N0TES:
(1) V
(BR)
measured after I
T
applied for 300
s square wave pulse or equivalent
(2) Surge current waveform per Fig. 3 and derate per Fig. 2
(3) For bi-directional types having V
WM
of 10 Volts and less, the I
D
limit is doubled
(4) For the bi-directional SMCG/SMCJ5.0CA, the maximum V
(BR)
is 7.25 Volts
(5) 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 sur-
face 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 1500W (SMC) device is normally selected when the threat of transients is from lightning-induced transients conducted via external
leads or I/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 figure below. Contact factory for soldering methods.
