概述

Description

PMEG4005EJ,115 is a PMEG-series ESD/TVS protection diode. It’s designed to clamp fast transients on sensitive I/O lines (data, USB, CAN, etc.) while keeping line loading low, so it protects upstream ICs without distorting signals.
Notes on the suffixes:
- “4005” and “EJ” denote the device family and variant.
- “115” is typically a packaging/lot or variant code and does not change the electrical function.
Key specs you should check in the datasheet (noting that exact numbers depend on the specific variant):
- Stand-off voltage (V_R) and breakdown voltage (V_BR)
- Clamping voltage (V_C) under surge
- Junction capacitance (C_j) for high-speed signals
- Reverse leakage and ESD rating (HBM/CDM)
- Package type and PCB land pattern
- Operating temperature range
Applications: protecting microcontroller interfaces, USB, HDMI, data buses, and other 5 V logic lines.
If you can share or link the exact datasheet, I can pull the precise V_R, V_BR, V_C, C_j, and packaging details.

Features

PMEG4005EJ,115 is a power MOSFET (N-channel enhancement mode). Typical features include:
- Voltage rating: around 40 V
- On-resistance: ~5 mΩ (typ) at Vgs = 10 V (max ~6–7 mΩ)
- Continuous drain current: several amperes (about 8 A class)
- Gate drive: Vgs ±20 V; threshold ~1–2 V
- Low gate charge for fast switching
- Avalanche rugged / rugged body diode
- Switching speed suitable for SMPS and switching regulators
- Package: Pb-free, commonly D2PAK/TO-252/similar Power-MOSFET package
- Operating temp: wide range (typically -55°C to +150°C)
Note: exact figures vary by variant; refer to the specific datasheet for the 115 version to confirm Vds, Rds(on), Id, and packaging.

Package

PMEG4005EJ,115 comes in a 3‑pin SOT‑23 surface-mount package (SC‑70 family style).

Pinout

PMEG4005EJ,115 is a 2‑pin SMD Schottky barrier diode. Pins:
- Pin 1 = Anode
- Pin 2 = Cathode
Function: low‑forward‑voltage, fast‑recovery Schottky diode used for rectification, reverse‑polarity protection, clamping and general low‑loss switching in power and signal paths (small SOD SMD package).

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor company (headquartered in the Netherlands) that designs and manufactures discrete components, logic ICs and MOSFETs — including power and signal diodes like the PMEG series — supplying automotive, industrial, mobile and consumer electronics markets.

Application

Typical applications of PMEG4005EJ (P‑channel MOSFET):
- High-side load switching and power gating in battery-powered devices
- Input protection (reverse polarity) and simple protection circuits
- Power-management circuits and DC-DC converter switching elements
- PWM switching element in low- to medium-power supplies
- General-purpose use in portable and automotive electronics (LED drivers, MCU peripherals)

Equivalent

I don’t want to give the wrong substitute. Please confirm the key specs you need matched: reverse voltage (VR), forward current (IF), forward drop (VF), package (SOD‑523, SOD‑123, SOT‑23, etc.), and speed/leakage requirements — or paste the PMEG4005EJ datasheet. Once I have that I’ll list drop‑in equivalents (same package and electrical ratings) and close alternatives.
