Diode OF4455??

Not open for further replies.

Hello everybody!

I have a burnt diode on a car Bosch control unit. This diode has this reference on it:

OF4455 PEM0527 E7

I think it's a Philips TO-220 diode that is no longer manufractured. Does someone know if there's any other equivalent diode I could use?
Thank you in advance for your time and help.

Best regards

Wonder why there is no datasheet exists for OF4455?

One of the cases where it was manufactured by Philips for a "customer"; in this case Bosch which kept it confidential.
And promptly discontinued ~2004 as no doubt there was a change in car Models.
However, the EOL (end of life) notice will shed some light;)

Look at page 11 of the following document. No specific description for items 206,207 but it is definitely a Schottky

I'd say a 5A or higher schottky in TO-220 should do the job.

Thank you vtech for the reply!

Any idea about the rest of specifications? Voltage, amperage peak?

Thank you again!
