= 200 mA for all types
Notes:
1. The type numbers listed have zener voltage min/max limits as shown and have a standard tolerance on the nominal zener
voltage.
2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tolerances, contact your nearest Tak Cheong Electronics representative.
3. 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
ZT
or
I
ZK
) is superimposed to
I
ZT
or
I
ZK.

Axial-Lead Tape Packaging Standards
This axial-lead component’s packaging requirements use in automatic testing and assembly equipment. And this standard practices for
lead-tape packaging of axial-lead components meets the requirements of EIA Standard RS-296-D “Lead-taping of Components on Axial
Lead Configuration for Automatic Insertion”.
