Additional Details

The BZD27C20P RU has a stand-off voltage of approximately 20V, which means it starts conducting when the voltage exceeds this level. The 'C' designation indicates that it is a bidirectional TVS diode, meaning it can suppress voltage transients in both positive and negative directions. Key electrical characteristics include peak pulse power dissipation, forward voltage, and clamping voltage at a specific test current. The device is typically available in a DO-214AC (SMA) package. The 'RU' suffix may indicate specific packaging or compliance standards. It's crucial to consult the datasheet to get precise specifications like the exact clamping voltage, peak pulse current, operating temperature range, and storage temperature range. This information is essential for ensuring the diode is used within its safe operating limits.
