MAXIMUM RATINGS
Operating Temperature: -65°C to +175°C
Storage Temperature: -65°C to +175°C
DC Power Dissipation: 1 watt @TL= 95°C
Power Derating: 12.5 mW / °C above TL= 95°C
Forward Voltage @ 200mA = 1.2 volts maximum
NOTE 1
No suffix = + 10% tolerance on nominal Zener voltage, suffix “A” signifies +5%, suffix “C”
signifies + 2%, suffix “D” signifies + 1%.
NOTE 2
Zener impedance is derived by superimposing on 1ZTA 60Hz rms a.c. current equal to
10% of 1ZT.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
