Product details
Overview
PMEG4010EGWX from Nexperia is a 40 V, 1 A planar Schottky barrier rectifier in SOD123 package, featuring low forward voltage (540 mV typ. at 1 A), low reverse leakage (30 µA typ. at 40 V), and integrated guard ring for stress protection-used in DC-DC converters, reverse polarity protection, and low-voltage rectification circuits.
For engineers reviewing the PMEG4010EGWX datasheet, PMEG4010EGWX pinout, PMEG4010EGWX application, or PMEG4010EGWX equivalent, key selection criteria include forward voltage drop under 1 A load, thermal resistance to solder point (190 K/W), junction temperature limit (150 °C), and SOD123 footprint compatibility with high-density 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 contact and thin epitaxial layer design.
It operates as a unidirectional power rectifier with no switching control logic-functionally defined by forward conduction threshold, reverse blocking capability up to 40 V, and pulsed current handling (IFSM = 9 A, tp = 8 ms). Thermal performance is specified for FR4 PCB mounting with defined copper pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage | 540 mV typical at 1 A, 25 °C - enables <0.55 W conduction loss in 1 A continuous paths |
| Reverse Voltage | 40 V maximum - suitable for 24 V nominal systems with 67 % safety margin against transients |
| Reverse Leakage | 30 µA typical at 40 V, 25 °C - minimizes standby power loss in battery-powered applications |
| Junction Temp Limit | 150 °C - allows operation in industrial ambient up to 85 °C with proper PCB thermal relief |
| Thermal Resistance j-sp | 190 K/W - defines temperature rise from junction to cathode solder point on standard FR4 |
| Capacitance | 43 pF typical at 1 V, 1 MHz - supports high-frequency switching in SMPS output stages |
| Peak Forward Surge | 9 A non-repetitive (8 ms) - withstands inrush currents in hot-swap or capacitive-load circuits |
Pinout & Package
Encapsulated in SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connected to PCB copper pour for thermal dissipation and reverse-bias reference |
| 2 | Anode (A) | Positive terminal; carries forward current into load; requires trace width matching 1 A steady-state rating |
Key Features
| Feature | Design Value |
|---|---|
| Guard Ring Integration | Prevents premature edge breakdown under high dv/dt or mechanical stress, improving long-term reliability in automotive-adjacent industrial use |
| Low VF Optimization | 540 mV typ. at 1 A reduces conduction loss by ~35 % vs. standard Schottkys with VF > 800 mV in same package |
| SOD123 Footprint | Standardized 2.675 mm × 1.6 mm outline enables automated placement and reflow compatibility across mainstream SMT lines |
| Pulsed IR Rating | 100 µA max at 40 V ensures stable reverse blocking during short-duration transients without thermal runaway |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Used as synchronous rectifier replacement in 5–24 V buck converter outputs delivering up to 1 A. IC Role / Device Role / Timing Role: Uncontrolled passive rectifier conducting only when anode voltage exceeds cathode by >540 mV. Use Value: Reduces output stage power loss by 0.27 W vs. 800 mV Schottky, improving efficiency by 1.2 % at full load. |
Use Scenario: Placed in series with VIN rail to block reverse connection of 12 V/24 V power supplies. IC Role / Device Role / Timing Role: Forward-conducting path during correct polarity; open-circuit under reverse bias. Use Value: Limits reverse leakage to ≤100 µA, preventing battery drain or IC damage during miswiring. |
| Low-Voltage AC Adapter Rectification | Low-Power IoT Node Power Path |
Use Scenario: Full-wave rectification in compact 5 V/1 A wall adapters using center-tapped transformer. IC Role / Device Role / Timing Role: Half-wave rectifier per leg; conducts during positive half-cycle of secondary winding voltage. Use Value: Enables 5.2 mm × 3.2 mm board area reduction vs. SMA package alternatives while maintaining 1 A rating. |
Use Scenario: Input protection and voltage clamping in battery-powered sensor nodes with USB-C or coin-cell input. IC Role / Device Role / Timing Role: Reverse-blocking element isolating charging circuitry from system rails during sleep mode. Use Value: 30 µA typical reverse current extends shelf life of CR2032-powered devices beyond 10 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS14 | 40 V, 1 A; VF = 550 mV typ.; SOD-123; no guard ring; IR = 500 µA max at 40 V | Higher leakage limits use in ultra-low-power sleep modes; lower surge rating (IFSM = 40 A but less robust edge termination) | Select when cost sensitivity outweighs leakage or transient immunity requirements |
| ON Semiconductor SB140 | 40 V, 1 A; VF = 500 mV typ.; DO-214AC (SMA); IR = 500 µA max; Rth(j-a) = 70 K/W (board-mounted) | Larger footprint; better thermal dissipation in free air; unsuitable for space-constrained layouts | Select when board-level thermal management prioritizes junction-to-ambient over density |
Compared with SS14 and SB140, PMEG4010EGWX offers the lowest combination of leakage (30 µA typ.) and thermal resistance to solder point (190 K/W), making it optimal for miniaturized, thermally constrained 1 A rectification where standby current and localized heating are critical.

FAQ
What is the maximum continuous forward current rating for PMEG4010EGWX?
The maximum continuous forward current is 1 A at solder point temperature ≤55 °C. This rating assumes FR4 PCB mounting with standard footprint and single-sided 1 cm² cathode copper pad. Exceeding this current without thermal derating risks junction overheating above 150 °C.
Does PMEG4010EGWX have automotive qualification?
No. Per Nexperia's revision history (v.2, Oct 2023), PMEG4010EGWX is explicitly designated as non-automotive. It lacks AEC-Q101 qualification and is not tested to automotive temperature or reliability standards. Automotive designs require -Q suffix variants like PMEG4010EGW-Q.
How does the guard ring affect layout or reliability?
The integrated guard ring suppresses electric field crowding at the die edge, allowing stable 40 V blocking without edge termination structures. Layout requires no special keep-out zones-but cathode pad must match Nexperia's specified 1 cm² copper area to achieve the published Rth(j-sp) = 190 K/W.
Can PMEG4010EGWX replace a standard PN-junction diode in 5 V circuits?
Yes-its 540 mV forward voltage provides ~270 mV lower drop than typical 1 A silicon diodes (e.g., 1N4007: ~810 mV), reducing conduction loss by 0.27 W at 1 A. However, its higher reverse leakage (30 µA vs. <1 µA for PN diodes) may be unacceptable in ultra-low-quiescent-current designs.
