NOTE:
1. Tolerance and Type Number Designation. The type umbers listed have a standard tolerance on the nominal zener
voltage of + 5%
2. Specials Available Include:
A. Nominal zener voltages between the voltages shown and tighter voltage tolerances.
B. Matched sets.
3. Zener Voltage (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining
o
o
the lead temperature (T
L
) at 30 C + 1 C, from the diode body.
4. Zener Impedance (Zz) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when
an ac current having an rms value equal to 10% of the dc zener current (Izt or Izk) is superimposed on Izt or Izk.
5. Surge Current (Ir) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak,
non-repetitive, reverse surge current of 1/2

唯有可视化、可体验的方式方可快速确立人的静电防护意识与配合积极性
在现今充斥各种IC(集成电路)的电子制造领域里,几乎很难找到哪家企业全然不了解静电防护(或ESD防护)的必要性。但每家电子制造企业的静电防护执行层面却参差不齐。而工厂的静电防护是一项系统管理工程,涉及到供应商、进料检验(IQC)、电子仓库(EEW/H)、生产备料(MaterialKitting)、生产制造(MFG)、生产工程(Engineering)、测试(Testing)、电子维修、失效分析(FailureAnalysis)、品质保证(QualityAssurance)等多区域、...
