10. TOLERANCE AND TYPE NUMBER DESIGNATION (VZ)

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

11. ZENER VOLTAGE (VZ) MEASUREMENT

Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (TL) at 30°C

±1°C and 3/8” lead length.

12. 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.

13. TEMPERATURE COEFFICIENT (θVZ)

Test conditions for temperature coefficient are as follows:

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

B. IZT = Rated IZT, T1 = 25°C, T2 = 125°C (1N5243B through 1N5281B)

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

temperature.
