APPLICATION NOTES:

transiient voltage suppression from threats

generated by ESD for board levelload

switching components.

ecommended Pad Layout

The pad dimensions should be 0.010" longer than the

contact size in the lead axis. This allows a solder fillet

to form, see figure below. Contact factory for soldering

methods.

The wide leads assure a large surface contact

for good heat disipation, and a low resistance

path for surge current flow to ground.

This series is designed to optimize board

space and for use with surface mount technology

automated assembly equipment.

They can be easily mounted on printed circuit

boards and ceramic substrates to protect

sensitive components from transient voltage

damage.
