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.
MECHANICAL DATA

SMA (DO-214AC)
Molding compound meets UL 94 V-0 flammability rating
Base P/N-E3 - RoHS-compliant and industrial grade
Base P/NHE3_X - RoHS-compliant and AEC-Q101 qualified
(“_X” denotes revision code e.g. A, B, .....)
Terminals:
matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3 suffix meets JESD 201 class 2 whisker test, HE3 suffix
meets JESD 201 class 2 whisker test
Polarity:
color band denotes cathode end
APPLICATION NOTES
• Respect thermal resistance (PCB Layout) - as the
temperature coefficient also contributes to the clamping
voltage
• Select minimum breakdown voltage, so you get
acceptable power dissipation and PCB tie point
temperature
• Devices with higher breakdown voltage will have a shorter
conduction time and will dissipate less power
• Clamping voltage is influenced by internal resistance -
design approximation is 7 V per 100 mA slope
• Keep temperature of TVS lower than TOPSwitch
®
as a
recommendation
• Maximum current is determined by the maximum T
J
and
can be higher than 300 mA
• Contact supplier for
current arrangements

• Minimum breakdown voltage can be customized for other
