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% lZT (2mA ac)
4. Allowance has been made for the increase in VZ due to ZZ and for the increase in junction temperature as the unit approaches thermal
equilibrium at the power dissipation of 400mW.
