15KP85A-TP

500V 1500W Transient Voltage Suppressor [TVS] Diode, 15KP85A-TP is a reliable and robust protection solution in application fields such as in automotive circuits, general circuits, and power supplies. This device consists of a state-of-the-art silicone bipolar diode structure with a very low leakage current and extremely fast response time. It also has several advantages such as: low thermal resistance, and optimized mechanical performance for EMI suppression.

This device is designed to protect parallel-connected automatic assembly lines, general circuit boards, and supplies against voltage transients. 15KP85A-TP device is also designed to provide over voltage protection, up to 5 x its rated voltage.

This device consists of two main parts: the field-effect transistor (FET) and the diode. The FET is used to create a low-impedance path from the output voltage to ground during normal operation. The diode acts as a reverse biased steering device. When a current surge occurs, the FET is triggered and changes the voltage path from the output voltage to ground. This change in the path allows the transient surge to be shunted to ground and helps protect the circuit from damage.

The 15KP85A-TP device works by allowing a small amount of current to flow through its reverse-biased diode junction. When a surge or spike in voltage starts, the FET is triggered and changes the path of the current. This causes the voltage to drop to a lower level. When the voltage drops, the FET returns to its normal state, and the voltage is quickly restored back to its normal operating level.

This device is designed to work over a wide range of temperature, from -55 to +125℃. This allows it to be used in applications where temperature extremes occur. The device also has high power rating that can withstand up to 1500W. It also offers IEC surge withstand capability which provides protection for your device against electrical surges from both the AC supply and DC source.

The 15KP85A-TP TVS diode is an excellent choice for providing reliable and robust protection from over voltage surges. It has a fast response time and allows for a low leakage current, making it well suited for applications that require a fast reaction time. Additionally, the high-power rating and temperature range of this device make it suitable for use in a variety of applications.
