LM299H

The LM299 series are precision, temperature-stabilized monolithic zeners offering temperature coefficients a factor of ten better than high quality reference zeners.The LM299H belongs to LM299 series.

Features of the LM299H are:(1)guaranteed 0.0001%/  temperature coefficient;(2)low dynamic impedance is 0.5;(3)initial tolerance on breakdown voltage is 2%;(4)sharp breakdown at 400 A;(5)wide operating current is 500 A to 10 mA;(6)wide supply range for temperature stabilizer;(7)guaranteed low noise;(8)low power for stabilization is 300 mW at 25;(9)long term stability is 20 ppm;(10)proven reliability, low-stress packaging in TO-46 integrated-circuit hermetic package, for low hysteresis after thermal cycling. 33 million hours MTBF at TA =+25 (TJ = +86);(11)certified long term stability available;(12)MIL-STD-883 compliant.

The absolute maximum ratings of the LM299H can be summarized as:(1):the temperature stabilizer voltage is 40V;(2):the reverse breakdown current is 20 mA;(3):the forward current is 1mA;(4):the reference to substrate voltage V(RS) is 40V and -0.1V;(5):the operating temperature range is −25 to +85;(6):the storage temperature range is −55 to +150;(7):the soldering information TO-92 package (10 sec.) is +260;(8):the soldering information TO-46 package (10 sec.) is +300.
