SMA6J22 Overview

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

Key Features

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

Target Applications

TVS Diodes — 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 SMA6J22 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
SMA6J22AH	Trans Voltage Suppressor Diode,	Littelfuse	Active	Compliant	In Stock	RFQ
SMA6J22CA	Trans Voltage Suppressor Diode,	Littelfuse	Active	Compliant	In Stock	RFQ

Ordering Code Differences

How suffixes on SMA6J22 map to package, grade, and reel options.

How to Choose the Right SMA6J22 TVS Diodes

📦

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 SMA6J22, 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 "SMA6J22" — include the full suffix (e.g. AH, CA). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the SMA6J22 product family.

Is SMA6J22 a single part I can order, or a family prefix?

SMA6J22 is a base / family code from Littelfuse. You order a full MPN such as SMA6J22AH, SMA6J22CA. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on SMA6J22 part numbers mean?

Listed suffix fragments include: AH, CA. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Littelfuse datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of SMA6J22 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 SMA6J22?

Full manufacturer MPN (not just SMA6J22), 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 SMA6J22 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.
