DO-35

(DO-204AH)

APPLICATIONS / BENEFITS Regulates voltage over a broad operating

Guaranteed voltage regulation (?V Z)from I ZL to I

Voltage selection from 3.3 to 33 V

Standard voltage tolerances are plus/minus 5%

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 1020

1. TOLERANCE AND VOLTAGE DESIGNATION –

The JEDEC type numbers shown are +/-20% with guaranteed limits for only V Z, I R, and V F. Units with A suffix are +/-10% with

guaranteed limits for V Z, I R, and V F. Units with guaranteed limits for all six parameters are indicated by a B suffix for +/-5.0% units,

C suffix for +/-2.0% and

D suffix for +/-1.0%.

2. ZENER VOLTAGE (V Z) MEASUREMENT –

Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25o C.

3. ZENER IMPEDANCE (Z Z) MEASUREMENT –

The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (I ZT) is superimposed on I ZT.

4. REVERSE LEAKAGE CURRENT (I R) –

Reverse leakage currents are guaranteed and are measured at V R as shown on the table.

5. MAXIMUM REGULATOR CURRENT (I ZM) –

The maximum current shown is as shown in MIL-PRF-19500/437.

6. MAXIMUM REGULATION FACTOR (?V Z) –

?V Z is the maximum difference between V Z at I ZT and V Z at I ZL measured with the device junction in thermal equilibrium.

Noise density, (N D ) is specified in microvolts rms per square-root-hertz (μV/ √Hz). Actual measurement is performed using a 1 kHz to 3 kHz frequency bandpass

filter with a constant Zener test current (I ZT ) at 25o

C ambient temperature.
