DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional types, use C or CA suffix
(e.g. 1.5KE440CA).
Electrical characteristics apply in both directions.
FEATURES
• Glass passivated chip junction
• Available in uni-directional and bi-directional
• 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 s
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
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.
