VF = 1.1V Max @IF = 200mA for 60V below types, VF = 1.4V Max @IF = 200mA for 60V above types

2. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)

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

3. ZENER VOLTAGE (VZ) MEASUREMENT

The zener voltage (V

Z) is tested under pulse condition. The measured VZ is guaranteed to be within specification with device

junction in thermal equilibrium.

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 I

Z(AC) = 0.1 IZ(DC) with AC frequency = 60Hz.

5. TEMPERATURE COEFFICIENT (θVZ)

Test conditions for temperature coefficient are as follows:

A. IZT = 7.5mA, T1 = 25℃, T2 = 125℃ (1N5221B through 1N5242B)

B. I

ZT = Rated IZT , T1 = 25℃, T2= 125℃ (1N5243B through 1N5281B)

Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
