1. TOLERANCE AND TYPE NUMBER DESIGNATION
Tolerance designation – the type numbers listed have zener voltage min/max limits as shown. Device tolerance of ±2% are
indicated by a “B” instead of a “C”.
2. SPECIALS AVAILABLE INCLUDE
Nominal zener voltages between the voltages shown and tighter voltage tolerances. For detailed information on price,
availability and delivery, contact your nearest Tak Cheong representative.
3. ZENER VOLTAGE (VZ) MEASUREMENT
VZ is measured after the test current has been applied to 40 ±10msec., while maintaining the lead temperature (TL) at 30°C
±1°C and 3/8” lead length.
4. ZENER IMPEDANCE (ZZ) DERIVATION
The zener impedance is derived from the 60 cycle AC voltage, which results when an AC current having an RMS value
equal to 10% of the DC zener current (IZT or IZK) is superimposed on IZT or IZK
.
5. SURGE CURRENT (Ir) NON-REPETITIVE
The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of ½ square
wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current IZT per JEDEC registration;
however, actual device capability is as described in figure 5 of the General Data DO-41 Glass.
