STMicroelectronics STB34NM
STB34NM variants from STMicroelectronics
STB34NM Overview
What changes between part numbers, and what to check before you lock the BOM — MOSFETs.
STB34NM is a STMicroelectronics order-code family — not a single orderable MPN. This page lists 2 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.
600V N-Ch MOSFET, 29A, 0.092 Ohm, D2PAK, Surface Mount Other listed variants describe: 600V 29A N-CH MOSFET D2PAK, 110mR RdsOn.
Suffix examples in this family: 60N, 60ND. 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: STB34NM60N, STB34NM60ND.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 60N, 60ND. 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 2 STB34NM 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 |
|---|---|---|---|---|---|---|
| STB34NM60N | 600V N-Ch MOSFET, 29A, 0.092 Ohm, D2PAK, Surface Mount | STMicroelectronics | Active | Compliant | In Stock | |
| STB34NM60ND | 600V 29A N-CH MOSFET D2PAK, 110mR RdsOn | STMicroelectronics | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on STB34NM map to package, grade, and reel options.
STB34NM 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: 60N, 60ND.
Full MPN examples: STB34NM60N, STB34NM60ND.
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 STB34NM 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 STB34NM, 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 "STB34NM" — include the full suffix (e.g. 60N, 60ND). RFQ with reel/tube preference and required date code.
