Low profile package with built-in strain relief for
surface mounted applications
Glass passivated junction
Low incremental surge resistance, excellent clamping
capability
400W peak pulse power capability with a 10/1000µs wave-
form, repetition rate (duty cycle): 0.01% (300W above 78V)
Very fast response time
High temperature soldering guaranteed: 250°C/10
seconds at terminals
ME CHANI CAL DATA
Case:JEDEC DO-214AC molded plastic over passivated
chip

method 2026
Polarity: foruni-directional types the color band denotes
the cathode, which is postitive with respect to the
anode under normal TVS operation
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.
Operating junction and storage temperature range TJ, TSTG -55---+150
