VF Forward Voltage = 1.1 V Maximum @ IF = 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 v oltages 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 (IZT or IZK) is superimposed to IZT or IZK.

Packaging Description:

LL34 parts are shipped in tape and reel.

The c arrier ta pe is mad e from a dis sipati ve

(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
