NOTE 1 Zener impedance is derived by superimposing on lZTA 60Hz rms a.c. current

equal to 10% of lZT.

NOTE 2 The maximum allowable change observed over the entire temperature range

i.e.,the diode voltage will not exceed the specified mV at any discrete

temperature between the established limits, per JEDEC standard No.5.

NOTE 3 Zener voltage range equals 19.2 volts +

5%.

• 19.2 VOLT NOMINAL ZENER VOLTAGE + 5%

• TEMPERATURE COMPENSATED ZENER REFERENCE DIODES

• LOW NOISE

• METALLURGICALLY BONDED

• DOUBLE PLUG CONSTRUCTION
