Features
Plastic package has Underwriters Laboratory Flammability
Classification 94V-0
Low profile package with built-in strain relief for surface
mounted applications
Glass passivated junction
Low incremental surge resistance, excellent clamping capability
1500W peak pulse power capability with a 10/1000us
waveform, repetition rate (duty cycle): 0.01%
Very fast response time
High temperature soldering guaranteed:
250oC/10 seconds at terminals
Mechanical Data
Case: JEDEC DO-214AB(SMC 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
Weight: 0.007oz., 0.21g
Devices for Bidirectional Applications
For bi-directional devices, use suffix CA (e.g. SMCJ10CA). Electrical characteristics apply in both directions.
