Product details
Overview
PMEG4005EGWJ from Nexperia is a 40 V, 0.5 A planar Schottky barrier rectifier in SOD123 package, featuring low forward voltage (420 mV typ. at 500 mA), low reverse leakage (30 µA typ. at 40 V), and integrated guard ring for stress protection. It serves as a high-efficiency output rectifier in compact DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4005EGWJ datasheet, PMEG4005EGWJ pinout, PMEG4005EGWJ application, or PMEG4005EGWJ equivalent, key selection criteria include forward voltage drop at 500 mA, thermal resistance to solder point (190 K/W), reverse leakage at full rated voltage, and SOD123 footprint compatibility with space-constrained PCB layouts.
Technical Context
This MEGA Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without compromising reverse blocking integrity.
Thermal performance is defined relative to two mounting conditions: Rth(j-sp) = 190 K/W (cathode solder point) and Rth(j-a) = 310 K/W (free air), confirming its suitability for thermally constrained surface-mount applications where localized heat extraction matters more than ambient dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage | 420 mV typical at 500 mA - enables ≥92 % efficiency in 3.3 V–5 V buck converter outputs |
| Reverse Voltage | 40 V maximum - supports input rails up to 36 V nominal with 10 % margin for transients |
| Reverse Leakage | 30 µA typical at 40 V - minimizes standby power loss in battery-backed systems |
| Junction Temperature | 150 °C maximum - allows operation in sealed enclosures up to 120 °C ambient with derating |
| Diode Capacitance | 43 pF typical at 1 V - reduces switching node ringing in >1 MHz DC-DC topologies |
| Peak Forward Surge | 10 A non-repetitive (8 ms) - withstands inrush during hot-plug or cold-start events |
Pinout & Package
Encapsulated in a standard SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm), with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to load/positive rail side; marking bar identifies this terminal; primary heat path to PCB via cathode pad |
| 2 | Anode (A) | Connected to source/negative rail side; carries full forward current; minimal thermal contribution to board |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under voltage stress, improving long-term reliability in industrial power supplies |
| Low thermal resistance to solder point | 190 K/W enables direct thermal coupling to copper pour, supporting 0.5 A continuous current at Tsp ≤ 145 °C |
| Ultra-low forward voltage | 420 mV typ. at 500 mA reduces conduction loss by ~35 % vs. comparable 0.5 A Schottkys with VF > 600 mV |
| Small outline footprint | SOD123 package occupies only 4.3 mm² PCB area - ideal for wearables and IoT sensor nodes with strict size limits |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 20 W USB PD flyback adapter operating at 100 kHz. IC Role / Device Role / Timing Role: Low-loss output rectifier replacing MOSFET gate drive complexity; conducts during transformer demagnetization phase. Use Value: 420 mV VF cuts conduction loss by 180 mW vs. legacy Schottky, raising full-load efficiency from 89.2 % to 90.7 %. |
Use Scenario: Reverse polarity protection for 3.3 V supply rail powering LoRaWAN end-node MCU and RF transceiver. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-rail; blocks reverse connection while adding <10 mV dropout. Use Value: 30 µA IR at 3.3 V ensures <0.1 µW standby loss - critical for 10-year battery life in remote deployments. |
| Point-of-Load DC-DC Module | Automotive Body Control Unit |
Use Scenario: Input protection and hold-up rectification in 12 V → 5 V buck module for FPGA I/O bank. IC Role / Device Role / Timing Role: Clamps negative transients and provides unidirectional current path during input capacitor discharge. Use Value: 10 A IFSM rating absorbs 50 V/100 ns spikes per ISO 7637-2 Pulse 1, eliminating need for parallel TVS. |
Use Scenario: Low-power auxiliary rail conditioning in BCM sub-module powered from vehicle battery (9–16 V). IC Role / Device Role / Timing Role: Isolates backup supply from main rail during ignition-off; prevents backfeed into CAN transceivers. Use Value: 40 V VR rating accommodates load-dump surges up to 35 V without avalanche conduction or parameter shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40050P5T5G | VF = 450 mV typ. at 500 mA; IR = 50 µA typ. at 40 V; same SOD123 package | Higher leakage increases standby loss in battery systems; otherwise interchangeable in AC-DC outputs | Select when sourcing diversity required and 30 µA leakage is not critical to system sleep budget |
| Vishay VS-40CPH05-M3/45 | VF = 490 mV typ. at 500 mA; IR = 15 µA typ. at 40 V; DO-214AC package (larger, leaded) | DO-214AC requires 3× PCB area and manual rework; lower leakage benefits ultra-low-power designs | Choose only if legacy through-hole compatibility or lower IR outweighs size and assembly cost penalties |
Compared with NSS40050P5T5G, PMEG4005EGWJ delivers 30 µA lower leakage and 30 mV lower VF - directly improving battery runtime and thermal headroom. Against VS-40CPH05-M3/45, it trades 15 µA IR advantage for 70 % smaller footprint and automated SMT placement.

FAQ
Is PMEG4005EGWJ qualified for automotive applications?
No. Per Nexperia's revision history (v.3, October 2023), PMEG4005EGWJ is explicitly designated as non-automotive. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction limit. Automotive designs require variants with "-Q" suffix such as PMEG4005EGWJ-Q.
What is the maximum average forward current at 100 °C ambient?
At 100 °C ambient, PMEG4005EGWJ's average forward current is derated to 0.32 A. This is calculated using Rth(j-a) = 310 K/W and Tj(max) = 150 °C: ΔT = 50 K → Ptot = 50 / 310 ≈ 161 mW; with VF ≈ 450 mV, IF(AV) = 161 mW / 0.45 V ≈ 0.32 A.
Does the SOD123 package support hand-soldering repair?
Yes - the SOD123 footprint (2.675 mm × 1.6 mm) is compatible with fine-tip irons and hot-air rework stations. Recommended profile: preheat to 150 °C, ramp to 320 °C peak for ≤10 s, using flux-core solder and thermal relief on cathode pad to avoid delamination.
How does the guard ring affect layout requirements?
The integrated guard ring eliminates need for external field plates or increased creepage spacing. Layout requires only standard IPC-2221 Class B clearance (≥0.25 mm) between anode/cathode traces - no additional guard traces or slots needed around the SOD123 pads.
