• Manufacturer Part Number: 1N5221THRU1N5281
• Description: 0.5W SILICON PLANAR ZENER DIODES
• Manufacturer: Shanghai Lunsure Electronic Tech

(1)The Zener impedance is derived from the 60Hz Ac voltage which results when an AC current having an RMS value equal to 10% of
(2)Valid provided that leads at a distance of 8mm from case are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
1N5250…1N5281 SILICON PLANAR ZENER DIODES
the Zener current (IZT) is suprimposed 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.
