• Excellent clamping capability
• Very fast response time
• Low incremental surge resistance
• Meets MSL level 1, per J-STD-020, LF maximum
peak of 260 °C
DO-214AC (SMA)
• Solder dip 260 °C, 40 s
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC

• Respect thermal resistance (PCB Layout) - as the
temperature coefficient also contributes to the
clamping voltage
IFSM
TJ max.
150 °C
• Select minimum breakdown voltage, so you get
acceptable power dissipation and PCB tie point
temperature
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 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
MECHANICAL DATA
Case: DO-214AC (SMA)
Molding compound meets UL 94 V-0 flammability
rating
as a recommendation
• Maximum current is determined by the maximum
T and can be higher than 300 mA
J
Base P/N-E3 - RoHS compliant, commercial grade
Base P/NHE3 - RoHS compliant, high reliability/
automotive grade (AEC Q101 qualified)
• Contact supplier for different clamping voltage/
current arrangements
• Minimum breakdown voltage can be customized for
other applications. Contact supplier
Terminals: Matte tin plated leads, solderable per
J-STD-002 and JESD22-B102
• TOPSwitch is a registered trademark of Power
Integrations, Inc.
E3 suffix meets JESD 201 class 1A whisker test, HE3
