TVS - Diodes

Protecting a circuit against electrical transients involves mitigating the destructive electrical energy they bring. Transient Voltage Suppression (TVS) diodes provide a crucial component of an effective surge protection system as they are designed to clamp a level of voltage and current that is lower than the intrinsic breakdown of the system.The JAN1N6167A is a 1500 W unidirectional Transient Voltage Suppressor (TVS) diode and it provides high surge withstand capability and class-leading clamping performance. As it is made of a PNpn junction it is able to absorb and dissipate high voltage spikes, thus minimizing its voltage swing range. JAN1N6167A offers fast response time, excellent clamping capability and low-to-zero leakage current.The device is an ideal solution for protecting high-speed data lines from inductive and capacitive transients. With an operating temperature range of -55°C to 125°C and a working breakdown voltage of up to 5.7V, it can protect signals up to 5MHz, making it suitable for various industrial, automotive, medical and consumer application.The JAN1N6167A is a single-pole, bidirectional device that contains two diodes connected back-to-back, hence it can protect against both positive and negative transients. It is characterized for unidirectional operation and offers two levels of suppression that is decided by the current flowing through the device. Its Response Time is 25 Nano-seconds, faster than most other similar devices.The operation of the device can be understood by analyzing the dynamic resistance characteristics of the device while passing the pulse current in one direction. The forward-voltage characteristics of the diode is negative as the forward voltage drops with the increase of current in the forward direction. On the other hand, the reverse voltage characteristics of the device is positive because the voltage increases as the current increases in the reverse direction. This implies that when increasing voltage and current pulse occurs, the PNpn junction present in the device will rapidly avalanche when its breakdown voltage is exceeded.The breakdown voltage of the JAN1N6167A can be set to one of two levels depending upon the applied current surge. At the higher level, it can with stand greater voltage and current transients. The device also offers low holding current over a long term application.The output capacitor of the device will prevent high frequency transients from damaging the circuit. The fast response time of the device prevents voltage transients from damaging the circuitry and it also attenuates EFT and ESD pulses.In conclusion, the JAN1N6167A is an ideal solution for protecting high-speed data lines from inductive and capacitive transients. Its fast response time, excellent clamping capability and low to zero leakage current make it suitable for various industrial, automotive, medical and consumer application. The device is a single-pole, bidirectional device that can protect against both positive and negative transients and it offers two levels of suppression that can be determined by the current surge applied to the device.
