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.
