Re: What is it?

Mystery solved! I found a Panasonic VCR that uses almost the identical SMPS. The schematic identifies PR1 as a UN10015, a three-terminal protector, one of which is unused. Many thanks to all who took the time to help. 73, Edd.

Re: What is it?

Thanks, Edd. I'm repairing this thing right now. Lightning got C5,D4,D16,IC1,Q1,Q2,R23 & the fuse. Just had never seen a PR in that case w/3 leads. Thanks, again. Do you happen to know the value of R23? Is it 68? Stuart.

Re: What is it?

Thanks for the effort, Edd. It's a Quasar VH6300, no schem. Looks to be way past the transf. and the opto., but still on p/s board. Could be a problem as two pins show a short. Does have notch & beveled edge like transist.

Re: What is it?

No logo. Below the "N10015" and to the right is something that looks like this: .8_o. In reality, the dot is at the top, the loops of the eight are squared off and the o is on top of the _. Couldn't draw it right here.

What is it?

While repairing a VCR SMPS, I noticed a component I have never seen before. It's labeled PR1 on the board, is housed in a 3-pin SIP (MT2) package like a 2SC2021 transistor and has "N10015" stamped on it. Research showed nothing. Any ideas? Thanks.
