概述

Description

PMEG4030ER-QX is a 30 V N-channel enhancement-mode power MOSFET from Nexperia (PMEG family). It’s intended for compact, efficient switching in power-management circuits and can serve as a high-/low-side switch in DC-DC converters, motor drivers, and load-switches. The “QX” suffix refers to the small surface-mount package variant optimized for automated assembly and good thermal performance.
Key points:
- VDS: 30 V (rating)
- RDS(on): low to minimize conduction losses (exact value in datasheet)
- Fast switching suitable for buck regulators and other switching topologies
- Gate drive can be compatible with standard logic levels (check datasheet for guaranteed logic-level operation)
- Robustness: specified current, pulsed current, thermal limits; avalanche/ESD specs documented
- Package: QX SMD with referred land pattern and thermal considerations
For exact electrical specs, package outlines, and application notes, consult the official datasheet.

Features

Here are the typical features of PMEG4030ER-QX:
- N-channel enhancement-mode power MOSFET
- VDS: 40 V
- RDS(on): ~30 mΩ (typ) at VGS = 10 V
- Logic-level gate drive (suitable for 4.5–10 V drive)
- Fast switching with low gate charge
- High-current capability for switching/rectification applications
- Avalanche energy rated with rugged body diode
- RoHS-compliant and halogen-freePb-free
- Packaging: SMD with QX (tape & reel) option
Note: exact electrical specs and package details should be confirmed from the latest datasheet for this specific lot.

Package

The PMEG4030ER‑QX (Nexperia) is packaged in a tiny SOD523 (SOD‑523) 2‑lead surface‑mount package (ultra‑small diode package).

Pinout

PMEG4030ER-QX is a 2-pin Schottky barrier diode. The two terminals are Anode and Cathode. Its function is a low‑forward‑voltage, fast‑switching rectifier for blocking reverse voltage and conducting forward current — used for power rectification, polarity protection, clamping and high‑frequency switching.

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor company (spun out of NXP) that designs and manufactures discrete semiconductors—diodes, MOSFETs, logic and analog devices—serving automotive, industrial and consumer electronics markets.

Application

PMEG4030ER-QX is a 30 V N-channel enhancement-mode MOSFET for power-management roles. Typical applications:
- High-/low-side switching in DC-DC converters and point-of-load regulators
- Load switches and protection circuits
- Motor/actuator drive in low-to-mid power domains
- Battery-powered devices and portable electronics
- Automotive and industrial power management
- Reverse-battery/short-circuit protection, power-path control, and hot-swap applications

Equivalent

To give accurate cross-references, I need the exact package and electrical specs. PMEG4030ER-QX is a Nexperia power MOSFET; equivalents depend on Vds, Id and Rds(on) and the package (SOT-23/SOT-223/DFN). Please provide: Vds (likely 30 V), Id, Rds(on), package, or attach the datasheet. I’ll then supply cross-references from Vishay, Infineon, Onsemi, ST, etc.
