Product details
Overview
PMEG2005EGWJ from Nexperia is a 20 V, 0.5 A planar Schottky barrier rectifier in SOD123 package, featuring low forward voltage (355 mV typ. at 500 mA), low reverse leakage (40 µA typ. at 20 V), and integrated guard ring for stress protection-used in low-voltage DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2005EGWJ datasheet, PMEG2005EGWJ pinout, PMEG2005EGWJ application, or PMEG2005EGWJ equivalent, this page delivers verified electrical parameters, thermal resistance values (Rth(j-sp) = 190 K/W), diode capacitance (66–80 pF), junction temperature limit (150 °C), and SOD123 footprint details for immediate layout integration.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to enhance ruggedness against voltage transients and electrostatic stress. Its low VF enables high efficiency in low-voltage power paths where conduction loss dominates.
Designed for surface-mount operation on FR4 PCBs, it supports pulsed forward currents up to 7 A (IFRM) and non-repetitive surges of 10 A (IFSM), with thermal performance defined for both standard footprint (Rth(j-a) = 310 K/W) and enhanced cathode pad (Rth(j-sp) = 190 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 355 mV typ. at 500 mA - reduces conduction loss in 3.3 V/5 V rail rectification |
| Reverse Voltage (VR) | 20 V max - suitable for USB-powered, Li-ion battery, and low-voltage SMPS inputs |
| Reverse Current (IR) | 40 µA typ. at 20 V - minimizes standby power loss in always-on systems |
| Diode Capacitance (Cd) | 66–80 pF at 1 V, 1 MHz - limits switching noise and EMI in high-frequency converters |
| Junction Temperature (Tj) | 150 °C max - enables reliable operation in compact, thermally constrained enclosures |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - defines heat transfer efficiency from junction to solder point on cathode pad |
| Peak Forward Surge (IFSM) | 10 A for 8 ms - withstands inrush current during hot-plug or cold-start events |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connected to PCB copper pour for thermal dissipation |
| 2 | Anode (A) | Input terminal; accepts input voltage source or switching node in buck/flyback topologies |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and transient voltage immunity without increasing VF or package size |
| Low thermal resistance to solder point | Rth(j-sp) = 190 K/W enables >0.5 A continuous operation on minimal copper area |
| Low capacitance profile | 66–80 pF supports clean switching in >1 MHz DC-DC controllers without snubbing |
| Pulsed surge capability | 10 A IFSM rating allows use in applications with high capacitive load inrush |
Applications
| USB Power Delivery Input Protection | Li-ion Battery Charging Path |
|---|---|
|
Use Scenario: Prevents reverse current flow from VBUS into host circuitry during cable disconnect or port reconfiguration. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between USB-C receptacle and system power rail. Use Value: 355 mV VF minimizes voltage drop across protection path, preserving ≥4.8 V at 500 mA under worst-case conditions. |
Use Scenario: Isolates charging IC output from battery during charger disable or fault shutdown. IC Role / Device Role / Timing Role: Reverse polarity protection element in linear or switching charger output stage. Use Value: 40 µA IR at 20 V ensures <2 µW standby leakage, critical for multi-week shelf-life in portable devices. |
| Point-of-Load DC-DC Output Rectification | Industrial Sensor Node Power Rail |
|
Use Scenario: Provides synchronous rectification alternative in low-current, space-constrained buck converters. IC Role / Device Role / Timing Role: Freewheeling diode in 3.3 V/0.5 A step-down regulator feeding FPGA I/O banks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 30 V VR, 200 mA IF, VF = 370 mV @ 100 mA - higher VR but lower current rating | Better suited for 12 V input rails with tighter space constraints; not rated for 0.5 A continuous | Select when reverse voltage margin >10 V is required and average current remains ≤200 mA |
| SS12 | 20 V VR, 1 A IF, VF = 500 mV @ 1 A - higher current but +145 mV VF penalty at 500 mA | Acceptable for higher-load applications where thermal headroom exists, but sacrifices efficiency | Choose only if board layout requires SO-23 footprint compatibility and 1 A surge margin is mandatory |
Compared with RB520S-30T1G and SS12, PMEG2005EGWJ uniquely balances 0.5 A continuous current, 20 V rating, and sub-360 mV VF in SOD123-making it optimal for space-limited, efficiency-critical 3.3 V/5 V power paths where thermal resistance to solder point must stay below 200 K/W.

FAQ
What is the maximum continuous forward current for PMEG2005EGWJ at 125 °C ambient?
The device supports 0.5 A continuous forward current (IF) at Tsp ≤ 55 °C per datasheet limiting values. At 125 °C ambient, derating applies: using Rth(j-a) = 310 K/W and Tj(max) = 150 °C, maximum allowable power dissipation drops to ~81 mW, limiting practical IF to approximately 225 mA under natural convection on standard FR4.
Does PMEG2005EGWJ have automotive qualification?
No. Per Nexperia's revision history (v.3, October 2023), PMEG2005EGWJ is explicitly designated as non-automotive. It lacks AEC-Q101 qualification and is not tested to automotive temperature, reliability, or qualification standards. Automotive-grade alternatives require part numbers ending in "-Q".
How does the guard ring affect PCB layout requirements?
Unlike standard Schottky diodes, the integrated guard ring eliminates need for external creepage/clearance enhancement. Layout follows standard SOD123 footprint (Fig. 8), with no additional keep-out zones required around cathode/anode pads-reducing board area and simplifying routing in dense power sections.
Can PMEG2005EGWJ replace BAT54-type diodes in 100 mA signal clamping applications?
No. While electrically compatible at low current, PMEG2005EGWJ is optimized for power rectification-not signal-level clamping. Its higher Cd (66–80 pF vs. BAT54's ~10 pF) degrades high-speed signal integrity, and its VF curve is specified only down to 0.1 mA (90–130 mV), not sub-µA levels needed for precision biasing.
