description
These high voltage dual symmetrical transient
SD3XAA
G
voltage suppressor devices are designed to
protect telecommunication applications with
ground backed ringing against transients caused
by lightning strikes and a.c. power lines. Offered
in five voltage variants to meet battery and
protection requirements they are guaranteed to
suppress and withstand the listed international
lightning surges in both polarities. Transients are
initially clipped by breakdown clamping until the
voltage rises to the breakover level, which
Terminals T, R and G correspond to the
alternative line designators of A, B and C
causes the device to crowbar. The high crowbar
holding current prevents d.c. latchup as the
current subsides.
These monolithic protection devices are
fabricated in ion-implanted planar structures to
