Authenticity & Authorized
Buy Genuine VBsemi Parts
Counterfeit devices marked with VBsemi part numbers circulate through unauthorized resellers and online marketplaces. Genuine VBsemi products are not affected. This page shows where to buy authentic parts, how to verify one in three steps, and how to report a suspected counterfeit.
1. Authorized Distribution
VBsemi sells only through authorized distributors. Current authorized channels include Sekorm and designated regional agents.
Sekorm — authorized distributor
Designated regional agents
Before you order: confirm the seller appears on our authorized list. If you are unsure, ask us first — it takes a minute and prevents a costly design-in failure.
2. Verify a Part in 3 Steps
Check the part number — compare the marking against our published datasheet.
Inspect the lot code and laser marking — look at the device body and the reel label. Marking style, font and placement should match genuine product.
Get official confirmation — send the part number and lot code to SZ@VBsemi.com, or use the serial number verification tool on this website.
3. Genuine vs Counterfeit
Genuine VBsemi devices match our published datasheets in package, marking and electrical specifications. Counterfeits copy the appearance only.
