Surface Mount TRANSZORB® Transient Voltage Suppressors
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g. P4SMA10CA).
Electrical characteristics apply in both directions.
FEATURES
• Low profile package
• Ideal for automated placement
• Glass passivated chip junction
• Available in uni-directional and bi-directional
• 400 W peak pulse power capability with a
10/1000 μs waveform, repetitive rate
(duty cycle): 0.01 % (300 W above 91 V)
• 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, and telecommunication.
