Also available in 2% and 1% tolerance, suffix C and D respectively. Vz is measured with the diode in thermal equilibrium in 25℃ still air. 2) Zener impedance is derived by superimposing on IZT, a 60Hz rms a.c. current equal to 10% of IZT (25uA a.c.) 3) Based upon 400 mW maximum power dissipation at 75℃ lead temperature, allowance has been made for the higher voltage associated with operation at higher currents. http://www.luguang.cn mail:[email protected]
