> However, you can't just put two diodes in parallel and add their > current ratings. This is because they won't share the current equally I see that now. The circuit which made me pose the original question uses switching FETs in parallel, with individual gate resistors. AIUI FETS have a negative temperature coefficient, ie local hotspots on the die increase in resistance, thereby causing a temperature decrease, so there is no thermal runaway. The suggested 2 Schottky =3D 1 UF sub does not mention load-sharing resistors, as you'd find on paralleled power bipolar transistors for example, which would prevent current hogging Thanks for everyone's input Joe * * ********** Quality PIC programmers http://www.embedinc.com/products/index.htm --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
