Additional Details:

The RKZ22BJKUP6 typically has a reverse standoff voltage of around 22V. The suffix 'UP6' likely relates to specific packaging or qualification standards. It has excellent clamping characteristics to ensure protected circuitry is exposed to minimal voltage stress. It comes in a small surface mount package, likely a SOD-323 or similar, to permit high-density board layouts. You can find detailed information on surge current ratings, clamping voltage, and other key specifications in the product datasheet. The TVS diode provides unidirectional protection and is suited for sensitive electronic applications in diverse conditions.
