TRANSZORB Transient Voltage Suppressors
FEATURES
Glass passivated chip junction
Available in Unidirectional and Bidirectional
500 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
and
telecommunication.
MECHANICAL DATA
Case: DO-204AC, molded epoxy over passivated chip
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 unidirectional types the color band
denotes cathode end, no marking on bidirectional
types
DO-204AC (DO-15)
DEVICES FOR BIDIRECTION APPLICATIONS
For
bidirectional
types,
use
C
or
CA
suffix
(e.g. SA5.0C, SA170CA).
Electrical characteristics apply in both directions.
