DO-35
(DO-204AH)
APPLICATIONS / BENEFITS
Regulates voltage over a broad operating
current and temperature range
Standard voltage tolerances are plus/minus 5%
with A suffix identification and 10 % with no suffix Tight tolerances available in plus or minus 2%
or 1% with C or D suffix respectively
Flexible axial-lead mounting terminals
Nonsensitive to ESD per MIL-STD-750 Method
Minimal capacitance (see Figure 3)
NOTE 1: Standard tolerance on JEDEC types shown is +/- 10%. Suffix letter A denotes +/- 5% tolerance; suffix
letter C denotes +/- 2%; and suffix letter D denotes +/- 1% tolerance.
NOTE 2: Voltage measurements to be performed 20 seconds after application of dc test current.
NOTE 3: Zener impedance derived by superimposing on I ZT , a 60 cps, rms ac current equal to 10% I ZT (2mA ac). See MicroNote 202 for typical zener Impedance variation with different operating currents.
NOTE 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 400 mW.
