TRANSZORB Transient Voltage Suppressors
FEATURES
Glass passivated chip junction
Available in uni-directional and bi-directional
1500 W peak pulse power capability with a
10/1000 s waveform, repetitive rate (duty cycle):
0.01 %
Excellent clamping capability
Very fast response time
Low incremental surge resistance
Solder Dip 260 °C, 40 seconds
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.
MECHANICAL DATA
Case: Molded epoxy body over passivated junction
Epoxy meets UL 94V-0 flammability rating
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 uni-directional types the color band
denotes cathode end, no marking on bi-directional
types
DEVICES FOR BI-DIRECTION APPLICATIONS
For
bi-directional
types,
use
C
or
CA
suffix
(e.g. 1.5KE440CA).
Electrical characteristics apply in both directions.
