SPECIALS AVAILABLE INCLUDE: Nominal zener voltages between the voltages shown and tighter voltage tolerances. For detailed information on price, availability, and delivery, contact your nearest Motorola representative. ZENER VOLTAGE (VZ) M EASUREMENT：Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (TL) at 30°C ± 1°C, 3/8, from the diode body. 3) 4) Valid provided that leads are kept at ambient temperature at a distance of 8 mm form case. 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. ３ PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.cn
