TRANSIENT VOLTAGE SUPPRESSOR
SCOTTSDALE DIVISION
DESCRIPTION
This Transient Voltage Suppressor (TVS) series is an economical molded
surface mount package with very low thermal resistance due to its unique
axial subassembly. It is used for automotive applications and others to
protect voltage sensitive components from destructive or partial degradation.
They have a peak pulse power rating of 400 watts for 1 ms as depicted in
Figures 1 and 2. The package is configured for easy pick and place onto PC
Boards for automated handling. The J-bend terminations also provide stress
relief for use on a variety of PC Board materials.
