Small Signal Zener Diodes, Dual
MMBZ27VDA-V
Vishay Semiconductors
Features
• Dual Silicon Planar Zener Diodes with
Common Anode configurations
• Dual package provides for Bidirectional or ^e3
separate unidirectional configurations
• The dual configurations protect two separate lines
with only one device
• Peak Power: 40 W at 1 ms (Bidirectional)
• 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
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
