400 MW ZENER DIODES DIODES LIMITED DI-957-DI-976 SERIES FAIRACRES ESTATE, DEDWORTH ROAD, b WINDSOR, BERKSHIRE. Telephone: WINDSOR 69571 Telex: 847255 SEMICONDUCTOR MANUFACTURERS The Diodes Limited Zener types listed below are plastic encapsulated counterparts of the JEDEC devices produced under the corresponding IN number in the DO-7 package. Large junction area and solid internal construction result in low junction temperatures and high reliability at extremely low cost.

For +5% tolerance specify suffix B. NOTE 2: The Zener impedance (Zzt and Zzk) are derived from the 60 Hz AC voltage which appears across the Zener when an AC current having an rms value equal to 10% of the dc Zener current (|zt or Izk) is superimposed on {zt or Izk.
