I NEED HELP IN TRYING TO DETERMIN HOW MANY MOSFETS ARE IGBT'S I WOULD NEED
TO ALLOW 500VDC MAX. AT 150 AMPS DC CONSTANT TO FLOW IAM TRYING TO USE A 3" X 3" ARE 3" X 6" BOARD DEVICES ON BOTH FRONT AND BACK, WITH SINGLE ROW SIP CONNECTORS
SO I CAN STACK THE BOARDS IF NEED BE , IN CASE I NEED TO PUT 3 ARE 4 BOARDS TOGETHER TO GET THE RSDon LOW ENOUGHT TO ALLOW 150 AMPS TO FLOW WITH OUT OVER HEATING, AND NO NEED OF HEATSINK PER BOARD, I WOULD LIKE TO USE D2K PK'S
CALL ME DIRECTLY AT 561-853-4160 ANY TIME DAY ARE NIGHT INCLUDING WEEKENDS
THANKS SO MUCH THIS IS OF A URGENT MATTER
This depends almost entirely on what MOSFETs you intend on using. I can tell you that currently, TI does not offer any high voltage (200V +) FETs. Most FETs have an operating temperature of -50 to 150 degrees. And most D2PAK's have a package limit current of 100 A. Some may have extra pins and may be able to go to 195A. However, this is just a package limit and preventing overheating depends on what type of heat sink you use and the ambient temperature that your device will operate in. Best case scenario, if you use this special package, with a heat sink, you might be able to get away with just one. Otherwise, it will take at least two, if not three FETs in parallel. Thanks,
