(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. 2 RATINGS AND CHARACTERISTIC CURVES 3
