Note: 1.The type numbers listed have zener voltage min/max as shown. Device tolerance of 2% are indicated by a "B"
instead of a "C". Zener voltage is measured with the device junction in thermal equilibrium at the lead temperature
of 301 and 3/8 lead length.
2.Z
ZT
and Z
ZK
are measured by dividing the ac voltage drop across the device by the ac current applied. The specified
limits are for I
Z(ac)
=0.1I
Z(dc)
with the ac frequency = 1k Hz.
3.This data was calculated using nominal voltages. The maximum current handling capability on a worse case basis is
limited by the actual zener voltage at the operating point and the powered derating curve.
