“Crow Bar” Protection
To protect sensitive telecommunications
circuitry, Crydom Thyristors (SiBOD
™
Breakover Devices) “crow bar” potentially
dangerous transients – switching them to
ground and dissipating the voltage to
zero. This approach can handle more
energy than TVS diode “clamping.”

Our surface-mount components are
placed in embossed cavities of anti-
static/conductive carrier tape and
sealed with a cover tape. The taped
devices are supplied in reels in protec-
tive boxes. The standard Crydom lead-
tape packaging of surface-mount com-
ponents follow the requirements of EIA
481-1, shown below:
• Cover Tape: This will not extend over
the edge of the carrier tape or extend
over any part of the sprocket holes.
• Carrier Tape: This will release from the
reel hub as the last portion of the tape
unwinds from the reel without damage
to the carrier tape and with the compo-
nents remaining in the cavities.
• Leader Tape: A minimum length of
300mm leader (and trailer) of tape will
be provided before the first (and after
the last) component on the reel, with
a minimum of forty empty component
carrier pockets covered with tape.
