SMMBZ33VALT 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: 1G, 3G. 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 SMMBZ33VALT part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right SMMBZ33VALT 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 SMMBZ33VALT, 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 "SMMBZ33VALT" — include the full suffix (e.g. 1G, 3G). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the SMMBZ33VALT product family.

Is SMMBZ33VALT a single part I can order, or a family prefix?

SMMBZ33VALT is a base / family code from onsemi. You order a full MPN such as SMMBZ33VALT1G, SMMBZ33VALT3G. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on SMMBZ33VALT part numbers mean?

Listed suffix fragments include: 1G, 3G. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the onsemi datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of SMMBZ33VALT 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 SMMBZ33VALT?

Full manufacturer MPN (not just SMMBZ33VALT), 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.
