Tolerance designation — The type numbers listed have zener voltage min/max limits as shown. Device tolerance of ±2% are indicated by a “B” instead of a “C”. Zener voltage is measured with the device junction in thermal equilibrium at the lead temperature of 30°C ±1°C and 3/8, lead length. 3) ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current applied. The specified limtis are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 1.0 kHz. 4) This data was calculated using nominal voltages. The maximum current handling capability on a worst case basis is limited by the actual zener voltage at the operating point and the power derating curve. ３ PDF 文件使用 "pdfFactory Pro" 试用版本创建 www.fineprint.cn
