NOTE 1. TOLERANCE
The JEDEC type numbers shown indicate a tolerance of ±5%. For tighter tolerance devices
use suffixes “C” for ±2% and “D” for ±1%.
NOTE 2. TEMPERATURE COEFFICIENT (θVZ)
Test conditions for temperature coefficient are as follows:
a. IZT = 7.5 mA, T1 = 25°C,
a. T2 = 125°C (1N5221B through 1N5242B).
b. IZT = Rated IZT, T1 = 25°C,
a. T2 = 125°C (1N5243B through 1N5281B).
Device to be temperature stabilized with current applied prior to reading breakdown voltage
at the specified ambient temperature.
NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead
temperature of 30°C ±1°C and 3/8″ lead length.
NOTE 4. ZENER IMPEDANCE (ZZ) DERIVATION
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current
applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.

tive.
