.

Working principle

As we all know, PN junction diode is composed of p-type semiconductor and n-type semiconductor. Due to the existence of p-n junction, PN junction diode has the characteristics of non-conduction in the reverse direction. At the same time, when the forward voltage is applied, the electric current can be conducted. Under reverse direction and under reverse current, PN412211 will not be reversed and breakdown, therefore, PN412211 has excellent transient current resistance, surge current block and overvoltage protection.

Under normal reversal, PN412211 is just an diode, it can block all kinds of transient current, surge current and over-voltage.

Conclusion

PN412211 is a reverse-connected diode array which consists of three PN junction diodes. It is suitable for telecom systems and other applications due to its direct current and surge current withstanding capabilities, fast reverse recovery time and excellent high temperature performance. In addition, PN412211 can effectively prevent system from being damaged by transient surge current, two-way over voltage and photovoltaic cells reverse current, thus providing affective protection for a system.
