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.
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 (SMC)
Molding compound meets UL 94 V-0 flammability rating
Base P/N-E3 - RoHS compliant and commercial grade
Base P/NHE3 - RoHS compliant and AEC-Q101 qualified
Terminals:
Matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3 suffix meets JESD 201 class 1A whisker test, HE3 suffix
meets JESD 201 class 2 whisker test
Polarity:
For uni-directional types the band denotes
cathode end, no marking on bi-directional types
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.
