Features
Dual Silicon Planar Zener Diodes with Common
Cathode or Common Anode configurations.
Dual package provides for Bidirectional or
separate unidirectional configurations.
The dual configurations protect two separate lines
with only one device.
Peak Power: 40 watts @1ms (Bidirectional) .
High temperature Soldering Guaranteed:
230C for 10 seconds.
Ideal for ESD Protection.
For bidirectional operation, circuit connected to
pins 1 and 2. For unidirectional operation, circuit
connected to pins 1 and 3 or pins 2 and 3.
