Additional Details

The P5.6KJ features a breakdown voltage of approximately 6.2 to 7.0 volts. It's crucial to consult the official Panasonic datasheet for precise specifications such as peak pulse power, clamping voltage characteristics, and operating temperature range. The device is typically available in a DO-214AC (SMA) package, ensuring efficient heat dissipation and easy mounting onto printed circuit boards.

Proper PCB layout is also important for effective surge protection. The TVS diode should be placed as close as possible to the input connector or the source of the surge to minimize inductance and maximize its protective capability.
