TransFeed
AVX Multilayer Ceramic Transient Voltage Suppressors
TVS Protection and EMI Attenuation in a Single 0805 Chip - V2F Series
GENERAL DESCRIPTION
AVX has combined the best electrical characteristics of its
TransGuard Transient Voltage Suppressors (TVS) and its
Feedthru Capacitors into a single chip for state-of-the-art
overvoltage circuit protection and EMI reduction over a
broad range of frequencies. This unique combination of
multilayer ceramic construction in a feedthru configuration
gives the circuit designer a single 0805 chip that responds
to transient events faster than any TVS device on the mar-
ket today, and provides significant EMI attenuation when in
the off-state.
The reduction in parallel inductance, typical of the feedthru
chip construction when compared to the construction of
standard TVS or ceramic capacitor chips, gives the
TransFeed product two very important electrical advan-
tages: (1) faster “turn-on” time. Calculated response times
of <200 pSec are not unusual with this device, and mea-
sured response times range from 200 – 250 pSec. The
TransFeed “turn-on” characteristic is less than half that of
an equivalent TransGuard part — and TransGuards clamp
transient voltages faster than any other bipolar TVS solution
such as diodes; (2) the second electrical advantage of
lower parallel inductance, coupled with optimal series
inductance, is the enhanced attenuation characteristics of
the TransFeed product. Not only is there significantly
greater attenuation at a higher self-resonance frequency,

but the roll-off characteristic becomes much flatter, result-
ing in EMI filtering over a much broader frequency spec-
trum. Typical applications include filtering/protection on
Microcontroller I/O Lines, Interface I/O Lines, Power Line
Conditioning and Power Regulation.
Where designers are concerned with both transient voltage
protection and EMI attenuation, either due to the electrical
performance of their circuits or due to required compliance
to specific EMC regulations, the TransFeed product is an
ideal choice.
