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.
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.
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
Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
MECHANICAL DATA
Case: DO-214AC (SMA)
Molding compound meets UL 94 V-0 flammability rating
Base P/N-M3 - halogen-free, RoHS compliant, and
commercial grade
Terminals: Matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
M3 suffix meets JESD 201 class 1A whisker test
Polarity: For uni-directional types the band denotes
cathode end, no marking on bi-directional types
