Diodes, Transistors & Discrete Components

Discrete components such as diodes, transistors, and MOSFETs are grouped by specification and packaging.

Three things to check first

Match the complete part number, lot, quantity and packaging photos to each list entry.

Do Not Guess Part Numbers from Markings Alone

Markings on small packages may correspond to different devices. Provide the brand, full part number, original labels, and packaging photos; part numbers that cannot be confirmed should be marked separately.

List Specification Differences on Separate Lines

Voltage, current, package, polarity, and part number suffix may affect matching. Mixed materials, loose stock, and full-reel inventory should be recorded separately.

Describe Quantities and Defects in Advance

Record full-reel quantities, partial-reel quantities, and the basis for estimates. Document bent leads, damage, oxidation, and similar conditions with photos; do not use a generic product name to conceal differences in condition.

Prepare inventory information that can be checked

Discrete components such as diodes, transistors, and MOSFETs are grouped by specification and packaging. A preliminary review of submitted information and a final physical inspection are separate steps.

  • Manufacturer, full part number, quantity and count date
  • Lot / date code, packaging and opened status
  • Location, list version and representative label photos
  • Known issues and any confidentiality requirements

From information to handover

Prepare the list

Separate part numbers, quantities, lots and condition.

Clarify the scope

Match labels and photos to the review and inspection needs.

Agree the terms

Confirm price, logistics, discrepancies and settlement.

Document handover

Keep the agreed list and receiving records.

Before sharing sensitive information, discuss confidentiality scope, access, image use and retention. Initial valuation does not require unrelated project design files.
