MIC5209 Overview

What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).

Key Features

Footprint / package: TO-261-4, TO-261AA, TO-263-6, D²Pak (5 Leads + Tab), TO-263BALand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
13 distinct suffix patternsExamples: 5.0YS-TR, 5.0YU-TR, 1.8YM-TR, 2.5YM-TR, 3.0YM (+8 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Integrated Circuits (ICs) — 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

How to Choose the Right MIC5209 Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: TO-261-4, TO-261AA, TO-263-6, D²Pak (5 Leads + Tab), TO-263BA. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For MIC5209, 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 "MIC5209" — include the full suffix (e.g. 5.0YS-TR, 5.0YU-TR, 1.8YM-TR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the MIC5209 product family.

Is MIC5209 a single part I can order, or a family prefix?

MIC5209 is a base / family code from Microchip Technology. You order a full MPN such as MIC5209-5.0YS-TR, MIC5209-5.0YU-TR, MIC5209-1.8YM-TR. The variant table lists 13 orderable lines with different suffixes.

What do the suffix letters on MIC5209 part numbers mean?

Listed suffix fragments include: 5.0YS-TR, 5.0YU-TR, 1.8YM-TR, 2.5YM-TR, 3.0YM, 3.3YM. Typically they encode package (TO-261-4, TO-261AA, TO-263-6, D²Pak (5 Leads + Tab), TO-263BA), temperature grade, and tape/reel option. Always decode on the Microchip Technology datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between MIC5209 variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between TO-261-4, TO-261AA, TO-263-6, D²Pak (5 Leads + Tab), TO-263BA packages in the same MIC5209 family?

Only after footprint and thermal review. Packages listed here (TO-261-4, TO-261AA, TO-263-6, D²Pak (5 Leads + Tab), TO-263BA) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of MIC5209 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 MIC5209?

Full manufacturer MPN (not just MIC5209), 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 MIC5209 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.
