1N4752 CHENYI [Shanghai Lunsure Electronic Tech], 1N4752 Datasheet - Page 2

• Manufacturer Part Number: 1N4752
• Description: 1W SILICON PLANAR ZENER DIODES
• Manufacturer: CHENYI [Shanghai Lunsure Electronic Tech]

Notes:1) The Zener impedance is derived from the 1KHz AC voltage which results when an AC current having an RMS calue equal to 10% of the Zener

Type
2)Valid provided that electrodes at a distance of 10mm from case are kept at ambient temperature
3)Measured under thermal equilibriun and DC test conditions.
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.
