NOTES:

(1) V_(BR)measured after I_Tapplied for 300µs square wave pulse or equivalent

(2) Surge current waveform per Fig. 3 and derate per Fig. 2

(3) For bi-directional types having V_WMof 10 Volts and less, the I_Dlimit is doubled

(4) For the bi-directional SMAJ5.0CA, the maximum V_(BR)is 7.25V.

(5) All terms and symbols are consistent with ANSI/IEEE C62.35

APPLICATION NOTES

This device is designed specifically for transient voltage suppression from

threats generated by ESD for board level load switching components.

RECOMMENDED PAD LAYOUT

The pad dimensions should be 0.010” (2.5mm) 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 dissipation,

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.
