DESCRIPTION
This data sheet defines a series of dual zeners with a common anode. It
may be used for voltage regulation for two different lines to ground or as
a bidirectional voltage regulator between two lines. This product also
provides ESD protection per IEC 1000-4-2 and EFT protection per IEC
1000-4-4.
FEATURES
• Provides common-anode-dual zeners 3.3 to 200 volts
• Provides unidirectional zener-regulation for 2 lines to ground for
pins 1 to 3 and pins 2 to 3 or bidirectional regulation between
pins 1 and 2
• ESD non sensitive Human Body Model (HBM) >15,999 volts per
MIL-STD-750 Method 1020
• SOT-23 Packaging
MAXIMUM RATINGS
• Operating Temperatures: -55ºC to +150ºC
• Storage Temperature: -55ºC to +150ºC
• 250 mW maximum combined power (both legs)
• Thermal resistance RèJL = 400ºC/W
• Derate 250 mW power linearly from 50ºC to zero at 150ºC
