TVS (Transient Voltage Suppression) diodes are an integral component in the protection of circuits from transient voltage events. The P4SMA16A R3G is part of a family of ultra-low capacitance TVS diodes, designed for greater efficiency and maximum protection in frequencies up to 10GHz. The P4SMA16A R3G is a very high speed TVS diode, capable of responding to fast transients with minimal capacitance. It offers protection of up to 8kV (DC+AC) peak pulse voltage without following current relative to the input signal.

In the context of application field, the P4SMA16A R3G is suitable for use in many communication and data systems, including mobile networks, telecommunication networks, cable television, and wireless communication. It is an excellent choice for use in systems that require a robust level of protection, but the actual use will depend on the specific application. The P4SMA16A R3G can be used in a variety of other applications such as: automotive and home theater systems, avionic systems, and military and medical systems.

Working Principle

The P4SMA16A R3G is a low capacitance TVS diode with an advanced avalanche breakdown technology. This technology ensures that the diode responds to fast transients with very low capacitance. The TVS diode is designed to absorb transient current without following the input signal. The energy is transferred to the diode and dissipated by a low impedance path to ground. The diode has a very fast response time, allowing it to respond in the nanosecond range.

When the P4SMA16A R3G is exposed to a high voltage surge, it works to absorb the energy and protect the circuit from damage. The diode is designed to clamp the voltage to a safe level, which is determined by the avalanche breakdown voltage of the diode itself. The breakdown voltage is preset and cannot be adjusted. At this voltage, the diode will start to conduct current and limit the voltage to the avalanche voltage. This is known as the “clamping action”.

The P4SMA16A R3G is designed to protect against very high voltages up to 8kV (DC+AC) peak pulse voltage. The diode can also absorb high transient currents up to 400A. The diode is capable of withstanding high repetition rates to 10GHz. Additionally, the diode is protected against static discharge with a peak voltage of up to 15kV.

The P4SMA16A R3G provides a high level of protection with a low capacitance. It is ideal for use in applications that require a robust level of protection, such as communication and data systems. The TVS diode can protect against transient voltage events and ensure the safety and integrity of the system.
