Operation at elevated load currents up to 10 amps is dependent on the use of suitable heatsink to limit junction temperature. 2. Heating of output chips during and after a surge may cause loss of output blocking capability until junction temperature falls below maximum rating. 3. Internal snubber network is provided across output chips.
