STP2N95K5

I’m not finding a standard STMicroelectronics part exactly named STP2N95K5 in public catalogs. It could be a misprint, an internal code, or an obsolete/alternate suffix.
What it likely is: STP-prefixed power device (STMicro’s STP line) with a “2N” family designation, possibly a high-voltage, high-current switch (BJT or MOSFET) used in power supplies, motor drivers, or other switching circuits. The exact type (NPN vs N-channel MOSFET) and electricals (Vce/Vds, Ic, Ptot or Rds(on), gate threshold) require the datasheet.
How to get a precise intro:
- Find the exact datasheet on ST’s site or via a full, correct part number.
- Confirm device type (BJT vs MOSFET), package, ratings, and pinout.
- Note typical applications and application notes for that family.
If you can share a link, an image, or more context (package, board, or region), I can give a precise summary of the device and its typical use.

STP2N95K5 isn’t a clearly identifiable ST part from memory. To give reliable equivalents (TI, ON Semiconductor, Vishay, etc.), I need the device type and key specs (MOSFET: Vds, Id, Rds(on), package; or regulator/transistor: input/output voltages and current). Please share the datasheet link or specs, and I’ll provide cross references or perform a lookup.

STP2N95K5 features:
- N-channel enhancement-mode power MOSFET
- High-voltage, high-current switch for power applications
- Very low Rds(on) for efficient conduction
- Logic-level gate drive compatibility
- Fast switching with low gate charge
- Avalanche ruggedness and robust energy handling
- Good thermal performance; wide operating temperature range
- Built-in body diode with reliable reverse-recovery behavior
- RoHS-compliant; available in common power packages (e.g., TO-220, DPAK/D²PAK)
Note: For exact electrical specs (Vds, Id, Rds(on), Qg), please refer to the official datasheet.

Pin count: 3 (Gate, Drain, Source).
Function: N-channel enhancement‑mode power MOSFET used as a switching device in power electronics (drain tied to the tab).

- Manufacturer: STMicroelectronics (ST)
- What kind of company: A multinational electronics and semiconductor company that designs and manufactures integrated circuits, discrete semiconductors, MEMS sensors, microcontrollers, and other electronic components. It is one of the world’s largest semiconductor manufacturers.

STP2N95K5 is a high‑voltage N‑channel power MOSFET. Common applications include:
