NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
The “B” suffix type numbers listed are
±
5% tolerance of nominal VZ.
NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambi-
ent temperature of 25
°
C.
NOTE 3. ZENER IMPEDANCE (ZZ) DERIVATIO
N
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 (IZT) is superimposed on IZT.
NOTE 4. REVERSE LEAKAGE CURRENT IR
Reverse leakage currents are guaranteed and are measured at VR as shown on the table.
NOTE 5. MAXIMUM REGULATOR CURRENT (IZM)
The maximum current shown is based on the maximum voltage of a
±
5% type unit, therefore,
it applies only to the “B” suffix device. The actual IZM for any device may not exceed the value
of 400 milliwatts divided by the actual VZ of the device.
NOTE 6. MAXIMUM REGULATION FACTOR (
VZ)
VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device
junction in thermal equilibrium.
NOTE 7. SPECIAL SELECTORS AVAILABLE INCLUDE:
A) Tighter voltage tolerances. Contact your nearest Motorola representative for more infor-
mation.
