Notes:
(1) Tested with pulses tp=20ms.
(2) Valid provided that leads are kept at ambient temperature at a distance of 8 mm from case.
(3) The BZX55-C0V8 is a silicon diode with operation in forward direction. Hence, the index of all parameters should be F
instead of Z. Connect the cathode lead to the negative pole.
