NOTE 1. TOLERANCE AND TYPE NUMBER DESIGNATION
NOTE 4. ZENER IMPEDANCE (Z ) DERIVATION
Z
The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of
±5%. C for ±2%, D for ±1%.
The zener impedance is derived from the 60 cycle ac voltage, which results when an ac cur-
rent having an rms value equal to 10% of the dc zener current (I or I ) is superimposed
ZT
ZK
on I or I
ZT ZK
.
NOTE 2. SPECIALS AVAILABLE INCLUDE:
Nominal zener voltages between the voltages shown and tighter voltage tolerances.
For detailed information on price, availability, and delivery, contactyournearestMotorolarep-
resentative.
NOTE 5. SURGE CURRENT (i ) NON-REPETITIVE
r
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, re-
verse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second dura-
NOTE 3. ZENER VOLTAGE (V ) MEASUREMENT
Z
Motorola guarantees the zener voltage when measured at 90 seconds while maintaining the
tion superimposed on the test current, I , per JEDEC registration; however, actual device
capability is as described in Figure 5 of the General Data — DO-41 Glass.
ZT
lead temperature (T ) at 30°C ± 1°C, 3/8″ from the diode body.
