1N5226

The 1N5226 is designed as silicon planar zener diode. Standard zener voltage tolerance of the 1N5226 is +/-20%. Add suffix "A" for +/-10% tolerance and suffix "B" for +/-5% tolerance. Other tolerances, non standard and higher zener voltages upon request.

The absolute maximum ratings of the 1N5226 can be summarized as: (1) Its power dissipation at Ta=75°C would be 500mW. Valid provided that leads at a distance of 10mm from case are kept at ambient temperature. (2) Its junction temperature is 200°C. (3) Its storage temperature range is from -65°C to +200°C. (4) Its thermal resistance junction to ambient air would be max 0.3K.mW. Valid provided that leads at a distance of 10mm from case are kept at ambient temperature. (5) Its forward voltage at If=200mA would be max 1.1V.

The electrical characteristics of the 1N5226 are: (1) Its nominal zener voltage would be 3.3V. Measured under thermal equilibrium and DC test conditions. (2) Its test current Izt would be 20 mA. (3) Its maximum zener impedance would be 29 at Izt and would be 1600 at Izk=0.25 mA. 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 is superimposed on Izt or Izk. Zener impedance is measured at two points to insure a sharo knee on the breakdown curve and to eliminate unstable units (4) Its typical temperature coefficient would be -0.070 %/K. (5) Its maximum reverse leakage current would be 25uA at test voltage suffix A 0.95V and suffix B 1.0V. (6) Its maximum regulator current would be 138 mA. Valid provided that leads at a distance of 10mm from case are kept at ambient temperature. And so on.
