10. TOLERANCE AND TYPE NUMBER DESIGNATION (V

Z

)

The type numbers listed have a standard tolerance on the nominal zener voltage of

±5%.

11. ZENER VOLTAGE (V

Z

) MEASUREMENT

Nominal zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T

L

) at 30°C

±1°C

and 3/8” lead length.

12. ZENER IMPEDANCE (Z

Z

) DERIVATION

Z

ZT

and Z

ZK

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 I

Z(DC)

with AC frequency = 60Hz.

13. TEMPERATURE COEFFICIENT (θ

VZ

)

Test conditions for temperature coefficient are as follows:

A. I

ZT

= 7.5mA, T

1

= 25°C, T

2

= 125°C (1N5221B through 1N5242B)

B. I

ZT

= Rated I

ZT

, T

1

= 25°C, T

2

= 125°C (1N5243B through 1N5281B)

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

temperature.
