Identify transistor?
Repairing a small circuit. Q1 is a small transister marked 603 9ze.
I can't find any data on this marking. Help? Thanks JR |

put finger to keyboard and composed: Repairing a small circuit. Q1 is a small transister marked 603 9ze. It might help if we knew which marking, if any, was the date code. Are there similar transistors, and if so, what are their markings? What are the date codes in the ICs, if any? Are the other components of Japanese or US origin, or somewhere else? That might help us narrow down the manufacturer. Is it a MOSFET or a BJT? P-channel, N-channel, NPN, PNP? What is its function? Is it part of a power supply? Switchmode? Linear? - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Due to it's small size, they abbreviate the number to 603. Fairly common in consumer electronics. Mark Z. |
