На МХ6.сом советуют заменить на IRGB14C40L
А вот ссыла про замену.http://www.mx6.com/forums/2g-mx6-general/75053-distributor-transisitor-part-number.html
Hi Guys. Took apart my current disty last night. Couldn"t get a part number off that. Was potted in the first place and secondly it worked hard and the potting was burnt, so I couldn"t get the P/N. All I know is that the replacement I have in now, is a TO-220 package. The M67580 package is a TO-247 package. Doesn"t really matter, as long as the package can handle the spec.
I"ve looked at the IR possible replacement, the IRGB14C40L. This one is specifically designed for ignition systems.
A transistor is not a transistor. The specific requirement for the disty switching application is the following:
- High operating temperature (>100 C)
- Low Vce(on) in the order of 1.5V
- High current & voltage capability ~14A (@100 C) and 400 to 600V
- Maximum Frequency ~ 400 Hz (8000 rpm / 2 (for 4 stroke) * 6 (cylinders) / 60 (minutes to seconds for Hz)
The max freq is low, but the rise and fall times must be short for proper switching. If you"re rise and fall times is too long, the voltage generated by the coil, would be lower, thus bad spark, bad ignition, bad performance etc. Thus a 1 kHz IBGT would suffice with as rise/fall time of micro seconds.
A MOSFET will go crazy with such a noisy signal and environment on it"s gate.
So the only thing I still need to check is the N or P channel. First I have to get all the potting out to get to the pins. :-) Still looking for the datasheet for the Mitsibishi one, to save me some work
