Surface Mount TRANSZORB® Transient Voltage Supressors
SM6T Series
Vishay General Semiconductor
New Product
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g. SM6T12CA).
Electrical characteristics apply in both directions.
FEATURES
• Low profile package
• Ideal for automated placement
• Glass passivated chip junction
• Available in uni-directional and bi-directional
• 600 W peak pulse power capability with a 10/1000 μs
waveform, repetitive rate (duty cycle): 0.01 %
• Excellent clamping capability
• Low inductance
• Meets MSL level 1, per J-STD-020, LF maximum peak of
260 °C
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
•Halogen-free according to IEC 61249-2-21 definition
TYPICAL APPLCIATIONS
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
