15KPA58C

Transient voltage suppressors (TVS) are discrete components designed to protect circuits from voltage spikes. TVS are usually made out of diodes and they do not dissipate power during normal operation. At the same time, they are able to absorb and clamp transient voltages to a safe level. The 15KPA58C TVS diode is a bi-directional Zener/Transient Voltage Suppressor (TVS), designed to provide a low threshold for maximum clamping voltage by far exceeding the ESD protection levels.

The 15KPA58C features a Zener diode combined with an ESD protection diode, and is therefore able to protect against both surge and ESD conditions. It is rated for an 8KV Human Body Model (HBM). HBM is a standard test method that is used to simulate a discharge from a human body. This high ESD rating for the 15KPA58C makes it suitable for use in any application where human interaction may be present.

The 15KPA58C has a High Temperature Operating Range of -55°C to +150°C. This makes it suitable for use in high temperature, highly reliable applications where a failure of the TVS diode could lead to catastrophic failure. The 15KPA58C also features a VBR of +/- 5 volts, a Reverse Standoff Voltage (VRWM) of 15V and a Low Maximum Reverse Leakage Current (IR) of 1 μA.

The 15KPA58C is suitable for use in many different application fields, such as automotive, consumer electronics and telecommunications. In automotive applications, the 15KPA58C can be used to protect against voltage spikes caused by electromagnetic interference (EMI). In consumer electronics, the 15KPA58C can be used to protect against voltage spikes caused by lightning strikes and power outages. In telecommunications, the 15KPA58C can be used to protect against power surges that may occur during long-distance calls.

The working principle of the 15KPA58C is based on the Zener Breakdown Cell. When a voltage greater than the breakdown voltage (the VRWM) is applied across the 15KPA58C, the Zener Breakdown Cell is activated and a voltage regulator is formed. This limits the voltage across the diode and prevents it from exceeding the breakdown voltage. At the same time, the ESD protection diode ensures that peak currents do not exceed the rated maximum.

In summary, the 15KPA58C is a bi-directional Zener/Transient Voltage Suppressor (TVS) designed to provide a low threshold for maximum clamping voltage by far exceeding ESD protection levels. It is suitable for use in many different application fields, such as automotive, consumer electronics and telecommunications. The 15KPA58C works on the principle of the Zener Breakdown Cell, which allows it to limit the voltage across the diode while still providing effective protection against spikes and surges.
