IEC 1000-4-2 (IEC801-2)
Ideal for EFT protection of data lines in accordance with
IEC 1000-4-4 (IEC801-4)
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 10/1000S
waveform, repetition rate(duty cycle) : 0.01% (300W above 78V)
Very fast response time
High temperature soldering guaranteed : 250/10 seconds
at terminals
Devices For Bidirectional Applications
Maximum Ratings And Electrical Characteristics
For bi-directional devices, use suffix C or CA (e.g. SMAJ10C, SMAJ10CA).
Electrical characteristics apply in both directions.
Case : JEDEC DO-214AC(SMA) molded plastic
over passivated chip
Terminals : Solder plated , solderable per
MIL-STD-750, method 2026
Polarity : For uni-directional types the band denotes
the cathode, which is positive with respect to the
anode under normal TVS operation
Mounting Position : Any
Weight : 0.002 ounce, 0.064 gram
Peak pulse power dissipation with a 10/1000S waveform (Note 1,2. Fig. 1)
Peak pulse current with a waveform (Note 1)
Typical thermal resistance, junction to lead
Typical thermal resistance, junction to ambient (Note 3)
