TRANSIENT VOLTAGE SUPPRESSORS
Features
●
For surface mounted applications in
order to optimize board space
Low profile space
Glass passivated chip
Low inductance
Excellent clamping capability
Very fast response time
Typical I
D
less than 1µA at V
WM
400 W peak pulse power capability
with a 10/1000 µs waveform
Component in accordance to
RoHS 2002/95/1 and WEEE 2002/96/EC

Mechanical Date
●
Case: JEDEC DO-214AC molded plastic
over passivated chip
Terminals: Solder plated, solderable per
MIL-STD-750 Method 2026
Polarity: For uni-directional types the band
by laser denotes the cathode, which is
positive with respect to the anode under
normal TVS operation
●
●
Devices for Bidirectional Applications
●
For bi-directional devices, use suffix C or CA (e.g.SMAJ10C, SMAJ10CA).
Electrical characteristics apply in both directions.
