BUK9 Overview

What changes between part numbers, and what to check before you lock the BOM — MOSFETs.

Key Features

Footprint / package: SOSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
2 distinct suffix patternsExamples: MPP-55PRR, MPP-55PRR,518. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

MOSFETs — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

Ordering Variants

Compare 2 BUK9 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right BUK9 MOSFETs

📦

Match the footprint first

Packages here: SO. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For BUK9, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "BUK9" — include the full suffix (e.g. MPP-55PRR, MPP-55PRR,518). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the BUK9 product family.

Is BUK9 a single part I can order, or a family prefix?

BUK9 is a base / family code from Nexperia. You order a full MPN such as BUK9MPP-55PRR, BUK9MPP-55PRR,518. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on BUK9 part numbers mean?

Listed suffix fragments include: MPP-55PRR, MPP-55PRR,518. Typically they encode package (SO), temperature grade, and tape/reel option. Always decode on the Nexperia datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of BUK9 variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on BUK9?

Full manufacturer MPN (not just BUK9), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.

Where is the BUK9 datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
