APPLICATION NOTES
A 1500 W (SMCJ) 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.
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g. SM15T12CA).
Electrical characteristics apply in both directions.
MECHANICAL DATA
Case:
DO-214AB (SMCJ)
Molding compound meets UL 94 V-0 flammability rating
Base P/N-M3 - halogen-free, RoHS-compliant, and
commercial grade
Terminals:
Matte tin plated leads, solderable
J-STD-002 and JESD22-B102
M3 suffix meets JESD 201 class 2 whisker test
per
TYPICAL APPLCIATIONS
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, and telecommunication.
Polarity:
For uni-directional types the band denotes
cathode end, no marking on bi-directional types
