Vishay semiconductors
Vishay diode, protection and MOSFET requirements, reviewed by exact part number. We support independent distribution through our own inventory and established China supply relationships.
Independent supply for your approved devices
Discrete-device procurement depends on the exact electrical and package identity. Nominal voltage, case outline or a short marking is not enough to establish an approved substitute.
We review the requested model and proposed lot independently. This page does not claim Vishay authorization, manufacturer warranty coverage or live stock for every device in the portfolio.
About our independent distribution modelCheck the exact ordering model
Keep device identity and offered-lot details separate.
The most useful RFQ starts with an approved full manufacturer part number, then adds your commercial and acceptance requirements. Use the checks below to make those requirements clear.
| Check | Why it matters | What to send |
|---|---|---|
| Device and full suffix | Device function and ordering options must stay attached to the exact MPN. | Send the complete manufacturer code, including packing suffixes. |
| Ratings and application | Similar headline ratings can hide different operating characteristics. | Use the exact datasheet and your engineering-approved limits. |
| Package and pin assignment | Mechanical resemblance does not establish an electrical match. | Identify the approved footprint and pin configuration. |
| Reel and lot details | Standard carrier information does not prove actual lot condition. | State quantity, reel condition, date-code and source-document requirements. |
Source documents and acceptance
Define what needs to be verified before the order.
For low-cost protection or switching devices, lot identity and documentation still matter. We coordinate independent inspection against the agreed methods and sample plan.
Visual evidence cannot certify all protection, leakage or switching characteristics. Include any electrical acceptance criteria in the RFQ, with the required conditions and limits.

Browse related procurement guidance or send an unlisted requirement.
Use these related pages to narrow the device identity and the evidence needed for your order. If your exact part is not listed, send the complete MPN and quantity. We review available stock and additional supply options against your requirements.
Pricing, lot details and delivery are confirmed in the quotation. For multiple parts, send your BOM with one ordering code per line.
Before you enquire
Can you identify a replacement from a package photograph?
A photograph can help, but it does not establish an approved electrical replacement. Provide the original MPN and obtain engineering approval for alternatives.
Is a generic report sufficient for an order?
It illustrates the reporting approach only. Order-specific evidence must identify the actual device, lot, samples and methods covered.
Bring us your exact requirement.
