600 Wallts
Mechanical Data
Case: JEDEC DO-214AA(SMB J-Bend) molded plastic over
passivated junction
Terminals: Solder plated, solderable per MIL-STD-750,
Method 2026
Polarity: For unidirectional types the band denotes the cathode,
which is positive with respect to the anode under normal TVS
operation
