![]() Hi,
Am after the part number for this unit used in an old Ford Capri for boosting spark ignition. Unit is MSD6AL and Q204 is the damaged part. If I can figure out at least if it is a Mosfet type or Bipolar Transistor like MJE3055T as used in older Models. Any help appreciated! |

![]() I think it is a N Channel Mosfet as marked with Mitsubishi Logo and starts with
FS7........ FS70KM-2 VDss 100v, Id 70A looks a good contender. http://pdf.datasheetcatalog.com/data...on/mXrqvuq.pdf According to Transformer thick windings that is switched solely from this Q240, 70A seems reasonable. This winding is 1 side 12v and the other switchable by Q240 so 100v is also in range. What do you think? |

![]() From another MSD 6AL repair blurb:
TC4627 has voltage-doubler 2.2uF tantalum caps that fail. BUP213 IGBT 1,200V 32A or IRG4PH40K FS70KM or IRF1010E if you add insulator. FS70KM-02 is 100V 70A 20mR FS70KM-06 is 60V 70A 7.5mR IRF1010E is 60V 84A 12mR Plastic TO-220 fullpack aren't great at getting rid of heat. The 1N5244A zener apparently can go too if the mosfet shorts. Higher voltage mosfets have higher RDS on, which will make them run hotter. |
