1500 Watt Low Capacitance
Transient Voltage Suppressor
DESCRIPTION
This Transient Voltage Suppressor (TVS) product family includes a rectifier diode element in
series and in an opposite direction. This allows it to achieve low capacitance performance
below 100 pF (see
figure 2).
The low level of TVS capacitance may be used for protecting
higher frequency applications in inductive switching environments or electrical systems
involving secondary lightning effects per IEC61000-4-5 as well as RTCA/DO-160 or ARINC
429 for airborne avionics. With virtually instantaneous response, they also protect from ESD
and EFT per IEC61000-4-2 and IEC61000-4-4. If bipolar transient capability is required, two
of these low capacitance TVS devices may be used in parallel in opposite directions (anti-
parallel) for complete ac protection as shown in
figure 4.

Notes:
1. When mounted on FR4 PC board with 4 mm

copper pads (1 oz) and track width 1 mm, length 25 mm.
2. At 10/1000
µs
with repetition rate of 0.01% or less (see
figure 1).
3. At 3/8 inch (10 mm) from body. TVS devices are not typically used for dc power dissipation and are instead operated at or less than their
rated standoff voltage (V
WM
) except for transients that briefly drive the device into avalanche breakdown (V
BR
to V
C
region). Also see
figure 4
for further protection details in rated peak pulse power for unidirectional and bidirectional configurations respectively.

Definition
Breakdown Current: The current used for measuring breakdown voltage V
(BR)
.
o
Breakdown Voltage: This is the breakdown voltage the device will exhibit at 25 C.
Rated Working Standoff Voltage: The maximum peak voltage that can be applied over the operating temperature range.
Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the peak pulse
current in a one millisecond time interval. The peak pulse voltage is the combination of voltage rise due to both the
series resistance and thermal rise and positive temperature coefficient
