FEATURES
z Plastic package has underwriters laboratory flammability classification 94V-0
z Optimized for LAN protection applications
z Low profile package with built-in strain relief for surface mounted applications
z Low incremental surge resistance, excellent clamping capability
z 400W peak pulse power capability with a 10/1000¦Ìs wave
z form, repetition rate (duty cycle): 0.01% (300W above 78V)
z Very fast response time
z High temperature soldering guaranteed: 250° C/ 10 seconds at terminals
MECHANICAL DATA
z Case: JEDEC DO-214AC molded plastic over passivated chip
z Terminals: solder plated, solderable per MIL-STD-750, method 2026
z Polarity: for uni-directional types the color band denotes the cathode, which is postitive with respect to the
anode under normal TVS operation
z Mounting position: any Weight: 0.002 ounces, 0.064 grams
Devices for Bidirectional Applications
For bi-directional devices, use suffix C or CA (e.g. SMAJ10C, SMAJ10CA). Electrical characteristics apply in both
directions.
