1N4581AUR-1

The 1N4581AUR-1 is designed by the compensated devices incorporated company.

It has five features of 1N4581AUR-1. (1)It is available in JAN, JANTX, JANTXV and JANS per MIL-PRF-19500/452. (2)Temperature compensated zener reference diodes. (3)Leadless package for surface mount. (4)Low current operating range which would be from 0.5mA to 4.0mA. (5)Metallurgically bonded, double plug construction. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its operating temperature range would be from -65°C to 175°C. (2)Its storage temperature range would be from -65°C to 175°C. (3)Its DC power dissipation would be 500mW/°C. (4)Its power derating would be 4mW/°C above +50°C. (5)Its reverse leakage current would be 2uA at 25°C and Vr=3Vdc. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of 1N4581AUR-1 at 25°C unless otherwise specified are concluded as follow. (1)zener test current would be 4.0mA. (2)Its efficiency temperature coefficient would be 0.0005%/°C. (3)Its voltage temperature stability would have the maximum value of 24mV within -55°C to 100°C. (4)Its temperature range would be from 0°C to 75°C. (5)Its max dynamic zener impedance would be 25ohms.

And some design data of 1N4581AUR-1 are concluded as follow. (1)Its case is DO-213AA, hermetically sealed glass case. (MELF, SOD-80, LL34). (2)Its lead finish would be tin/lead. (3)Its polarity would mean diode to be operated with the banded (cathode) end positive. (4)Its mounting position could be any. (5)Its mounting surface selection would mean the axial coefficient of expansion (COE) of this device is approximately +6ppm/°C. The COE of the mounting surface system should be selected to provide A suitable match with this device. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
