Surface Mount TRANSZORB
®
Transient Voltage Suppressors
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 different clamping voltage/
current arrangements
• Minimum breakdown voltage can be customized for other
applications. Contact supplier
• TOPSwitch is a registered trademark of Power
Integrations, Inc.
FEATURES
• Glass passivated chip junction
• Available in uni-directional polarity only
• 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
• AEC-Q101 qualified
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
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.
