Surface Mount TRANSZORB Transient Voltage Suppressors
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
Solder dip 260 °C, 40 s
Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
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
TJ 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

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.
