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 © 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 52.4mm Cathode Tape: Red Anode Tape: White 0.8mm MAX PACKAGING INFORMATION TAPE & BOX TAPE & REEL Product ID Label 150mm Inspection Hole (both ends) 330mm 255mm 75mm BULK 80±5mm 20mm 198mm Product ID Label 84mm Packaging TAPE & REEL TAPE & BOX BULK Reel Diameter / Box Size (mm) 330 255 x 75 x 150 198 x 84 x 20 Quantity (PCS) 5,000 5,000 1,000 Carton Size (mm) 370 x 370 x 420 400 x 273 x 415 459 x 214 x 256 Quantity (PCS) 25,000 50,000 50,000 Approx.
