Look for “Typical V AC dimmer circuit. In my previous posts on this thread I have a photo of the circuit board and there are inputs on the pcb that bts12 perpendicular to each other.

May 6, 8. Here is a link that has some component values.

Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment btz12 delivery. I’ve attached a pic of the lamp and the pcb. However, STMicroelectronics assumes no responsibility for the consequences of use of such information bta2 for any infringement of patents or other rights of third parties which may result from its use.

The other thing I guess I could do is just replace the pot. May 4, 4. We will send the goods within the lead time after we receive your payment.

Maximum power dissipation versus RMS on-state current full cycle. You can ensure product safety by selecting from certified suppliers, including 1 with ISO certification. Surge peak on-state current versus number of cycles. Buyer is responsible for any insurance, problems or damages which occures during the shipment.


May 4, 3. Any items must be returned in their original condition to qualify for a refund or replacement. I’d like to design a new board in place of that one but don’t really have experience designing a circuit. Also, is that long metal piece coming off the triac for heat dispersion? I think I will redesign the circuit to incorporate the inductor choke because I remember noticing a significant buzz when the lamp was working.

Awesome thanks for all the info. Average gate power dissipation.


This publication supersedes and replaces all information previously supplied. Relevancy Transaction Level Response Rate. Is this diagram from the circuit you pulled out of the lamp?

The circuit used to dimm the lamp is probably a phase concrol circuit of some kind. I actually tried drawing up the schematic from the current board for the lamp. Hello, The drawn coil is the loadin your case the lamp.

Relative variation of critical rate of decrease of main current versus junction temperature. May 4, 1. In your drawing you have drawn 2 capacitors, I think one of them is the diac. I assume there is a bt1a2 ac signal coming which I input to the pot, but then it looks like there are 2 caps and a resistor in parallel with the pot? Junction to case AC.
