Skytronics (Nikkai) inverter transistors
Hi all,
Can anyone identify the following semiconductors? They are used in the Skytronics, Nikkai range of mains inverters as driver devices for the Mosfet o/p switching. I think these are TO 220 cases. Q8/9 are Motorola devices and the numbering is :- ---------- | B20 | | J E| | 3003 | ---------- | | | Q11/12 again are odd with no mftr marking :- ---------- | H LB | | 123T | | 7GT | ---------- | | | Info for these inverters can be found here :- http://www.bfisk.demon.co.uk/SkyTronic/skytronic.html If anybody has anymore info to share drop me a line. Cheers Bob |

Actually, they are TO-126 cases!
Any help at all would be most gratefully received!! Richard On 23 Sep 2003 02:44:24 -0700, (Bob) wrote: Hi all, Can anyone identify the following semiconductors?

Sorry if top post is frowned on ....
The B20 's are most likely 2SB20 trannies, see http://homepage3.nifty.com/ebina2540...B0012-0100.htm The others are LB123T see http://www.alcava.it/Italia/partricam.htm 73 G6JAP (Technician not Artist !)
