Nexperia PESD12VS
PESD12VS variants from Nexperia
PESD12VS 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.
- 6 distinct suffix patternsExamples: 1UA,115, 1UB,115, 1UJ,115, 1UL,315, 1ULD,315 (+1 more). 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

How to Choose the Right PESD12VS 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 PESD12VS, 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 "PESD12VS" — include the full suffix (e.g. 1UA,115, 1UB,115, 1UJ,115). RFQ with reel/tube preference and required date code.
