Frequently asked questions
What is the price of BT145-800 Thyristor (SCR) 800V 25A TO-220 Through Hole in Egypt?
BT145-800 Thyristor (SCR) 800V 25A TO-220 Through Hole currently costs 18 EGP in Egypt.
Where can I buy BT145-800 Thyristor (SCR) 800V 25A TO-220 Through Hole in Egypt?
BT145-800 Thyristor (SCR) 800V 25A TO-220 Through Hole is available from Makers Electronics. Compare the offers above to find the best price.
Can a single BT145-800 switch a full AC waveform?
No. An SCR conducts in one direction only, so it controls one half of the AC cycle. Full-wave AC control usually needs two SCRs connected in anti-parallel or a triac.
How is the BT145-800 triggered?
It is switched on by a gate trigger pulse rather than a simple logic level. Follow the gate drive and current-limiting arrangement shown in the datasheet, and isolate the control circuit from mains when working with AC.
