DO-35

(DO-204AH)

APPLICATIONS / BENEFITS Regulates voltage over a broad operating current

Extensive selection from 2.4 to 200 V

Standard voltage tolerances are plus/minus 5% with B suffix, 10 % with A suffix identification

Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively

Flexible axial-lead mounting terminals Nonsensitive to ESD (MIL-STD-750 Method 1020) Minimal capacitance (see Figure 2)

suffix A; for 5% tolerance, add suffix B; for 2% tolerance add suffix C; for 1% tolerance, add suffix D.

NOTES:

1. Zener Impedance is derived from the 1 kHz ac voltage which results when an ac current having an rms value equal to 10% of

dc zener current (I ZT or I ZK) is superimposed on I ZT or I ZK. See MicroNote 202 for dynamic impedance variation with other

operating currents.

2. Voltage Measurements to be performed 20 seconds after application of the dc test current.

3. The maximum zener current I ZM shown is for the nominal voltages. The following formula can be used to determine the worst

case current for any tolerance device: P

I ZM =

V ZM

V ZM is the high end of the voltage tolerance specified and P is the rated power of the device.
