= 200 mA for all types
Notes:
1. The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of ±5% in
Blue marking, suffix A=±10% in Brown marking, C= ±2% in Orange marking and D = ±1% in Yellow marking.
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.

LL-34 Packaging Outline
Label
Packaging Description:
LL34 parts are shipped in tape and reel.
The carrier tape is made from a dissipative
(carton filled) polycarbonate resin. The
cover tape is a multiplayer film (Heat
Activated Adhesive in nature) primarily
composed of polyester film, adhesive layer,
sealant, and anti-static sprayed agent.
These reeled parts in standard option are
shipped with 2,500 units per 7” or 178mm
diameter reel. The reels are blue in color
and made of recyclable plastic. Other
option comes in 10,000 units per 13” or
330mm diameter reel
