    Note:

    In the description for Above Table 1/10/11/14, the letters indicate the polarity of the electronic component, while the symbols in parentheses indicate the polarity of the external power supply.

    The MPD operates under negative voltage; therefore, the MPD polarity is opposite to the external power supply polarity.
