ZENER VOLTAGE (Vz) MEASUREMENT Nominal zener voltage is measured with the device function in thermal equilibrium with ambient temperature at 25 OC NOTE 4. ZENER IMPEDANCE (Zz) DERIVATION Zzt and Zzk are measured by dividing the ac voltage drop across the device by the accurrent applied. The specified limits are for Iz(ac) = 0.1 Iz, (dc) with the ac freqency = 60Hz STAD-FEB.10.2009 1 PAGE . 4 1SMA5921~1SMA5942 MOUNTING PAD LAYOUT ORDER INFORMATION • Packing information T/R - 7.5K per 13" plastic Reel T/R - 1.8Kper 7” plastic Reel LEGAL STATEMENT Copyright PanJit International, Inc 2009 The information presented in this document is believed to be accurate and reliable.
