DESCRIPTION APPEARANCE
This Transient Voltage Suppressor (TVS) product family includes a rectifier
diode element in series and opposite direction 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-160D 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.

MAXIMUM RAT ING S MECHANICAL AND PACKAGING
• 1500 Watts for 10/1000 μs with repetition rate of 0.01% or
less* at lead temperature (TL) 25oC (See Figs. 1, 2, & 4)
• Operating & Storage Temperatures: -65o to +150oC
• Thermal Resistance: 22ºC/W junction to lead at 3/8
inch (10 mm) from body, or 82ºC/W junction to ambient
when mounted on FR4 PC board with 4 mm2 copper
pads (1oz) and track width 1 mm, length 25 mm
• Steady-State Power dissipation*: 5 watts at TL = 40oC,
or 1.52 watts at TA = 25ºC when mounted on FR4 PC
board described for thermal resistance
• Solder Temperatures: 260 o C for 10 s (maximum)
• CASE: Void-free transfer molded thermosetting
epoxy body meeting UL94V-0
• TERMINATIONS: Tin-lead or RoHS Compliant
annealed matte-Tin plating readily solderable per
MIL-STD-750 method 2026
• POLARITY: Cathode indicated by band
• MARKING: Part number and polarity band
• WEIGHT: 1.5 grams. (Approx)
• TAPE & REEL option: Standard per EIA-296 (add
“TR” suffix to part number)
• See “CASE 1” package dimensions on last page
* TVS devices are not typically used for dc power dissipation and are instead operated < VWM (rated standoff voltage) except for transients that briefly
drive the device into avalanche breakdown (VBR to VC region) of the TVS element. Also see Figures 3 and 4 for further protection details in rated peak
pulse power for unidirectional and bidirectional configurations respectively.

NOTE: TVS are normally selected according to the reverse “Standoff Voltage” (VWM) that should be equal to or greater than the dc or continuous
peak operating voltage level.

SCHEMATIC APPLICATIONS
The TVS low capacitance device configuration is shown in Figure 2. As a further option for unidirectional applications, an additional low
capacitance rectifier diode may be used in parallel in the same polarity direction as the TVS as shown in Figure 3. In applications where random
high voltage transients occur, this will prevent reverse transients from damaging the internal low capacitance rectifier diode and also provide a
low voltage conducting direction. The added rectifier diode should be of similar low capacitance and also have a higher reverse voltage rating
than the TVS clamping voltage VC. The Microsemi recommended rectifier part number is the “ELCR80” for the application in Figure 5. If using
two (2) low capacitance TVS devices in anti-parallel for bidirectional applications, this added protective feature for both directions (including the
reverse of each rectifier diode) is also provided. The unidirectional and bidirectional configurations in Figure 3 and 4 will both result in twice the
capacitance of Figure 2.
