Transient Voltage Suppressors
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g. SM15T12CA).
Electrical characteristics apply in both directions.
APPLICATION NOTES
A 1500 W (SMC) device is normally selected when the threat
of transients is from lightning induced transients, conducted
via external leads or I/O lines. It is also used to protect
against switching transients induced by large coils or
industrial motors. Source impedance at component level in
a system is usually high enough to limit the current within the
peak pulse current (I
PP
) rating of this series. In an overstress
condition, the failure mode is a short circuit.
FEATURES
• Low profile package
• Ideal for automated placement
• Glass passivated chip junction
• Available in uni-directional and bi-directional
• 1500 W peak pulse power capability with a
10/1000 μs waveform
• Excellent clamping capability
• Low inductance
• Meets MSL level 1, per J-STD-020, LF maximum peak
of 260 °C
• AEC-Q101 qualified
• Material categorization: for definitions of compliance

TYPICAL APPLICATIONS
Use in sensitive electronics protection against voltage
transients induced by inductive load switching and lighting
on ICs, MOSFET, signal lines of sensor units for consumer,
computer, industrial, automotive, and telecommunication.
