1n5221

1N5221 thru 1N5281
Zener Voltage Range: 2.4 to 200 Volts
Features
Silicon Planar Power Zener Diodes.
Standard Zener voltage tolerance is ±5% with a “B” suffix,
and ±10% with a “A” suffix . Other tolerances are available
upon request.
These diodes are also available in Mini-MELF case with the type
designation ZMM5225...ZMM5267.

Notes:
1. The Zener Impedance is derived from the 1 KHZ 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.
2. Valid provided that leads at a distance of 10 mm from case are kept at ambient temperature.
3. Measured with device junction in thermal equilibrium.
