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

(2mA ac)
4. Allowance has been made for the increase in V

and for the increase in junction temperature as the unit approaches thermal
equilibrium at the power dissipation of 400mW.
