Notes:

1. Suffix letter A denotes ±5% tolerance, suffix C denotes ±2% tolerance, & suffix D denotes ±1% tolerance.

2. Voltage measurements to be performed 20 seconds after application of dc current.

3. Zener impedance derived by superimposing on l_ZT, a 60cps, rms ac current equal to 10% l_ZT(2mA ac)

4. Allowance has been made for the increase in V_Zdue to Z_Zand for the increase in junction temperature as the unit approaches thermal

equilibrium at the power dissipation of 400mW.
