Voltage Clamp
Voltage Clamp
Firstly I would like to say a big thanks for the recent repair to my Roboclaw. I can highly recommend Ion Motion going by the customer service I have just received. I have started to experiment using the BUK965R8 as recommended for the voltage clamp. The one I received is a surface mount version as that's all I could find in Australia. While I have mounted it to a heat sink and it is running I was wondering what your thoughts are on using the following parts instead of the BUK965R8. My reason for this question is that it can be mounted to a heat sink. A second question is the BUK965R8 available as a bolt hole mountable version or is there one you recommend that will. ( a link to where I could get one would be appreciated.

Re: Voltage Clamp
Unfortunately I cant garuntee either of those solid state relays will work. The control voltage range is 4 to 32v. The Roboclaw will only output approx 3.3v.
You can use a different mosfet, however it needs to turn on at or below 3.3v which usually means a logic level mosfet. Also it should have a voltage rating 25%(or higher) above the expected running voltage. Maximum current could be as low as a couple amps but I'd err on the side of a higher current cable mosfet. It will heatup less if noting else.
