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