2. TOLERANCE AND TYPE NUMBER DESIGNATION (V_Z)

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

3. 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.

4. ZENER IMPEDANCE (Z_Z) DERIVATION

Z_ZTand Z_ZKare 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.

5. TEMPERATURE COEFFICIENT (θ_VZ

)

Test conditions for temperature coefficient are as follows:

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

B. I_ZT= Rated I_ZT, 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.
