Hi,

This is from a Blitz 1jz ecu. The three circled thyristors need replacement, they are part of the injection. The problem is that because they are fried I cannot measure what they should be to get replacements.
The numbers on them (NEC D2162 K 08) don't give me anything on the web, I've only found out that they are toyota specific components, but couldn't find any specs.

Or perhaps someone has an 1jz ecu which has gone dead beyond repair and could sell me these thyristors from it?
Thanks.

Edit: changed the mistake saying the circled parts are for ignition, as they are part of the injection.

Based on this it may drive the three stepper windings or the fuel system since its not sequential.

2SD2162

NPN SILICON EPITAXIAL TRANSISTOR (DARLINGTON CONNECTION) FOR LOW-FREQUENCY POWER AMPLIFIERS AND LOW-SPEED SWITCHING

The 2SD2162 is a Darlington power transistor that can directly drive from the IC output. This transistor is ideal for motor drivers and solenoid drivers in such as OA and FA equipment. In addition, a small resin-molded insulation type package contributes to high-density mounting and reduction of mounting cost.

(Isolated TO-220)

FEATURES
• High hFE due to Darlington connection hFE ≥ 2,000 (VCE = 2.0 V, IC = 3.0 A) • Full mold package that does not require an insulating board or insulation bushing

Now that you mention it, yes, I think you're right.

I purchased the TIP122's today as these were the only ones the local radio shop had. The NEC's were quite hard to get hold of over here (The Netherlands) the guy said.

So I tried the TIP122's today. The car started and ran for a few seconds but died because it went pig rich. Tried it a couple of times; same result. (I do have a working Blitz ecu which is normally used in the car, just to be clear on this.)
It is a step forward as before the car wouldn't even start at all with the fubar ecu. So the problem is definitely these transistors, but the TIP122's are not the right replacement.

Now I'm looking for a place to buy the 2SD2162's to give those a try. I couldn't find a local shop who has them but also on the web I can't find any webshop which sells them.
Anybody know of a website where I could order these?

The more I look at it the compenents the more I believe they drive the injectors!
You need the right ones to drive the circuite with the specs provided on the data sheet just match them up.

What did you do to fry the chips goto 550s with out the resistor pack? extend the harness in a fashion to damage the ECU ?

So, I ordered three 2SD2162's through www.utsource.net and have received them. I've installed them and the ecu works fine again :)

@ Evil, yes, they drive the injectors and I can't remember what exactly I did wrong. It had to do with the wiring. It was a couple of years ago just before I went on holiday with the supra. Then I just bought another one because the car needed to run and put this one on the 'to-be-fixed-when-I-have-the-time' shelf. Lately I came across it again and decided to give it a try to fix it and voila! it works again. :)
Now I'm gonna put it in my supra for a little while to see if it is 100% OK and then, if all is well, put it up for sale.

Cool to see your car good & running I should get into ECU repair.

I used to repair avionics and hospital imaging and telemetry equipment to component level.

I now work Repairing, calibrating, software just about everything for locomotives for Union Pacific.
