Type numbers listed have standard tolerance on the nominal zener voltage of 5%. 2. Measured under thermal equilibrium and DC (IZT) test conditions. 3. The Zener impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. 1N4728A - 1N4764A 2 of 4 (c) 2006 Won-Top Electronics MARKING INFORMATION TAPING SPECIFICATIONS 0.8mm MAX 5mm 1N 4 7x x A WTE Cathode 1N47xxA xx WTE = Polarity Band = Device Number = 28, 29, 30...to 64 = Manufacturer's Logo 1.2mm MAX 6mm 0.8mm MAX 52.4mm Cathode Tape: Red Anode Tape: White PACKAGING INFORMATION TAPE & BOX TAPE & REEL Product ID Label 150mm Inspection Hole (both ends) 330mm 255mm 75mm BULK 805mm Product ID Label 20mm 84mm 198mm Packaging Reel Diameter / Box Size (mm) Quantity (PCS) Carton Size (mm) Quantity (PCS) Approx.
