Mechanical Data
Features
• Low profile package with built-in strain relief for
surface mounted applications
Case: JEDEC DO-214AB (SMC) molded plastic over
passivated junction
• Glass passivated junction
• Low inductance
Terminals: Solder plated, solderable per MIL-STD-750,
Method 2026
• Excellent clamping capability
Polarity: For uni-directional types the band denotes the
cathode, which is positive with respect to the anode
under normal TVS operation
