BZX384C Overview

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

BZX384C is a Vishay order-code family — not a single orderable MPN. This page lists 15 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.

Zener Diode, 12V V(Z), 5%, 0.2W, Silicon, Unidirectional, ROHS COMPLIANT, PLASTIC PACKAGE-2 Other listed variants describe: Zener Diode, 15V V(Z), 5%, 0.2W, Silicon, Unidirectional, ROHS COMPLIANT, PLASTIC PACKAGE-2; Zener Diode, 18V V(Z), 5%, 0.2W, Silicon, Unidirectional, ROHS COMPLIANT, PLASTIC PACKAGE-2.

Suffix examples in this family: 12-E3-08, 12-HE3-08, 15-E3-08, 15-HE3-08, 18-HE3-08, 20-E3-08, 22-E3-08, 3V6-E3-08. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.

Example MPNs: BZX384C12-E3-08, BZX384C12-HE3-08, BZX384C15-E3-08, BZX384C15-HE3-08, BZX384C18-HE3-08, BZX384C20-E3-08.

Ordering Code Differences

How suffixes on BZX384C map to package, grade, and reel options.

BZX384C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.

Suffixes seen here: 12-E3-08, 12-HE3-08, 15-E3-08, 15-HE3-08, 18-HE3-08, 20-E3-08, 22-E3-08, 3V6-E3-08, 5V1-HE3-08, 5V6-E3-08 (+5 more).

Full MPN examples: BZX384C12-E3-08, BZX384C12-HE3-08, BZX384C15-E3-08, BZX384C15-HE3-08, BZX384C18-HE3-08.

Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.

How to Choose the Right BZX384C Zener 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 BZX384C, 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 "BZX384C" — include the full suffix (e.g. 12-E3-08, 12-HE3-08, 15-E3-08). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the BZX384C product family.

Is BZX384C a single part I can order, or a family prefix?

BZX384C is a base / family code from Vishay. You order a full MPN such as BZX384C12-E3-08, BZX384C12-HE3-08, BZX384C15-E3-08. The variant table lists 15 orderable lines with different suffixes.

What do the suffix letters on BZX384C part numbers mean?

Listed suffix fragments include: 12-E3-08, 12-HE3-08, 15-E3-08, 15-HE3-08, 18-HE3-08, 20-E3-08. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Vishay datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of BZX384C 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 BZX384C?

Full manufacturer MPN (not just BZX384C), 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 BZX384C 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.
