glass case. (MELF, LL41)
LEAD FINISH:
Tin / Lead
THERMAL RESISTANCE: (R
OJEC): 50
˚C/W maximum at L = 0 inch
THERMAL IMPEDANCE: (Z
OJX): 15
˚C/W maximum
POLARITY:
Diode to be operated with the
banded (cathode) end positive with
respect to the opposite end.

NOTE 3
No suffix signifies + 20%. “A” Suffix signifies + 10%, “B” Suffix signifies + 5%. "C" suffix
signifies + 2% and "B" suffix signifies + 1%.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C +3°C.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT
