1N5344B - 1N5388B
5W ZENER DIODE
Notes: 1. Nominal Zener Voltage (V
Z
) is read with the device in standard test clips with 3/8- to 1/2-inch spacing between clip and case
of the diode. Before reading, the diode is allowed to stabilize for a period of 40 c17710 milliseconds at 25c176C +8, -2c176C.
2. The Zener Impedance (Z
Z
or Z
ZK
) is derived from the 60 Hz 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 on I
ZT
or I
ZK,
respectively.
3. The Surge Current (I
ZSM
) is specified as the maximum peak of a nonrecurrent sine wave of 8.3 milliseconds duration.
4. Voltage regulation (c68V
Z
) is the difference between the voltage measured at 10% and 50% of I
ZM
.
