PMEG4030ER,115

PMEG4030ER,115 is a fast, N-channel enhancement-mode power MOSFET from the PMEG family. It is intended for compact SMD switching roles such as in DC-DC converters, switching regulators, motor drivers, and load switches. Key points:
- N-channel logic-level MOSFET for switching applications
- Typically around 40 V drain–source rating with low on-resistance for efficiency
- Fast switching speed and rugged avalanche performance
- ER suffix usually denotes RoHS-compliant/lead-free variant; 115 is a package/date/lot code and does not change the electrical specs
- Available in common SMT packages (example: SOT-23, DPAK) with standard pinouts
Exact specifications (VDS, ID, RDS(on), VGS(th), Qg, thermal limits) depend on the package version; always consult the latest datasheet for PMEG4030ER,115 for your specific package and operating conditions.

I can’t safely list equivalents without the chip’s key specs (function/type, reverse voltage, forward current, leakage, switching speed and package). Please provide the PMEG4030ER,115 datasheet or those parameters and I’ll give matching drop‑in replacements.

PMEG4030ER,115 features (concise):
- Type: Schottky barrier rectifier
- VRRM: 40 V
- IF(AV): 3 A
- Low forward voltage drop (typical ~0.45 V at 3 A)
- Very fast switching: no reverse-recovery, suitable for high-frequency rectification
- Higher efficiency in SMPS/DC-DC applications
- Reverse leakage current increases with temperature (spec in datasheet)
- Wide operating-temp range: -55°C to +125°C
- RoHS-compliant, Pb-free
- Surface-mount package (compact, suitable for dense layouts) — version with 115 packaging available
Applications: DC-DC converters, polarity/OR-ing, protection diodes in power circuits.

- Pin count: 2 pins.
- Pin assignment: Pin 1 = Anode, Pin 2 = Cathode.
- Function: Schottky barrier diode (low forward-voltage, fast-switching) used for rectification, freewheeling, reverse-polarity protection and low-loss clamping in power and protection circuits.

Manufacturer: Panasonic (Panasonic Semiconductor Solutions / Panasonic Electronic Devices).
What kind of company: Panasonic is a multinational electronics company that designs and manufactures electronic components and semiconductors (including discrete devices such as diodes, transistors and power-management parts), as well as broader consumer and industrial electronics and solutions.

PMEG4030ER,115 is a surface‑mount Schottky barrier rectifier (low forward drop) used for high‑efficiency rectification. Common applications:
- Rectification in switched‑mode power supplies and DC‑DC converters
- Freewheel/flyback diode in buck/boost converters
- Reverse polarity protection on 12–24 V rails and battery circuits
- OR-ing diodes for redundant power sources
- Power‑rail protection in consumer electronics and automotive applications
Note: rating is typically around tens of volts and a few amperes; check datasheet for exact values.

I don’t have web access to verify PMEG4030ER,115’s exact package. Please tell me the manufacturer or allow me to look it up; I’ll then confirm the precise package type (the “ER” usually denotes tape‑and‑reel).
