PMEG2005EGW-QX

PMEG2005EGW-QX is a member of Nexperia’s PMEG family, a small power MOSFET. It’s an N-channel enhancement-mode transistor intended as a fast, efficient switch in low‑voltage power circuits.
What it is:
- A logic‑level MOSFET suitable for DC‑DC converters, load switches, and protection functions.
- Rated for roughly 20 V drain‑to‑source, with a few amperes of continuous current in typical use; Rds(on) is designed to be low to minimize conduction loss.
- Gate threshold is low enough for practical logic‑level drive, though check the datasheet for exact drive requirements.
Package and marking:
- The “-QX” suffix designates a specific RoHS/pb‑free package variant and footprint. Pinout is G, D, S (or as specified); consult the datasheet for the exact arrangement.
Typical use:
- Switching transistor in buck/boost converters, high‑side or low‑side switch, or protection circuits in compact boards.
Important:
- Always verify the exact electrical ratings (Vds, Id, Rds(on)), package, and drive conditions in the PMEG2005EGW‑QX datasheet, since variant revisions exist.

PMEG2005EGW-QX is a Schottky barrier diode. Key features:
- Reverse voltage (VR): 20 V
- Average forward current (IF(AV)): 0.5 A
- Very low forward voltage drop (Schottky), improving efficiency
- Ultra-fast switching with negligible reverse recovery
- Low leakage current
- RoHS compliant, compact surface-mount package (QX code)
- Wide operating temperature range (typical -55°C to +125°C)
Typical uses: reverse-polarity protection, OR-ing, and high-efficiency rectification in DC–DC converters and power supplies. For exact electrical specs, refer to the datasheet.

SOT-23 (SC-70-3) three-pin surface-mount package.

- Pin count: 2 pins (anode and cathode).
- Function: Surface-mount Schottky barrier rectifier diode (PMEG2005EGW-QX) used for fast, low-drop rectification and reverse-polarity protection in power/supply applications.

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company that designs and manufactures discrete components (such as MOSFETs, diodes, ESD and protection devices) and related power/logic devices. It originated as part of NXP/Philips and is now an independent company headquartered in the Netherlands.

PMEG2005EGW-QX is a P-channel enhancement-mode MOSFET (high-side switch). Typical applications:
- High-side power switching and load-path control in low-voltage, battery-powered systems
- Reverse-polarity and short-circuit protection
- Input switch for DC-DC regulators/PMICs
- OR-ing/ideal-diode power-path configurations in portable devices and consumer electronics
