Coefficient at IZK Ta = 25℃ 1) Tested with pulses tp = 20 ms. 2) The BZX55C0V8 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. 3 Website: www.kingtronics.com Email: [email protected] Tel: (852) 8106 7033 Fax: (852) 8106 7099 BZX55C Note: Specifications are subject to change without notice. 4
