Transient Voltage Suppression Diodes (TVS-Diodes, also called surge suppressors, varistors, or MOVs) are a class of passive electronic components used for protecting semiconductors, circuits, and systems from transient voltages, voltage surges, and electrical noise. They are typically used in electrical equipment and consumer electronics to provide additional protection from transient voltages, which can be damaging to the sensitive electronic components in the system if they exceed the designed working range.

The 1V5KE62A is a low-cost unidirectional TVS-Diode, designed for general protection against transients of up to 600W peak pulse power (Ipp) in the extended voltage range of 10 to 32 volts. It is a high-performance, small-sized device, capable of protecting various applications from transient voltage surges. This device features a fast response time of less than one nanosecond with a breakdown voltage of 12.6V, making it suitable for use in a wide range of applications.

The 1V5KE62A diode has a variety of applications, including the protection of automotive computer systems, 12V automotive systems, consumer electronics, and other systems, including medical and telecom applications. It is also suitable for use in industrial, commercial, and automotive applications, providing protection against voltage surges and electrostatic discharge (ESD) up to 8kV.

The 1V5KE62A diode is designed with a two-layer construction; the upper layer is designed to absorb a sharp transient voltage spike and the lower layer is designed to reduce the quiescent power dissipation. The device features a peak pulse power dissipation rating of 600W and an excellent peak-to-peak capacitance rating of over 27pF. The device also has an operating temperature range of -65°C to +150°C, making it suitable for use in a wide range of applications and environments.

The working principle of the 1V5KE62A diode is based on the phenomenon of avalanche breakdown. When the voltage across the diode exceeds the rated breakdown voltage, it causes a large number of electrons and holes to be created, resulting in a high current flow. This surge of current is what helps to reduce the overvoltage across the component, thereby providing the necessary protection against the transient voltage.

In summary, the 1V5KE62A diode is a great choice for applications requiring robust transient voltage surge, ESD, and electrostatic discharge protection. It is small-sized, easy to install, and highly reliable, making it ideal for a wide range of applications. It also features a low stand-by power consumption and a wide operating temperature range, ensuring reliable operation in all conditions.
