UN Semiconducctor INC
Description
The SM4Z series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Working Voltage: 15 to 43 V
They provide a clamping voltage lower than the avalanche voltage. Therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create very high capacity protection solutions.
FEATUREs
◆ Peak power dissipation 4400W @10 x 1000 us Pulse.
◆ Glass passivated chip junction .
◆ Low leakage
◆ Excellent clamping capability
◆ Available in uni-directional polarity only
◆ TJ = 175 ° C capability suitable for high reliability and automotive requirement
◆ Meet with ISO 7637-2,ISO 16750,etc
◆ Halogen free and RoHS compliant
APPLICATIONs
Use in sensitive electronics protection against voltage transients induced by inductive load switching and lighting, especially for automotive load dump protection application
