Features
Mechanical Data
• Glass passivated chip junction
Case: Molded epoxy body over passivated junction
• Available in Unidirectional and Bidirectional
Epoxy meets UL 94V-0 flammability rating
• 1500 W peak pulse power capability with a
10/1000 µs waveform, repetitive rate (duty cycle):
0.01 %
• Excellent clamping capability
• Very fast response time
• Low incremental surge resistance
• Solder Dip 260 °C, 40 seconds
Terminals: Matte tin plated leads, solderable per
J-STD-002B and JESD22-B102D
E3 suffix for commercial grade, HE3 suffix for high
reliability grade (AEC Q101 qualified)
Polarity: For unidirectional types the color band
denotes cathode end, no marking on bidirectional
types
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
Devices for bidirection Applications
For bidirectional types, use C or CA suffix
(e.g. 1.5KE440CA).
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.
Electrical characteristics apply in both directions.
