• 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:
230˚C 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.
