Forward Voltage = 900mV Maximum @ I

F

= 10 mA for all types

Notes:

1.

The Zener Voltage (V

Z

) is tested under pulse condition of 10mS.

2.

The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%.

3.

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.

4.

The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an rm s value equal to

10% of the dc zener current (I

ZT

or I

ZK

) is superimposed to I

ZT

or I

ZK.
