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. * 221 West Industry Court Deer Park, NY 11729-4681 (516) 586-7600 FAX (516) 242-9798 * * World Wide Web Site - http://www.sensitron.com * E-Mail Address - sales@sensitron.com * 2 of 4 SENSITRON SEMICONDUCTOR 1SMA4741-G-1SMA4764-G 1.0W SURFACE MOUNT ZENER DIODE Green Products Data Sheet 5208, Rev. ! 1SMA47xx-G MA 1800 1SMA47xx-G-T3 SMA 5000 Sensitron # $ !
