(Pack of 5) P6KE440CA Bidirectional TVS Diode DO 15 Package
The P6KE440CA is a bidirectional Transient Voltage Suppressor (TVS) diode designed to protect electronic circuits from voltage spikes, surges, ESD, EFT, and other transient events. It belongs to the P6KE series, which is widely used for medium-power protection applications.
This device clamps high-energy transients to safe levels, offering excellent protection for AC lines, DC rails, and high-voltage signal interfaces. The CA suffix indicates bidirectional protection, making it suitable for AC or polarity-sensitive circuits.
Packaged in a DO-15 axial package, it provides high surge capability and robust protection performance.
