N0TES:
(1) V(BR) measured after IT applied f0r 300µs IT=square wave pulse or equivalent
(2) Surge current waveform per Fig. 3 and derate per Fig. 2
(3) For bidirectional types having VWM of 10 Volts and less, the ID limit is doubled
(4) All terms and symbols are consistent with ANSI/IEEE C62.35
APPLICATION N0TES
These surface mountable packages are designed specifically for transient voltage suppression. The wide leads assure a large surface
contact for good heat dissipation, and a low resistance path for surge current flow to ground. These high speed transient voltage
suppressors can be used to effectively protect sensitive components such as integrated circuits and MOS devices.
A 600W (SMB) device is normally selected when the threat of transients is from lightening-induced transients conducted via external
leads or 1/0 lines. It is also used to protect against switching transients induced by large coils or industrial motors.
System impedance at component level in a system is usually high enough to limit the current to within the peak pulse current (I PP)
rating of this series.
RECOMMENDED PAD SIZES
The pad dimensions should be 0.010” (0.25mm) longer than the contact size, in the lead axis.
This allows a solder fillet to form, see Fig. below. Contact factory for soldering methods.
