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 (VZ) 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 IZ(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. IZT = 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.
