|
|
Hi all
Can anyone provide more info on a semiconductor with casing T220, 3 pin (looks like a power transistor/SCR etc) and marked as TFK517.
This belongs on a power supply and motor control board for a Bernina 1080 sewing machine.
I have the service manuals but of no use as they contain no electrical schematics and all they say is "Replace Board"
Much Obliged. |

All I can say is that the TFK517 is a Telefunken device, info on it appears to be a little shy.... usually a clue can be had by studying the circuit.
Sorry I can't be of more help,.

Thanks Pentode. Been searching the net for hours on this one but no go ... strange component this one I'm almost sure it's an SCR.
Cheers. |

OR a TRIAC. |

Is an electronic component equivalent to two silicon-controlled rectifiers SCRs/thyristors joined in inverse parallel.
It results in a bidirectional electronic switch which can conduct current in either direction when it is triggered (turned on) and thus doesn't have any polarity.
Gate trigger electrode is common to this configuration.
A common Triac is a: BTA 06-600A (ST) very frequently used in light dimmers or, with appropriately developed circuitry, as a motor speed variator / control. |

|
|
the second label on that part is more important - 130 05
It's a NPN Power Transistor - e.g. TE13005
I found it here: bg-electronics.de/shop/product_info.php/products_id/1738 ..and have used it for a Bernina 1090 sewing machine - it worked
best wishes |
