JAN1N4966C Application Field and Working Principle

The JAN1N4966C series of Zener diodes is a single, medium power semiconductor device with application fields that include voltage regulation, surge protection, voltage clamping, and data protection. It provides a low-cost alternative to many popular current-limiting and voltage-protection components. The JAN1N4966C series is supplied in both Through Hole (TH) and Surface Mount (SM) packages, making it suitable for a wide range of applications.

Application Field of JAN1N4966C

The JAN1N4966C series of Zener diodes has a large application field and is used for a variety of tasks, for example:

• Linear voltage regulation
• Surge protection
• Voltage clamping
• Data protection
• Software controlled power regulation
• Overvoltage protection
• Load protection

The JAN1N4966C series is also suitable for areas where low-cost alternatives are needed, such as power supplies and safety grounding systems.

Working Principle of JAN1N4966C

The JAN1N4966C series of Zener diodes is comprised of a single diode, unlike many of its counterparts which consist of two diode and transistor pairs. This single diode design allows for a low Vz, or “breakdown” voltage, which enables the device to provide surge protection.

The basic operation of the JAN1N4966C series is to provide a clamped output voltage when applied with an input voltage of greater than the breakdown voltage, Vz. This output voltage is determined by the Zener voltage of the diode, which is set by the manufacturer. The output voltage is then determined by the input voltage and the Zener voltage.

When the input voltage is reversed, the JAN1N4966C will then serve as an isolation diode, providing protection against accidental reverse bias of the output. The JAN1N4966C is commonly used to protect sensitive circuitry against transient voltage spikes or to provide a regulated voltage source.

Conclusion

The JAN1N4966C series of Zener diodes is a durable, low-cost alternative to popular current-limiting and voltage-protection components. Its single diode design allows for a low breakdown voltage, providing surge protection and output voltage regulation. With its wide application field, the JAN1N4966C series is suitable for a wide range of applications, from linear voltage regulation to data protection.
