MAXIMUM RATINGS
.
Peak Pulse Power dissipation at 25 ºC: 500 watts at 10/1000 μs with impulse repetition rate
(duty factor) of 0.01 % or less*
.
.
.
.
tclamping (0 volts to VBR min.): < 5 ns theoretical for unidirectional
Operating and Storage temperature: -65 °C to +150 °C
Steady-State Power dissipation*: 2.5 watts at TL = +75 ºC
Solder temperatures: 260 ºC for 10 s (maximum)
* 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 5 and 6 for further protection details in rated peak pulse power for
unidirectional and bidirectional configurations respectively.
