2N6347A Silicon Diac/Thyristor from China
The 2N6347A is a bidirectional trigger diac semiconductor used to initiate thyristor conduction in dimmer circuits and timing applications. It fits HTS 8541.30.0080 as 'other' thyristors/diacs, withstanding 400V without photosensitive properties. Its DO-15 package is standard for trigger devices in power control systems.

Import Tips
• Distinguish diacs from zener diodes in docs by specifying bidirectional breakdown voltage symmetry
• Small form factor imports often undervalued; use published distributor pricing for invoices
• Require halogen-free certification for EU RoHS compliance during US transshipment
