STMicroelectronics STB80NF
STB80NF variants from STMicroelectronics
STB80NF Overview
What changes between part numbers, and what to check before you lock the BOM — MOSFETs.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 3 distinct suffix patternsExamples: 03L-04T4, 10T4, 55-06T4. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- MOSFETs — 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 3 STB80NF 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 |
|---|---|---|---|---|---|---|
| STB80NF03L-04T4 | 30V 80A N-Ch MOSFET D2PAK 4mR RdsOn | STMicroelectronics | Active | Compliant | In Stock | |
| STB80NF10T4 | 100V 80A N-CH MOSFET D2PAK 15mR Rds(on) | STMicroelectronics | Active | Compliant | In Stock | |
| STB80NF55-06T4 | 55V 80A N-CH MOSFET D2PAK 6.5mR Power Transistor | STMicroelectronics | Active | Compliant | In Stock |

How to Choose the Right STB80NF MOSFETs
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 STB80NF, 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 "STB80NF" — include the full suffix (e.g. 03L-04T4, 10T4, 55-06T4). RFQ with reel/tube preference and required date code.
