TransFeed
AVX Multilayer Ceramic Transient Voltage Suppressors
TVS Protection and EMI Attenuation in a Single Chip
GENERAL DESCRIPTION
Schematic Diagram
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 market 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 advantages: (1) faster “turn-on” time. Calculated response times
of <200 pSec are not unusual with this device, and measured 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, resulting in EMI filtering over a much broader frequency spectrum. 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.

PERFORMANCE CHARACTERISTICS
FEEDTHRU VARISTORS
AVX Multilayer Feedthru Varistors (MLVF) are an ideal choice
for system designers with transient strike and broadband
EMI/RFI concerns.
Feedthru Varistors utilize a ZnO varistor material and the
electrode pattern of a feedthru capacitor. This combination
allows the package advantage of the feedthru and material
advantages of the ZnO dielectric to be optimized.
ZnO MLV Feedthrus exhibit electrical and physical advantages
over standard ZnO MLVs. Among them are:
1. Faster Turn on Time
2. Broadband EMI attenuation
3. Small size (relative to discrete MLV and EMI filter schemes)
The electrical model for a ZnO MLV and a ZnO Feedthru MLV
are shown below. The key difference in the model for
the Feedthru is a transformation in parallel to series inductance. The added series inductance helps lower the injected
transient peak current (by 2πfL) resulting in an additional benefit of a lower clamping voltage. The lowered parallel inductance decreases the turn on time for the varistor to <250ps.
