The P6SMAJ85ADF is a surface-mount unidirectional Transient Voltage Suppressor (TVS)/Diode. It is mainly used for protecting up to a certain overvoltage and surge as well as for protecting sensitive semiconductor elements, such as transistors, diodes, integrated circuits and thyristors from transient overvoltage and surges on the application printed circuit board. This type of diode is also known as a voltage-clamping device as it is able to protect devices operating at voltages up to the peak pulse, without any breakdown currents in normal range of its operational voltage.The P6SMAJ85ADF uses the principle of avalanche breakdown protection (ABP) to offer protection against overvoltage and surge in the circuit. Avalanche breakdown occurs when a very high electric field is developed across a very small gap of material, when the electric field reaches a certain threshold, the barrier created by that material is abruptly broken down causing current to flow through the material and creating protective protection for the components in the circuit. The P6SMAJ85ADF incorporates two P-N junctions in series, thereby providing symmetrical single-directional protection.The P6SMAJ85ADF is designed to protect against transient overvoltages of up to 1000V biased at 8V. This ensures that no damage is done to the integrated circuits even when exposed to high voltage surges. It has a fast response time, typically below 1.5ns, and a low capacitance of around 6pF at 1MHz. This diode is built to provide a consistently low capacitance throughout the pulse width of the transient surge.The P6SMAJ85ADF is offered in the standard SOD-123 package, which is among the smallest packages for such type of diode. This allows it to be used in the smallest and most compact applications in space-limited devices.In summary, the P6SMAJ85ADF is a surface-mount unidirectional Transient Voltage Suppressor (TVS)/Diode mainly used for protecting sensitive semiconductor elements and providing overvoltage and surge protection on the application printed circuit board. It offers symmetrical, single-directional protection and a fast response time with a low capacitance. It is available in a small, SOD-123 package and can handle up to 1000V biased at 8V.
