Devices for Bidirectional Applications
For bi-directional devices, use suffix CA (e.g. 1.5SMC10CA). Electrical characteristics apply in both directions.
Maximum Ratings & Thermal Characteristics Ratings at 25°C ambient temperature unless otherwise specified.

Mechanical Data
Case: JEDEC DO-214AB (SMC) molded plastic over
passivated junction
Terminals: Solder plated, solderable per MIL-STD-750,
Method 2026. High temperature soldering: 250°C/10
seconds at terminals.
Polarity: For uni-directional types the band denotes the
cathode, which is positive with respect to the anode
under normal TVS operation.
