1500 WATT LOW CAPACITANCE
TRANSIENT VOLTAGE SUPPRESSOR

DESCRIPTION
APPEARANCE
This hermetically sealed 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
DO-13
(DO-202AA)
opposite directions (anti-parallel) for complete ac protection as shown in Figure 4.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

MECHANICAL AND PACKAGING
• 1500 Watts at 10/1000 μs with repetition rate of 0.01% or
•
CASE: DO-13 (DO-202AA), welded, hermetically
sealed metal and glass
less* at lead temperature (TL) 25oC (see Figs. 1, 2, & 4)

plated and solderable per MIL-STD-750 method 2026
• THERMAL RESISTANCE: 50oC/W (Typical) junction to
lead at 0.375 inches (10 mm) from body or 110 oC/W
junction to ambient when mounted on FR4 PC board with
4 mm2 copper pads (1 oz) and track width 1 mm, length
25 mm
POLARITY: Cathode connected to case as shown by
diode symbol (cathode positive for normal operation)
•
•
•
MARKING: Part number and polarity diode symbol
WEIGHT: 1.4 grams. (Approx)
• DC Power Dissipation*: 1 Watt at TL < +125oC 3/8” (10
mm) from body (see derating in Fig 3 and note below)
• Solder Temperatures: 260 o C for 10 s (maximum)
TAPE & REEL option: Standard per EIA-296 (add
“TR” suffix to part number)
•
See package dimension 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 “LCR80” 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.
