JAN1N6144 Circuit Protection

TVS - Diodes

The JAN1N6144 is a transient voltage suppressor diode that helps to protect electronic devices from damage due to voltage transients. It is commonly used in cars, industrial equipment, and telecommunications systems to protect against electrical surges. The JAN1N6144 is a relatively small and inexpensive device that is typically used in board level designs.

Application Field

The JAN1N6144 is commonly used to protect low cost or sensitive electronic circuits against electrical transients caused by surges in voltage. The device is used in a variety of applications including:

• Automotive systems, such as engine control units and airbag controllers
• Telecommunications systems, such as switching centers and cellular base stations
• Industrial equipment, including PLCs, drives, and motor control systems
• Consumer electronics, such as laptop computers, DVD players, and mobile phones

The JAN1N6144 is also suitable for use in general purpose protection applications, such as circuit protection for microcontroller or power MOSFETs and protection from electromagnetic interference.

Working Principle

The JAN1N6144 is a unidirectional device that acts as a clamp to dissipate voltage transients. The device consists of a cathode, an anode and a P-N junction. When a transient voltage is applied to the device, the current flows through the junction, which serves as an open circuit, thereby limiting the voltage across the rest of the circuit. The transient current is then safely dissipated as heat.

The JAN1N6144 is designed to operate at breakdown voltages ranging from 5.6 to 180 volts. The peak pulse current is rated at 17 amperes and the clamping voltage is rated at 11.4 volts. The device is usually epoxy-encapsulated for protection against moisture and vibration. Additionally, the JAN1N6144 has a 12KV rating for surge immunity.

Conclusion

The JAN1N6144 is an essential component for protecting electronic circuits from electrical transients. It is a small and inexpensive device that offers robust protection against a variety of voltage transients. Due to its wide range of application, this device is a very popular choice for board-level design.
