Mosfets are the way to go.<div>The on resistance is down to 0.018 ohms on some that I use for vibrator subs. BJTs pale in comparison.</div><div>A pair of mosfets can&nbsp; be driven by a cd4047 with no gate drivers! Very low parts count with this config.</div><div>For more ambitious high voltage and current</div><div>Projects , there are specialized gate driver Ics</div><div>Which simplify the build. They have very good rise/ fall times too.</div><div><br></div><div><br><br><div id="ymail_android_signature"><a id="ymail_android_signature_link" href="https://mail.onelink.me/107872968?pid=NativePlacement&amp;c=Global_Acquisition_YMktg_315_EmailSignatureGrowth_YahooMail:Search,Organize,Conquer&amp;af_sub1=Acquisition&amp;af_sub2=Global_YMktg&amp;af_sub3=&amp;af_sub4=100000945&amp;af_sub5=OrganizeConquer__Static_">Yahoo Mail: Search, Organize, Conquer</a></div> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;"> <div>On Tue, Jun 25, 2024 at 1:59 PM, Ray Fantini via MRCA</div><div>&lt;mrca@mailman.qth.net&gt; wrote:</div> </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> ______________________________________________________________<br clear="none">MRCA mailing list<br clear="none">Home: <a shape="rect" href="http://mailman.qth.net/mailman/listinfo/mrca" target="_blank">http://mailman.qth.net/mailman/listinfo/mrca</a><br clear="none">Help: <a shape="rect" href="http://mailman.qth.net/mmfaq.htm" target="_blank">http://mailman.qth.net/mmfaq.htm</a><br clear="none">Post: mailto:MRCA@mailman.qth.net<br clear="none"><br clear="none">This list hosted by: <a shape="rect" href="http://www.qsl.net" target="_blank">http://www.qsl.net</a><br clear="none">Please help support this email list: <a shape="rect" href="http://www.qsl.net/donate.html" target="_blank">http://www.qsl.net/donate.html</a> </div> </blockquote></div>
