30KPA156A-B Circuit Protection

The 30KPA156A-B TVS - Diodes is an integrated, unidirectional, semiconductor, device specifically designed to protect signal lines from voltage transients induced by external sources or wiring inductance. It operates like a voltage-variable lightbulb that absorbs transient energy; while it will not conduct during normal operation. It provides very fast protection between common signal and ground potentials, thus protecting the system from voltage overshoots due to switching currents in inductively loaded lines.

30KPA156A-B offers low power loss and fast response to prevent voltage overshoots and undershoots due to inductive loads. It has fast response time down to 1-nanosecond to ensure transient waves are not clipped. The device is designed with multiple breakdown voltages to allow different system scenarios with one device. It has a variety of safety features to protect against electrical over-stress and short circuits.

The 30KPA156A-B has a variety of practical applications in the automotive and consumer electronics industries. It is often used to protect devices subject to electrical over-stress due to inductively loaded or high current switching on a circuit, such as motors, automotive ECUs, and either consumer electronics or industrial systems, including lighting and solar. It is also commonly used in signal lines to protect against ESD, AC and RF noise, and in power supply isolation against overvoltage.

30KPA156A-B has a basic working principle which is based on PN junction diode rectification. When a PN junction diode is subjected to a voltage greater than its breakdown voltage, it begins to conduct current and thereby letting out the voltage transient event. The 30KPA156A-B is designed to clamp down on voltage transients with a breakdown voltage range of 3000 Volts (minimum). This allows it to suppress unwanted voltage transients with extreme reliability.

The device has a small size and allows for a compact footprint with high power compliance. Its pre-conditioning technology helps to ensure reliable and consistent performance throughout the life of the device. Additionally, the device has a watchdog circuit which prevents it from negatively affecting other components in the circuit due to overstressing. The built in self-protection feature of the device helps it recover quickly from continuous transient events.

The 30KPA156A-B is an ideal choice for a wide range of applications from consumer electronics to low power automotive and industrial systems. It is designed for use in various voltage protection applications and offers excellent protection capabilities in environments with high surge activity and transient voltages. With its reliable performance and wide operational range, it proves to be an effective way of protecting electrical and electronic systems against overload, spike, and transient voltage related damage.
