MECHANICAL DATA
Case: DO-214AC (SMA)
Molding compound meets UL 94 V-0 flammability rating
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g. P4SMA10CA).
Electrical characteristics apply in both directions.
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
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.
Polarity: For uni-directional types the band denotes
cathode end, no marking on bi-directional types
