STMicroelectronics P6KE440ARL Transient Voltage Suppressor

The P6KE440ARL from STMicroelectronics is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other sudden voltage events. This TVS diode is a critical component for safeguarding circuits by clamping overvoltage events without sustaining damage.

Key Features

• Peak Pulse Power: The P6KE440ARL offers a peak pulse power dissipation of 600 Watts at 10/1000μs waveform, which is a standard transient threat profile, ensuring that it can handle significant power surges.
• Stand-off Voltage: It has a stand-off voltage of 376 Volts, which is the maximum voltage that the diode can withstand without conducting in its off state.
• Breakdown Voltage Range: The device features a breakdown voltage range from 418 to 462 Volts, providing a margin of safety beyond the stand-off voltage to prevent premature clamping.
• Low Leakage Current: With its low leakage current, the P6KE440ARL ensures minimal power loss when the device is in the standby mode, thus enhancing the efficiency of the application it is used in.
• Response Time: The diode boasts an exceptionally fast response time, typically less than 1 picosecond from 0 Volts to BV min, ensuring quick protection for sensitive circuits.
• Package: Available in a DO-15 axial lead package, the P6KE440ARL is designed for easy installation and is compatible with various PCB layouts.
