MAXIMUM RATINGS
Operating Temperature: -65°C to +175°C
Storage Temperature: -65°C to +175°C
Power Derating: 10 mW / °C above TEC = +125°C
Forward Voltage: @ 200 mA: 1.1 Volts maximum
NOTE 1 “B” suffix = +5.0%, “A” suffix = +10%, no suffix = + 20%, "C" suffix = + 2% and "D" suffix = + 1%.
NOTE 2 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of1ZT.
NOTE 3 Nominal Zener voltage is measured with the device junction in thermal equilibrium at an
ambient temperature of 25°C + 3°C.
