TOLERANCE AND TYPE NUMBER DESIGNATION  
2. The JEDEC type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.  
SPECIALS AVAILABLE INCLUDE:  
3. 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.  
ZENER VOLTAGE (V ) MEASUREMENT  
Z
4. Tak Cheong Electronics guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T ) at  
L
± 1°C, 3/8" from the diode body.  
30°C  
ZENER IMPEDANCE (Z ) DERIVATION  
Z
5. 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 (I or I ) is superimposed on I or I .  
ZT  
ZK  
ZT  
ZK  
SURGE CURRENT (I ) NON-REPETITIVE  
R
6. The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equiv-  
alent sine wave pulse of 1/120 second duration superimposed on the test current, I , per JEDEC registration; however, actual device  
ZT  
capability is as described in Figure 5 of the General Data DO-41 Glass.
