Product details
Overview
PMEG4005EH from Nexperia is a 40 V, 0.5 A planar Schottky barrier rectifier in SOD123F package, featuring 420–470 mV forward voltage at 500 mA, integrated guard ring for stress protection, and optimized for low-loss DC-to-DC conversion in space-constrained power rails.
For engineers reviewing the PMEG4005EH datasheet, PMEG4005EH pinout, PMEG4005EH application, or PMEG4005EH equivalent, key selection criteria include ultra-low VF performance, thermal resistance (Rth(j-sp) = 60 K/W), reverse leakage (<100 µA at 40 V), and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This MEGA Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low junction-to-solder-point thermal resistance (60 K/W) enables efficient heat transfer on FR4 PCBs with 1 cm² cathode pad.
The device operates with pulsed forward current up to 7 A (IFRM) and non-repetitive surge current up to 10 A (IFSM), while maintaining stable VF across −40 °C to 150 °C junction temperature range and exhibiting diode capacitance of 43–50 pF at 1 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability without breakdown in standard operating conditions. |
| Forward Current (IF) | 0.5 A continuous - Rated for steady-state conduction at Tsp ≤ 55 °C on standard FR4 PCB. |
| Forward Voltage (VF) | 420–470 mV at 500 mA - Enables <150 mW conduction loss, critical for high-efficiency buck converters. |
| Reverse Leakage (IR) | ≤100 µA at 40 V - Low standby power loss in reverse polarity protection circuits. |
| Diode Capacitance (Cd) | 43–50 pF at 1 V - Minimizes switching node ringing and EMI in high-frequency SMPS designs. |
| Junction Temperature (Tj) | −65 to +150 °C - Supports operation in industrial ambient environments without derating. |
| Thermal Resistance (Rth(j-sp)) | 60 K/W - Enables direct thermal coupling to PCB copper, reducing need for heatsinking. |
Pinout & Package
Encapsulated in a compact SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), with flat leads and cathode-marked bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marked by bar on package body; connects to load ground or return path. |
| 2 | Anode (A) | Positive input terminal; accepts input voltage source or switch node; carries full forward current. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 420–470 mV @ 500 mA - Reduces conduction loss by >30% vs. standard Schottkys, improving efficiency in 3.3 V/5 V rails. |
| Integrated guard ring | Edge termination structure - Suppresses localized electric field crowding, enhancing surge robustness and long-term reliability. |
| Flat lead SMD package | SOD123F footprint - Enables automated placement and reflow soldering; compatible with IPC-7351B standard land patterns. |
| Low thermal resistance | Rth(j-sp) = 60 K/W - Allows direct thermal path to PCB copper, supporting 0.5 A operation without forced air or heatsink. |
Applications
| USB Power Delivery Interface | Point-of-Load DC-DC Converter |
|---|---|
Use Scenario: Reverse polarity protection for 5 V/3 A USB-C power input stage. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from miswired adapters. Use Value: 420 mV VF limits voltage drop to <2.1 mV per 5 mA sense current, preserving tight regulation margins. |
Use Scenario: Output rectification in 1 MHz synchronous buck converter powering FPGA core logic. IC Role / Device Role / Timing Role: Freewheeling diode during high-side FET off-time. Use Value: 43–50 pF capacitance minimizes switching node oscillation, reducing EMI filter component count. |
| Industrial Sensor Node Power | IoT Battery Backup Circuit |
Use Scenario: Low-voltage rectification of harvested energy from piezoelectric transducers (0.8–3.0 V AC). IC Role / Device Role / Timing Role: Half-wave rectifier feeding supercapacitor charging path. Use Value: 95–130 mV VF at 0.1 mA enables usable output even below 1 V input, extending harvestable energy range. |
Use Scenario: OR-ing diode between primary Li-ion battery and backup coin cell in asset tracker. IC Role / Device Role / Timing Role: Isolation element preventing backfeed and self-discharge. Use Value: ≤30 µA IR at 10 V reverse bias extends coin cell shelf life beyond 5 years in standby mode. |
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 NSS40050MUTBG | Higher VF (490 mV typ @ 500 mA); same SOD123F package; 40 V VR rating. | Marginally lower efficiency in high-current DC-DC outputs; identical footprint for drop-in replacement. | Prefer when supply chain diversification is required and 70 mV VF penalty is acceptable. |
| Vishay SS14-E3/57T | Higher IF rating (1 A); larger SMA package; VF = 500 mV @ 1 A (not directly comparable at 0.5 A). | Requires PCB redesign due to SMA footprint; better suited for higher-current applications. | Select only if future design scaling to ≥0.8 A is anticipated and board space permits larger package. |
Compared with NSS40050MUTBG and SS14-E3/57T, PMEG4005EH delivers the lowest verified VF at 500 mA in SOD123F, enabling highest efficiency in space-constrained 0.5 A power paths without thermal derating.

FAQ
What is the maximum continuous forward current for PMEG4005EH under standard PCB mounting?
The PMEG4005EH is rated for 0.5 A continuous forward current when mounted on an FR4 PCB with single-sided copper and standard SOD123F footprint, provided solder point temperature remains ≤55 °C. Derating is required above this temperature per the thermal characteristics table.
Does PMEG4005EH have automotive qualification?
No. Per Nexperia's revision history (v.3, October 2022), PMEG4005EH is explicitly designated as non-automotive qualified. Automotive alternatives-such as the PMEG4005EH-Q -are separately qualified and listed on nexperia.com.
How does the integrated guard ring improve reliability?
The guard ring is a doped region surrounding the active Schottky junction that redistributes electric field lines, suppressing premature edge breakdown during voltage transients. This increases surge survivability and extends operational lifetime in noisy power environments.
Can PMEG4005EH be used in reverse polarity protection with 3.3 V input?
Yes. With VF as low as 220–270 mV at 10 mA, the voltage drop across PMEG4005EH is ≤270 mV at typical microcontroller I/O rail currents, preserving sufficient headroom for 3.3 V logic-level operation while blocking reverse current up to 40 V.
