Notes:

1.

The zener voltage (

2.

The device numCers listed have a standard tolerance on the nominal zener voltage of ±2%.

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 (

4.

For detailed information on price, availaCility and delivery of nominal zener voltages Cetween the voltages shown and tighter

voltage tolerances, contact your nearest Tak Cheong Electronics representative.
