Features
Mechanical Data
• Underwriters Laboratory Recognition under UL standard
for safety 497B: Isolated Loop Circuit Protection
Case: JEDEC DO-215AA molded plastic over
passivated junction
Terminals: Solder plated, solderable per
MIL-STD-750, Method 2026
• Low profile package with built-in strain relief for surface
mounted applications
Polarity: For unidirectional types the band denotes the
cathode, which is positive with respect to the anode
under normal TVS operation
