ovoj stranici pise, to je Logic-Level MOSFET za auto elektroniku i zamena mu je BUK9620-55.
Evo prevod sa poljskog spomenute stranice:
... transistors puzzling TrenchMOS ™,controlled logical level, R4363 R4389 R8947 BUK7628 are not available in the commercial market, found in newer cars eg Peugeot 406 HDI ECU "Common Rail" MB Sprinter, 2001 CR BOSCH EDC 15C2 Peugeot etc ...
R4363, R4389, R8947, BUK7628 will replace the transistor from NXP / Philips / BUK9620 BUK9620-55
