0.01 %
Excellent clamping capability
Very fast response time
Low incremental surge resistance
Meets MSL level 1, per J-STD-020C
AEC-Q101 qualified
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
Mechanical Data
Case: Molded plastic body over passivated junction
Epoxy meets UL-94V-0 Flammability rating
Terminals: Matte tin plated (E3 Suffix) leads, solder-
able per J-STD-002B and MIL-STD-750, Method
2026
Polarity: For unidirectional types the color band
denotes cathode end, no marking on bidirectional
types
Devices for bidirection Applications
For bidirectional types, use C or CA suffix for types
(e.g. 1.5KE440CA).
Electrical characteristics apply in both directions.
