Help identifying SMD transistor
Hi, can anyone identify a transistor for me, this is from a LCD monitor
inverter board. The markings on the transistor are DJ R |

And a picture of the transistor or better yet, the package style, and the location identifier would be a big help. Now, because I'm smarter than average (Arfa Daily taught me well), the information you seek might be he http://www.s-manuals.com/smd/dj PlainBill |

The Monitor is a Digimate L-1715 17 inch. Some research I have found transistors labelled RE that are high frequency, I wonder if these are the ones, as they appear to drive the transformer that feeds the backlight. Only problem I'm having is sourcing them cheap. |

Some research I have found transistors labelled RE that are high frequency, I wonder if these are the ones, as they appear to drive the transformer that feeds the backlight. Only problem I'm having is sourcing them cheap. I'm not noted for patience with the obtuse. Read the datasheet. The parts are made by Rohm. DJ identifies the part number - 2SD2098. The R specifies the gain - R being the high gain version. E indicates a production date, lot, factory, etc. As far as a supplier, if you live in the USA you can buy them from Digikey at $.80 each. Shipping will run about $2.50 IF you specify first class mail. Without even looking up the monitor, I can tell you the inverter uses a pair of Royer oscillators; two transistors are used on each oscillator. Common failure points are bad solder joints on the transformers, a failure of the timing cap, or a shorted diode. PlainBill |
