P4KE7.5A 400W 7.5V TVS Diode DO-41 | RUILON

The P4KE7.5A is a 400W transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and fast transient voltage spikes. With a 7.5V standoff voltage, it provides accurate low-voltage clamping, making it suitable for protecting modern low-voltage electronic systems and signal lines.

Encapsulated in a DO-41 axial leaded package, the device is designed for reliable through-hole mounting and offers strong mechanical stability for industrial and general-purpose applications. The P4KE series features fast response time, enabling it to quickly clamp transient overvoltage events before they can damage ICs, processors, or communication interfaces. Its glass-passivated junction ensures high reliability and stable performance, while low leakage current supports efficient circuit operation under normal conditions.

The bidirectional (A-type) design allows effective suppression of voltage spikes in both polarities, making it a versatile protection solution for a wide range of electronic systems.
