SM15T Series
Vishay General Semiconductor
Surface Mount TRANSZORB(R) Transient Voltage Suppressors
FEATURES * Low profile package * Ideal for automated placement * Glass passivated chip junction * 1500 W peak pulse power capability with a 10/1000 s waveform * Available in uni-directional and bi-directional * Excellent clamping capability * Low inductance * Meets MSL level 1, per J-STD-020, LF maximum peak of 260 C * Solder dip 260 C, 40 s * Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC APPLICATION NOTES A 1500 W (SMC) device is normally selected when the threat of transients is from lightning induced transients, conducted via external leads or I/O lines. It is also used to protect against switching transients induced by large coils or industrial motors. Source impedance at component level in a system is usually high enough to limit the current within the peak pulse current (IPP) rating of this series. In an overstress condition, the failure mode is a short circuit. 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.
