Product Details
Key Features
Documentation

This family of 2N3439 through 2N3440, high-frequency, epitaxial planar NPN transistors have a low saturation voltage, and are military qualified up to the JANS level for high-reliability applications. These transistors are available in a TO-205AD (TO-39) ,no suffix, a TO-205AA (TO-5), L suffix and a low profile surfacemount U4 and UA packaging. Microchip also offers numerous other transistor products to meet higher and lower power ratings with various switching speed requirements in both through-hole and surface-mount packages.

YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is 2N3439U4-TR-Transistor, and what package does it use?

2N3439U4-TR-Transistor is an authentic electronic component manufactured by Microchip, categorized under Transistors. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official 2N3439U4-TR-Transistor datasheet above.

Why is pricing for 2N3439U4-TR-Transistor available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for 2N3439U4-TR-Transistor fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can 2N3439U4-TR-Transistor be shipped once quoted?

Lead times for 2N3439U4-TR-Transistor depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
