MAXIMUM RATINGS
Peak Pulse Power dissipation at 25 ºC: 1500 watts at 10/1000 μs (see Figure 1) with impulse repetition
rate of 0.01% or less* at lead temperature TL of 25°C
Operating & Storage Temperatures: -65 ºC to +150 ºC
Thermal Resistance: 22 ºC/W junction to lead at 3/8 inch (10 mm) from body, or 82 ºC/W junction to
ambient when mounted on FR4 PC board with 4 mm2 copper pads (1oz), track width 1 mm, length 25mm
Steady-State Power dissipation*: 5 watts at TL = 40 ºC, or 1.52 watts at TA = 25 ºC when mounted on
FR4 PC board described for thermal resistance
Solder Temperatures: 260 ºC for 10 s (maximum)
* TVS devices are not typically used for dc power dissipation and are instead operated at ≤ VWM 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 power for unidirectional and bidirectional configurations respectively.

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.
