A5KP12A-G

TVS-Diodes, as their name implies, are devices built into a standard diode that act as voltage suppressors. They are essentially electrical insulation devices that help protect sensitive components from electrical surges, or transient voltages, such as those frequently caused by lightning strikes, electrostatic discharge (ESD), and other sources of overvoltage. They work by clamping the transient voltage to a safe level with minimal energy dissipation.

The A5KP12A-G is a bifurcated, two-lead TVS diode manufactured in Silicon-Germanium technology. It is designed for application fields requiring a high degree of electrostatic discharge durability and low voltage clamping. The device features two operating modes: a high-power positive transil mode, and a low-power reverse bias avalanche mode.

The device is well-suited for use in ICT (In-Circuit Testing) applications, where transient voltages of up to 12VDC can occur. It is also used in automotive, industrial, and consumer electronic applications, where protection against ESD, radiofrequency interference (RFI) pulses, and other transient voltages is necessary.

In high-power positive transil mode, the A5KP12A-G bursts and quickly clamps the transient voltage to a safe level with minimal energy dissipation, allowing the equipment to remain operating within its design specifications. In low-power reverse bias avalanche mode, the device prevents high levels of transient voltage from reaching sensitive components while preventing the destruction of the device due to avalanche breakdown.

The A5KP12A-G is also designed to meet the European IEC61000-4 series of standards, which provide a wide range of environmental requirements for electrical and electronic products. The device is rated at IEC ESD level 3, meaning it is capable of withstanding a human body model (HBM) discharge up to 15kV.

Overall, the A5KP12A-G is an excellent choice for application fields that require protection against transient voltages. It features a robust design, and is built with Silicon-Germanium technology that affords a high degree of electrostatic discharge durability and low voltage clamping. The device is rated at IEC level 3, allowing it to easily meet the requirements of many industrial and consumer electronic applications.
