Medical electronics, including electronic medical imaging devices and specialty analyses.

Working Principle

The working principle of the JANS1N4996US is ba sed on the Zener effect. When a voltage is applied across the anode and the cathode of the diode, electrons are attracted to the anode and travel through the diode. As the voltage increases, the flow of electrons is restricted, creating an electrical barrier in the diode called the "Zener Barrier". As the voltage across the diode continues to increase, the Zener barrier begins to break down, allowing the current to pass through. When the set voltage reaches the breakdown voltage of the diode, the current flow through the diode will stay steady and be limited by the Zener barrier.

Conclusion

The JANS1N4996US single diode Zener diode is an ideal choice for a variety of applications including automotive, industrial and military electronics. The diode features a high surge current rating, low forward voltage drop and low leakage current, making it suitable for a variety of uses. With its wide operating temperature range and fast switching capabilities, this diode is a reliable and efficient solution for circuit protection, signal detection and signal switching applications.
