PMBT5551 Overview

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

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
2 distinct suffix patternsExamples: ,215, ,235. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

BJTs — 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 PMBT5551 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Part Number	Description	Manufacturer	Lifecycle	RoHS	Availability	Action
PMBT5551,215	Trans GP BJT NPN 160V 0.3A 250mW Automotive 3-Pin SOT-23 T/R	Nexperia	Active	Compliant	In Stock	RFQ
PMBT5551,235	PMBT5551 - NPN high-voltage transistor TO-236 3-Pin	Nexperia	Active	Compliant	In Stock	RFQ

How to Choose the Right PMBT5551 BJTs

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For PMBT5551, 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 "PMBT5551" — include the full suffix (e.g. ,215, ,235). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the PMBT5551 product family.

Is PMBT5551 a single part I can order, or a family prefix?

PMBT5551 is a base / family code from Nexperia. You order a full MPN such as PMBT5551,215, PMBT5551,235. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on PMBT5551 part numbers mean?

Listed suffix fragments include: ,215, ,235. Typically they encode package (see Package column), 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 PMBT5551 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 PMBT5551?

Full manufacturer MPN (not just PMBT5551), 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 PMBT5551 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.
