--nextPart2107817.ulAK4ntMGT Content-Transfer-Encoding: 7Bit Content-Type: text/plain; charset="iso-8859-1" This is a bit off-topic - but - I am reverse engineering a circuit board so that I can make a new PCB with some changes. There are two surface mounted transistors in SOT23 configuration. One that is marked "t04" and using a multimeter, it tests out as an NPN transistor and I found some documentation that states that a "t04" is a PMBS3904 which is equivalent to a 2N3904. However, the markings of the second transistor are a mystery to me (It is marked "MON") and it does not test out as an NPN or PNP transistor. I suspect that it may be a MOSFET. Does anyone have any info on this transistor??? It may be M0N (M zero N) also. I do not have catalog book here at home, but remember that come european MOSFET transitors have marking starting with "M". Especially dual gate ones (BF9xx) but they have 4 pins (SOT143). The last character may be the identifier of manufacturer. NXP (Philips) often adds "p" Wojciech Kazubski --nextPart2107817.ulAK4ntMGT Content-Transfer-Encoding: base64 Content-Type: text/html; charset="iso-8859-1" PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9XM0MvL0RURCBIVE1MIDQuMC8vRU4iICJodHRwOi8v d3d3LnczLm9yZy9UUi9SRUMtaHRtbDQwL3N0cmljdC5kdGQiPgo8aHRtbD48aGVhZD48bWV0YSBu YW1lPSJxcmljaHRleHQiIGNvbnRlbnQ9IjEiIC8+PHN0eWxlIHR5cGU9InRleHQvY3NzIj4KcCwg bGkgeyB3aGl0ZS1zcGFjZTogcHJlLXdyYXA7IH0KPC9zdHlsZT48L2hlYWQ+PGJvZHkgc3R5bGU9 IiBmb250LWZhbWlseTonTmltYnVzIFNhbnMgTCc7IGZvbnQtc2l6ZToxMXB0OyBmb250LXdlaWdo dDo0MDA7IGZvbnQtc3R5bGU6bm9ybWFsOyI+CjxwIHN0eWxlPSItcXQtcGFyYWdyYXBoLXR5cGU6 ZW1wdHk7IG1hcmdpbi10b3A6MHB4OyBtYXJnaW4tYm90dG9tOjBweDsgbWFyZ2luLWxlZnQ6MHB4 OyBtYXJnaW4tcmlnaHQ6MHB4OyAtcXQtYmxvY2staW5kZW50OjA7IHRleHQtaW5kZW50OjBweDsg Ij4mbmJzcDs8L3A+CjxwIHN0eWxlPSIgbWFyZ2luLXRvcDoxMnB4OyBtYXJnaW4tYm90dG9tOjBw eDsgbWFyZ2luLWxlZnQ6NDBweDsgbWFyZ2luLXJpZ2h0OjQwcHg7IC1xdC1ibG9jay1pbmRlbnQ6 MDsgdGV4dC1pbmRlbnQ6MHB4OyAtcXQtdXNlci1zdGF0ZTowOyBiYWNrZ3JvdW5kLWNvbG9yOiNm ZmZmZmY7Ij48c3BhbiBzdHlsZT0iIGZvbnQtZmFtaWx5OidhcmlhbCwgaGVsdmV0aWNhLCBzYW5z LXNlcmlmJzsgZm9udC1zaXplOjEycHQ7IGNvbG9yOiMwMDAwMDA7Ij5UaGlzIGlzIGEgYml0IG9m Zi10b3BpYyAtIGJ1dCAtIEkgYW0gcmV2ZXJzZSBlbmdpbmVlcmluZyBhIGNpcmN1aXQgYm9hcmQg c28gdGhhdCBJIGNhbiBtYWtlIGEgbmV3IFBDQiB3aXRoIHNvbWUgY2hhbmdlcy4gVGhlcmUgYXJl IHR3byBzdXJmYWNlIG1vdW50ZWQgdHJhbnNpc3RvcnMgaW6gPC9zcGFuPjxzcGFuIHN0eWxlPSIg Zm9udC1mYW1pbHk6J2FyaWFsLCBoZWx2ZXRpY2EsIHNhbnMtc2VyaWYnOyBmb250LXNpemU6MTJw dDsgY29sb3I6IzAwMDAwMDsiPlNPVDIzIGNvbmZpZ3VyYXRpb248L3NwYW4+PHNwYW4gc3R5bGU9 IiBmb250LWZhbWlseTonYXJpYWwsaGVsdmV0aWNhLHNhbnMtc2VyaWYnOyBmb250LXNpemU6MTJw dDsgY29sb3I6IzAwMDAwMDsiPi4gT25lIHRoYXQgaXMgbWFya2VkICZxdW90O3QwNCZxdW90OyBh bmQgdXNpbmcgYSBtdWx0aW1ldGVyLCBpdCB0ZXN0cyBvdXQgYXMgYW6gPC9zcGFuPjxhIG5hbWU9 InlpdjE1NzA2NzAwNzBsd18xMzQyMjM0NDc2XzAiPjwvYT48c3BhbiBzdHlsZT0iIGZvbnQtZmFt aWx5OidhcmlhbCxoZWx2ZXRpY2Esc2Fucy1zZXJpZic7IGZvbnQtc2l6ZToxMnB0OyBjb2xvcjoj MzY2Mzg4OyI+Tjwvc3Bhbj48c3BhbiBzdHlsZT0iIGZvbnQtZmFtaWx5OidhcmlhbCxoZWx2ZXRp Y2Esc2Fucy1zZXJpZic7IGZvbnQtc2l6ZToxMnB0OyBjb2xvcjojMzY2Mzg4OyI+UE4gdHJhbnNp c3Rvcjwvc3Bhbj48c3BhbiBzdHlsZT0iIGZvbnQtZmFtaWx5OidhcmlhbCxoZWx2ZXRpY2Esc2Fu cy1zZXJpZic7IGZvbnQtc2l6ZToxMnB0OyBjb2xvcjojMDAwMDAwOyI+oGFuZCBJIGZvdW5kIHNv bWUgZG9jdW1lbnRhdGlvbiB0aGF0IHN0YXRlcyB0aGF0IGEgJnF1b3Q7dDA0JnF1b3Q7IGlzIGGg PC9zcGFuPjxzcGFuIHN0eWxlPSIgZm9udC1mYW1pbHk6J2FyaWFsLCBoZWx2ZXRpY2EsIHNhbnMt c2VyaWYnOyBmb250LXNpemU6MTJwdDsgY29sb3I6IzAwMDAwMDsiPlBNQlMzOTA0IHdoaWNoIGlz IGVxdWl2YWxlbnQgdG8gYaAyTjM5MDQuIEhvd2V2ZXIsIHRoZSBtYXJraW5ncyBvZiB0aGUgc2Vj b25kIHRyYW5zaXN0b3IgYXJlIGEgbXlzdGVyeSB0byBtZSAoSXQgaXMgbWFya2VkICZxdW90O01P TiZxdW90OykgYW5kIGl0IGRvZXMgbm90IHRlc3Qgb3V0IGFzIGFuIE5QTiBvciBQTlAgdHJhbnNp c3Rvci4gSSBzdXNwZWN0IHRoYXQgaXQgbWF5IGJlIGEgTU9TRkVULiBEb2VzIGFueW9uZSBoYXZl IGFueSBpbmZvIG9uIHRoaXMgdHJhbnNpc3Rvcj8/Pzwvc3Bhbj48L3A+CjxwIHN0eWxlPSIgbWFy Z2luLXRvcDowcHg7IG1hcmdpbi1ib3R0b206MHB4OyBtYXJnaW4tbGVmdDowcHg7IG1hcmdpbi1y aWdodDowcHg7IC1xdC1ibG9jay1pbmRlbnQ6MDsgdGV4dC1pbmRlbnQ6MHB4OyAtcXQtdXNlci1z dGF0ZTowOyI+PGJyIC8+SXQgbWF5IGJlIE0wTiAoTSB6ZXJvIE4pIGFsc28uIEkgZG8gbm90IGhh dmUgY2F0YWxvZyBib29rIGhlcmUgYXQgaG9tZSwgYnV0IHJlbWVtYmVyIHRoYXQgY29tZSBldXJv cGVhbiBNT1NGRVQgdHJhbnNpdG9ycyBoYXZlIG1hcmtpbmcgc3RhcnRpbmcgd2l0aCAmcXVvdDtN JnF1b3Q7LiBFc3BlY2lhbGx5IGR1YWwgZ2F0ZSBvbmVzIChCRjl4eCkgYnV0IHRoZXkgaGF2ZSA0 IHBpbnMgKFNPVDE0MykuPC9wPgo8cCBzdHlsZT0iIG1hcmdpbi10b3A6MHB4OyBtYXJnaW4tYm90 dG9tOjBweDsgbWFyZ2luLWxlZnQ6MHB4OyBtYXJnaW4tcmlnaHQ6MHB4OyAtcXQtYmxvY2staW5k ZW50OjA7IHRleHQtaW5kZW50OjBweDsgLXF0LXVzZXItc3RhdGU6MDsiPlRoZSBsYXN0IGNoYXJh Y3RlciBtYXkgYmUgIHRoZSBpZGVudGlmaWVyIG9mIG1hbnVmYWN0dXJlci4gTlhQIChQaGlsaXBz KSBvZnRlbiBhZGRzICZxdW90O3AmcXVvdDs8L3A+CjxwIHN0eWxlPSItcXQtcGFyYWdyYXBoLXR5 cGU6ZW1wdHk7IG1hcmdpbi10b3A6MHB4OyBtYXJnaW4tYm90dG9tOjBweDsgbWFyZ2luLWxlZnQ6 MHB4OyBtYXJnaW4tcmlnaHQ6MHB4OyAtcXQtYmxvY2staW5kZW50OjA7IHRleHQtaW5kZW50OjBw eDsgIj4mbmJzcDs8L3A+CjxwIHN0eWxlPSIgbWFyZ2luLXRvcDowcHg7IG1hcmdpbi1ib3R0b206 MHB4OyBtYXJnaW4tbGVmdDowcHg7IG1hcmdpbi1yaWdodDowcHg7IC1xdC1ibG9jay1pbmRlbnQ6 MDsgdGV4dC1pbmRlbnQ6MHB4OyAtcXQtdXNlci1zdGF0ZTowOyI+V29qY2llY2ggS2F6dWJza2k8 L3A+PC9ib2R5PjwvaHRtbD4= --nextPart2107817.ulAK4ntMGT--
